I have tried many example but no one solve this.
please refer to screen shot so you will understand very easy,what my problem is.
"As you see - Dialog appear with unexpected margin"

i have also try this

> 
> **Window window = dialog.getWindow();
>  window.setLayout(AppBarLayout.LayoutParams.WRAP\_CONTENT, 
>  AppBarLayout.LayoutParams.WRAP\_CONTENT);
>  window.setGravity(Gravity.CENTER);**
> 
> 
> 

java code is - 

```
final Dialog dialog = new Dialog(MainActivity.this);
            dialog.setContentView(R.layout.dialogforgot_password);
            final EditText et_emailforgot = (EditText)dialog.findViewById(R.id.et_EnterMail);
            final Button bt_SubmitForgotPass = (Button)dialog.findViewById(R.id.bt_SubmitForgotButton);
            final TextView ForgotHeading = (TextView)dialog.findViewById(R.id.tv_forgotpasswordHeading);
            final TextView PleaseEnterurMail = (TextView)dialog.findViewById(R.id.tv_Enteruremail);
            et_emailforgot.setTypeface(Lato_Regular);
            PleaseEnterurMail.setTypeface(Lato_Regular);
            ForgotHeading.setTypeface(Lato_Bold);
            bt_SubmitForgotPass.setTypeface(Lato_Bold);
            dialog.show();
