Java [Android][Tab Intent]如何从Intents打开到tabactivity中的特定选项卡?
如何设置代码,以便在启动tabactivity时,根据启动它的目的,它会打开到特定的选项卡 即,单击mainactivity中的下蹲按钮->打开tabactivity,选择并显示下蹲选项卡 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些什么 谢谢Java [Android][Tab Intent]如何从Intents打开到tabactivity中的特定选项卡?,java,android,android-intent,tabs,Java,Android,Android Intent,Tabs,如何设置代码,以便在启动tabactivity时,根据启动它的目的,它会打开到特定的选项卡 即,单击mainactivity中的下蹲按钮->打开tabactivity,选择并显示下蹲选项卡 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些什么 谢谢 public class tabtry extends Activity implements ActionBar.TabListener { /** * The {@link android.support.v4.view.
