CodePudding user response：

Remove the ID from Linearlayout and add to your textview-

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    **android:id="@ id/orderItemName"** //REMOVE THIS and add to your TEXTVIEW
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:orientation="vertical"
    android:padding="1dp">

CodePudding user response：

The answer is in the error/title of this post.

Problem:

It says LinearLayout cannot be cast as TextView, which means somewhere in your code, you're trying to use and cast a LinearLayout as a TextView which is inherently wrong as a LinearLayout can't be used a TextView.

Reason:

This is the layout you've created in order_sample.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@ id/orderItemName"
   ...>
...
</LinearLayout>

You've given this LinearLayout an id named orderItemName.

But, in your Adapter's viewHolder, you're trying to set this LinearLayout to a TextView here:

TextView soldItemName;
...
soldItemName=itemView.findViewById(R.id.orderItemName);

Solution:

Remove the id orderItemName from the LinearLayout and assign it to the respective TextView.

And, your app will work.
