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)); }
