Question

int currentOrientation = getResources().getConfiguration().orientation;
        if (currentOrientation == Configuration.ORIENTATION_PORTRAIT) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        } else if(currentOrientation == Configuration.ORIENTATION_LANDSCAPE){
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        }

这是用于以编程方式锁定屏幕方向的代码。但它不适用于反向纵向和反向横向。可能是什么解决方案。

Answer 1

以下是在private int getScreenOrientation() { int rotation = getWindowManager().getDefaultDisplay().getRotation(); DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); int width = dm.widthPixels; int height = dm.heightPixels; int orientation; // if the device's natural orientation is portrait: if ((rotation == Surface.ROTATION_0 || rotation == Surface.ROTATION_180) && height > width || (rotation == Surface.ROTATION_90 || rotation == Surface.ROTATION_270) && width > height) { switch(rotation) { case Surface.ROTATION_0: orientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT; break; case Surface.ROTATION_90: orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE; break; case Surface.ROTATION_180: orientation = ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT; break; case Surface.ROTATION_270: orientation = ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE; break; default: Log.e(TAG, "Unknown screen orientation. Defaulting to " + "portrait."); orientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT; break; } } // if the device's natural orientation is landscape or if the device // is square: else { switch(rotation) { case Surface.ROTATION_0: orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE; break; case Surface.ROTATION_90: orientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT; break; case Surface.ROTATION_180: orientation = ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE; break; case Surface.ROTATION_270: orientation = ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT; break; default: Log.e(TAG, "Unknown screen orientation. Defaulting to " + "landscape."); orientation = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE; break; } } return orientation; } class

的常量中获取当前方向的代码

setRequestedOrientation(getScreenOrientation());
