我有一个使用 drawRect(Rect, Paint) 绘制的 Rect 对象。我有一个 OnTouchEvent 来检查触摸位置是否在 Rect 内。如果触摸在 Rect 内部,那么我屏幕上的某些内容会发生变化。我遇到的问题是:我必须触摸才能执行触摸语句的位置比 Rect 对象高约 50 像素。
这是我的代码的相关部分:
public class MainActivity extends Activity {
DrawView drawView;
RelativeLayout fLY;
static Rect newGame = new Rect(LEFT, 165 + 35, 320, 200 + 35);
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
fLY = new RelativeLayout(this);
drawView = new DrawView(this);
fLY.addView(drawView);
setContentView(fLY);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
int touchX = (int)event.getX();
int touchY = (int)event.getY();
switch(event.getAction()){
case MotionEvent.ACTION_DOWN:
if(newGame.contains(touchX, touchY))reset();
}
}
还有我的 DrawView 类:
public class DrawView extends View{
Paint paint = new Paint();
int COLORS[] = Constants.COLORS;
int left = 250;
int size = 35;
public DrawView(Context context) {
super(context);
}
@Override
public void onDraw(Canvas canvas) {
canvas.drawRect(MainActivity.newGame, paint);
}
}
