使用 Intent.createChooser 关闭活动

Question

我正在使用Intent.createChooser共享内容。然后共享Intent.createChooser对话框出现并且工作正常，但是当我按后退按钮关闭对话框时，它完成了活动。我想阻止Activity关闭只是想关闭Intent.createChooser对话框。onclick 事件位于Recyclerview.

 shareButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //align the selection to the
                Intent shareIntent = new Intent(Intent.ACTION_SEND);
                shareIntent.setType("text/plain");
                shareIntent.putExtra(Intent.EXTRA_TEXT, items.get(position).getShareUrl());
                context.startActivity(Intent.createChooser(shareIntent, "Share with"));
            }
        });
