与其他应用共享图像 [英] Share image with other apps

问题描述

这是我的问题...我想共享一个png图片.我有可绘制的图像和资产.当我使用sharedIntent时，它可以工作，但不能达到我想要的方式.共享的文件显示为数字，没有扩展名，某些应用程序发送消息"unknow file".我能做些什么??

Here is my problem... I want to share a png image. I have the image in drawable and assets. When I use the sharingIntent it works but not in the way that I want. The file shared appears with numbers and without extension and some apps send the message "unknow file". What can i do??

这是我的代码:

    Uri uri = Uri.parse("android.resource://com.example.shareimages/" + R.drawable.caja);
    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);

    shareIntent.setType("image/png");

    shareIntent.putExtra(Intent.EXTRA_STREAM,  uri);

    startActivity(Intent.createChooser(shareIntent, "send"));

我尝试使用资产中的文件(带有此" file:///android_asset/... ")代替可绘制的文件，但没有用

I tried to use instead of drawable files, the files in assets ( with this "file:///android_asset/...) but it didn't work

推荐答案

尝试如下操作:

Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
shareIntent.setType("image/*");

// For a file in shared storage.  For data in private storage, use a ContentProvider.
Uri uri = Uri.fromFile(getFileStreamPath(pathToImage));
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(shareIntent)

如果要通过资产文件夹共享它，则必须使用ContentProvider.有关此操作的信息，请参见以下答案:

If you want to share it via the assets folder, you'll have to use a ContentProvider. See this answer on how to do so:
