获取屏幕的宽高

获取android屏幕宽高之前的 windowManager.getDefaultDisplay().getWidth();方法已经废弃了，经过研究，发现可以通过另外一种方法获取屏幕的宽高，核心代码如下：
public class MainActivity extends AppCompatActivity {        private WindowManager windowManager;    private Point outsize;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        getSupportActionBar().hide();                //隐藏actionBar               getScreenSize();                             //拿到屏幕宽高，保存在Point里面        Toast.makeText(MainActivity.this, outsize.x+"宽", Toast.LENGTH_LONG).show();//屏幕宽度
        Toast.makeText(MainActivity.this, outsize.y+"高", Toast.LENGTH_SHORT).show();//屏幕高度

 }    private void getScreenSize() {                  //取得屏幕宽高的方法        windowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);        Display display = windowManager.getDefaultDisplay();        windowManager.getDefaultDisplay().getWidth();        outsize = new Point();        display.getSize(outsize);    }}
