如何在android中添加自定义选项（Dowload图像）和其他共享选项

是否可以在intent chooser中添加自定义选项（例如下载图像）和其他共享选项（如所附图像所示）

请参考以下答案：
示例代码：

不幸的是，我没有得到有用的答案。我做了一个变通办法来解决这个问题

以下是添加自定义“保存到图库”选项的代码（如附图所示）

这里的DownloadActivity是一个透明的活动，它包含下载映像的代码

public class DownloadActivity extends AppCompatActivity {

    String imageUrl;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_download);

        imageUrl = getIntent().getStringExtra("url");
        saveToGallery();
        finish();
    }


    public void saveToGallery() {
        try {
            String DIR_NAME = "Don Downloaded Images";
            String filename = "DON_IMG_" + System.currentTimeMillis();
            //String downloadUrlOfImage = "http://fun.localdon.com/DonUGCImg/DON_memes14908366211071492831321991.png";
            String downloadUrlOfImage = imageUrl;
            File direct =
                    new File(Environment
                            .getExternalStoragePublicDirectory(String.valueOf(Environment.DIRECTORY_PICTURES))
                            .getAbsolutePath() + "/" + DIR_NAME + "/");


            if (!direct.exists()) {
                direct.mkdir();
                Log.e("saveToGallery", "dir created for first time");
            }

            DownloadManager dm = (DownloadManager) DownloadActivity.this.getSystemService(Context.DOWNLOAD_SERVICE);
            Uri downloadUri = Uri.parse(downloadUrlOfImage);
            DownloadManager.Request request = new DownloadManager.Request(downloadUri);
            request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
                    .setAllowedOverRoaming(false)
                    .setTitle(filename)
                    .setMimeType("image/jpeg")
                    .setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
                    .setDestinationInExternalPublicDir(String.valueOf(Environment.DIRECTORY_PICTURES),
                            File.separator + DIR_NAME + File.separator + filename);

            dm.enqueue(request);


            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                final Intent scanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
                final Uri contentUri = Uri.fromFile(direct);
                scanIntent.setData(contentUri);
                DownloadActivity.this.sendBroadcast(scanIntent);
            } else {
                final Intent intent1 = new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + Environment.getExternalStorageDirectory()));
                DownloadActivity.this.sendBroadcast(intent1);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

如果有人有更好的方法，请分享。谢谢

@akash93谢谢分享链接，但这对我没有帮助。请提出其他建议。你看过链接了吗？它包含（更具体地说）正是你想要的need@akash93这没有帮助。我们需要在Intent Chooser中有一个下载选项。您当时还没有浏览该链接。当您使用

Intent筛选器

和

image

mime类型注册应用程序时，您的应用程序收到的回调包含可用于访问文件的图像Uri。这是clearly在我之前发布的文档链接中解释过。@SapnaSharma我没有亲自尝试过。但是你面临的问题是什么？你从哪里获得了intentList？@Adnan我没有发布完整的代码，如果你需要的话我会发布。intentList是数组列表，intent chooser添加的过滤包将显示在其中。萨普娜：好的，请发布完整的代码在这里或在我的电子邮件中分享shoutadnan@gmail.com
