چگونگی قرار دادن اتصال به اینترنت در ترد جداگانه

درستش این هست

public class NotesActivity extends Activity {

	private ArrayList<StructTask>netTasks = new ArrayList<StructTask>();
	String result="";
	
	
	
	
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		Button btnSend=(Button)findViewById(R.id.btnSend);
		final EditText edtTitle =(EditText)findViewById(R.id.edtTitle);
		final EditText edtDesc =(EditText)findViewById(R.id.edtDesc);
		final CheckBox chkDone=(CheckBox)findViewById(R.id.chkDone);
		btnSend.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				
				
				BasicNameValuePair titlePair= new BasicNameValuePair("title",edtTitle.getText().toString());
				BasicNameValuePair descPair= new BasicNameValuePair("desc",edtDesc.getText().toString());
				
				ArrayList<NameValuePair> params=new ArrayList<NameValuePair>();
				params.add(titlePair);
				params.add(descPair);
				sendData(params);
				
				
				
				/*String title=edtTitle.getText().toString().replace(" ", "%20");
				String desc=edtDesc.getText().toString().replace(" ", "%20");
								sendData(title, desc,(byte)0);*/
							edtTitle.setText("");
							edtDesc.setText("");
								
								
				
			}
		});
		
		showData();
}
			
	
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.notes, menu);
		return true;
	}
	
	private void sendData(final ArrayList<NameValuePair>params)
	{
		
	    Thread t2=new Thread(new Runnable()
		{

			@Override
			public void run() {
				// TODO Auto-generated method stub
				result=Webservice.readUrl("http://192.168.1.3/note/insert.php",params);
			}
		  });
	     t2.start();
		}
	private void showData()
	{
		
	Thread t1=new Thread(new Runnable()
	{

		@Override
		public void run() {
			// TODO Auto-generated method stub
			result=Webservice.readUrl("http://192.168.1.3/note/webservice.php",null);
			if(result !=null )
			{
				//Log.i("LOG",result);
				try

						task.done=object.getInt("task_done")==1?true:false;
						//Log.i("LOG",object.getString("task_title"));
						netTasks.add(task);
					}
				}
				catch(JSONException e)
				{
					e.printStackTrace();
				}
			}
			for(StructTask task:netTasks )
			{
				Log.i("LOG","task ="+task.id +" "+task.Title +" "+task.desc+" "+task.done+" ");
			}
		}
	  });
	t1.start();
	}
