如何在Android的

Question

播放聲音的選擇單選按鈕選項下面這裏字符串時，用戶在選擇手機鈴聲播放選擇..

字符串對話框顯示與單選按鈕：

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

Answer 1

1.Keep您聲音文件在一個數組中。在全球範圍內定義一個表示「音樂」的數組。

int[] music ; 

2.Implement DialogInterface.OnClickListener您的活動（或片段）

3.Initialize在OnCreate中你的聲音清晰度陣列和陣列稱號，並創建一個單一的選擇警告對話框

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on dialog of DialogInterface.OnClickListener看起來應該看起來像這樣

@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; 
    } 
} 

5. playsound方法是這樣的

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