这就是我所看到的:

请有人给我简单的例子或其他帮助:)创建此方法:-
private static View createTabView(Context context, String tabText) {
View view = LayoutInflater.from(context).inflate(R.layout.custom_tab, null, false);
TextView tv = (TextView) view.findViewById(R.id.tabTitleText);
tv.setText(tabText);
return view;
}
在布局文件夹中创建自定义_tab.xml文件
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabTitleText"
android:layout_width="@dimen/tabWidth"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:clickable="true"
android:paddingTop="@dimen/tabTopPading"
android:paddingBottom="@dimen/tabBottomPading"
android:paddingLeft="@dimen/tabLeftPading"
android:paddingRight="@dimen/tabRightPading"
android:textSize="@dimen/tabTextSize"
android:textColor="@color/themeColor"
android:background="@drawable/tab_selector"/>
答案可能重复在这里
是红色的…:)它说“必须声明元素textview”
tabHost.newTabSpec("Tab1").setIndicator(createTabView(getApplicationContext(),"Tab_name"))
