How to get table values from a MySQL database and show it in Android as Tables.?

Here we are accessing a mysql database and get the table values and show it in the Android side as tables.

These are some tutorials that I have posted on connection with php and getting tablevalues.
1. Android phpmySQL connection redone.

2. Simplest Lazy Loading ListView Example in Android with data populated from a MySQL database using php.

Here we have 3 classes
1. GetDataFromDB.java – Gets value from DB in the form of JSON.
2. Users.java _ Class which holds the one row table object.
3. MainActivity.java _ Which implements these classes and show the tables.

MainActivity.java

import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TableRow.LayoutParams;
import android.widget.TextView;

public class MainActivity extends Activity {

	String data = "";
	TableLayout tl;
	TableRow tr;
	TextView label;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		tl = (TableLayout) findViewById(R.id.maintable);

		final GetDataFromDB getdb = new GetDataFromDB();
		new Thread(new Runnable() {
			public void run() {
				data = getdb.getDataFromDB();
				System.out.println(data);
				
				runOnUiThread(new Runnable() {
					
					@Override
					public void run() {
						ArrayList<Users> users = parseJSON(data);
						addData(users);						
					}
				});
				
			}
		}).start();
	}

	public ArrayList<Users> parseJSON(String result) {
		ArrayList<Users> users = new ArrayList<Users>();
		try {
			JSONArray jArray = new JSONArray(result);
			for (int i = 0; i < jArray.length(); i++) {
				JSONObject json_data = jArray.getJSONObject(i);
				Users user = new Users();
				user.setId(json_data.getInt("id"));
				user.setName(json_data.getString("name"));
				user.setPlace(json_data.getString("place"));
				users.add(user);
			}
		} catch (JSONException e) {
			Log.e("log_tag", "Error parsing data " + e.toString());  
		}
		return users;
	}

The activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ScrollView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:fillViewport="true"
    android:    scrollbars  =  "none"
    android:layout_below="@+id/textView1">
        <TableLayout
            android:layout_width="wrap_content"
            android:layout_height="0dp"
            android:stretchColumns="1,0,0"
            android:id="@+id/maintable" >
        </TableLayout>
    </ScrollView>
    
</RelativeLayout>

The server Side php.

GetUsers.php

<?php

	mysql_connect("localhost","root",""); // host, username, password...
	mysql_select_db("testdb"); // db name...
	 
	$q=mysql_query("SELECT * FROM users");
	while($row=mysql_fetch_assoc($q))
			$json_output[]=$row;
	 
	print(json_encode($json_output));
	 
	mysql_close();
	
?>
