再生位异常 [英] Recycled bitmap exception

问题描述

我得到这个异​​常：

例外：java.lang.IllegalStateException：无法复制一个循环位图

Exception: java.lang.IllegalStateException: Can't copy a recycled bitmap

我的code是：

    int width = bitmap.getWidth();
    int height = bitmap.getHeight();
    int newWidth;
    int newHeight;
    if (width >= height) {
        newWidth = Math.min(width,1024);
        newHeight = (int) (((float)newWidth)*height/width);
    }
    else {
        newHeight = Math.min(height, 1024);
        newWidth = (int) (((float)newHeight)*width/height);
    }
    float scaleWidth = ((float)newWidth)/width;
    float scaleHeight = ((float)newHeight)/height;

    Matrix matrix = new Matrix();
    matrix.postScale(scaleWidth, scaleHeight);
    switch (orientation) {
    case 3:
        matrix.postRotate(180);
        break;
    case 6:
        matrix.postRotate(90);
        break;
    case 8:
        matrix.postRotate(270);
        break;
    }
    Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);
    bitmap.recycle();
    try {
        bitmap = resizedBitmap.copy(resizedBitmap.getConfig(), true);
    }
    catch (Exception e) {
        Log.v(TAG,"Exception: "+e);
    }

如果该异常是告诉我，我已经回收的 resizedBitmap 的，这显然是错误的！我在做什么错了？

If the exception is telling me that I've recycled resizedBitmap, that is patently false! What am I doing wrong??

推荐答案

您实际上是调用 bitmap.recycle（）; 这行之后：

You are actually calling bitmap.recycle(); after this line:

Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);
