onFling手勢不適用於具有TabHost的活動

Question

我一直在嘗試將onFling手勢添加到由TabHost組成的活動。

我使用TabWidget構建了我的製表符usign xml。這裏是我的代碼

activity1.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <LinearLayout

     <TabWidget android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:id="@android:id/tabs" /> 

     <FrameLayout android:layout_width="match_parent"

       <include layout="@layout/entre_vialidades"/> 
      </LinearLayout> 

     </FrameLayout> 
    </LinearLayout> 

</TabHost> 
</LinearLayout> 

Activity1.java

public class EstablecimientoActivity extends Activity implements GestureDetector.OnGestureListener{ 
    TextView lblE90; 
    TextView lblExxGastos; 
    TabHost tabs; 

    private static final int SWIPE_MIN_DISTANCE = 120; 
    private static final int SWIPE_MAX_OFF_PATH = 250; 
    private static final int SWIPE_THRESHOLD_VELOCITY = 200; 

    private GestureDetector mGestureDetector; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.establecimiento); 

      mGestureDetector = new GestureDetector(this, this, null); 

      initTabGroup(); 


      View establecimientoView = findViewById(R.id.establecimientoView); 

      establecimientoView.setOnTouchListener(new View.OnTouchListener() { 
       public boolean onTouch(View v, MotionEvent event) { 
        if (mGestureDetector.onTouchEvent(event)) { 
         Log.d("On touch", "view establecimiento"); 
         return true; 
        } 
        return false; 
       } 
      }); 




    } 

    private void initTabGroup(){ 

      tabs=(TabHost)findViewById(android.R.id.tabhost); 
      tabs.setup(); 

      TabHost.TabSpec spec=tabs.newTabSpec("tabIdEst"); 
      spec.setContent(R.id.tabIdEst); 
      spec.setIndicator("Identificación del Establecimiento"); 
      tabs.addTab(spec); 

      spec=tabs.newTabSpec("tabRefGeo"); 
      spec.setContent(R.id.tabRefGeo); 
      spec.setIndicator("Referencia Geográfica"); 
      tabs.addTab(spec); 

      spec=tabs.newTabSpec("tabUbEst");

      spec.setIndicator("Entre Vialidades"); 
      tabs.addTab(spec); 


      tabs.setCurrentTab(0); 

    } 



    // Listeners 
    @Override

     Log.d("onDown", "Tap"); 
     return false; 
    } 

    @Override 
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, 
      float velocityY) { 
     Log.d("onFling", e1.toString()); 

     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) { 
      Log.d("onFling","right to left"); 
      Intent intent = new Intent(this.getBaseContext(), 
        Activity2.class); 
      startActivity(intent); 
      this.overridePendingTransition(R.anim.slide_in_right, 
        R.anim.slide_out_left); 
      // left to right swipe 
     } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE 
       && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {

      this.overridePendingTransition(R.anim.slide_in_left, 
        R.anim.slide_out_right);

     return false;

    @Override

     // TODO Auto-generated method stub 

    } 

    @Override 
    public boolean onScroll(MotionEvent arg0, MotionEvent arg1, float arg2, 
      float arg3) { 
     // TODO Auto-generated method stub 
     return false; 
    } 

    @Override

    } 

    @Override 
    public boolean onSingleTapUp(MotionEvent arg0) { 
     // TODO Auto-generated method stub 
     return false; 
    } 

} 

我一直在做一些研究，我只得到了如何刷卡標籤之間。 我只想去另一個活動，我的意思是我想從活動1（包含tabhost）到活動2

我在做什麼錯了？

Answer 1

看一看Horizontal Pager，具體是裏面的方法​​。而不是水平滾動頁面開始一個新的活動。
