Question

Answer 1

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.

Answer 2

public class FullWidthDialogFragment extends AppCompatDialogFragment {
    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NORMAL, R.style.Theme_AppCompat_Light_Dialog_Alert);
    }
}

and if you want much more flexibility can extend AppCompat_Dialog_Alert and custom attributes

Answer 3

For me, it worked when I replaced the LinearLayout parent of the layout inflated in onCreateView by RelativeLayout. No other code change required.

Answer 4

Based on other solutions, I have created my own.

<style name="AppTheme.Dialog.Custom" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowMinWidthMajor">100%</item>
    <item name="android:windowMinWidthMinor">100%</item>
</style>

abstract class BaseDialogFragment : DialogFragment() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setStyle(DialogFragment.STYLE_NO_TITLE, R.style.AppTheme_Dialog_Custom)
    }
}

Answer 5

This is worked for me

Create your custom style :

   <style name="DialogStyle" parent="Base.Theme.AppCompat.Dialog">
    <item name="android:windowMinWidthMajor">97%</item>
    <item name="android:windowMinWidthMinor">97%</item>
   </style>

You can also try use the right parent to match your other dialogs. for example parent="ThemeOverlay.AppCompat.Dialog" and so on.

Use this style in your dialog

public class MessageDialog extends DialogFragment {

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NO_TITLE, R.style.DialogStyle);
}

// your code 
}

Answer 6

    <!-- A blank view to force the layout to be full-width -->
    <View
        android:layout_width="wrap_content"
        android:layout_height="1dp"
        android:layout_gravity="fill_horizontal" />

in the top of my dialog layout did the trick.
