水平拖動一個ImageView的到另一個活動

Question

我使用的刷卡類去次活動

Main.Java

public class Main extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    View v = findViewById(R.id.main); 


    v.setOnTouchListener(new OnSwipeTouchListener(this) { 
     public void onSwipeTop() { 

      Intent i = new Intent(Main.this, Second.class); 
      startActivity(i); 

     public boolean onTouch(View v, MotionEvent event) { 
      // TODO Auto-generated method stub 
      if (event.getAction() == MotionEvent.ACTION_DOWN) { 
       DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(v); 

       v.startDrag(null, shadowBuilder, v, 0); 
       v.setVisibility(View.INVISIBLE); 
      } 
      return gestureDetector.onTouchEvent(event); 


     } 


     }); 
     } 

OnSwipeTouchListener.java

public abstract class OnSwipeTouchListener implements OnTouchListener { 

protected final GestureDetector gestureDetector; 

public OnSwipeTouchListener (Context ctx){ 
    gestureDetector = new GestureDetector(ctx, new GestureListener()); 
} 

private final class GestureListener extends SimpleOnGestureListener { 

    private static final int SWIPE_THRESHOLD = 100; 
    private static final int SWIPE_VELOCITY_THRESHOLD = 100; 

    @Override 
    public boolean onDown(MotionEvent e) { 
     return true; 
    } 

    @Override 
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { 
     boolean result = false; 
     try { 
      float diffY = e2.getY() - e1.getY(); 
      float diffX = e2.getX() - e1.getX(); 
      if (Math.abs(diffX) > Math.abs(diffY)) { 
       if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) { 
        if (diffX > 0) { 
         onSwipeRight(); 
        } else { 
         onSwipeLeft(); 
        } 
       } 
       result = true; 
      } 
      else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) { 
        if (diffY > 0) { 
         onSwipeBottom(); 
        } else { 
         onSwipeTop(); 
        } 
       } 
       result = true; 

     } catch (Exception exception) { 
      exception.printStackTrace(); 
     } 
     return result; 
    } 
} 

public void onSwipeRight() { 

} 

public void onSwipeLeft() { 
} 

public void onSwipeTop() { 
} 

public void onSwipeBottom() { 
} 

}

main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:gravity="fill" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context="com.joker.charsoo.Main" 
> 

<view 
    android:id="@+id/view1" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="ScrollView" /> 

<LinearLayout 
    android:layout_width="wrap_content" 
    android:layout_height="match_parent" 
    android:layout_centerHorizontal="true" 
    android:orientation="vertical" > 

<ImageView 
    android:id="@+id/main" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentLeft="true" 
    android:layout_alignParentTop="true" 
    android:layout_marginLeft="117dp" 
    android:layout_marginTop="88dp" 
    android:src="@drawable/ic_launcher" /> 

</LinearLayout> 

當我刷卡頂部將進入第二個活動，但ImageView的犯規動！這是醜陋的，它必須移動！ 我想水平拖動圖像，然後轉到第二個活動。

您可以使用imgView.setTranslation(e1.getX()); 將圖像從右向左水平轉移。 詩篇。最低API等級爲11 或者您可以使用此教程圖像滑塊： http://www.androidhive.info/2013/09/android-fullscreen-image-slider-with-swipe-and-pinch-zoom-gestures/ 希望這將幫助你
