I wish to make a custom AlertDialog full screen like a new activity screen.

Tried these answers and still not working

public void newDialog(final Context c){ final AlertDialog alertDialog; LayoutInflater layoutInflater = LayoutInflater.from(c); dialogueView = layoutInflater.inflate(R.layout.layout_dialogue, null); final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(c); alertDialogBuilder.setView(dialogueView); alertDialog = alertDialogBuilder.create(); dialogueView.findViewById((R.id.closeBtn)).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { alertDialog.dismiss(); } }); alertDialog.show(); }

layout_dialogue.xml 

<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" style="@style/full_screen_dialog" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/frame"> <android.support.design.widget.FloatingActionButton android:id="@+id/closeBtn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/background_sky" android:clickable="true" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintTop_toTopOf="parent" app:srcCompat="@android:drawable/ic_delete" /> </android.support.constraint.ConstraintLayout>

style.xml

<style name="full_screen_dialog" parent="@android:style/Theme.Dialog"> <item name="android:windowNoTitle">true</item> <item name="android:windowFullscreen">true</item> <item name="android:windowIsFloating">true</item> </style>

I had also tried 

android.R.style.Theme_Black_NoTitleBar_Fullscreen ViewGroup.LayoutParams params = getDialog().getWindow().getAttributes(); params.width = WindowManager.LayoutParams.MATCH_PARENT; params.height = WindowManager.LayoutParams.MATCH_PARENT;

None of them are working for me. Any suggestion on how to accomplished it?

  • I think as per your requirements you need to use Dialog instead of Alert Dialog. Dialog provide you to use your own custom view. Commented Feb 19, 2019 at 9:00
  • Yes, I can actually achieve it through Dialog, but can it be done using AlertDialog? Commented Feb 21, 2019 at 2:49

you can use custom style let me show you an example

style.xml

<style name="DialogTheme" parent="android:Theme.Dialog"> <item name="android:layout_width">fill_parent</item> <item name="android:layout_height">fill_parent</item> <!-- No backgrounds, titles or window float --> <item name="android:windowBackground">@color/colorPrimary</item> <item name="android:windowNoTitle">true</item> <item name="android:windowIsFloating">false</item> </style>

Activity.java

AlertDialog.Builder builder = new AlertDialog.Builder(this , R.style.DialogTheme)

Thank for the answer, but how can i use my custom layout with specific button?
your can use custom layout example Dialog dialog = new Dialog(this ,R.style.DialogTheme) dialog.setCustomLayout(R.layout.alert_Layout)
yep, that's a workable way. But, i am trying to do it with alertdialog instead of dialog. Is this possible?
works better with name="android:windowIsFloating">true. Good ans tho. Thanks.
This show black spots at the top and bottom of the dialog

You can use following methodology. (It is defined in Kotlin but you can implement for Java as well)

class FullscreenDialog: DialogFragment() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setStyle(DialogFragment.STYLE_NORMAL, R.style.FullScreenDialogStyle) } override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? { val view = inflater.inflate(R.layout.fragment_no_internet, container, false) return view } override fun onStart() { super.onStart() if(dialog != null) { val width = ViewGroup.LayoutParams.MATCH_PARENT val height = ViewGroup.LayoutParams.MATCH_PARENT dialog.window?.setLayout(width, height) } } }

Add following to your styles.xml

<style name="FullScreenDialogStyle" parent="Theme.AppCompat.Dialog"> <item name="android:windowNoTitle">true</item> <item name="colorPrimaryDark">@color/appPrimaryColor</item> <item name="colorPrimary">@color/appPrimaryColor</item> <!-- Set this to true if you want Full Screen without status bar --> <item name="android:windowFullscreen">true</item> <item name="android:windowIsFloating">false</item> <!-- This is important! Don't forget to set window background --> <item name="android:windowBackground">@null</item> </style>

To show dialog use following:

val fullScreenDialog = FullscreenDialog() fullScreenDialog.isCancelable = false fullScreenDialog.show(supportFragmentManager, "MyTag")

What i have been using for fullscreen dialog with no margin

public class ShareImageEditorDialog extends DialogFragment { @Override public void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Black_NoTitleBar_Fullscreen); } @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View v = inflater.inflate(R.layout.dialog_share_image, container); return v; } }

and to show on button click

new ShareImageEditorDialog().show(((FragmentActivity)activity).getSupportFragmentManager(), "MyTag");
