模拟tabhost单击

Question

At the moment I am using this to call the TabHost activity to change tabs:

public void switchTab(int index){
    MintTrack ParentActivity;
    ParentActivity = (MintTrack) this.getParent();
    ParentActivity.getTabHost().setCurrentTab(3);
}

This works well, however, the WebView item in tab "3" remains unfocused, until i touch it...

I need to programatically simulate a click on tab 3 then, as clicking the tab automatically places the focus on the webview ... Any ideas?

Answer 1

试试这个：

getTabHost().getTabWidget().getChildAt(3).performClick();

Answer 2

我不确定它是否会起作用，但您可以尝试在索引3处为孩子请求焦点。

 ParentActivity.getTabHost().getTabWidget().getChildAt(3).requestFocus();
