Question

Write a snippet of code that logs or displays the coordinate of the touch event when the finger is pressed on the screen of your App.

Answer 1

The code has been written using the onCreate Bundle and it is the easiest way we could do the certain tasks performed below:

Activity Code:

@Override

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

final TextView tv = (TextView)findViewById(R.id.tv);

// It will listen to all the touch activities

final View touch = findViewById(R.id.touch);

touch.setOnTouchListener(new View.OnTouchListener() {

@Override

public boolean onTouch(View view, MotionEvent ev) {

//Returning the touched co-ordinates

tv.setText("Co-ordinates of Area Touched : " +String.valueOf(ev.getX()) + "X" + String.valueOf(ev.getY()));

return true;

}

});

}

Layout Code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android:id"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/touch"
android:background="#fff"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<TextView
android:id="@+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Getting Co-ordinates"
/>
</LinearLayout>
