Question

Hello I am new to Android programming and I am a bit rusty with Java too since I haven’t done it in a while.
I am trying to use an example that I found online and when I try to run it with the emulator it said that my program has stopped and I have no idea why.

All that I modified was the main Java file

The code that I have is:

import android.app.Activity;
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 ScottTestActivity extends ListActivity {
/** Called when the activity is first created. */

public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.main);
    //Values to display
    String[] values = new String[] { "Android", "iPhone",                                         
    "Windows Mobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
            "Linux", "OS/2" };
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, values);
    setListAdapter(adapter);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    String item = (String) getListAdapter().getItem(position);
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
}

}

Could someone please help me? and if possible point me in a good direction that explains Android programming?

Answer 1

is this where you took your sample :

http://www.vogella.de/articles/AndroidListView/article.html

anyway as Dawid Sajdak refers, it looks that there is no listview tag in main.xml

you need to add this to res/layout/main.xml

<

ListView
  android:id="@+android:id/list"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" >
</ListView>

good luck
