Android custom dialog Remove black border

There is always a black border in the interface that is displayed when customizing dialog, and the following describes how to remove a black border using a style.

First define the custom style in Values/styles:

  <style name= "Mydialog" parent= "@android: Theme.dialog" >        <item name= "Android:windowframe" > @null < /item>        <item name= "Android:windowbackground" > @drawable/actionbar_item_background</item>        <item name= "Android:windownotitle" >true</item>        <item name= "android:windowisfloating" >true </item>        <item name= "Android:windowcontentoverlay" > @null </item>        <item name= "Android: Background "> #FFF </item>    </style><item name=" Android:windowbackground "> @drawable/ Actionbar_item_background</item> This is the point, only add this after you can remove the black border

Or customize a transparent background image so you can remove the black border!

Code:

Static class Msgdialog extends Dialog implementsandroid.view.View.OnClickListener {private String text;public Msgdialog (Context context, String text) {Super (context, r.style.mydialog); this.text = text;} @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview ( R.layout.login_dialog); TextView txt = (TextView) Findviewbyid (r.id.login_dialog_txt); Txt.settext (text); TextView confirm = (TextView) Findviewbyid (R.ID.LOGIN_DIALOG_BTN); Confirm.setonclicklistener (this);} @Overridepublic void OnClick (View v) {MsgDialog.this.dismiss ();}}
