OnClickListener - x,y location of event?

Question

I have a custom view derived from View. I'd like to be notified when the view is clicked, and the x,y location of where the click happened. Same for long-clicks.

Looks like to do this, I need to override onTouchEvent(). Is there no way to get the x,y location of the event from an OnClickListener instead, though?

If not, what's a good way of telling if a motion event is a 'real' click vs a long-click etc? The onTouchEvent generates many events in rapid succession etc.

Answer 1

Thank you. That was exactly what I was looking for. My code now is:

imageView.setOnTouchListener(new View.OnTouchListener() {         @Override         public boolean onTouch(View v, MotionEvent event) {             if (event.getAction() == MotionEvent.ACTION_DOWN){                 textView.setText("Touch coordinates : " +                         String.valueOf(event.getX()) + "x" + String.valueOf(event.getY()));             }             return true;         }     }); 

which does precisely what Mark asked for...

Full example

The other answers are missing some details. Here is a full example.

public class MainActivity extends AppCompatActivity {      // class member variable to save the X,Y coordinates     private float[] lastTouchDownXY = new float[2];      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);          // add both a touch listener and a click listener         View myView = findViewById(R.id.my_view);         myView.setOnTouchListener(touchListener);         myView.setOnClickListener(clickListener);     }      // the purpose of the touch listener is just to store the touch X,Y coordinates     View.OnTouchListener touchListener = new View.OnTouchListener() {         @Override         public boolean onTouch(View v, MotionEvent event) {              // save the X,Y coordinates             if (event.getActionMasked() == MotionEvent.ACTION_DOWN) {                 lastTouchDownXY[0] = event.getX();                 lastTouchDownXY[1] = event.getY();             }              // let the touch event pass on to whoever needs it             return false;         }     };      View.OnClickListener clickListener = new View.OnClickListener() {         @Override         public void onClick(View v) {             // retrieve the stored coordinates             float x = lastTouchDownXY[0];             float y = lastTouchDownXY[1];              // use the coordinates for whatever             Log.i("TAG", "onLongClick: x = " + x + ", y = " + y);         }     }; } 

Summary

• Add a class variable to store the coordinates
• Save the X,Y coordinates using an OnTouchListener
• Access the X,Y coordinates in the OnClickListener
