RippleDrawable
Port of Android <ripple> effect for pre lollipop devices with android 14 + (ICS+)
(well, since NineOldAndroids is deprecated, this library become 14 + only)
Features
- XML inflating
- Ripple supports different shapes
- Custom drawable loader
- Define your custom drawable tags
Implementation
Create your desirable ripple.xml in drawable/ folder
<?xml version="1.0" encoding="utf-8"?>
<ripple
xmlns:android="http://schemas.android.com/apk/res/android"
android:color="@color/ripple_material_light"> <!-- ripple color -->
<!-- for Floating Action Button -->
<item>
<shape android:shape="oval">
<solid android:color="@color/accent_material_dark"/>
</shape>
</item>
</ripple>
Secondly we need to inflate RippleDrawable and intercept View touches
see LollipopDrawablesCompat and DrawableHotspotTouch for inflating and interception sequently. Here is sample:
public class SampleActivity extends AppCompatActivity {
private FloatingActionButton mActionButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sample);
mActionButton = (FloatingActionButton) findViewById(R.id.fab);
mActionButton.setBackgroundDrawable(getDrawable2(R.drawable.fab_background));
mActionButton.setClickable(true);// if we don't set it true, ripple will not be played
mActionButton.setOnTouchListener(
new DrawableHotspotTouch((LollipopDrawable) mActionButton.getBackground()));
}
/**
* {@link #getDrawable(int)} is already taken by Android API
* and method is final, so we need to give another name :(
*/
public Drawable getDrawable2(int id){
return LollipopDrawablesCompat.getDrawable(getResources(), id, getTheme());
}
}Thats it!
##Dependency
root build.gradle add a repository
repositories {
maven {
url "https://jitpack.io"
}
}and in application module just add
dependencies {
compile 'com.github.ozodrukh:RippleDrawable:2.0.0'
}a little bit more
you can inflate and create your own Drawableclasses, here is tips & tricks
1 extend your Drawable from LollipopDrawable
public class LayerDrawable extends LollipopDrawable {2 implement your own inflation
public void inflate(Resources r, XmlPullParser parser, AttributeSet attrs, Resources.Theme theme);3 Register your LollipopDrawable
static {
LollipopDrawablesCompat.registerDrawable(RippleDrawable.class, "ripple");
}4 inflate it!
LollipopDrawablesCompat.getDrawable(getResources(), R.drawable.custom_drawable, getTheme());License
