如何在Android屏幕中禁用选项卡？

Question

你好，你能告诉我如何禁用Android代码的UI中的选项卡..（eclair代码）

Answer 1

If you mean to disable one tab button on TabWidget, then try this code:

// tabHost = ... (get TabHost)
tabHost.getTabWidget().getChildTabViewAt(your_index).setEnabled(false);

If you want to disable tab widget in overall, then:

// tabWidget = ... (get TabWidget)    
tabWidget.setEnabled(false);

Read SDK Help for references:

• TabHost
• TabWidget

Answer 2

Extend TabHost and override methods:

@Override
public void setCurrentTab(int currentTab) {
    if (currentTab != 2)  // position of the tab that should not get selected
        super.setCurrentTab(currentTab);
    else
        // in my case I want to trigger something here but I don't want the button to get selected
}

@Override
public void setCurrentTabByTag(String tag) {
    if (!"\"plus_tab\"".equals(tag))  // tag of the tab that should not get selected
        super.setCurrentTabByTag(tag);
    else
        // in my case I want to trigger something here but I don't want the button to get selected
}
