将主题更改为noTitle时,应用程序崩溃

标签: android android-theme

我有一个小应用程序,我有一个标题栏。我想摆脱它,并读到我应该将清单中的主题更改为@android:style/Theme.NoTitleBar.Fullscreen。 (那是@style/AppTheme

我必须从系统资源中浏览noTitle主题并添加它。

现在,如果我启动该应用程序,它会说它不幸地停止了工作#。

我的清单:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.esrmdesign"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

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

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

activity_main.xml中:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.esrmdesign.MainActivity"
    tools:ignore="MergeRootFrame" />

logcat的:

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

当您使用appcompatActionBar而未在清单文件中设置兼容主题时,会抛出此异常。兼容的主题可以是例如

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

如果您使用appcompat库来支持API 7或更高版本的ActionBar,则需要跟踪以下信息,

1.始终使用最新的appcompat库。

2.不要忘记根据需要添加如下所示的兼容主题。    e.g:

android:theme="@style/Theme.AppCompat.Light"
android:theme="@style/Theme.AppCompat.Light.DarkActionBar"

3.不要在Java文件中使用requestWindowFeature(Window.FEATURE_NO_TITLE);,即不要隐藏TitleBar。因为ActionBar取代了它。

答案 1 :(得分:0)

您似乎试图在ActionBar中使用Activity,这是您获得IllegalStateException的原因。

按照android:theme="@style/ThemeAppCompat.Light" stacktrace

中的建议将主题更改为Exception
