使用活動代替片段的TabLayout

Question

是否可以在應用中使用多個活動而不是片段創建一個滑動的TabLayout？我有兩個活動正在嘗試使用可滑動的TabLayout創建應用程序。我正在尋找網絡，但還找不到。如果可以構建，任何人都可以提供一些鏈接或教程嗎？

從GestureDetector和OnSwipeTouchListener：來自第二源

public class MainActivity extends Activity { 

    private GestureDetectorCompat mDetector; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mDetector = new GestureDetectorCompat(this, new MyGestureListener()); 
    } 

    @Override 
    public boolean onTouchEvent(MotionEvent event){ 
     this.mDetector.onTouchEvent(event); 
     return super.onTouchEvent(event); 
    } 

    class MyGestureListener extends GestureDetector.SimpleOnGestureListener { 
     private static final String DEBUG_TAG = "Gestures"; 

     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() { 
    }   
} 

用法：

imageView.setOnTouchListener(new OnSwipeTouchListener() { 
    public void onSwipeTop() { 
     Toast.makeText(MyActivity.this, "top", Toast.LENGTH_SHORT).show(); 
    } 
    public void onSwipeRight() { 
     Toast.makeText(MyActivity.this, "right", Toast.LENGTH_SHORT).show(); 
     Intent intent = new Intent(this, SecondActivity.class); 
     startActivity(intent); 
    } 
    public void onSwipeLeft() { 
     Toast.makeText(MyActivity.this, "left", Toast.LENGTH_SHORT).show(); 
     Intent intent = new Intent(this, FirstActivity.class); 
     startActivity(intent); 
    } 
    public void onSwipeBottom() { 
     Toast.makeText(MyActivity.this, "bottom", Toast.LENGTH_SHORT).show(); 
    } 

    public boolean onTouch(View v, MotionEvent event) { 
     return gestureDetector.onTouchEvent(event); 
    } 
});

是的 - 雖然可能，但效果並不明顯。這將像用2-3年前的解決方案解決您的問題。如果你仍然想繼續，你可以參考以下鏈接： http://www.mkyong.com/android/android-tablayout-example/ 這應該有助於你理解。
