この方法でタブを作成しています:
TabSpec tab = tabHost.newTabSpec("Tab1").setIndicator("Tab1",res.getDrawable(R.drawable.tab1_selector));
これは私のセレクターです:
<?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>
ここで、icon_pressedとicon_unpressedは単なるアイコン(png) です。これはうまくいきます。ただし、アイコンとタイトルを設定する代わりに、レイアウトだけを設定するために使用したいと思います(タイトルとアイコンを設定できます)。だから私はこれを試しました:
<?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>
ここで、layout_pressedとlayout_unpressedは次のようなレイアウトです。
<?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>
そして奇妙なことに、実行時にアプリがエラーをスローします:

TabHost タブで setIndicator(selector with layouts) を使用できないのはどういう意味ですか?
