ExampleThe AppCompat support library provides themes to build apps with the Material Design specification. A theme with a parent of Theme.AppCompat is also required for an Activity to extend AppCompatActivity. Show
The first step is to customize your theme’s color palette
to automatically colorize your app. Instead of Theme.AppCompat, which has a dark background, you can also use Theme.AppCompat.Light or Theme.AppCompat.Light.DarkActionBar. You can customize the theme with your own colours. Good choices are in the Material design specification colour chart, and Material Palette. The "500" colours are good choices for primary (blue 500 in this example); choose "700" of the same hue for the dark one; and an a shade from a different hue as the accent colour. The primary colour is used for your app's toolbar and its entry in the overview (recent apps) screen, the darker variant to tint the status bar, and the accent colour to highlight some controls. After creating this theme, apply it to your app in the AndroidManifest.xml and also apply the theme to any particular activity. This is useful for applying a AppTheme.NoActionBar theme, which lets you implement non-default toolbar configurations. <application android:theme="@style/AppTheme" ...> <activity android:name=".MainActivity" android:theme="@style/AppTheme" /> </application>You can also apply themes to individual Views using android:theme and a ThemeOverlay theme. For example with a Toolbar: <android.support.v7.widget.Toolbar android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/colorPrimary" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />or a Button: <Button style="@style/Widget.AppCompat.Button.Colored" android:layout_width="wrap_content" android:layout_height="wrap_content" android:theme="@style/MyButtonTheme"/> <!-- res/values/themes.xml --> <style name="MyButtonTheme" parent="ThemeOverlay.AppCompat.Light"> <item name="colorAccent">@color/my_color</item> </style>You need to use a Theme.AppCompat theme (or descendant) with this activityQuestions : You need to use a Theme.AppCompat theme (or descendant) with this activity2022-08-05T01:01:02+00:00 2022-08-05T01:01:02+00:00 696 Android Studio 0.4.5 Android documentation for creating custom anycodings_android-layout dialog boxes: anycodings_android-layout http://developer.android.com/guide/topics/ui/dialogs.html If you want a custom dialog, you can instead anycodings_android-layout display an Activity as a dialog instead of anycodings_android-layout using the Dialog APIs.

Total Answers 30 29 Answers 1 : of You need to use a Theme.AppCompat theme (or descendant) with this activityThe reason you are having this problem anycodings_android-layout is because the activity you are trying anycodings_android-layout to apply the dialog theme to is anycodings_android-layout extending ActionBarActivity which anycodings_android-layout requires the AppCompat theme to be anycodings_android-layout applied. Update: Extending AppCompatActivity anycodings_android-layout would also have this problem In this case, change the Java anycodings_android-layout inheritance from ActionBarActivity to anycodings_android-layout Activity and leave the dialog theme in anycodings_android-layout the manifest as it is, a non anycodings_android-layout Theme.AppCompat value The general rule is that if you want anycodings_android-layout your code to support older versions of anycodings_android-layout Android, it should have the AppCompat anycodings_android-layout theme and the java code should extend anycodings_android-layout AppCompatActivity. If you have *an anycodings_android-layout activity that doesn't need this support, anycodings_android-layout such as you only care about the latest anycodings_android-layout versions and features of Android, you anycodings_android-layout can apply any theme to it but the java anycodings_android-layout code must extend plain old Activity. NOTE: When change from AppCompatActivity anycodings_android-layout (or a subclass, ActionBarActivity), to anycodings_android-layout Activity, must also change the various anycodings_android-layout calls with "support" to the anycodings_android-layout corresponding call without "support". anycodings_android-layout So, instead of anycodings_android-layout getSupportFragmentManager, call anycodings_android-layout getFragmentManager. 0 2022-08-05T01:01:02+00:00 2022-08-05T01:01:02+00:00Answer Link mRahman 6 Answers 2 : of You need to use a Theme.AppCompat theme (or descendant) with this activityAll you need to do is add anycodings_android-layout android:theme="@style/Theme.AppCompat.Light" anycodings_android-layout to your application tag in the anycodings_android-layout AndroidManifest.xml file. 0 2022-08-05T01:01:02+00:00 2022-08-05T01:01:02+00:00Answer Link miraj 6 Answers 3 : of You need to use a Theme.AppCompat theme (or descendant) with this activityCopying answer from @MarkKeen in the anycodings_android-layout comments above as I had the same anycodings_android-layout problem.
