我的应用程序有四个选项卡，每个选项卡都有不同的活动。我将选项卡与程序的 mainactivity 匹配，并且第一个选项卡默认显示在屏幕上。第一个选项卡显示带有列表视图的公告。此应用程序适用于 Android 3.0 及更高版本，但不适用于 2.3.3。添加选项卡时，它会在 mainactivity 中强制关闭。

    TabHost tabHost = getTabHost();     
    Log.w("mainactivity", "200 ");

    TabSpec tabspec1 = tabHost.newTabSpec("Duyurular");
    Log.w("mainactivity", "201 ");
    tabspec1.setIndicator("Duyuru");
    Log.w("mainactivity", "202 ");
    Intent tab1Intent = new Intent(this, duyurular.class);
    Log.w("mainactivity", "203 ");
    tabspec1.setContent(tab1Intent);
    Log.w("mainactivity", "204 ");
    tabHost.addTab(tabspec1); 
    Log.w("mainactivity", "205 ");

我在 LogCat 上看到 mainactivty 204，但没有看到 205。

看看列表行：

Resources$NotFoundException：资源不是可绘制对象（颜色或路径）：TypedValue{t=0x2/d=0x1010305 a=-1}

该定义"@color/ubsacikmavi似乎不是可绘制的，尽管它必须是一个（参见文档android:background）
