Add a ListView using ListActivity

How to Add a ListView using ListActivity

1. Add a ListView to XML file.

2. Set the id to android:id="@android:id/list" in the ListView.

3. Set android:drawSelectorOnTop = "fasle" in the ListView.

4. Now open the MainActivity.java file and add the below import to the imports section.

import android.widget.ListView;
import android.app.ListActivity;

5. You will need to extend the ListActivity in your MainActivity.java file. To do this
change this:

public class MainActivity extends Activity{

to this:

public class MainActivity extends ListActivity{

6. Add the line: EditText editText between the public class and the onCreate method.
Defining the editText variable here will make this available throughout the whole class.

public class MainActivity extends Activity {

EditText editText;

    public void onCreate(Bundle savedInstanceState) {

7. Add the bolded code below in the OnCreate method after setContentView and before the end of the method }. This code will link your editText in your main.xml file to the editText in code.

          editText = (EditText) findViewById(R.id.editText);

8. Run your app to test it. It should display an EditText.

9. Set the default text for the EditText by adding to the main.xml file EditText section, anywhere between the <EditText and the /> tags.

<EditText
...
    android:text="your text here"
...
/>

10. Compile and run!
