java.lang.IllegalStateException：软件渲染不支持硬件位图

Question

我需要获取View. 我尝试了两种方法来完成这项工作。不幸的是，两者都会导致相同的错误。

这是日志：

我仔细检查了代码，并在网上查找了相关文章。然而，我还没有解决它，这真的让我感到沮丧。这个bug只发生在android O之上。

以下是我尝试过的两种方法：

方法一：

at com.android.internal.os.ZygoteInit.null main(null)(ZygoteInit.java:870)

方法二：

public static Bitmap captureView(View view) {
    Bitmap tBitmap = Bitmap.createBitmap(
            view.getWidth(), view.getHeight(), Bitmap.Config.RGB_565);
    Canvas canvas = new Canvas(tBitmap);
    view.draw(canvas);
    canvas.setBitmap(null);
    return tBitmap;
}

需要提到的是，我已经android:hardwareAccelerated="true"为我的设置了Activity，在那里我调用了captureView方法。

您可以尝试将硬件类型位图复制到所需的类型位图，例如：

Bitmap targetBmp = originBmp.copy(Bitmap.Config.ARGB_8888, false);

Answer 2

阅读Glide hardware bitmap docs，找到PixelCopyclass，可能会解决这个bug。

使用PixelCopy转换view到Bitmap更高版本的Android O，并使用下面的Android O.以前的方法

这是我的代码：

fun captureView(view: View, window: Window, bitmapCallback: (Bitmap)->Unit) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        // Above Android O, use PixelCopy
        val bitmap = Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)
        val location = IntArray(2)
        view.getLocationInWindow(location)
        PixelCopy.request(window,
            Rect(location[0], location[1], location[0] + view.width, location[1] + view.height),
            bitmap,
            {
                if (it == PixelCopy.SUCCESS) {
                    bitmapCallback.invoke(bitmap)
                }
            },
            Handler(Looper.getMainLooper()) )
    } else {
        val tBitmap = Bitmap.createBitmap(
            view.width, view.height, Bitmap.Config.RGB_565
        )
        val canvas = Canvas(tBitmap)
        view.draw(canvas)
        canvas.setBitmap(null)
        bitmapCallback.invoke(tBitmap)
    }
}

不足之处是我必须使用回调，我不太喜欢它。

希望它有效。

如果您要转换其中包含 ImageView 的视图，并且使用 Glide 或 Coil 等图像加载库加载其图像，则必须禁用硬件位图。这些库仅将像素数据存储在图形内存中，并且最适合仅将位图绘制到屏幕上的情况。

如果你使用线圈那么你必须做这样的事情

val imageLoader = ImageLoader.Builder(context).allowHardware(false).build()
imageView.load(imageUrl, imageLoader)
