我正在尝试创建一个拼图益智游戏,我想知道在不使用面具的情况下创建拼图的替代方法.目前我通过拍摄完整的图像拼图碎片,将图像分成四个部分(假设拼图是2x2),然后存储并对每个部分应用遮罩.它看起来像下面
// create standard puzzle pieces
arryPieceEndPos = new int[mCols][mRows];
arryPieceImg = new Bitmap[mCols * mRows];
arryIsPieceLocked = new boolean[mCols * mRows];
int pos = 0;
for (int c = 0; c
然后我使用辅助方法将遮罩应用于每个部分
private Bitmap maskMethod(Bitmap bmpOriginal, Bitmap bmpMask) {
// adjust mask bitmap if size is not the size of the puzzle piece
if (bmpMask.getHeight() != mPieceHeight ||
bmpMask.getWidth() != mPieceWidth) {
Log.e("TEST", "Resize Error :: H (mask): " + bmpMask.getHeight() + " // W (mask): " +
bmpMask.getWidth());
Log.d("TEST", "Resize Error :: H (norm): " + mPieceHeight + " // W (norm): " +
mPieceWidth);
}
Canvas canvas = new Canvas();
Bitmap combine = Bitmap.createBitmap(bmpOriginal.getWidth(), bmpOriginal.getHeight(), Bitmap.Config.ARGB_8888);
canvas.setBitmap(combine);
Paint paint = new Paint();
paint.setFilterBitmap(false);
canvas.drawBitmap(bmpOriginal, 0, 0, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN));
canvas.drawBitmap(bmpMask, 0, 0, paint);
paint.setXfermode(null);
return combine;
}
我看到这篇文章> http://java.dzone.com/news/connect-pictures-android用于将各个部分连接在一起,但是,这并不会在没有掩码的情况下以编程方式生成部分.任何人都可以提供如何实现这一目标的代码示例吗?我唯一的线索是我应该使用Path,但是,我仍然不确定如何.提前致谢!

拼图是一个非常复杂的视图,但是我可以帮助您了解如何使用路径。这是开发者网站的链接:http : //developer.android.com/reference/android/graphics/Path.html
查看此链接。我为您做了一件小事。您需要弄清的一件事是如何在路径上切出一个小圆圈,我不知道。我认为您必须研究剪切,才能使路径沿着一个圆(您也可以对片段外部的圆进行剪切,我之前从未做过剪切)。
private Bitmap getPuzzleBitmap(Bitmap bitmap)
{
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
calculatePuzzlePath(bitmap.getWidth(), bitmap.getHeight());
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawPath(puzzlePath, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}
private void calculatePuzzlePath(int width, int height)
{
float radius = (height / 2) - 5;
float smallRadius = radius / 3;
radius -= smallRadius * 2;
float centerX = width/2;
float centerY = height/2;
puzzlePath = new Path();
// Bottom right
puzzlePath.moveTo(centerX + radius, centerY + radius);
// Top right
puzzlePath.lineTo(centerX + radius, centerY - radius);
// Center top
puzzlePath.lineTo(centerX, centerY - radius);
// Add outside circle to center top
puzzlePath.addCircle(centerX, centerY - radius - ((radius / 3) / 2), radius / 3, Path.Direction.CCW);
// Top left
puzzlePath.lineTo(centerX - radius, centerY - radius);
// Bottom left
puzzlePath.lineTo(centerX - radius, centerY + radius);
//Bottom right
puzzlePath.lineTo(centerX + radius, centerY + radius);
}
我希望这足以开始。
祝好运!
