This article shows to create ListActivity & BaseAdapter in Android.

1- Create BaseAdapter for ListActivity(MyAdapter.java).

import android.app.Activity;

import android.view.View;

import android.view.ViewGroup;

import android.widget.BaseAdapter;

import android.widget.TextView;

public class MyAdapter extends BaseAdapter {

private Activity activity;

private String[] str;

public MyAdapter(Activity c, String[] str)

{

this.activity = c;

this.str = str;

}

@Override

public int getCount() {

// TODO Auto-generated method stub

return (str.length);

}

@Override

public Object getItem(int arg0) {

// TODO Auto-generated method stub

return str[arg0];

}

@Override

public long getItemId(int arg0) {

// TODO Auto-generated method stub

return arg0;

}

@Override

public View getView(int arg0, View arg1, ViewGroup arg2) {

// TODO Auto-generated method stub

TextView txtView;

if(arg1 == null)

{

        txtView= new TextView(activity);

txtView.setPadding(15,15,15,15);

}

else

txtView= (TextView) arg1;

txtView.setText(str[arg0].toString());

txtView.setTextSize(20);

return txtView;

}

}

2- Create ListActivity(MainActivity.java).

import android.app.ListActivity;

import android.os.Bundle;

public class MainActivity extends ListActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setListAdapter(new MyAdapter(this, new String[]{"Android", "PHP", "ASP.NET", "iPhone"}));

}

}
