How to make DialogFragment width to Fill_Parent

Question

I am working on an android application where I am using DialogFragment to display the dialog but its width is very small. How I can make this width to fill_parent to it ?

public class AddNoteDialogFragment extends DialogFragment {      public AddNoteDialogFragment() {         // Empty constructor required for DialogFragment     }      @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,             Bundle savedInstanceState) {         getDialog().setTitle(getString(R.string.app_name));         View view = inflater.inflate(R.layout.fragment_add_note_dialog,                 container);          return view;     }       @Override     public Dialog onCreateDialog(Bundle savedInstanceState) {         Dialog dialog = super.onCreateDialog(savedInstanceState);          // request a window without the title         dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);          return dialog;     } } 

fragment_add_note_dialog.xml

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@android:color/white"     android:orientation="vertical"     android:paddingBottom="@dimen/activity_vertical_margin"     android:paddingLeft="@dimen/activity_horizontal_margin"     android:paddingRight="@dimen/activity_horizontal_margin"     android:paddingTop="@dimen/activity_vertical_margin" >      <EditText         android:id="@+id/addNoteEditText"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:gravity="top"         android:hint="@string/clock_enter_add_note"         android:imeOptions="actionDone"         android:inputType="textCapSentences|textMultiLine"         android:lines="5" />      <Button         android:id="@+id/submit"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_marginTop="10dp"         android:background="@drawable/login_button"         android:text="@string/submit_button"         android:textColor="@android:color/white" />  </LinearLayout> 

Answer 1

This is the solution I figured out to handle this issue:

@Override public Dialog onCreateDialog(Bundle savedInstanceState) {     Dialog dialog = super.onCreateDialog(savedInstanceState);         dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);      return dialog; }  @Override public void onStart() {     super.onStart();      Dialog dialog = getDialog();     if (dialog != null) {        dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));     } } 

Edit:

You can use the code below in onCrateView method of Fragment before return the inflated view.

getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE); getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); 

Answer 2

Have you tried using the answer of Elvis from How to make an alert dialog fill 90% of screen size?

It is the following:

dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

Update:

Above code should be added inside onStart() method of the DialogFragment.
