Adding ripple effect for View in onClick

Hello I am trying to add a ripple effect onClick method for View, but this one no working. All my items having an ID, but I don't know how to call it

Here is a code.

@Override
public void onClick(View v) {
int[] attrs = new int[]{R.attr.selectableItemBackground};
TypedArray typedArray = getActivity().obtainStyledAttributes(attrs);
int backgroundResource = typedArray.getResourceId(0, 0);
v.setBackgroundResource(backgroundResource);

switch (v.getId()) {
case ACTION_PLAY_ID:
Log.d(MainActivity.TAG, getString(R.string.detail_action_play));
v.setBackgroundResource(backgroundResource);
Intent intent = new Intent(getActivity(), PlayerActivity.class);
intent.putExtra(Video.VIDEO_TAG, videoModel);
startActivity(intent);

break;
case ACTION_BOOKMARK_ID:
if (bookmarked) {
v.setBackgroundResource(backgroundResource);
deleteFromBookmarks();
((ImageView) v).setImageDrawable(res.getDrawable(R.drawable.star_outline));
} else {
v.setBackgroundResource(backgroundResource);
addToBookmarks();
((ImageView) v).setImageDrawable(res.getDrawable(R.drawable.star));
}
break;
case ACTION_REMINDER_ID:
if (!isReminderSet) {
createReminderDialog((ImageView) v);
} else {
cancelReminder(liveTvProgram.getProgramId());
((ImageView) v).setImageDrawable(res.getDrawable(R.drawable.alarm));
}
break;
}
}


For Lubomir

i have something like this but not working too:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle
savedInstanceState) {
View view = inflater.inflate(R.layout.item_detail, container, false);
ButterKnife.bind(this, view);

View myView = view.findViewById(R.id.actions_container);
int[] attrs = new int[]{R.attr.selectableItemBackground};
TypedArray typedArray = getActivity().obtainStyledAttributes(attrs);
int backgroundResource = typedArray.getResourceId(0, 0);
myView.setBackgroundResource(backgroundResource);

loadImage();
init();

return view;
}


ImageViews(actionbuttons) is creating in java for LinearLayout actions_container

<?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="match_parent">

</RelativeLayout>


</RelativeLayout>


Also my xml ripple effect file is like:

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="@color/dark_primary_color">
<item>
<color android:color="@color/dark_primary_color" />
</item>
<item android:id="@android:id/mask">
<shape android:shape="rectangle">
<solid android:color="?android:colorAccent" />
</shape>
</item>
</ripple>

Answer

Clickable Views

In general, ripple effect for regular buttons will work by default in API 21 and for other touchable views, it can be achieved by specifying

android:background="?android:attr/selectableItemBackground">

In code:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_layout);

    View myView = findViewById(R.id.myView);
    int[] attrs = new int[]{R.attr.selectableItemBackground};
    TypedArray typedArray = getActivity().obtainStyledAttributes(attrs);
    int backgroundResource = typedArray.getResourceId(0, 0);
    myView.setBackgroundResource(backgroundResource);
}
