本文介绍了一种在Android应用中获取设备屏幕方向的方法。通过使用WindowManager来获取默认显示对象，进而得到屏幕的宽度、高度及方向。此外，还提供了解决Orientation_UNDEFINED问题的逻辑判断方法。

/* First, get the Display from the WindowManager */ Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay(); /* Now we can retrieve all display-related infos */ int width = display.getWidth(); int height = display.getHeight(); int orientation = display.getOrientation(); 或者public int getScreenOrientation() { Display getOrient = getWindowManager().getDefaultDisplay(); int orientation = getOrient.getOrientation(); // Sometimes you may get undefined orientation Value is 0 // simple logic solves the problem compare the screen // X,Y Co-ordinates and determine the Orientation in such cases if(orientation==Configuration.ORIENTATION_UNDEFINED){ Configuration config = getResources().getConfiguration(); orientation = config.orientation; if(orientation==Configuration.ORIENTATION_UNDEFINED){ //if height and widht of screen are equal then // it is square orientation if(getOrient.getWidth()==getOrient.getHeight()){ orientation = Configuration.ORIENTATION_SQUARE; }else{ //if widht is less than height than it is portrait if(getOrient.getWidth() < getOrient.getHeight()){ orientation = Configuration.ORIENTATION_PORTRAIT; }else{ // if it is not any of the above it will defineitly be landscape orientation = Configuration.ORIENTATION_LANDSCAPE; } } } } return orientation; // return value 1 is portrait and 2 is Landscape Mode }
