How to set the width of a DialogFragment in percentage?

Question

I have a DialogFragment with an xml layout and I need it to be, let\'s say 75% as wide as the screen. When I look for answers I always find the common weight<

Answer 1

I don't think it is possible to achieve this without using code.

Anyway I'm using this code inside my custom DialogFragment class. Hope it helps.

public void onResume() {
    super.onResume();

    Window window = getDialog().getWindow();
    Point size = new Point();

    Display display = window.getWindowManager().getDefaultDisplay();
    display.getSize(size);

    int width = size.x;

    window.setLayout((int) (width * 0.75), WindowManager.LayoutParams.WRAP_CONTENT);
    window.setGravity(Gravity.CENTER);
}

You can achieve this by setting a style to your dialogfragment on it's onCreate method:

setStyle(DialogFragment.STYLE_NORMAL,R.style.yourStyle);

and in your styles.xml

   <style name="yourStyle" parent="android:Theme.Dialog">
        <item name="android:windowBackground">@drawable/some_background</item>
        <item name="android:windowAnimationStyle">@null</item>
        <item name="android:backgroundDimEnabled">false</item>
        <item name="android:windowMinWidthMajor">75%</item>
        <item name="android:windowMinWidthMinor">75%</item>
        <item name="android:windowNoTitle">true</item>
    </style>
