共享图像到另一个应用程序 [英] Share images to another apps

问题描述

在我的应用程序中，我可以获取屏幕截图并将其保存到SD卡中.我想知道是否可以像图库应用程序那样将其从我的应用程序共享到Whatsapp.

In my app I can get a screen capture and save it to the sd card. I was wondering if it's possible to share it from my app to Whatsapp, for example, as the gallery app does.

在画廊中，您可以将文件共享"到Whatsapp，Facebook或Twitter.

In the gallery, you have the chance of "sharing" the file to Whatsapp, Facebook or Twitter.

我可以通过我的应用程序执行同样的操作吗?怎么样?

Can i do the same from my app? How?

谢谢！

推荐答案

是的，可以.

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
@SuppressWarnings( "deprecation" )
public static Intent shareImage(Context context, String pathToImage) {
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
        shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    else
        shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_DOCUMENT);

    shareIntent.setType("image/*");

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

因此只需添加一个共享"按钮并执行startActivity(shareIntent).

So just add a "share" button and execute startActivity(shareIntent).
