问题描述

我试图摆脱我的应用程序的每一次活动的标题栏，但它是崩溃的启动。我只修改了清单，并没有触及任何onCeate（）方法。有关清单：

I am trying to get rid of the title bar in every activity for my app, but it is crashing on startup. I only modified the manifest and did not touch any onCeate() methods. Relevant manifest:

<uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="landscape"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".UpgradeActivity"
            android:label="@string/title_activity_upgrade"
            android:screenOrientation="landscape"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        </activity>
        <activity
            android:name=".StatsActivity"
            android:label="@string/title_activity_stats"
            android:screenOrientation="landscape"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
        </activity>
        <activity
            android:name=".PrestiegeActivity"
            android:label="@string/title_activity_prestiege"
            android:screenOrientation="landscape"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        </activity>
    </application>

LogCat中：了java.lang.RuntimeException：无法启动活动ComponentInfo {} com.example.company/com.example.company.MainActivity：java.lang.IllegalStateException：你需要使用一个主题.AppCompat主题（或后代），与此活动。

- 谢谢

推荐答案

在您的styles.xml添加此

Add this in your styles.xml

<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/color_primary</item>
        <item name="colorPrimaryDark">@color/color_primary_dark</item>
        <item name="colorAccent">@color/accent_color</item>
</style>

在你的清单：

android:theme="@style/MyTheme" 

和您的活动延长AppCompatActivity

and in your activity extend AppCompatActivity
