You can use this function : http://developer.android.com/reference/android/view/View.html#setOnTouchListener(android.view.View.OnTouchListener)
You will probably put it in your onCreate method roughly this way (tested this time) :
Activity onCreate code
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final TextView textView = (TextView)findViewById(R.id.textView);
// this is the view on which you will listen for touch events
final View touchView = findViewById(R.id.touchView);
touchView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
textView.setText("Touch coordinates : " +
String.valueOf(event.getX()) + "x" + String.valueOf(event.getY()));
return true;
}
});
}
layout code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/touchView"
android:background="#f00"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:id="@+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, TestActivity"
/>
</LinearLayout>
Edit: I tried my code and indeed there were a few errors. Anyway, with the layout I give you here it works on my emulator. Can you provide maybe more code/context so I can see what’s wrong?
