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();

}

}
