如何在触摸按钮时启用声音效果？

Question

If I implement the OnClickListener , the sound effect will work on clicking the button. While on implementing the OnTouchListener the sound effect doesn't work on touching it. So how to enable the sound effect on implementing the OnTouchListener ?

EDIT:

Here is the code if I use clicking approach:

public class CalculatorActivity extends Activity implements OnClickListener
{
    //...
    private Button btn1;
    private EditText edLCD;
    //...

    public void onCreate(Bundle savedInstanceState)
    {
        //...
        btn1 = (Button) findViewById(R.id.d1);
        btn1.setOnClickListener(this);

        edLCD = (EditText) findViewById(R.id.edLCD);
    }

    //...

    public void onClick(View v)
    {
        edLCD.setText(edLCD.getText().toString() + "1");
    }
}

And here is the code if I use touching approach:

public class CalculatorActivity extends Activity implements OnTouchListener
{
    //...
    private Button btn1;
    private EditText edLCD;
    //...

    public void onCreate(Bundle savedInstanceState)
    {
        //...
        btn1 = (Button) findViewById(R.id.d1);
        btn1.setOnTouchListener(this);

        edLCD = (EditText) findViewById(R.id.edLCD);
    }

    //...

    public boolean onTouch(View v, MotionEvent event)
    {
        if(event.getAction() == MotionEvent.ACTION_DOWN)
        {
            edLCD.setText(edLCD.getText().toString() + "1");
        }
        return true;
    }
}

Answer 1

Try...

public boolean onTouch(View v, MotionEvent event)
{
    if(event.getAction() == MotionEvent.ACTION_DOWN)
    {
        v.playSoundEffect(SoundEffectConstants.CLICK);
        edLCD.setText(edLCD.getText().toString() + "1");
    }
    return true;
}
