Question

我有一个包含许多CardView的RecyclerView。每个CardView都有一个唯一的ID。

我需要为每个CardView添加一个按钮，以便当用户点击此按钮时，他可以以＆＃34; www.domain.com/xx=ID"的格式共享一个简单的链接;通过Whatsapp或messenger或任何其他应用程序。

我尝试了以下代码：

holder.myBTN.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");
        String shareBody = "text to be shared";
        sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
        sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
        sharingIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(Intent.createChooser(sharingIntent, "Share via"));
    }
});

但是我收到以下错误：

D/ViewRootImpl: ViewPostImeInputStage ACTION_DOWN
V/FA: Inactivity, disconnecting from the service

对我来说，有一个简单的解决方案，你需要做的事情。

在Cardview的布局中，您可以添加包含Easy Share Action的工具栏： CardView toolbars

在您的RecyClerView中，每次调用onBindViewHolder时，您都可以在菜单https://developer.android.com/training/sharing/shareaction.html中指定包含所需链接和ID的项目。

如果您在使用RecyclerView和CardView时遇到问题，请按照以下指南操作：https://www.binpress.com/tutorial/android-l-recyclerview-and-cardview-tutorial/156

修改：如果您想通过WhatsApp分享，请参阅：https://www.whatsapp.com/faq/en/android/28000012或使用https://developers.facebook.com/docs/messenger/android

等API

我希望我有所帮助。：）

您通常看到的共享按钮大多数是ImageViews，并为其分配了onClick属性。如果您想添加分享按钮以分享卡片上的内容，只需在卡片布局中添加ImageView，然后在ImageView添加onClickListener并添加Intent待部署。

Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);

您还可以添加一个setType函数，可以将其设置为共享链接。

如何添加＆＃34;分享按钮＆＃34;到CardView？
