TabHost setIndicator - 使用佈局，而不是圖標？

我創建標籤是這樣的：TabHost setIndicator - 使用佈局，而不是圖標？

TabSpec tab = tabHost.newTabSpec("Tab1").setIndicator("Tab1",res.getDrawable(R.drawable.tab1_selector));

，這是我的選擇：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tab3Selector"> 

    <item android:drawable="@drawable/icon_pressed" android:state_selected="true"/> 
    <item android:drawable="@drawable/icon_unpressed"/> 

</selector>

其中icon_pressed和icon_unpressed只是圖標（PNG）。這工作正常。不過，我想使用而不是設置圖標和標題來設置佈局（但是我可以在其中設置我的標題+圖標）。所以，我想這一點：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tab3Selector">  
    <item android:drawable="@drawable/layout_pressed" android:state_selected="true"/> 
    <item android:drawable="@drawable/layout_unpressed"/>  
</selector>

其中layout_pressed和layout_unpressed的佈局是這樣的：

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

    <ImageView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:src="@drawable/icon_pressed" 
     android:layout_alignParentLeft="true"/> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_marginLeft="35dp" 
     android:textColor="@color/red" 
     android:textSize="@dimen/fontSmall"/> 

</RelativeLayout>

而且奇怪的是我上運行我的應用程序拋出錯誤：

什麼這是否意味着，我不能在TabHost標籤中使用setIndicator（選擇器與佈局）？

您在File res/drawable-hdpi/layout_pressed處有資源$ NotFoundException。xml檢查你有這個佈局使用的所有資源 - 圖標，顏色，尺寸 – 2013-02-22 10:49:23

你的logcat顯示在res/drawable-hdpi/tab1_selector.xml文件夾中找不到tab1_selector.xml文件 – 2013-02-22 10:55:44

你可以將tab1_selector.xml文件移動到drawable用於測試的-hdpi文件夾 – 2013-02-22 11:00:38

好吧，這可能不是我的錯，但Android的問題。看看我的選擇：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/tab3Selector"> 

    <!-- Layouts (in drawable folder) - don't work !!! --> 

    <item android:drawable="@drawable/pressed_layout" android:state_selected="true"/> 
    <item android:drawable="@drawable/unpressed_layout" android:state_selected="false"/> 

    <!-- Icons (in drawable folder) - work !!! --> 

<!--<item android:drawable="@drawable/pressed_icon" android:state_selected="true"/> --> 
<!--<item android:drawable="@drawable/unpressed_icon"/> --> 

</selector>

看起來像TabHost setIndicator方法簡單即可; T爲選擇與佈局，但可以選擇與圖標...

首先把所有selector.xml文件在res /文件夾繪製

更換

TabSpec tab = tabHost.newTabSpec("Tab1").setIndicator("Tab1",res.getDrawable(R.drawable.tab1_selector));

隨着

TabSpec tab = tabHost.newTabSpec("Tab1").setIndicator("Tab1",getResources().getDrawable(R.drawable.tab1_selector));

好了，當然res是局部變量：res = getResources（）;）那個;沒問題。我所有的選擇器都在可繪製的目錄中，也都在選擇器中使用了佈局。 – qkx 2013-02-22 10:50:16

堆棧跟蹤顯示，Android系統無法發現在他們指定的文件夾的一些資源。你有沒有在適當的文件夾中提供resorces。

我知道這是舊的，但根據TabHost快速鏈接的API頁面here，如果您想對佈局執行任何操作，請使用setIndicator(View view)而不是setIndicator(CharSequence label, Drawable icon)版本。

基於Drawable API，layout不能是Drawable。這就像試圖讓橘子變成蘋果。兩者都是水果，就像layout和icon是你看到的不僅僅是文本而已。但是，它們仍然不同並且處理方式不同。
