Android 获取物理屏幕宽和高

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        DisplayMetrics metrics = new DisplayMetrics();
        Display display = MainActivity.this.getWindowManager().getDefaultDisplay();
        display.getRealMetrics(metrics);
        int width = metrics.widthPixels;
        int height = metrics.heightPixels;
        Log.e("-------width", String.valueOf(width));
        Log.e("-------height", String.valueOf(height));
    }
}
