Android 禁止横竖屏切换

MainActivity里面的代码：

public void onConfigurationChanged(Configuration newConfig) {  
        try {  
            super.onConfigurationChanged(newConfig);  
            if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {  
                Log.v("Himi", "onConfigurationChanged_ORIENTATION_LANDSCAPE");  
            } else if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {  
                Log.v("Himi", "onConfigurationChanged_ORIENTATION_PORTRAIT");  
            }  
        } catch (Exception ex) {  
        }  
    } 

　　

 在AndroidManifest.xml里面的代码：

AndroidManifest.xml 里面加入这一行 android :screenOrientation="landscape "（landscape 是横向，portrait 是纵向）

<?xml version="1.0" encoding="utf-8"?>  
<manifest xmlns:android="http://schemas.android.com/apk/res/android"  
    package="com.himi" android:versionCode="1" android:versionName="1.0">  
    <application android:icon="@drawable/icon" android:label="@string/app_name">  
        <activity android:name=".MainActivity" android:label="@string/app_name"  
            android:screenOrientation="landscape" android:configChanges="keyboardHidden|orientation">  
            <intent-filter>  
                <action android:name="android.intent.action.MAIN" />  
                <category android:name="android.intent.category.LAUNCHER" />  
            </intent-filter>  
        </activity>  
    </application>  
    <uses-sdk android:minSdkVersion="4" />  
</manifest>
