我如何设置我的代码，以便当我启动tabactivity时它会打开一个特定的选项卡，具体取决于我从哪个意图开始？
即。点击mainactivity中的深蹲按钮 - ＆gt;打开tabactivity并选择squat-tab并显示
大多数谷歌搜索导致人们使用tabhost，所以我不知道我能在这里做什么。
由于

答案 0 :(得分：2)
setSelectedNavigationItem就是你要找的东西 你必须传递一些额外的东西，或者在将数据传递给活动时使用你想要的意图动作。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// position is zero based tab.
int position = 0;
Intent intent = getIntent();
String intentaction = intent.getAction();
if (intentaction != null) {
if (intentaction.equals("hello world")) {
position = 2;
}
}
actionbar.setSelectedNavigationItem(position);
