Android studio 设置按钮声音开始前的等待时间

我检查按钮时发出声音

    public void Button(View v) {  

        final MediaPlayer mpStart = MediaPlayer.create(this, R.raw.startsound); 
        mpStart.start();
        }

我想在声音开始之前等一段时间。

我该怎么做？

一个解决方案是使用Handler.postdayed（）方法

有关更多信息，请查看此处：

@Override 
public void onClick(View v) {

// This solution will leak memory!  Actually don't use!!!
Handler handler = new Handler(); 
handler.postDelayed(new Runnable() {
     @Override 
     public void run() { 

          final MediaPlayer mpStart = MediaPlayer.create(this, R.raw.startsound); 
          mpStart.start();
     } 
}, 2000); //Here change the time to wait in milliseconds 
}
