Question

我是Android初学者，不擅长英语，但让我来解释一下我的情况。

- 我想要的 -

在Chrome等网络浏览器中分享意图后，如果我按下我的应用程序。我不想移动到我的应用程序

我只想在分享意图中选择我的应用后开始一些方法。

例如，我在共享列表中按我的应用程序后。我只想显示Toast消息或调用方法。（我想留在屏幕上，不想打开我的应用程序）

如果有人知道如何做到这一点。我会很感激的。

                Bitmap bm = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);
                testImage.setImageBitmap(bm);
            } catch (Exception e) {
                e.printStackTrace();
            }

            // insert image uri to clipboard
            ClipData clip = ClipData.newRawUri("test", uri);
            ClipboardManager cm = (ClipboardManager)getActivity().getSystemService(Context.CLIPBOARD_SERVICE);
            cm.setPrimaryClip(clip);
        }

        return view;
    }
}

例如我想要附加图片中给出的CopyCopy应用程序的功能

祝你有个愉快的一天。

您应该从活动中删除setContentView。

分享意图后，留在屏幕上＆amp;不转移到选定的应用程序？
