将位图传递给另一个活动以RunTimeException结尾 [英] Passing Bitmap to Another activity ends in RunTimeException

问题描述

我正在尝试将Bitmap传递给另一个Activity，并且正在使用ImageView从另一个Activity显示相同的图像.这就是我通过位图的方式.

I am trying to pass Bitmap to another Activity, and I am displaying the same image from the other Activity using ImageView . And this is how I pass the Bitmap.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK && requestCode == CAMERA_RESULT) {

        File out = new File(getFilesDir(), "newImage.jpg");

        if(!out.exists()) {

            Toast.makeText(getBaseContext(),

                    "Error while capturing image", Toast.LENGTH_LONG)

                    .show();

            return;

        }

        Bitmap mBitmap = BitmapFactory.decodeFile(out.getAbsolutePath());

        Intent bitIntent = new Intent(this, CameraTake.class);
        bitIntent.putExtra("BitmapImage", mBitmap);
        startActivity(bitIntent);

这就是我接收值的方式:

And this is how I receive the value :

 Intent intent = getIntent();
    bitmap= (Bitmap)intent.getParcelableExtra("BitmapImage");
    ImageView im1 = (ImageView)findViewById(R.id.camOut);
    im1.setImageBitmap(bitmap);

在运行该应用程序时，这是我获得的日志:

And while running the App, here is the logcat I obtain :

在类似的问题，该解决方案建议使用图像加载库，我应该这样做，还是可以轻松解决此问题?寻找专业的答案.谢谢

In a similar question , the solution recommends to use image loading libraries, should I go for that, or can this be fixed easily? Looking for professional answers. Thanks

推荐答案

已在日志中提供了根本原因:

The root cause has been provided in the log:

由以下原因引起:android.os.TransactionTooLargeException:数据包大小 4915644字节

Caused by: android.os.TransactionTooLargeException: data parcel size 4915644 bytes

通过Intent进行数据传输的最大上限为1 MB，因此有几种传递位图的方法:

The maximum cap for data transport by Intent is 1 MB, so there are a few ways to pass a bitmap:

1. 减小位图的大小，根据您的使用情况，这可能是有效的解决方案，也可能不是有效的解决方案.
2. 将位图切碎并在接收端重新组装，您可能需要编写服务，效率并不高.做过一次，不推荐.
3. 仅传递位图的URI，然后将其重新加载到接收方的Activity上.这就是Intent要求Android相机应用拍摄照片的方式-将照片保存到存储中，仅返回存储文件的URI.
4. 如果第一个活动和第二个活动处于相同的过程中，则可以跳过以上所有内容，并将位图保存到共享的缓存中，那里有很多很多的库来完成该工作.

1. Reduce bitmap size,this may or may not be a valid solution depending on your use case.
2. Chop up the bitmap for transportation and reassembles it on the receiving end, you'll probably need to write a service for it, and it's not terribly efficient. Did it once, not recommended.
3. Only passing the URI for the bitmap, and load it anew on the receiving Activity. This is how Intent asking Android camera app to take a picture works - the picture is saved to storage and only the URI of the stored file is returned.
4. If the 1st and 2nd Activities are in the same process, you can skip all of above and save the bitmap to a shared cache, where there are many, many libraries to accomplish that.
