Android get full width for custom Dialog

You need to get the current Window and set it's LayoutParams like so:

Dialog d=new Dialog(mContext);..................myDialog.show();Window window = myDialog.getWindow();window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

Alternative(if above solution does't works)

In case above code not works well you can use a workaround

styles.xml

<style name="mydialog"></style>

Java

Dialog d=new Dialog(mContext,R.style.mydialog);..................myDialog.show();Window window = myDialog.getWindow();window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

Two ways this can be done, first one in style.xml and second in code:

1. Add as below in style.xml, alter the value(currently 90%) to meet your needs.

<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">    <item name="android:windowMinWidthMajor">90%</item>    <item name="android:windowMinWidthMinor">90%</item></style>

2. Add setlayout to match_parent

 final Dialog contacts_dialog = new Dialog(ActivityGroup.this, R.style.theme_sms_receive_dialog); contacts_dialog.setContentView(R.layout.dialog_schedule_date_time);

getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT); contacts_dialog.setCancelable(true); contacts_dialog.setCanceledOnTouchOutside(true); contacts_dialog.show();

For full width dialog you can create custom style for dialog. Code is given below for full width dialog:

<style name="Custom_Dialog" parent="ThemeOverlay.AppCompat.Light" >    <item name="windowMinWidthMajor">100%</item>    <item name="windowMinWidthMinor">65%</item></style>

To assign this style to the dialog's constructor, add this to onCreate() method right after setContentView():

getWindow()    .setLayout(        ViewGroup.LayoutParams.FILL_PARENT,        ViewGroup.LayoutParams.WRAP_CONTENT    );
