Questions about the width of the android dialog box cannot be covered full screen

This is basically the case when you need to make a custom dialog box with a width full screen.

Alertdialog dialog = new Alertdialog.builder (context). Create ();        Dialog.show ();        window window = Dialog.getwindow ();        Windowmanager.layoutparams LP = Window.getattributes ();        Lp.width = WindowManager.LayoutParams.MATCH_PARENT;        Window.setattributes (LP); Window.setwindowanimations (R.style.dialogwindowanim);//Animation Window.setcontentview (R.layout.layout_mine_bank_del) ;//Layout window.setgravity (Gravity.center);

I've never had a problem before, and I didn't use it until this time.

"Apptheme.noactionbar"

Theme, at more than 5.0 mobile phones found the width can not be covered; If you set the location at the bottom

Window.setgravity (Gravity.bottom);

There is also a distance at the bottom.

Very depressed, tried the other way:

Window.getdecorview (). setpadding (0, 0, 0, 0);

Or

Window.setlayout (ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

Or

window window = GetWindow (); Windowmanager.layoutparams WLP = window.getattributes ();D isplay d = Window.getwindowmanager (). GetDefaultDisplay ();// Gets the screen width wlp.width = (int) (D.getwidth ());//width is set;d as a percentage of the screen size. GetWidth () This method has been discarded wlp.gravity = gravity.center; Window.setattributes (WLP);

But they have not been able to succeed. Until today, I accidentally saw this in a blog to solve the problem.

Window.setbackgrounddrawableresource (Android. R.color.transparent);

Add this sentence to the no problem, haha!

By the way, just like that, the custom dialog box needs to first

Dialog.show ();

It's OK, or it'll go wrong. Another way to customize through inheritance is to show the last face.

public class Mydialog extends alertdialog{public mydialog (context context) {super (context);       } @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);    This.setcontentview (R.layout.my_dialog); }}

This kind of use is also relatively simple, flexibility or

Final Mydialog Mydialog = new Mydialog (context); Mydialog.setmsg ("Test Show custom Dialog box"); Mydialog.setonpositivelistener ("Know",    New View.onclicklistener () {@Override public void OnClick (View v) {mydialog.cancel (); }}); Mydialog.show ();
