如果我实现了OnClickListener
,则在单击该按钮时会产生声音效果。在实施OnTouchListener
时,触摸它不会产生声音效果。那么如何在实现OnTouchListener
时启用声音效果?
编辑:
如果使用点击方法,则为以下代码:
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");
}
}
这是如果我使用触摸方法的代码:
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;
}
}
最佳答案
尝试...
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;
}
