Android让全部应用都竖屏显示或者横屏显示

Android让所有应用都竖屏显示或者横屏显示

1. 所有应用竖屏显示：

?

frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java

?

?

public int rotationForOrientationLw(int orientation, int lastRotation,            boolean displayEnabled) {            // Initialize the rotation angles for each orientation once.Display d = ((WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE))                    .getDefaultDisplay();           if (d.getWidth() > d.getHeight()) {  mPortraitRotation = Surface.ROTATION_90;  mLandscapeRotation = Surface.ROTATION_0;  mUpsideDownRotation = Surface.ROTATION_270;  mSeascapeRotation = Surface.ROTATION_180;  } else {  mPortraitRotation = Surface.ROTATION_0;  mLandscapeRotation = Surface.ROTATION_90;  mUpsideDownRotation = Surface.ROTATION_180;  mSeascapeRotation = Surface.ROTATION_270;  }.......

2.??所有应用横屏屏显示：

?

frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java

?

public int rotationForOrientationLw(int orientation, int lastRotation,            boolean displayEnabled) {            // Initialize the rotation angles for each orientation once.            Display d = ((WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE))                    .getDefaultDisplay();            if (d.getWidth() > d.getHeight()) {                mPortraitRotation = Surface.ROTATION_0;  //jeff. ROTATION_90;                mLandscapeRotation = Surface.ROTATION_0;                mUpsideDownRotation = Surface.ROTATION_90;  //jeff. 270;                mSeascapeRotation = Surface.ROTATION_180;            }
