1)这是我的主要活动
package com.art.drumdrum;
import android.app.Activity;
import android.media.AudioManager;
import android.media.SoundPool;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
SoundPool soundPool = null;
int kickId = 0;
int snareId = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button kick = (Button) findViewById(R.id.kick);
Button snare = (Button) findViewById(R.id.snare);
kick.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction()==MotionEvent.ACTION_DOWN)
soundPool.play(kickId, 1, 1, 0, 0, 1);
return false;
}
});
snare.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent Event) {
if (Event.getAction()==MotionEvent.ACTION_DOWN)
soundPool.play(snareId, 1, 1, 0, 0, 1);
return false;
}
});
}
protected void onResume() {
super.onResume();
if (soundPool == null) {
soundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
kickId = soundPool.load(this, R.raw.kick, 1);
snareId = soundPool.load(this, R.raw.snare, 1);
}
}
protected void onPause() {
super.onPause();
if (soundPool != null) {
soundPool.release();
soundPool = null;
}
}
}
