How can i drag a custom view inside the SurfaceView. Touch events are not dispatched to child custom view from SurfaceView or child view's onTouchEvent is not called.

Try this code
public class MoveViewTouchListener implements View.OnTouchListener
{
private GestureDetector mGestureDetector;
private View mView;
public MoveViewTouchListener(View view)
{
mGestureDetector = new GestureDetector(view.getContext(), mGestureListener);
mView = view;
}
@Override
public boolean onTouch(View v, MotionEvent event)
{
return mGestureDetector.onTouchEvent(event);
}
private GestureDetector.OnGestureListener mGestureListener = new GestureDetector.SimpleOnGestureListener()
{
private float mMotionDownX, mMotionDownY;
@Override
public boolean onDown(MotionEvent e)
{
mMotionDownX = e.getRawX() - mView.getTranslationX();
mMotionDownY = e.getRawY() - mView.getTranslationY();
return true;
}
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY)
{
mView.setTranslationX(e2.getRawX() - mMotionDownX);
mView.setTranslationY(e2.getRawY() - mMotionDownY);
return true;
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
if (g) {
if (groupselecteditems.contains(mView)) {
mView.setBackgroundColor(Color.TRANSPARENT);
groupselecteditems.remove(mView);
} else {
mView.setBackgroundResource(border);
groupselecteditems.add((MyTextView) mView);
}
} else {
toucheditem = mView;
xcountry = mView.getX();
ycountry = mView.getY();
}
return true;
}
@Override
public void onLongPress(MotionEvent e) {
if (g) {
if (groupselecteditems.size() > 0) {
editGroup();
}
} else {
changtextfeatures((TextView) mView);
}
}
};
}
Call this class with your view
view.setOnTouchListener(new MoveViewTouchListener(view));
