//Here is a better and less tightly coupled way to implement an OnClickListener for a RecyclerView. | |
//Snippet of usage: | |
RecyclerView recyclerView = findViewById(R.id.recycler); | |
recyclerView.addOnItemTouchListener( | |
new RecyclerItemClickListener(context, recyclerView ,new RecyclerItemClickListener.OnItemClickListener() { | |
@Override public void onItemClick(View view, int position) { | |
// do whatever | |
} | |
@Override public void onLongItemClick(View view, int position) { | |
// do whatever | |
} | |
}) | |
); | |
//RecyclerItemClickListener implementation: | |
import android.content.Context; | |
import android.support.v7.widget.RecyclerView; | |
import android.view.GestureDetector; | |
import android.view.MotionEvent; | |
import android.view.View; | |
public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener { | |
private OnItemClickListener mListener; | |
public interface OnItemClickListener { | |
public void onItemClick(View view, int position); | |
public void onLongItemClick(View view, int position); | |
} | |
GestureDetector mGestureDetector; | |
public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) { | |
mListener = listener; | |
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { | |
@Override | |
public boolean onSingleTapUp(MotionEvent e) { | |
return true; | |
} | |
@Override | |
public void onLongPress(MotionEvent e) { | |
View child = recyclerView.findChildViewUnder(e.getX(), e.getY()); | |
if (child != null && mListener != null) { | |
mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child)); | |
} | |
} | |
}); | |
} | |
@Override public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) { | |
View childView = view.findChildViewUnder(e.getX(), e.getY()); | |
if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) { | |
mListener.onItemClick(childView, view.getChildAdapterPosition(childView)); | |
return true; | |
} | |
return false; | |
} | |
@Override public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) { } | |
@Override | |
public void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept){} | |
} |
