我的应用程序中有很多按钮，还有很多像钢琴一样的短歌。
但是使用下面的代码，当应用播放歌曲时，按钮点击和App播放声音之间会有延迟大约半秒。
我该如何解决？
public class MainActivity extends Activity {
MediaPlayer mp;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
final Button g1 = (Button) findViewById(R.id.bu1);
final Button g2 = (Button) findViewById(R.id.bu2);
final Button g3 = (Button) findViewById(R.id.bu3);
final Button g4 = (Button) findViewById(R.id.bu4);
final Button g5 = (Button) findViewById(R.id.bu5);
g1.setOnTouchListener(new OnTouchListener() {
MediaPlayer mp = MediaPlayer.create(MainActivity.this, R.raw.closehh);
@Override
public boolean onTouch(View view, MotionEvent motionevent)
{
int action = motionevent.getAction();
if (action == MotionEvent.ACTION_DOWN)
{
mp.start();
mp.seekTo(0);
g1.setBackgroundResource(R.drawable.a0005z);
}
if (action == MotionEvent.ACTION_UP){
g1.setBackgroundResource(R.drawable.a0005);
}
return false;
}
});
g2.setOnTouchListener(new OnTouchListener() {
MediaPlayer mp = MediaPlayer.create(MainActivity.this, R.raw.openhh);
@Override
public boolean onTouch(View view, MotionEvent motionevent)
{
int action = motionevent.getAction();
if (action == MotionEvent.ACTION_DOWN)
{
mp.start();
mp.seekTo(0);
g2.setBackgroundResource(R.drawable.a0005z);
}
if (action == MotionEvent.ACTION_UP){
g2.setBackgroundResource(R.drawable.a0005);
}
return false;
}
});
