Android学习-获取屏幕宽和高

有两种方法可以实现，看代码：

        WindowManager manager = getWindowManager();        int width = manager.getDefaultDisplay().getWidth();        int height = manager.getDefaultDisplay().getHeight();        tv = (TextView)findViewById(R.id.tv_show);        tv.setText("width="+width+",height="+height);   // 480*854

另外一种方法：

        DisplayMetrics dMetrics = new DisplayMetrics();        getWindowManager().getDefaultDisplay().getMetrics(dMetrics);        int screenWidth = dMetrics.widthPixels;        int screenHeight = dMetrics.heightPixels;        tv = (TextView)findViewById(R.id.tv_show);        tv.setText("width="+screenWidth+",height="+screenHeight);
