Question

Ok guys, so as an Android newbie Im working my way through various things. My issue here is Im trying to start a new intent activity in a ‘onListItemClick’. I have the method set up for this but when i run the AVD upon clicking the item in the list, nothing happens, the intent doesn’t start.

If I change the the super class to ‘ListActivity’ I get a crash message of ‘your content must have a listview whose id attribute is ‘android.r.id.list”

Can anyone tell me why the intent wont start from clicking the item in the listview?
Here’s my listview class:

package com.example.sqliteexample;



import android.app.Activity;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v4.widget.SimpleCursorAdapter;
import android.view.View;
import android.widget.ListView;
import android.widget.Toast;

public class SQLView extends ListActivity {

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    HotOrNot H = new HotOrNot(this, null, null);

    setContentView(R.layout.layout);
    ListView listContent = (ListView)findViewById(R.id.contentList);

    HotOrNot Content = new HotOrNot(this, null, null);
    Content.open();
    Cursor cursor = Content.getData();

    startManagingCursor(cursor);

    @SuppressWarnings("static-access")
    String [] from = new String [] {H.KEY_NAME, H.KEY_HOTNESS};
    int [] to = new int [] {R.id.txtName, R.id.txtAge};

    @SuppressWarnings("deprecation")
    SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.entries, cursor, from, to);

    listContent.setAdapter(cursorAdapter);
 }


public void onListItemClick(ListView l, View v, int posistion, long id)
{

    Intent i = new Intent("com.example.sqliteexample.SQLiteExample");

    startActivity(i);
}




}

if you’re gonna use a ListActivity then you don’t need this line:

ListView listContent = (ListView)findViewById(R.id.contentList);

BUT that specific ListView being referred to right now (provided it’s in the corresponding xml layout) must have it’s id changed to

<ListView
  android:id="@android:id/list"
