如何在Android中选择单选按钮选项播放声音

下面是当用户选择“铃声播放”选项时的字符串

要在带有单选按钮的对话框中显示的字符串：

final CharSequence[] items = {" Default", " Vibration", " Best awake ", " Elegent Ringtone " , "Digital phone"};

---

1.将声音文件保存在阵列中。定义一个数组，全局显示“音乐”

int[] music ;

2.在活动（或片段）中实现DialogInterface.OnClickListener

3.在OnCreate中初始化声音分辨率数组和标题数组，并创建单选警报对话框

final CharSequence[] items = {" Default", " Vibration", " Best awake ", " Elegent Ringtone " , "Digital phone"};
music = new int[]{R.raw.one,R.raw.two,R.raw.three,R.raw.four,R.raw.five};

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setPositiveButton("OK",this);
    builder.setNegativeButton("Cancel",this);
    builder.setTitle("Choose Sound");
    builder.setSingleChoiceItems(items,-1,this);
    builder.create();
    builder.show();

4.您的DialogInterface.OnClickListener的onCLick将如下所示

 @Override
public void onClick(DialogInterface dialogInterface, int position) {
  switch (position){
      case DialogInterface.BUTTON_POSITIVE :
          //Do your stuffs
          dialogInterface.dismiss();
          break;
      case DialogInterface.BUTTON_NEGATIVE:
          //Do your stuffs
          dialogInterface.dismiss();
          break;
      default: //Single choice item selected
          playSound(music[position]);
          break;
  }
}

private void playSound(int res) {
    MediaPlayer mediaPlayer = MediaPlayer.create(this,res);
    mediaPlayer.start();
}

5.播放声音的方法是这样的

 @Override
public void onClick(DialogInterface dialogInterface, int position) {
  switch (position){
      case DialogInterface.BUTTON_POSITIVE :
          //Do your stuffs
          dialogInterface.dismiss();
          break;
      case DialogInterface.BUTTON_NEGATIVE:
          //Do your stuffs
          dialogInterface.dismiss();
          break;
      default: //Single choice item selected
          playSound(music[position]);
          break;
  }
}

private void playSound(int res) {
    MediaPlayer mediaPlayer = MediaPlayer.create(this,res);
    mediaPlayer.start();
}
