 DisplayMetrics metrics = new DisplayMetrics();?Rect outRect = new Rect();?Timer timer = new Timer();?Display display;

public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        this.requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.main);        mainLayout = (AbsoluteLayout)this.findViewById(R.id.main_layout);        this.getWindowManager().getDefaultDisplay().getMetrics(metrics);        Log.i("smart_home", "metrics::density=" + metrics.density        		+", densityDpi="+metrics.densityDpi        		+", heightPixels="+metrics.heightPixels        		+", widthPixels="+metrics.widthPixels        		+", scaledDensity="+metrics.scaledDensity        		+", xdpi="+metrics.xdpi        		+", ydpi="+metrics.ydpi);        timer.schedule(new PrintTask(), 100, 100);    }

在AndroidManifest.xml文件中添加元素support-screens

运行程序打印出log日志
