答

这是如何添加帮助图标到你的动作栏中的例子

This is an example how you can add HELP icon to your action bar

像下面的菜单文件夹内创建一个XML菜单

Create a menu XML inside your menu folder like the following

<item
    android:id="@+id/help_menu_item"
    android:icon="@android:drawable/ic_menu_help"
    android:title="Help"
    android:showAsAction="ifRoom" />

和您的活动做这样的事情。

And in your activity do something like that

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.help_menu, menu);
    return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case R.id.help_menu_item:
            //do your menu press here       
            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}
