I configured my project so that the default dialog theme for DialogFragments
has a minimum width.
set the app's theme to your custom theme in the AndroidManifest.xml
....alternatively, set the theme of the Activity
hosting the DialogFragment
to your app's custom theme.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.helloworld">
<application
android:name=".App"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme"> <!-- set the app's theme to your custom theme -->
.....
</application>
</manifest>
define your custom theme in values/styles.xml
, and override the default theme used for dialog fragments with one you define yourself.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppTheme" parent="Theme.AppCompat">
<!-- override the default theme for DialogFragments -->
<item name="android:dialogTheme">@style/AppTheme.Dialog</item>
</style>
<!--
configure your custom theme for DialogFragments...
use a theme that has MinWidth, so that the dialog is not "too small"
-->
<style name="AppTheme.Dialog" parent="Theme.AppCompat.Dialog.MinWidth">
<!-- override the default theme for DialogFragments spawned by this DialogFragment -->
<item name="android:dialogTheme">@style/AppTheme.Dialog</item>
<!--
OPTIONAL: override the background for the dialog...i am using a dark theme,
and for some reason, there is no themes for dialogs with dark backgrounds,
so, i made my own.
-->
<item name="android:windowBackground">@drawable/dialog__window_background</item>
<!--
add the title to the dialog's theme. you can remove it later by using
DialogFragment.setStyle()
-->
<item name="android:windowNoTitle">false</item>
<item name="windowNoTitle">?android:windowNoTitle</item>
</style>
.....
</resources>
if you use a dark theme, and overrode android:windowBackground
like i did in AppTheme.Dialog
, then add a drawable/dialog__window_background.xml
file with the contents:
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetLeft="16dp"
android:insetTop="16dp"
android:insetRight="16dp"
android:insetBottom="16dp">
<shape android:shape="rectangle">
<corners android:radius="?dialogCornerRadius" />
<solid android:color="?android:colorBackground" />
</shape>
</inset>
