Android: java.lang.ClassCastException: android.widget.imageView cannot be cast to android.widget.textView

I can't fix this problem on my listview template: i have the error as in the title of my post, but i won't cast imageview to textview. Here's my code:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="200dip"
android:layout_weight="1"
android:paddingBottom="10dip" >

<TextView
    android:id="@+id/mq"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:text="Metri quadri"
    android:textColor="#33b5e5"
    android:textSize="14sp"
    android:textStyle="bold" />

<TextView
    android:id="@+id/citta"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/mq"
    android:layout_alignBottom="@+id/mq"
    android:layout_centerHorizontal="true"
    android:text="Citta"
    android:textColor="#33b5e5"
    android:textSize="14sp"
    android:textStyle="bold" />

<TextView
    android:id="@+id/prezzo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:text="Prezzo"
    android:textColor="#e1e1e1"
    android:textSize="14sp"
    android:textStyle="bold" />

<TextView
    android:id="@+id/nome"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:padding="5dip"
    android:scrollHorizontally="true"
    android:singleLine="true"
    android:text="@string/testolungo"
    android:textColor="#e1e1e1"
    android:textSize="20sp"
    android:textStyle="bold" />

<ImageView
    android:id="@+id/foto"
    android:layout_width="80dip"
    android:layout_height="60dip"
    android:layout_alignParentLeft="true"
    android:layout_centerVertical="true"
    android:contentDescription="Release"
    android:padding="5dip"
    android:scaleType="centerCrop"
    android:src="@drawable/stub" />

<TextView
    android:id="@+id/descsplash"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="Small Text"
    android:textSize="16sp"
    android:textStyle="italic" />

</RelativeLayout>

The error for the java code is on line 58 of my file, where i assign the TextView id to TextView mq:

    View vi=convertView;
    if(convertView==null)
    vi = inflater.inflate(R.layout.listlay, null);
    TextView nome=(TextView)vi.findViewById(R.id.nome);
    TextView mq=(TextView)vi.findViewById(R.id.mq); // here's the error (???)
    TextView citta=(TextView)vi.findViewById(R.id.citta);
    TextView prezzo=(TextView)vi.findViewById(R.id.prezzo);
    ImageView image=(ImageView)vi.findViewById(R.id.foto);
    TextView descrizione = (TextView)vi.findViewById(R.id.descsplash);
    nome.setText(data.get(position).getNome());
    mq.setText(data.get(position).getMetriQuadri());
    citta.setText(data.get(position).getCitta());
    prezzo.setText(data.get(position).getPrezzo());
    descrizione.setText(data.get(position).getDescrizione());
    imageLoader.DisplayImage(data.get(position).getForoUrl(), image);

And here is the logcat:

Does anyone know how i can fix this problem?

Eclipse tends to mess up your resources every now and then. This leads to some odd behavior such as strings and images being swapped all over your app, and more commonly classCastException(s), which happen when Eclipse switches your Views' ids around.

A few solutions to that problem:

Clean your project.

Modify an xml layout file and save.

Delete your R file. (Don't worry it will be automatically generated again).

Basically anything that makes your project rebuild and re-generate the R file.

Just clean up your project and everything will be fine.

Some times this problem shows because we have created ImageView But Cast with Image Button as like this

 <ImageView
        android:id="@+id/iv_thumb"
        android:layout_width="50dip"
        android:layout_height="50dip"
        />

  holder.imageView = (ImageButton) convertView.findViewById(R.id.iv_thumb);

we have declared Imageview but cast to ImageButton, for this reason also have face this problem.

Initially, I was getting error:

TextView : android:id="@+id/add_expected_seekbarvalue"

SeekBar : android:id="@+id/add_expected_seekbar"

As a fix, I renamed the id for TextView as

TextView : android:id="@+id/add_expected_valueseekbar"

Even clean up and other techniques didn't work but finally renaming the id worked like a charm.

for Visual Studio Xamarin.Android Development

Like mentioned by many, Cleaning the project did the trick for me on Visual Studio For my Xamarin.Forms app, it happened after pulling in changes with new library reference.

Clean your project.

Basically anything that makes your project rebuild and re-generate the Rosource.Designer.cs file. (Burrowed from @Benito Bertoli)
