我加入了通过myApp共享"选项.我在接收活动类中插入了以下代码.

I have included 'share via myApp' option. I inserted following code in the receiving activity class.

检索位图图像的下一步是什么.

What is the next step to retrieve bitmap image.

推荐答案

您已经获得了Uri.现在，您必须在getBitmap()中传递该Uri以获得位图并使用该位图.

As you have already get the Uri. Now you have to pass that Uri in getBitmap() to get bitmap and use that bitmap.

Uri imageUri = intent.getData(); Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(),imageUri); Imageview my_img_view = (Imageview ) findViewById (R.id.my_img_view); my_img_view.setImageBitmap(bitmap);
