[英]android : customized action when home logo in action bar si clicked
i changed the logo to an action icon and i want to perform an action when the logo is clicked. 我将徽标更改为操作图标,并且单击徽标后要执行操作。
How can i customize the action when the home logo in action bar is clicked? 单击操作栏中的主页徽标时,如何自定义操作?
thank you 谢谢
In onOptionsItemSelected()
of your activity, watch for an ID of android.R.id.home
-- that will be when the home icon/logo is pressed. 在活动的
onOptionsItemSelected()
中,注意ID为android.R.id.home
,即当按下主页图标/徽标时。 You can then perform whatever action makes sense (eg, move to your app's main screen). 然后,您可以执行任何有意义的操作(例如,移至应用程序的主屏幕)。
