Question

如果我不删除标题栏，我的应用程序将启动但是当我这样做时它会在它开始时崩溃。

这是我到目前为止的代码。

?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.v1.solitare"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">


        <activity
            android:name="com.v1.solitare.MainActivity"
            android:label="@string/app_name"
            android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
            android:screenOrientation="landscape" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

请以任何可能的方式提供帮助。我今天刚刚用Eclipse学习了Android编码，而且我很陌生。

编辑：我想我发现了LogCat错误：

Answer 1

ActionBarActivity假设您使用ActionBar，而Theme.NoTitleBar主题删除了ActionBar（因为它是新设备上标题栏的一部分而ActionBarActivity假设您是使用Theme.AppCompat主题来控制ActionBar的样式。

如果你没有动作栏可以改变你的活动以扩展FragmentActivity，尽管Android design docs是使你的应用感觉像Android应用程序的关键组件（尽管有些会说游戏有更多的回旋余地。）

应用程序在设置为Theme.NoTitleBar.Fullscreen后崩溃
