Question

在我的程序中，我试图从图像gallary中选择图像。问题是在尝试连续两到三次选择新的imga时我得到“位图大小超过VM预算”异常

这是我的代码onActivity result

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        switch (requestCode) {
        case SELECT_IMAGE:
            String imagePath = getPath(data.getData());
            Savingimagepath(imagePath);
            img.setImageDrawable(Drawable.createFromPath(imagePath));
            break;
        }
    }
}

任何人都可以帮助解决这个问题...

这是我的原木猫......

Answer 1

您应该创建一个drawable以完全适合ImageView（img）大小。如果您打开一个大图像（如照片）并将其设置为ImageView，它需要大量内存。

只需创建一个真正具有此目标尺寸的位图

BitmapFactory.Options opts = new BitmapFactory.Options();
//The max size of any dimension (height or width) is 400 px
opts.inSampleSize = originalSize / 400;
Bitmap bmp = BitmapFactory.decodeFile(imagePath, opts);
img.setImageBitmap(bmp);
img.recycle();
