在小部件动态把一个位图时，失败的交易粘结剂 [英] Failed binder transaction when putting an bitmap dynamically in a widget

问题描述

任何人可以告诉我的失败粘结剂交易错误的原因？我可以看到logcat的此错误消息。
而试图动态把一个位图一个部件，我得到这个错误...

Can anybody tell me the reason for failed binder transaction error? I can see this error message in logcat. I am getting this error while trying to put an bitmap dynamically in a widget...

推荐答案

这是因为所有的更改RemoteViews被序列化（例如SETINT和setImageViewBitmap）引起的。位图也被序列化到内部捆绑。不幸的是这包有一个非常小的大小限制。

This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit.

您可以通过缩小图像尺寸这种方式解决这个问题：

You can solve it by scaling down the image size this way:

 public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) {

 final float densityMultiplier = context.getResources().getDisplayMetrics().density;        

 int h= (int) (newHeight*densityMultiplier);
 int w= (int) (h * photo.getWidth()/((double) photo.getHeight()));

 photo=Bitmap.createScaledBitmap(photo, w, h, true);

 return photo;
 }

选择newHeight足够小（〜100每平方应采取在屏幕上），并用它为你的小工具，你的问题就解决了​​：）

Choose newHeight to be small enough (~100 for every square it should take on the screen) and use it for your widget, and your problem will be solved :)
