我的部分应用扩展了FragmentActivity。
标签有一个图像和一个文本(它有3个标签,但它们有相似的代码,唯一的区别是文字和图像):
mTabManager.addTab("map", mTabHost.newTabSpec("map").setIndicator(context.getString(R.string.map), activity.getResources().getDrawable(R.drawable.maps_tab)), Maps.class, bundlePos);
和maps_tab.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use icon1 -->
<item android:drawable="@drawable/ic_mapa_selected"
android:state_selected="true" />
<!-- When not selected, use icon2-->
<item android:drawable="@drawable/ic_mapa_unselected" />
</selector>
好的,这在Galaxy Ace或HTC Wildfire S等设备中运行良好:
但在其他设备中失败,如Galaxy SII,Galaxy SIII或HTC Desire C
如何解决这种不相容性?
