android播放声音的ViewFlipper

您好我正在创建ViewFlipper，如下所示。android播放声音的ViewFlipper

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:background="@android:color/white" 
android:orientation="vertical" > 

<ViewFlipper 
    android:id="@+id/vfShow" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 
</ViewFlipper> 

</LinearLayout>

和处理的事件，如

ViewFlipperSampleActivity.java

public class ViewFlipperSampleActivity extends Activity { 

private static final int SWIPE_MIN_DISTANCE = 120; 
private static final int SWIPE_THRESHOLD_VELOCITY = 200; 

private ViewFlipper vf; 
private Context mContext; 
private final GestureDetector detector = new GestureDetector(
     new MyGestureDetector()); 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.fliper); 
    mContext = this; 
    vf = (ViewFlipper) this.findViewById(R.id.vfShow); 
    vf.setOnTouchListener(new OnTouchListener() { 
     @Override 
     public boolean onTouch(final View view, final MotionEvent event) { 
      detector.onTouchEvent(event); 
      return true; 
     } 
    }); 

    vf.addView(addImageView(R.drawable.a)); 
    vf.addView(addImageView(R.drawable.b)); 
    vf.addView(addImageView(R.drawable.c)); 
    vf.addView(addImageView(R.drawable.d)); 

} 

View addImageView(int resId) { 
    ImageView iv = new ImageView(this); 
    iv.setImageResource(resId); 

    return iv; 
} 

class MyGestureDetector extends SimpleOnGestureListener { 
    @Override 
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
      float velocityY) { 
     try { 

      // right to left swipe 
      if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE 
        && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { 
       vf.setInAnimation(AnimationUtils.loadAnimation(mContext, 
         R.anim.left_in)); 
       vf.setOutAnimation(AnimationUtils.loadAnimation(mContext, 
         R.anim.left_out)); 
       vf.showNext(); 
       return true; 
      } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE 
        && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { 
       vf.setInAnimation(AnimationUtils.loadAnimation(mContext, 
         R.anim.right_in)); 
       vf.setOutAnimation(AnimationUtils.loadAnimation(mContext, 
         R.anim.right_out)); 
       vf.showPrevious(); 
       return true; 
      } 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

     return false; 
    } 
}

}

现在我混淆如何在perticular图像与viewflipper播放声音？请帮助我解决这个问题。

感谢

vf.showNext（）;和vf.showPrevious（）;你可以播放各自的声音 – Braj

但是，我怎么能发挥在这种方法perticular声音？你能举个例子吗？ –

这可能不是完美的，但提供了有关如何实现的想法

class MyGestureDetector extends SimpleOnGestureListener 
{ 
    @Override 
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) 
    { 
     try 
     { 
      if(Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) 
       return false; 
      // right to left swipe 
      if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) 
      {     
       analogflipper.setInAnimation(slideLeftIn); 
       analogflipper.setOutAnimation(slideLeftOut);      

//     System.out.println(" Flipping next... "); 
        if(count < 5) 
        { 
         count += 1; 
         if(isMute) 
          SoundClass.CreateAndPlay(count, AnalogClockTime.this);  
         analogflipper.showNext(); 
        } 
        else 
        { 
         SoundClass.StopAndRelease(count); 
         count = 0; 
         if(isMute) 
          SoundClass.CreateAndPlay(count, AnalogClockTime.this);  
         analogflipper.showNext(); 
        } 
        /*else 
         count = 0;*/ 

       } 
       else if(e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) 
       {      
        analogflipper.setInAnimation(slideRightIn); 
        analogflipper.setOutAnimation(slideRightOut);     

//     System.out.println(" Flipping previous... "); 
        if(count > 0) 
        {

        count -= 1; 
        if(isMute) 
         SoundClass.CreateAndPlay(count, AnalogClockTime.this); 
        analogflipper.showPrevious(); 
       } 
       else 
       { 
        SoundClass.StopAndRelease(count); 
        count = 5; 
        if(isMute) 
         SoundClass.CreateAndPlay(count, AnalogClockTime.this); 
        analogflipper.showPrevious(); 
       } 
       /*else 
        count = 4;*/ 


       } 
      }

嗨，感谢兄弟在你的例子中，你如何声明它是什么？ –

它是一个整数全局变量，用于跟踪当前哪个页面，并且也用于播放页面各自的声音 – Braj

您需要总共5个声音，因此您使用5？我对吗？ –
