Answer 1

@Override public void onStart() {
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null) {
        dialog.getWindow()
                .setLayout((int) (getScreenWidth(getActivity()) * .9), (int)(getScreenHeight(getActivity()) * .6) );
    }
}

public static int getScreenWidth(Activity activity) {
    Point size = new Point();
    activity.getWindowManager().getDefaultDisplay().getSize(size);
    return size.x;
}

public static int getScreenHeight(Activity activity) {
    Point size = new Point();
    activity.getWindowManager().getDefaultDisplay().getSize(size);
    return size.y;
}

example of 90% width and 60% height

Answer 2

In my case width of custom dialog shrinks in size(width) as the content inside dialog becomes smaller in width even though the the width property was set

android:layout_width="match_parent"

I just fixed that width to screen size and now its working according to my requirement

android:layout_width="320dp"

Answer 3

Dialog dialog = new Dialog(BASE_CONTEXT, R.style.Theme_Dialog);  
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);  
dialog.setContentView(R.layout.your_layout);  
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

Answer 4

Instead of using custom dialog , use activity class for this. In manifest file specify the style attribute as below

android:theme="@style/AppThemeDialog"

And add AppThemeDialog in style as below

<style name="AppThemeDialog" parent="Theme.AppCompat">

<item name="colorBackgroundFloating">#ff424242</item> <item name="listPreferredItemPaddingLeft">0dp</item> <item name="android:windowIsFloating">true</item> <item name="listPreferredItemPaddingRight">0dp</item> </style>
