getting text of custom listview item on its click

I have a custom layout for the ListView which is as follows -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/plain" >

    <TextView
        android:id="@android:id/text1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:minHeight="?android:attr/listPreferredItemHeight"
        android:paddingLeft="6dip"
        android:textSize="16sp"
        android:textColor="#000000"
        android:paddingRight="10dip"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

When I click the item in a listview, I am getting error -

02-28 17:37:38.240: E/AndroidRuntime(20869): FATAL EXCEPTION: main 02-28 17:37:38.240: E/AndroidRuntime(20869): java.lang.ClassCastException: android.widget.LinearLayout cannot be cast to android.widget.TextView

This is because now I am using custom listview layout as above which is wrapped in a linearlayout.

The error line is-

class ListItemClickedonPaired implements OnItemClickListener
    {
        @SuppressLint("NewApi")
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,long id) {

            final String info = ((TextView) view).getText().toString(); //ERROR HERE
         }
     }

My question is-

How to get the text of the clicked item (technically a textview) when we have these as a custom items of a listview defined with above xml ?

Instead of writing a text view inside a Linear layout make the TextView as the root Tag so that the view argument in the OnItemClick() returns the reference of text view, Now you can directly typecast the view object to the TextView.


    <TextView  xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@android:id/text1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:minHeight="?android:attr/listPreferredItemHeight"
        android:paddingLeft="6dip"
        android:textSize="16sp"
        android:textColor="#000000"
        android:paddingRight="10dip"
        android:textAppearance="?android:attr/textAppearanceLarge" />

Try this :

 @Override
 public void onItemClick(AdapterView<?> parent, View view, int position,long id) {

        switch(view.getId()) {

        case R.id.text1:
            final String info = ((TextView) view).getText().toString();
           break;
        } 

     }

Try

public void onItemClick(AdapterView<?> parent, View view, int position,long id) {

        TextView tv = (TextView)view.findViewById(android.R.id.text1);
        String info = tv.getText().toString();
     }

You inflate a LinearLayout for each row. What you are doing is casting LinearLayout to TextView.

You can also use setTag and getTag

You have used a id from the android framework. So it should be android.R.id.text1 not R.id.text1 coz you have android:id="@android:id/text1". It is a mistake which i have edited.

public static final int text1
