Android實現動態改變屏幕方向（Landscape & Portrait）

1.AndroidManifest.xml:

<activity>
　　android:screenOrientation="portrait"

　　。。。

 

2.xx.java:

<activity>
    android:screenOrientation="portrait"
//如果是豎排,則改為橫排;反之然
if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
} else if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
