將活動更改爲片段，以便「滑動活動」可能

Question

我需要創建一個「滑動活動」，當用戶滑動它時滑動。當用戶向左滑動時，活動應滑動到左側，新活動將從右側進入屏幕。你不能把它放在中間。 Yahoo Mail應用程序也是一樣的。在閱讀郵件時可以看到此信息，並將郵件向左滑動以移至下一封郵件。它如下所示。

在圖像中，可以看到下一個郵件（標題爲「謝謝」）是從側方開口。就我而言，他們是2種不同的活動。我們還可以在當前活動的右側顯示下一個活動的一小部分（如在Windows Phone中），這樣用戶就知道他必須滑動。無論如何，這部分現在是強制性的。

我試圖用this answer來做，但它不是我所追求的。請任何想法嗎？

注意

如果我去的片段，很多班級將被更改或重新完全編碼。

UPDATE

請看看下面的代碼。在這裏，當我滑動SalesInquiry.javaNewLead.java應該打開，具有上述解釋的效果。

Answer 1

您可以使用片段而不是活動

嘗試viewpager庫，請參閱

http://viewpagerindicator.com/

Answer 2

  User GestureDetector and in onFling() method check for the direction of swipe and start the activity accordingly 

      Edited: 
    Try this: 
      GestureDetector gestureDetector = new GestureDetector(
        simpleOnGestureListener); 

     SimpleOnGestureListener simpleOnGestureListener = new SimpleOnGestureListener() { 

       // Move The Background Theme To Select The Theme 
       @Override 
       public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
         float velocityY) { 

        float sensitvity = 100; 

        if ((e1.getX() - e2.getX()) > sensitvity) { 

    //Move right ,start new Activity here 
return true; 
     }else if ((e2.getX() - e1.getX()) > sensitvity) { 
    //Move left ,start new Activity here 
return true; 
     }else{ 
return false ; 
} 
} 

@Override 
    public boolean onTouchEvent(MotionEvent event) { 
     // TODO Auto-generated method stub 
     return (gestureDetector.onTouchEvent(event) || super 
       .onTouchEvent(event)); 
    } 

Answer 3

您可以直接使用片段精確SupportFragment和ViewPager，讓你通過不同的fragements刷卡。它在android.support.v4庫中可用。
