我有一个益智游戏，其中棋盘是一个矩形，边框是由一个网格单位长的棋子组成的。我有一种方法可以随机化图像并将其环绕在水平面上，但是...这确实很糟糕。它具有最奇怪的错误：根据运行的Android版本，其行为会有所不同。在2.1上，活动开始时边界没有正确对齐，但是一旦移动了一块，边界就会自动修复。不是当一块移动时，而是当移动到另一个位置时（如果我将其拖动到屏幕上并将其放回同一位置，则不会发生任何事情）。实际放下一块物体（MotionEvent.ACTION_UP）时，边界将自行校正。在2.2中，它可以正确启动，但是当我加载一个新级别（它不启动新活动但再次调用createBorder）时，它的作用方式相同。看起来是这样的：
这是我的createBorder方法：
private void createBorder(int h, int w, int levelWidthUnits, int levelHeightUnits){
//This method could definitely use some work (understatement), but it's all right for the moment.
//int blankPiece = 0;
int bored = board.getId();
int lastBorder = 0;
int borderWidth = 0;
Matrix m90 = new Matrix();
m90.setRotate(90);

m180.setRotate(180);

m270.setRotate(270);

borderWidth = (int)(bm1.getHeight()/(bm1.getWidth()/((float)(w/levelWidthUnits))));
//Log.i(TAG, "borderWidth = "+borderWidth);

Bitmap bm = BitmapFactory.decodeResource(getResources(), getRandomBorderBitmap());

}else{

}

放下一块时，它会测试是否移动。如果有，它将调用
counter.setText("Total moves: " + moves); //counter is a TextView
我认为这是导致布局自行修复的原因（也许是通过要求屏幕重新绘制自身来实现的）。我正在寻找解决我遇到的奇怪故障的方法，但是如果您对如何包装这些随机的边界部分有更好的建议，我将很高兴听到它！ （请注意：将来，我希望水平不是矩形，但仍然只有90度角）。谢谢您的帮助！这是我和发布游戏之间的最后错误！
最佳答案
我同意Gangnus在这种情况下重画所有内容。
我之所以要回答，主要是因为“如果您对如何包装这些随机的边框有更好的建议，我将很高兴听到它！”部分。这并不是说您的代码很糟糕，但您是对的，如果您想执行非矩形地图，则需要做一些工作。至少这是我的主意。
我将从布尔级别“地图”开始定义哪些是“木板”和“非木板”正方形。
在基本功能中，遍历每个图块。检查每侧是否有“活动”磁贴。如果是这样，请使用所需的位置和旋转度调用addBorder()函数。
void createBorders(int widthUnits, int heightUnits, boolean[][] activeMap) {
for(int x=0;x<widthUnits;x++) {
for(int y=0;y<heightUnits;y++) {
if(!activeMap[x][y]) // boolean "map" (true if active)
continue;
if(x == 0)
addBorder(LEFT, x, y);
else if(!activeMap[x-1][y])
addBorder(LEFT, x, y);
if(x == widthUnits-1)
addBorder(RIGHT, x, y);
else if(!activeMap[x+1][y])
addBorder(RIGHT, x, y);
if(y == 0)
addBorder(TOP, x, y);
else if(!activeMap[x][y-1])
addBorder(TOP, x, y);
if(y == heightUnits-1)
addBorder(BOTTOM, x, y);
else if(!activeMap[x][y+1])
addBorder(BOTTOM, x, y);
}
}
}
在
addBorder()函数中，获得图块的左侧和顶部位置，如左侧的(board.left + (tile.width * x))所示，与顶部相似。然后，您可以
switch(where)旋转矩阵，调整位图的大小，并根据需要从图块的基本位置调整位置。那是我无论如何都会做的事情。这样，它适用于任何基于图块的地图，即使是具有内部非活动区域的图，也无需像现在使用的那样硬编码“边缘”。
