Android屏幕属性有很多，今天学习了全屏，横屏，屏幕宽度和高度的获取。先记录下来，以后再慢慢增加。

public class FullScreenAndAttrActivity extends Activity {
    /** Called when the activity is first created. */
	TextView myTextView = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        //设置为无标题栏
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        //设置为全屏模式
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        //设置为横屏
        //setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        setContentView(R.layout.main);
        //定义DisplayMetrics对象
        DisplayMetrics myDm = new DisplayMetrics();
        //取得窗口属性
        getWindowManager().getDefaultDisplay().getMetrics(myDm);
        //窗口的宽度
        int screenWidth = myDm.widthPixels;
        //窗口的高度
        int screenHeight = myDm.heightPixels;
        myTextView = (TextView)findViewById(R.id.myTextView);
        myTextView.setText("屏幕宽度："+ screenWidth + "\n屏幕高度："+screenHeight);
    }
}
