@summersky14 增加范围判断即可
在IFloatWindowImpl中增加判断
/**
* 判断是否超出范围，根据自己需求设置比例大小，我自己设置的是0.025和0.975
* @param x event.getRawX()
* @param y event.getRawY()
* @return
*/
private boolean isOutOfRange(float x, float y) {
boolean b = true;
float screenWidth = Util.getScreenWidth(mB.mApplicationContext);
float screenHeight = Util.getScreenHeight(mB.mApplicationContext);
float widthRate, heightRate;
widthRate = (screenWidth - x) / screenWidth;
heightRate = (screenHeight - y) / screenHeight;
if (widthRate > 0.025 && widthRate < 0.975 && heightRate > 0.025 && heightRate < 0.975) {
b = false;
} else {
b = true;
}
return b;
}
然后在case MotionEvent.ACTION_MOVE 中判断即可
case MotionEvent.ACTION_MOVE:
if (!isOutOfRange(event.getRawX(), event.getRawY())) {
changeX = event.getRawX() - lastX;
changeY = event.getRawY() - lastY;
newX = (int) (mFloatView.getX() + changeX);
newY = (int) (mFloatView.getY() + changeY);
mFloatView.updateXY(newX, newY);
if (mB.mViewStateListener != null) {
mB.mViewStateListener.onPositionUpdate(newX, newY);
}
lastX = event.getRawX();
lastY = event.getRawY();
}
break;
