Custom Dialog in full screen?

Question

Is there any way to make my Dialog view full screen, i.e dialog occupy the entire screen (like an Activity). I tried using the LayoutParams and styles like <item name="android:windowFullscreen">true</item> but nothing seems to be working.

I found a way of getting rid of the Title bar, but couldn't find a way to put a dialog in full screen. So can any one suggest me a way to do it.

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="MyTheme" parent="@android:style/Theme.Dialog">
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowBackground">@color/dialog_background</item>
</style>
</resources>

Answer 1

Give its constructor a non-dialog theme, such as android.R.style.Theme or android.R.style.Theme_Light.

Code by @Bob.

Dialog dialog = new Dialog(context, android.R.style.Theme_Light); 
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.setContentView(R.layout.MyCustomDialogLayout); 
dialog.show();

Answer 2

Following code works in my case :

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.setContentView(R.layout.mydialog2);
dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);

Answer 3

Try this

dialog = new Dialog(context,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);

1.custom your dialog style

 <style name = "MyDialog" >
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowFullscreen">true</item>
        <item name="android:windowIsTranslucent">true</item>
        <item name = "android:windowContentOverlay" >@null</item >
        <item name = "android:colorBackgroundCacheHint" >@null</item >
        <item name = "android:backgroundDimEnabled">true</item>
        <item name = "android:windowBackground" >@android:color/transparent</item >
    </style >

2 :custom your dialog

WindowManager wm = (WindowManager) this.getSystemService(Context.WINDOW_SERVICE);
            int width = wm.getDefaultDisplay().getWidth();
            int height = wm.getDefaultDisplay().getHeight();
            final Dialog dialog = new Dialog(this, R.style.MyDialog);
            View view = LayoutInflater.from(this).inflate(R.layout.layout_dialog, null);

            WindowManager.LayoutParams params = dialog.getWindow().getAttributes();
            params.width = WindowManager.LayoutParams.MATCH_PARENT;
            params.height = WindowManager.LayoutParams.WRAP_CONTENT;

            dialog.setContentView(view);
            dialog.getWindow().setGravity(Gravity.BOTTOM);
            dialog.getWindow().setWindowAnimations(R.style.mydialog_Style);
            dialog.show();

Answer 5

For full screen dialog you should extend DialogFragment it will provide Fragment life cycle methods and this is the recommended way in Android developer documents you can use simple Dialog or AlertDialog also.

When you create dialog instance just use android.R.style.Theme_Black_NoTitleBar_Fullscreen theme with context like this :

Dialog dialog = new Dialog(getActivity(), android.R.style.Theme_Black_NoTitleBar_Fullscreen);

or

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), android.R.style.Theme_Black_NoTitleBar_Fullscreen);

This will show the dialog in full screen.

The answer does not work for me(sdk 21, samsung galaxy s5). After searching and testing, I find that the key point for setting a dialog for fullscreen is the <item name="android:windowIsFloating">false</item> in your dialog style. Most styles of Dialog in sdk set it true! Set it false in a style and use it in

AlertDialog.Builder = new AlertDialog.Builder(getActivity(), R.style.YourStyle);

your style may look like

<style name="YourStyle">
    <item name="android:windowIsFloating">false</item>
    ...
</style>

after setting it false, it should be fullscreen. And more, you can use

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

to set it's height to wrap_content. Hope to help someone.

Answer 7

Try wrapping your dialog_custom_layout.xml into RelativeLayout . That worked for me.

Answer 8

try this code

protected void openDialog() {
        Dialog dialog = new Dialog(this);
        dialog.addContentView(new View(this), (new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)));
        dialog.show();
    }

Answer 9

I'm using a Activity with Dialog theme. In this case, fullscreen worked this way:

int mUIFlag = View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION;

@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().getDecorView().setSystemUiVisibility(mUIFlag);

        getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
        setContentView(R.layout.lockscreen_activity);
}

Answer 10

Create your Custom Dialog as

Dialog dialog = new Dialog(context, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);

Answer 11

Here are steps how to create a full screen dialog with custom layout which occupies the entire screen without any padding from each site.

Step 1: Define your custom dialog layout named layout_fullscreen_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="@color/colorPrimary">

    <!-- Your dialog content here -->

</LinearLayout>

Step 2: Define a new style in styles.xml named FullScreenDialog

<style name="FullScreenDialog" parent="Theme.AppCompat.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
</style>

Step 3: Write a method which creates and shows a dialog

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        createAndShowDialog(this);
    }

    // This method used to create and show a full screen dialog with custom layout.
    public void createAndShowDialog(Context context) {
        Dialog dialog = new Dialog(context, R.style.FullScreenDialog);
        dialog.setContentView(R.layout.layout_fullscreen_dialog);

        WindowManager.LayoutParams layoutParams = dialog.getWindow().getAttributes();
        dialog.getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);
        dialog.getWindow().setAttributes(layoutParams);
        dialog.show();
    }
}
