You need to use a Theme.AppCompat theme (or descendant) with this activity

Android Studio 0.4.5

Android documentation for creating custom dialog boxes: http://developer.android.com/guide/topics/ui/dialogs.html

If you want a custom dialog, you can instead display an Activity as a dialog instead of using the Dialog APIs. Simply create an activity and set its theme to Theme.Holo.Dialog in the <activity> manifest element:

<activity android:theme="@android:style/Theme.Holo.Dialog" >

However, when I tried this I get the following exception:

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity

I am supporting the following, and I can't using something greater than 10 for the min:

minSdkVersion 10
targetSdkVersion 19

In my styles I have the following:

<!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

And in my manifest I have this for the activity:

 <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:theme="@android:style/Theme.Holo.Light.Dialog"
            android:name="com.ssd.register.Dialog_update"
            android:label="@string/title_activity_dialog_update" >
        </activity>

Creating the dialog box like this was something I was hopping to do, as I have already completed the layout.

Can anyone tell me how I can get around this problem?

2024 Android Studio Koala

Jump to values-> themes.xml Enter this

enter image description here

<!--    <style name="Theme.FragmentExample" parent="android:Theme.Material.Light.NoActionBar" />-->

    <style name="List_Android_Sample" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

</resources>

Now on AndroidManifest.xml Update this

<activity
        android:theme="@style/List_Android_Sample"

Your activity is extending ActionBarActivty . if your activity ActionBarActivty or AppCompatActivity. Then you need to do is add android:theme="@style/Theme.AppCompat.Light" to your application tag in the AndroidManifest.xml file.

This is probably going to be an idiosyncratic answer, but the off-chance it helps someone else, say you're using a splash.xml for a splash screen:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.App.StartScreen" parent="Theme.SplashScreen">
        <item name="windowSplashScreenBackground">@color/ic_launcher_background</item>
        <item name="windowSplashScreenAnimatedIcon">@mipmap/ic_launcher</item>
        <item name="postSplashScreenTheme">@style/Theme.Assignment4</item>
        <item name="android:statusBarColor">@color/splash_screen_background</item>
    </style>
</resources>

android:statusBarColor will cause this error. I copy-pasted this from my previous assignment and my next assignment did not use a status bar.

If you're having this issue and you're instantiating a Material 3 dialog view programmatically:

Make sure not to use getApplicationContext() when requiring a Context instance, but instead use this or YourActivity.this

For example.. Instead of this

  new MaterialAlertDialogBuilder(getApplicationContext())

Use

 new MaterialAlertDialogBuilder(WHatEverActivityYouHostTheDialog.this)

Make sure your Activity is extended from AppCompactActivity

So I was using an activity which was extending from AppCompatActivity. I changed this to FragmentActivity and it worked perfectly.

I had a similar error because my activity was extending AppCompatActivity. The solution for my case was to change the base class which the activity was extending from AppCompatActivity to ComponentActivity.

I came across this issue when using SplashScreen Api, this error is also thrown when installSplashScreen() is not called in the MainActivity

override fun onCreate(savedInstanceState: Bundle?) {
        installSplashScreen()
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
}

In case the AndroidX SplashScreen library brought you here ...

This is because Theme.SplashScreen also has no R.styleable.AppCompatTheme_windowActionBar:

if (!a.hasValue(R.styleable.AppCompatTheme_windowActionBar)) {
    a.recycle();
    throw new IllegalStateException(
            "You need to use a Theme.AppCompat theme (or descendant) with this activity.");
}

This requires switching the theme to the postSplashScreenTheme, before calling super():

@Override
protected void onCreate(Bundle savedInstanceState) {

    /* When switching the theme to dark mode. */
    if (savedInstanceState != null) {
        this.setTheme(R.style.AppTheme);
    }
    super.onCreate(savedInstanceState);
    
    /* When starting the Activity. */
    if (savedInstanceState == null) {
        SplashScreen.installSplashScreen(this);
    }
}

Then the Theme.SplashScreen from AndroidManifest.xml won't interfere.


Also quite related: When using Theme.MaterialComponents, there's a bridge theme contained, which works as substitute for Theme.AppCompat: Theme.MaterialComponents.DayNight.NoActionBar.Bridge.

This Bridge theme works despite Theme.MaterialComponents not inherits from Theme.AppCompat:

<?xml version="1.0" encoding="utf-8"?>
<resources>    
    <style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar.Bridge" />   
    <style name="AppTheme.SplashScreen" parent="Theme.SplashScreen" />    
</resources>

When I was trying to add this free explorer module (NoNonsense - FilePicker) to my current App, I got this Exception:

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity

This code to add for the module to work was in a styles.xml file in a previous App, and it worked fine:

<!-- You can also inherit from NNF_BaseTheme.Light -->
<style name="FilePickerTheme" parent="NNF_BaseTheme">
    <!-- Set these to match your theme -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <!-- Setting a divider is entirely optional -->
    <item name="nnf_list_item_divider">?android:attr/listDivider</item>

    <!-- Need to set this also to style create folder dialog -->
    <item name="alertDialogTheme">@style/FilePickerAlertDialogTheme</item>

    <!-- If you want to set a specific toolbar theme, do it here -->
    <!-- <item name="nnf_toolbarTheme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item> -->
</style>

<style name="FilePickerAlertDialogTheme" parent="Theme.AppCompat.Dialog.Alert">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

But this doesn't work in a recent App. The solution was simple, I simply moved the code to the themes.xml file (and deleted it from the styles.xml file). For some reason, there's this subtle change in the modern version. Kind of obvious, but if something was working, then it normally is the correct way...

I was stuck several hours at this problem. The problem was that I implemented my own .jar dependency that didn't uses the Theme.AppCompat style in it's themes.xml and AndroidManifest.xml. Even after I changed and rebuild my dependency it didn't work. After a bit of research I found out that I should use an .aar (Android Archive) library as described here. After changing my dependency module to an Android Library I could build and implement it without errors. Hope this helps.

If someone sees this error while running Android 12 Splash screen then follow these simple steps

  1. The app theme in values/themes.xml and values-night/themes.xml should have Theme.AppCompat as the parent theme.

    <style name="Theme.Ace" parent="Theme.AppCompat.DayNight.NoActionBar">
    
  2. Use this theme in postSplashScreenTheme for the splash screen theme

    <style name="Theme.App.Starting" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">@color/orange_900</item>
    <item name="windowSplashScreenAnimatedIcon">@drawable/ic_help_outline</item>
    <item name="windowSplashScreenAnimationDuration">2000</item>
    <item name="postSplashScreenTheme">@style/Theme.Ace</item>
    
  3. Remove any theme from the starting activity and use Theme.App.Starting as an application theme

    <application...
    android:theme="@style/Theme.App.Starting">

I have faced same problem.

If you are providing context to any class or method then provide YourActivityName.this instead of getApplicationContext().

Do this

builder = new AlertDialog.Builder(YourActivity.this);

Instead of

builder = new AlertDialog.Builder(getApplicationContext());

Check if you are passing the right context to your Dialog. This happened to me and then I realized I was initiating AlertDialog.Builder with applicationContext instead of Activity context.

If you are using VCS in your project (GIT, for instance), try to:

  1. Delete your local project files;
  2. Re-import from remote.

Problem solved!

In my case, I deleted a file that contained erros, but somehow Studio was still detecting the file and therefore preventing it from building.

Hope it helps!

This really forced me to post my own answer.

Since I am using Theme.AppCompat.Light.NoActionBar, and also replaced all AlertDialog instances with support compatibility imports and still faced problems below v21 (Lollipop).

I didn't like the idea of changing the theme which was proper. So after 2 days, I finally gave some thought about the other libraries that are specifying AppTheme for their AndroidManifest.xml.

I found out that there is yet another one: Paytm Checkout SDK.

Thus, the following changes fixed the problem.

  1. Renaming AppTheme using for my app to 'XYZAppTheme'

  2. using tools:replace method in AndroidManifest of my project(app).

    <uses-permission android:name="android.permission.INTERNET" />
    
    <application
        android:name=".XYZ"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher_v2"
        android:label="@string/app_name"
        android:largeHeap="true"
        android:roundIcon="@mipmap/ic_launcher_v2_round"
        android:supportsRtl="true"
        android:theme="@style/XYZAppTheme"
        tools:replace="android:icon,android:theme">
    
        <activity
            android:name=".xyz.SplashActivity"
            android:launchMode="singleTask"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
    
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

First of all, add this as import => import androidx.appcompat.app.AlertDialog

I am posting this being the smallest ever solution to the problem. I just changed the instantiation of

new AlertDialog.Builder(mContex)

to

new AlertDialog.Builder(mContext, R.style.PreferenceDialogLight)

Where <style name="PreferenceDialogLight" parent="Base.Theme.MaterialComponents.Dialog.Alert">

If you are struggling with the Recyclerview Adapter class then use

view.getRootView().getContext()

instead of

getApplicationContext() or activity.this

for me a solution, after trying all solutions from here, was to change

    <activity
        android:name="com.github.cythara.MainActivity"
        android:label="Main">
    </activity>

to include a theme:

    <activity
        android:name="com.github.cythara.MainActivity"
        android:theme="@style/Theme.AppCompat.NoActionBar"
        android:label="Main">

If you are using the application context, like this:

final AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

change it to an activity context like this:

final AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

In my case, i was inflating a view with ApplicationContext. When you use ApplicationContext, theme/style is not applied, so although there was Theme.Appcompat in my style, it was not applied and caused this exception. More details: Theme/Style is not applied when inflater used with ApplicationContext

In Android Studio: Add support library to the gradle file and sync. Edit build.gradle(Module:app) to have dependencies as follows:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    implementation 'com.android.support:appcompat-v7:23.1.1'
    implementation 'com.android.support:design:23.1.1'
    implementation 'com.android.support:support-v4:23.1.1'
}

My support Library version is 23.1.1; use your support library version as applicable.

I was getting this same problem. Because i was creating custom navigation drawer. But i forget to mention theme in my manifest like this

android:theme="@style/Theme.AppCompat.NoActionBar"

As soon i added the above the theme to my manifest it resolved the problem.

Instead of all of this, about changing a lot of this in your app.. just do it simple as this video does.

When You're Using Kotlin, nothing solved my problem until I change the Builder parameter from 'applicationContext' to 'this'.

This Does Not Work

val dialogDelete = AlertDialog.Builder(applicationContext)
            .setTitle("Confirmation")
            .setMessage("Delete this photo?")
            .setNegativeButton(android.R.string.no){ it, which ->
                it.dismiss()
            }
dialogDelete.show()

Following Code Works

val dialogDelete = AlertDialog.Builder(this)
            .setTitle("Confirmation")
            .setMessage("Delete this photo?")
            .setNegativeButton(android.R.string.no){ it, which ->
                it.dismiss()
            }
dialogDelete.show()

In my case, I was using a style called "FullScreenTheme", and although it seemed to be correctly defined (it was a descendant of Theme.AppCompat) it was not working.

I finally realized that I was using an AAR library that internally also had defined a style called "FullScreenTheme" and it was not descendant of Theme.AppCompat. The clashing of the names was causing the problem.

Fix it by renaming my own style name so now Android is using the correct style.
