What is the use of dismiss method in dialog
Editor to share with you what is the use of the dismiss method in dialog, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
Dismiss: probably just delete the view, call the Onstop callback, and set mShowing to false. It is recommended to use dismiss, which is one less judgment than cancel, which is generally sufficient, of course, if you have a CancelListener, then use cancel.
Dialogdismiss coding
VoiddismissDialog () {
If (mDecor==null | |! mShowing) {
Return
}
If (mWindow.isDestroyed ()) {
Log.e (TAG, "TriedtodismissDialog () buttheDialog'swindowwasalreadydestroyed!")
Return
}
Try {
MWindowManager.removeViewImmediate (mDecor)
} finally {
If (mActionModekeeper null) {
MActionMode.finish ()
}
MDecor=null
MWindow.closeAllPanels ()
OnStop ()
MShowing=false
SendDismissMessage ()
}
Android dialog disappears: dismiss, cancel, hide
In our opinion, the effect of dismiss is the same as that of cancel, but from the point of view of the source code, dismiss is called in cancel, and you can listen to cancelListener if you call cancel.
Dismiss can be in any thread and the dialog object is destroyed.
Hide only hides the dialog box and does not destroy it. If you plan to use this method to destroy the dialog box, there will be a problem, and the crash log will appear when the Activity is destroyed, because when the Activity is destroyed, you need to close the dialog box. As you can see from the source code, hide just hides view. (gone).
