android点击按钮发出声音

第一步：在res目录下建立raw文件夹

第二步：MediaPlayer music = MediaPlayer.create(this, MusicId);

第三步：music.start();

例子如下：

package com.example.test;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ExpandableListView;

public class MainActivity extends Activity {
private ExpandableListView expandableListView;
private MediaPlayer music = null;// 播放器引用
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.btn);

button.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
PlayMusic(R.raw.button_select_sound);
}
});
}
private void PlayMusic(int MusicId) {

music = MediaPlayer.create(this, MusicId);
music.start();

}
