FloatUtil

一个简单的浮窗工具。封装了浮窗的使用方法，并做了系统、版本的兼容处理，帮你绕过权限的限制。

开始

项目使用 jitpack 做开源库的托管，你需要在 .gradle 中添加 jitpack 的仓库。

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

在添加 FloatUtil 的依赖引用：

dependencies {
     compile 'com.github.liuguangli:FloatUtil:-SNAPSHOT'
}

创建一个简单的浮窗

  SimpleView floatView = new SimpleView(this);
  FloatUtil.showFloatView(floatView, null);

SimpleView 是你自定义的 View，就这么简单，浮窗显示出来了。

关闭浮窗

  FloatUtil.hideFloatView(context, SimpleView.class, false);

同一个 View 类，同时只能显示一个实例，关闭的时候指定一个 class 对象便能知道关闭哪个浮窗实例。最后一个参数决定要不要将当前实例缓存，以便下次快速显示并维持状态，false 代表不缓存，true 表示要缓存。

向浮窗传递参数

FloatUtil 提供了一个接口：ParamReceiver。你自定义的 View 实现这个接口便能接收参数。

 public class SimpleViewWitchParam extends FrameLayout implements ParamReceiver {
    public static final java.lang.String PARAM = "PARAM";
    public static final String CONTENT = "content";
    @Override
    public void onParamReceive(Bundle bundle) {
        // 在这个回调方法中接收参数并解析
        if (bundle != null) {
            String param = bundle.getString(PARAM);
            
        }
    }
}

然后在添加这个 SimpleViewWitchParam 到浮窗。

    SimpleViewWitchParam floatView = new SimpleViewWitchParam(this);
    Bundle bundle = new Bundle();
    bundle.putString(SimpleViewWitchParam.PARAM, "我是传过来的参数");
    FloatUtil.showFloatView(floatView, bundle);

指定层级和对齐方式

    SimpleViewWitchParam floatView = new SimpleViewWitchParam(this);
    // 居中对齐，浮窗层级为 WindowManager.LayoutParams.TYPE_TOAST
    FloatUtil.showFloatView(floatView, Gravity.CENTER,WindowManager.LayoutParams.TYPE_TOAST , null);

浮窗类型 type 决定了浮窗的层级，关于浮窗层级的详细理解可以参考我的博客:《浮窗开发之窗口层级》, Android 系统对窗体的某些层级有权限限制，例如 WindowManager.LayoutParams.TYPE_PHONE 类型的窗体需要授权。

智能浮窗（突破授权）

FloatUtil 提供智能方式添加浮窗，针对特定的系统版本、机型为你选择合适的浮窗 type ，越过授权（详细参考我的博客：越过用户授权使用浮窗)，你不需要再去关注复杂的处理过程。

    SimpleViewWitchParam floatView = new SimpleViewWitchParam(this);
    Bundle bundle = new Bundle();
    bundle.putString(SimpleViewWitchParam.PARAM, "智能浮窗");
    // 指定浮窗显示的位置
    Point point = new Point();
    point.x = 0;
    point.y = 0;
    FloatUtil.showSmartFloat(floatView, Gravity.CENTER, point, bundle);
