Cannot use android:Theme.Material in AppCompatActivity

Question

First, I created two styles, one is value and the other is value-21.

In values/styles.xml is

<resources>
    <style name="AppTheme" parent="Theme.AppCompat"></style>
</resources>

In values-v21/styles.xml is

<resources>
    <style name="AppTheme" parent="android:Theme.Material"></style>
</resources>

My gradle file (app.gradle)

Since the ActionBarActivity is deprecated, so I use AppCompatActivity.

When I set these two style values and extend AppCompatActivity in MainActivity, I got the exception:

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

I do the two different changes and that exception never shows up again:

• Extend "android.app.Activity" instead of v7.AppCompatActivity.
• Change to "Theme.AppCompat" in values-v21/styles.xml.

Should I extend the "android.app.Activity" if I want to use the design theme?

Or, is there another way to use material design theme?

Thanks.

Replace Below Theme in your styles.xml File.

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

    <style name="MyMaterialTheme" parent="MyMaterialTheme.Base">
        <item name="android:windowContentTransitions">true</item>
        <item name="android:windowAllowEnterTransitionOverlap">true</item>
        <item name="android:windowAllowReturnTransitionOverlap">true</item>
    </style>

    <style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
</resources>

And use extends AppCompatActivity in your MainActivity.

And Finally use this Theme in Manifestfile.

   <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/MyMaterialTheme">
    </application>

Gradle File dependencies.

    dependencies 
        {
         compile fileTree(dir: 'libs', include: ['*.jar']) compile 

'com.android.support:appcompat-v7:23.3.0' compile 

'com.android.support:recyclerview-v7:23.1.1' compile 

'com.android.support:cardview-v7:23.2.1' // For NavigationView Using Menu 

'compile 'com.android.support:design:23.3.0' // For Google Map compile 

'com.google.android.gms:play-services-maps:9.8.0' 
      } 

Edit my theme as you want. Hope it will Helps...

Try this style.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>

    <style name="MyRadioButton" parent="Theme.AppCompat.Light">
        <item name="colorControlNormal">@color/colorRadioon</item>
        <item name="colorControlActivated">@color/colorRadioof</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

style.xml(v 21)

<resources>>
    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

update Your Gradle File using below code

add aaptOption in your gradle

aaptOptions {
        additionalParameters "--no-version-vectors"
    }

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"


    defaultConfig {
        applicationId "com.jmtechnologies.askuscash"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        javaMaxHeapSize "2g"
    }

    // important to run code on kitkat

    aaptOptions {
        additionalParameters "--no-version-vectors"
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    // multidex
    compile 'com.android.support:multidex:1.0.0'


    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.support:design:25.1.0'
    compile 'com.android.support:recyclerview-v7:25.1.0'



}

Write the below theme in your style.xml file.

<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">any_color_code</item>
    <item name="colorPrimaryDark">any_color_codek</item>
    <item name="colorAccent">any_color_code</item>
</style>

and write extends AppCompatActivity in your `MainActivity

and in the Manifest.xml file write your application tag as below:

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppBaseTheme">
</application>
