Question

我创建了Blank活动，然后我用这些行全屏了：

requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

但如何删除菜单？当我按下菜单按钮时，程序崩溃了。这是Manifest.xml：

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

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="18" />

    <uses-permission android:name="android.permission.VIBRATE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/gameicon"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.google.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation" >
        </activity>
        <activity
            android:name="com.example.fingercutter.MainActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.example.fingercutter.Game"
            android:label="@string/title_activity_game"
            android:screenOrientation="portrait">
        </activity>
        <activity
            android:name="com.example.fingercutter.Settings"
            android:label="@string/title_activity_settings"
            android:screenOrientation="portrait">
        </activity>
        <activity
            android:name="com.vahe_muradyan.fingercutter.About"
            android:label="@string/title_activity_about">
        </activity>
    </application>

</manifest>

我试图改变每个活动的主题，但它又崩溃了。

你在onCreateOptionsMenu上犯了错误。

@Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
