如何使用Android ViewSwitcher？

我正在嘗試使用ViewSwitcher在兩個視圖之間執行切換。一個是ImageView，另一個是MapView。我有一個按鈕，用戶點擊執行此開關，但我的代碼導致錯誤。你們有什麼想法嗎？如何使用Android ViewSwitcher？

很欣賞的幫助！ :)

您是在運行時設置佈局參數還是XML中的所有內容？

您是否嘗試將ViewSwitcher的兩個視圖分別包裝到自己的LinearLayout中？

嗨，謝謝。我重新發布了XML代碼。 – fgs 2010-11-05 13:59:47

哈哈，忘了它。謝謝！ – fgs 2010-11-05 14:09:25

您需要有一個LinearLayout包裝其他所有東西。在這個例子中，我看到了多於一個，但沒有主要的一個。

您的ImageView標記應該位於ViewSwitcher標記下，就像com.google.android.maps.MapView一樣。

將ViewSwitcher小部件添加到您的xml佈局文件。向ViewSwitcher添加添加2個新佈局。

<ViewSwitcher 
     android:id="@+id/viewSwitcher1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentTop="true" 
     android:inAnimation="@android:anim/slide_in_left" > 

     <LinearLayout 
     android:id="@+id/view1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" > 
     <TextView 
      android:id="@+id/text" 
      android:text="This is simplezdscsdc text" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"> 
      </TextView> 

     </LinearLayout> 


    <LinearLayout 
     android:id="@+id/view2" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" > 
     <TextView 
      android:id="@+id/text" 
      android:text="This issdsdsds simplezdscsdc text" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"> 
      </TextView> 

     </LinearLayout> 
    </ViewSwitcher>

在你的活性，添加功能到一個按鈕，在視圖之間切換

viewSwitcher = (ViewSwitcher)findViewById(R.id.viewSwitcher1); 
     myFirstView= findViewById(R.id.view1); 
     mySecondView = findViewById(R.id.view2); 
     button1 = (Button) findViewById(R.id.button1); 
     button1.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       // TODO Auto-generated method stub 
       if (viewSwitcher.getCurrentView() != myFirstView){ 

        viewSwitcher.showPrevious(); 
       } else if (viewSwitcher.getCurrentView() != mySecondView){ 

        viewSwitcher.showNext(); 
       } 
      } 
     });

機器人：inAnimation =「@機器人：動畫/ slide_in_left」允許以便在從左側

滾動
