點擊時自定義按鈕類聲音

Question

在我的應用程序中，當點擊按鈕時我要設置聲音，並且我使用了媒體播放器。但是，當我在很多活動中有很多按鈕時，它非常複雜，所以我想要創建一個按鈕類來擴展按鈕並在事件單擊按鈕中添加聲音。

可能嗎？而且怎麼做呢？

試試這個，

 import android.content.Context; 
     import android.media.MediaPlayer; 
     import android.util.AttributeSet; 
     import android.util.Log; 
     import android.view.View; 
     import android.widget.Button; 

     public class CustomButton extends Button implements View.OnClickListener { 

      Context mContext; 
      public CustomButtonTest(Context context, AttributeSet attrs, int defStyle) { 
       super(context, attrs, defStyle); 
       mContext=context; 
       init(); 
      } 

      public CustomButtonTest(Context context, AttributeSet attrs) { 
       super(context, attrs); 
       mContext=context; 
       init(); 
      } 

      public CustomButtonTest(Context context) { 
       super(context); 
       mContext=context; 
       init(); 
      } 

      private void init(){ 
       setOnClickListener(this); 
      } 

      @Override 
      public void onClick(View v) { 
       // Do something 
       Log.d("TAG","@@@@@@@@@@ onClick"); 
       MediaPlayer mediaPlayer = new MediaPlayer(); 
       mediaPlayer = mediaPlayer.create(mContext, R.raw.xoay_touch_sound); mediaPlayer.start(); 


       /* 

       OR you can try below code also 
       */ 

       /*Log.d("TAG","@@@@@@@@@@ onClick"); 
       int MAX_SOUND_POOL_STREAMS = 4; 


       SoundPool soundPool = new SoundPool(MAX_SOUND_POOL_STREAMS, 
         AudioManager.STREAM_MUSIC, 100); 
       int mySoundId = soundPool.load(mContext, 
         R.raw.xoay_touch_sound, 1); 

       AudioManager audioManager = (AudioManager) mContext.getSystemService(mContext.AUDIO_SERVICE); 
       float actualVolume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); 
       float maxVolume = (float) audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC); 
       float volume = actualVolume/maxVolume; 
       soundPool.play(mySoundId, volume, volume, 1, 0, 1f);*/ 
      } 

     } 

XML

<yourPakageName.CustomButton 
     android:id="@+id/test" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     />
