Let's say that I have a ListView with some items. I want to make it so when the user clicks on an item, the app pops up a Toast containing the name of the item. For example, when the user clicks "Apple", they are presented with the toast: "You ate Apple." How can I do so?

But how to get the name of the pressed item?
you can set Item Click Listener on List View i.e.
listvw=(ListView)findViewById(R.id.listviewid);
listvw.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
Toast.makeText(ActivityName.this, "Text message", Toast.LENGTH_SHORT).show();
}
});

Same here. How to get the name of the pressed item?

You have a view of your listview item. just find the text of view i.e. ' TextView text= (TextView)view.findViewById(R.id.text_viewId); ' 'Toast.makeText(ActivityName.this, text.getText(), Toast.LENGTH_SHORT).show();'

OK thanks. I used
TextView text = (TextView) arg1.findViewById(arg1.getId()); Toast.makeText(getApplicationContext(), text.getText(), Toast.LENGTH.SHORT).show();use like that
ActivityListView .java
package com.sunil;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class ActivityListView extends ListActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Create an array of Strings, that will be put to our ListActivity
String[] namesArray = new String[] { "Linux", "Windows7", "Eclipse",
"Suse", "Ubuntu", "Solaris", "Android", "iPhone" };
/* Create an ArrayAdapter, that will actually make the Strings above
appear in the ListView */
this.setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, namesArray));
}
@Override
protected void onListItemClick(ListView l, View v,
int position, long id) {
super.onListItemClick(l, v, position, id);
// Get the item that was clicked
Object o = this.getListAdapter().getItem(position);
String keyword = o.toString();
Toast.makeText(this, "You selected: " + keyword,
Toast.LENGTH_SHORT).show();
}
}
Main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />
</LinearLayout>

I get a
java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'. Maybe let's extend the standard Activity class, not ListActivity?
Sunil Kumar
same code working in my device. Do not extends Activity and also setcontentview also . It will work fine check again
Try this code listview=(ListView)findViewById(R.id.listid);
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos,long arg3) {
// to set your list item or name
//here list is your list that you set in your adapter
list.get(pos);
}
});
