我尝试将所选图片从活动B 返回到活动A list View，如下图所示。但有些图片无法从活动B 返回到 A ，即使我已压缩它们，我仍然可以

Answer 1

http://codepen.io/DevinGray/pen/gPxwvB用于使用Intent发送数据。如下所示：

Parcel

如果参数或返回值太大而不适合   事务缓冲区，然后调用将失败和   将抛出TransactionTooLargeException。

Binder事务缓冲区的固定大小有限，目前为1Mb ......

因此，如果我们发送byte任何大图片的数组将导致TransactionTooLargeException。

在两个应用程序组件之间发送图像是使用图像URI，图像路径，id，...而不是发送位图或字节数组。

在您的情况下，请执行以下操作：

1。使用来自活动B的意图发送selectedImage进入onActivityResult的URI到A：

更改：

   returnIntent.putExtra("photo", bytes);

为：

   returnIntent.putExtra("img_uri", selectedImage.toString());

2. 从Intent中获取img_uri作为活动A中的字符串，然后将其解析为URI。在活动A的onActivityResult方法中：

更改：

byte[] bytes = data.getByteArrayExtra("photo");

为：

Uri imgURI = Uri.parse(data.getStringExtra("img_uri"));

3。将addNewItem方法第二个参数从Bitmap更改为URI并传递imgURI：

obj.addNewItem(ReceiveType, ReceiveAmount, imgURI, ReceiveDescription);

4. 在ListView适配器中使用setImageURI为ImageView设置图像：

imageView.setImageURI(imgUri);

仍然得到E / JavaBinder：!!!失败的粘合剂交易！错误均匀图像已压缩
