java.lang.ClassCastException: android.widget.RelativeLayout

android, classcastexception, java, listview

Solution

as you are getting:

java.lang.ClassCastException: android.widget.RelativeLayout

because here:

      String product = ((TextView) view).getText().toString();

you are trying to cast ListView selected row view(RelativeLayout) to TextView. if you want to access TextView from selected row layout then do it as:

    TextView txtview = ((TextView) view.findViewById(R.id.your_textview_id));
    String product = txtview.getText().toString();

Problem

I developed a simple `listview` application and it displays the `listview` but when I'm selecting a single `listview` I get the following error. This is my single list item XML file. ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:id="@+id/product_label" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="25dip" android:textStyle="bold" android:padding="10dip" android:textColor="#ffffff"/> </LinearLayout> ``` this is my MainActivity.java file ``` import java.util.List; import android.app.ListActivity; import android.app.ProgressDialog; import android.os.Bundle; import android.widget.Toast; import android.content.Intent; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ListView; import android.widget.TextView; public class MainActivity extends ListActivity implements FetchDataListener{ private ProgressDialog dialog; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); ListView lv = getListView(); // listening to single list item on click lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // selected item String product = ((TextView) view).getText().toString(); // Launching new Activity on selecting single List Item Intent i = new Intent(getApplicationContext(), SingleListItem.class); // sending data to new activity i.putExtra("product", product); startActivity(i); } }); } private void initView() { // show progress dialog dialog = ProgressDialog.show(this, "", "Loading..."); String url = "http://pubbapp.comze.com/pubapp.php"; FetchDataTask task = new FetchDataTask(this); task.execute(url); } @Override public void onFetchComplete(List<Application> data) { // dismiss the progress dialog if(dialog != null) dialog.dismiss(); // create new adapter ApplicationAdapter adapter = new ApplicationAdapter(this, data); // set the adapter to list setListAdapter(adapter); } @Override public void onFetchFailure(String msg) { // dismiss the progress dialog if(dialog != null) dialog.dismiss(); // show failure message Toast.makeText(this, msg, Toast.LENGTH_LONG).show(); } } ``` This is my second screen java file, ``` import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.widget.TextView; public class SingleListItem extends Activity{ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(R.layout.single_list_item_view); TextView txtProduct = (TextView) findViewById(R.id.product_label); Intent i = getIntent(); // getting attached intent data String product = i.getStringExtra("product"); // displaying selected product name txtProduct.setText(product); } } ``` I have no idea how to solve this error. Can someone please help me fix this?
