Android(安卓)设置全屏，画图，加载位图

设置全屏： activity中

requestWindowFeature(Window.FEATURE_NO_TITLE);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

加载位图：

Bitmap map = BitmapFactory.decodeResource(getResources(), R.drawable.chessboard);

实例：

public class GameActivity extends Activity {    public class MyView extends View    {        public MyView(Context context) {            super(context);        }        protected void onDraw(Canvas canvas) {            super.onDraw(canvas);            Bitmap map = BitmapFactory.decodeResource(getResources(), R.drawable.chessboard);            int width = canvas.getWidth();            int height = canvas.getHeight();            Paint paint = new Paint();            paint.setColor(Color.RED);            canvas.drawLine(0, 0, width - 1, height - 1, paint);            Rect rect1 = new Rect(0, 0, canvas.getWidth(), canvas.getHeight());            Rect rect2 = new Rect(0, 0, map.getWidth() / 2, map.getHeight() / 2);            canvas.drawBitmap(map, rect2, rect1, null);            invalidate();        }    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //设置全屏        requestWindowFeature(Window.FEATURE_NO_TITLE);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);          //      setContentView(R.layout.activity_game);        setContentView(new MyView(this));    }
