ActionBarEx
高拓展高自定义性ActionBar,完美替代Android系统默认。
- 支持自定义标题栏布局,支持XML中直接以子布局编写
- 支持自定义前景布局,如显示Loading效果
- 支持自定义背景布局,如图片等
- 支持自定义底部分割线,可以投影效果显示在外部
- 支持自适应状态栏暗亮色图标模式,可实时动态刷新
- 状态栏暗亮色图标模式已适配常见国产ROM,详见StatusBarCompat
- 已封装3种通用样式,可按需引入
项目简介
为什么要写一个ActionBar?官方的和网上开源的那么多。
第一,先说说官方的。官方的在不同系统上的风格并不统一,自定义项太少,不能满足开发需求,所以才涌现了这么多的开源项目。
第二,网上开源的。网上的已有的,我发现的,用过的大部分都是直接封装一个固定样式的布局,或控制控件的显示隐藏,或动态添加需要的控件。但也仅限于自定义左右图标的和中间标题的个数和样式。如果要自定义ActionBar的背景呢?要让背景显示一个图片呢?要让图片延伸到状态栏下面呢?要让背景实现半透明高斯模糊效果呢?要限定按钮图标的大小呢?要自定义中间标题的背景呢?要显示一个搜索框呢?要让搜索框带有清空和搜索图标呢?要自定义搜索框样式呢?要在网络请求时显示一个Loading效果呢?等等这些需求都是无法满足的。而且我相信这样的需求不在少数。
也可能有可以实现的框架,只是我还没发现。
GitHub上Star那么多的框架都无法实现,这个就可以?
要说这个绝对可以实现,肯定是不可能的,但我相信可以实现市面上99%以上的需求。
哪里来的这么大的自信?还是先看看整个项目的层级结构吧。
整个ActionBarEx分为3个基本层级,具体负责功能和命名约定如下:
根层级 | 子层级 | 说明 | 备注 |
---|---|---|---|
BackgroundLayer | 背景层 | 可自定义布局 | |
ActionBarLayer | 主体层 | 垂直线性布局 | |
StatusBar | 状态栏 | ||
TitleBar | 标题栏 | 可自定义布局 | |
BottomLine | 分割线 | ||
ForegroundLayer | 前景层 | 可自定义布局 |
- BackgroundLayer 背景层,负责整个ActionBar背景的绘制,如实现半透明背景或图片背景或高斯模糊背景
- ActionBarLayer 主体层,是以下3个不分的统称:
- StatusBar 系统状态栏占位,可控制单独显示一个背景色,可实现状态栏图片暗色和亮色模式切换
- TitleBar 导航栏占位,用于显示标题图标按钮等,支持自定义布局样式,以实现复杂需求
- BottomLine 底部分割线,可控制分割线颜色和高度
- ForegroundLayer 前景层,用于显示一些特殊的状态,如加载状态LoadingBar,支持自定义布局
别整这么多虚的,先看看疗效
呦吼,看着还不错呀,快告诉我怎么用?
别急呀,我再说说实现细节。
好好,别动手,有话好好说,你把这个规则长方体放下。。。
要说使用方式,还得再明确几个类
- ActionBarEx 这个就是上面说的封装好的分3个层级的基类
- ActionBarCommon 继承自ActionBarEx,标题栏布局为【图标-文字-标题文字-文字-图标】
- ActionBarSearch 继承自ActionBarEx,标题栏布局为【图标-文字-搜索框-文字-图标】
- ActionBarSuper 继承自ActionBarEx
- 支持自定义主标题和副标题显示
- 支持自定义标题位置居中或居左
- 左右分别支持最多5个按钮
- 支持精确自定义每个按钮的边距
集成方式
添加依赖
- 在Project的build.gradle添加仓库地址
allprojects {
repositories {
...
maven { url 'https://www.jitpack.io' }
}
}
- 在Model:app的build.gradle添加框架依赖
最新版本是多少,看下Releases
从2.2.9以后版本去除版本号前的v,引用时需要注意下。
从3.0.0版本开始分离了ActionBarEx和ActionBarCommon/Search。
从3.1.0版本新增ActionBarSuper
dependencies {
// 完全引入
implementation 'com.github.goweii:ActionBarEx:3.2.2'
// 只引入ActionBarEx
implementation 'com.github.goweii.ActionBarEx:actionbarex:3.2.2'
// 引入ActionBarCommon/Search/Super,依赖于ActionBarEx
implementation 'com.github.goweii.ActionBarEx:actionbarex-common:3.2.2'
}
简单需求只需要下面2步就可以了
这里用ActionBarCommon举个例子
- 布局文件引用
<per.goweii.actionbarex.common.ActionBarCommon
android:id="@+id/simple_action_bar_3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:background="#ccffffff"
app:ab_autoImmersion="false"
app:ab_bottomLineColor="@color/line"
app:ab_bottomLineHeight="0dp"
app:ab_foregroundLayerLayout="@layout/loading_bar"
app:ab_statusBarColor="@color/transparent"
app:ab_statusBarMode="dark"
app:ab_statusBarVisible="false"
app:ab_titleBarHeight="48dp"
app:abc_leftIconColor="@color/black"
app:abc_leftIconRes="@mipmap/back"
app:abc_leftText="返回"
app:abc_leftTextPaddingLeft="0dp"
app:abc_leftTextPaddingRight="0dp"
app:abc_rightIconColor="@color/black"
app:abc_rightIconRes="@mipmap/search"
app:abc_rightText="确定"
app:abc_rightTextPaddingLeft="0dp"
app:abc_rightTextPaddingRight="0dp"
app:abc_titleText="这个标题有点长我试试长标题什么样子"
app:abc_titleTextMaxWidth="180dp" />
- 代码中绑定事件
actionBarCommon.setOnLeftIconClickListener(new OnActionBarChildClickListener() {
@Override
public void onClick() {
Toast.makeText(context, "onLeftIconClick", Toast.LENGTH_SHORT).show()
}
});
复杂一点的需求,需要自定义导航栏布局
使用起来是这个样子的
- 自定义布局文件 title_bar_custom.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<ImageView
android:id="@+id/iv_back"
android:layout_width="48dp"
android:layout_height="48dp"
android:padding="15dp"
android:scaleType="fitCenter"
android:src="@mipmap/back" />
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center"
android:text="自定义布局"
android:textColor="@color/white"
android:textSize="17sp" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="right"
android:orientation="horizontal">
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:padding="15dp"
android:scaleType="fitCenter"
android:src="@mipmap/download" />
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:padding="15dp"
android:scaleType="fitCenter"
android:src="@mipmap/delete" />
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:padding="15dp"
android:scaleType="fitCenter"
android:src="@mipmap/more" />
</LinearLayout>
</RelativeLayout>
- 引用布局
<per.goweii.actionbarex.ActionBarEx
android:id="@+id/action_bar_ex"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:background="@drawable/title_bar_custom_bg"
app:ab_bottomLineColor="@color/line"
app:ab_bottomLineHeight="0dp"
app:ab_foregroundLayerLayout="@layout/loading_bar"
app:ab_statusBarColor="@color/transparent"
app:ab_statusBarMode="dark"
app:ab_statusBarVisible="48dp"
app:ab_titleBarLayout="@layout/title_bar_custom" />
- 代码中绑定事件
actionBarEx.getView(R.id.iv_back).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
更加复杂的需求,可能需要自定义子类了
自定义子类需要下面三步,复写2个方法
-
initAttrs(AttributeSet attrs):获取子类的自定义属性,注意不要忘了调用super.initAttrs(attrs);
-
inflateTitleBar():初始化TitleBar导航栏布局
-
自定义点击事件回调
举个例子吧
@Override
protected void initAttrs(AttributeSet attrs) {
super.initAttrs(attrs);
TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.ActionBarCommon);
float titleTextMaxWidthDef = getContext().getResources().getDimension(R.dimen.title_bar_title_text_max_width_def);
float iconPaddingDef = getContext().getResources().getDimension(R.dimen.title_bar_icon_padding_def);
float textSizeDef = getContext().getResources().getDimension(R.dimen.title_bar_text_size_def);
float textPaddingLeftDef = getContext().getResources().getDimension(R.dimen.title_bar_text_padding_left_def);
float textPaddingRightDef = getContext().getResources().getDimension(R.dimen.title_bar_text_padding_right_def);
float titleTextSizeDef = getContext().getResources().getDimension(R.dimen.title_bar_title_text_size_def);
int iconColorDef = ContextCompat.getColor(getContext(), R.color.title_bar_icon_color_def);
int textColorDef = ContextCompat.getColor(getContext(), R.color.title_bar_text_color_def);
int titleTextColorDef = ContextCompat.getColor(getContext(), R.color.title_bar_title_text_color_def);
leftTextClickToFinish = typedArray.getBoolean(R.styleable.ActionBarCommon_abc_leftTextClickToFinish, false);
leftIconClickToFinish = typedArray.getBoolean(R.styleable.ActionBarCommon_abc_leftIconClickToFinish, false);
leftText = typedArray.getString(R.styleable.ActionBarCommon_abc_leftText);
leftTextSize = typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftTextSize, textSizeDef);
leftTextColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_leftTextColor, textColorDef);
leftTextPaddingLeft = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftTextPaddingLeft, textPaddingLeftDef);
leftTextPaddingRight = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftTextPaddingRight, textPaddingRightDef);
leftIconRes = typedArray.getResourceId(R.styleable.ActionBarCommon_abc_leftIconRes, 0);
leftIconColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_leftIconColor, iconColorDef);
leftIconPadding = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftIconPadding, iconPaddingDef);
leftIconMarginLeft = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_leftIconMarginLeft, 0);
rightText = typedArray.getString(R.styleable.ActionBarCommon_abc_rightText);
rightTextSize = typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightTextSize, textSizeDef);
rightTextColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_rightTextColor, textColorDef);
rightTextPaddingLeft = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightTextPaddingLeft, textPaddingLeftDef);
rightTextPaddingRight = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightTextPaddingRight, textPaddingRightDef);
rightIconRes = typedArray.getResourceId(R.styleable.ActionBarCommon_abc_rightIconRes, 0);
rightIconColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_rightIconColor, iconColorDef);
rightIconPadding = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightIconPadding, iconPaddingDef);
rightIconMarginRight = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_rightIconMarginRight, 0);
titleText = typedArray.getString(R.styleable.ActionBarCommon_abc_titleText);
titleTextSize = typedArray.getDimension(R.styleable.ActionBarCommon_abc_titleTextSize, titleTextSizeDef);
titleTextColor = typedArray.getColor(R.styleable.ActionBarCommon_abc_titleTextColor, titleTextColorDef);
titleTextMaxWidth = (int) typedArray.getDimension(R.styleable.ActionBarCommon_abc_titleTextMaxWidth, titleTextMaxWidthDef);
typedArray.recycle();
}
@Override
protected View inflateTitleBar() {
titleBarChild = (RelativeLayout) inflate(getContext(), R.layout.action_bar_title_bar_common, null);
leftIconView = titleBarChild.findViewById(R.id.iv_left);
leftTextView = titleBarChild.findViewById(R.id.tv_left);
titleTextView = titleBarChild.findViewById(R.id.tv_title);
rightTextView = titleBarChild.findViewById(R.id.tv_right);
rightIconView = titleBarChild.findViewById(R.id.iv_right);
LinearLayout.LayoutParams leftIconViewParams = (LinearLayout.LayoutParams) leftIconView.getLayoutParams();
leftIconViewParams.leftMargin = leftIconMarginLeft;
leftIconView.setLayoutParams(leftIconViewParams);
if (leftIconRes > 0) {
leftIconView.setVisibility(VISIBLE);
leftIconView.setPadding(leftIconPadding, leftIconPadding, leftIconPadding, leftIconPadding);
leftIconView.setImageResource(leftIconRes);
leftIconView.setColorFilter(leftIconColor);
if (leftIconClickToFinish) {
leftIconView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finishActivity();
}
});
}
} else {
leftIconView.setVisibility(GONE);
}
if (!TextUtils.isEmpty(leftText)) {
leftTextView.setVisibility(VISIBLE);
leftTextView.setText(leftText);
leftTextView.setTextColor(leftTextColor);
leftTextView.setTextSize(TypedValue.COMPLEX_UNIT_PX, leftTextSize);
leftTextView.setPadding(leftTextPaddingLeft, 0, leftTextPaddingRight, 0);

rightIconView.setVisibility(VISIBLE);
rightIconView.setPadding(rightIconPadding, rightIconPadding, rightIconPadding, rightIconPadding);

rightIconView.setColorFilter(rightIconColor);

}
return titleBarChild;
}
好吧我承认,我只是复制了下ActionBarCommon的实现代码,不过流程就是这么个流程,还是很简单的。
哎,等等,前景层怎么用呢?
厉害了,想跳过去,都被你发现了。
看下前面自定义导航栏布局中是不是有这么一句
app:ab_foregroundLayerLayout="@layout/loading_bar"
那这个布局长什么样子呢?
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:visibility="gone"
android:layout_height="50dp">
<me.zhanghai.android.materialprogressbar.MaterialProgressBar
android:id="@+id/loading_bar"
style="@style/loading_bar"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_gravity="bottom"
android:indeterminate="true"
app:mpb_progressStyle="horizontal"
app:mpb_useIntrinsicPadding="false" />
</FrameLayout>
这个其实就是一个1dp高的ProgressBar,用来显示加载中效果
在代码中这样使用就可以了
actionBarEx.getForegroundLayer().setVisibility(View.VISIBLE);
actionBarEx.getForegroundLayer().setVisibility(View.GONE);
是不是很简单?

实现细节
好了,下面上干货。还是从整个层级划分开始说起吧。
先从布局结构重新看下层级划分
- FrameLayout(ActionBarEx本身,继承自FrameLayout)
- ImageView或者自定义布局(背景层BackgroundLayer)
- LinearLayout(主体层ActionBar)
- View(状态栏StatusBar)
- FrameLayout(标题栏TitleBar)
- View(底部分割线BottomLine)
- 自定义布局(前景层ForegroundLayer)
这样是不是对整个结构有了一个更清晰的认识。
从代码上看主要的两个功能
- ActionBarEx(自定义控价,负责显示布局)
- StatusBarUtils(负责系统状态栏的沉浸和图标亮色暗色模式切换)
来先看下ActionBarEx的自定义过程
先看下构造方法都干了那些事
public ActionBarEx(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
this.mContext = context;
mDisplayInfoUtils = DisplayInfoUtils.getInstance(context);
mStatusBarHeight = mDisplayInfoUtils.getStatusBarHeight();
initAttrs(attrs);
makeImmersion();
initView();
}
可以看到初始化了一个DisplayInfoUtils对象,获取了下系统状态栏的高度。
然后调用了3个方法,下面一个一个看下:
initAttrs(AttributeSet attrs)
主要为获取了自定义属性,设置默认值。这都是自定义View的常规操作。
protected void initAttrs(AttributeSet attrs) {
TypedArray typedArray = mContext.obtainStyledAttributes(attrs, R.styleable.ActionBarEx);
float titleBarHeightDef = mContext.getResources().getDimension(R.dimen.title_bar_height_def);
float bottomLineHeightDef = mContext.getResources().getDimension(R.dimen.bottom_line_height_def);
int bottomLineColorDef = ContextCompat.getColor(mContext, R.color.bottom_line_color_def);
int statusBarColorDef = ContextCompat.getColor(mContext, R.color.status_bar_color_def);
mAutoImmersion = typedArray.getBoolean(R.styleable.ActionBarEx_ab_auto_immersion, true);
mBackgroundLayerLayoutRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_background_layer_layout, 0);
mBackgroundLayerImageRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_background_layer_image_res, 0);
mStatusBarVisible = typedArray.getBoolean(R.styleable.ActionBarEx_ab_status_bar_visible, true);
mStatusBarDarkMode = typedArray.getInt(R.styleable.ActionBarEx_ab_status_bar_mode, STATUS_BAR_MODE_LIGHT) == STATUS_BAR_MODE_DARK;
mStatusBarColor = typedArray.getColor(R.styleable.ActionBarEx_ab_status_bar_color, statusBarColorDef);
mTitleBarLayoutRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_title_bar_layout, 0);
mTitleBarHeight = (int) typedArray.getDimension(R.styleable.ActionBarEx_ab_title_bar_height, titleBarHeightDef);
mBottomLineHeight = (int) typedArray.getDimension(R.styleable.ActionBarEx_ab_bottom_line_height, bottomLineHeightDef);
mBottomLineColor = typedArray.getColor(R.styleable.ActionBarEx_ab_bottom_line_color, bottomLineColorDef);
mForegroundLayerLayoutRes = typedArray.getResourceId(R.styleable.ActionBarEx_ab_foreground_layer_layout, 0);
typedArray.recycle();
}
makeImmersion()
看名字可以知道是设置沉浸模式,先贴代码:
private void makeImmersion() {
if (!mAutoImmersion) {
return;
}
Activity activity = getActivity();
if (activity == null) {
return;
}
setSystemStatusBar(activity);
hintSystemActionBar(activity);
}
看最下面2行,分别设置了系统沉浸状态栏和隐藏一同自带的导航栏。
具体如何实现状态栏沉浸的,我就不多介绍了,都是百度的一些零零散散的方法,和看GitHub上一些大神的代码,针对小米魅族VIVO做了适配。并不能保证所有系统都有效。如果你有更好的适配方案,欢迎讨论,或者你可以让mAutoImmersion=false来关闭自动适配,去Activity实现自己的方法
initView()
这个方法是本项目的重点,但很简单,没什么难的。
private void initView() {
// 1 初始化BackgroundLayer
// 1.1 初始化背景图
if (mBackgroundLayerLayoutRes > 0){
mBackgroundLayer = inflate(getContext(), mBackgroundLayerLayoutRes, null);
mBackgroundLayer.setLayoutParams(makeLayerLayoutParams());
addView(mBackgroundLayer);
} else {
if (mBackgroundLayerImageRes > 0) {
ImageView actionBarImageView = new ImageView(mContext);
actionBarImageView.setLayoutParams(makeLayerLayoutParams());
actionBarImageView.setImageResource(mBackgroundLayerImageRes);
actionBarImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
addView(actionBarImageView);
}
}
// 2 初始ContentLayer(ActionBar)
mActionBar = (LinearLayout) inflate(getContext(), R.layout.action_bar, null);
mActionBar.setLayoutParams(makeLayoutParamsWithHeight(getActionBarHeight()));
// 2.1 初始StatusBar
mStatusBar = mActionBar.findViewById(R.id.status_bar);
mStatusBar.setLayoutParams(makeLayoutParamsWithHeight(mStatusBarHeight));
mStatusBar.setBackgroundColor(mStatusBarColor);
mStatusBar.setVisibility(mStatusBarVisible ? VISIBLE : GONE);
// 2.2 初始TitleBar
mTitleBar = mActionBar.findViewById(R.id.title_bar);
mTitleBar.setClickable(true);
mTitleBar.setFocusable(true);
mTitleBar.setFocusableInTouchMode(true);
mTitleBar.setLayoutParams(makeLayoutParamsWithHeight(mTitleBarHeight));
mTitleBarChild = inflateTitleBar();
if (mTitleBarChild != null) {
mTitleBar.addView(mTitleBarChild);
}
// 2.3 初始BottomLine
mBottomLine = mActionBar.findViewById(R.id.bottom_line);
mBottomLine.setLayoutParams(makeLayoutParamsWithHeight(mBottomLineHeight));
mBottomLine.setBackgroundColor(mBottomLineColor);
addView(mActionBar);
// 3 初始ForegroundLayer
if (mForegroundLayerLayoutRes > 0) {
mForegroundLayer = inflate(getContext(), mForegroundLayerLayoutRes, null);
mForegroundLayer.setLayoutParams(makeLayerLayoutParams());
addView(mForegroundLayer);
}
}
这里又有一个inflateTitleBar()方法,就是为了继承自定义而加的,它是这样实现的
protected View inflateTitleBar() {
if (mTitleBarLayoutRes > 0) {
return inflate(getContext(), mTitleBarLayoutRes, null);
}
return null;
}
然后是。?还有然后?哦,没了
一共就干了这么点事,没有实现任何效果,完全是一个空架子。是的,任何效果都需要自定义。
这个ActionBarEx只是划分了下导航栏的层级,限定了下各层级的功能。
当然每个项目肯定都有一个固定风格的设计,不可能每次使用都在布局中添加一个ActionBarEx,再引用一个自定义布局,再在代码中getView拿到控件初始化和绑定事件。稍微复杂点的肯定都是要自定义子类封装的,具体可以参考上面的自定义子类或者直接参考SimpleActionBar或者SearchActionBar的实现。
写在最后
这个完全是个人项目,有几点有必要说明下:
