常忘記紀錄一下
AndroidManifest.xml 設定
水平
<activity
..................................................
android:screenOrientation="landscape"

Display defaultDisplay = ((WindowManager)getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
 
int width = defaultDisplay.getWidth();
int height = defaultDisplay.getHeight();

Android模擬器取得root權限
