2. Base Java Class
MainActivity.java:
package com.sillycat.restclient;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import com.sillycat.restclient.rest.AllPersonActivity;
public class MainActivity extends ListActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] options = getResources().getStringArray(R.array.main_options);
ArrayAdapter arrayAdapter = new ArrayAdapter(this,
android.R.layout.simple_list_item_1, options);
setListAdapter(arrayAdapter);
}
protected void onListItemClick(ListView l, View v, int position, long id)
{
Intent intent = new Intent();
switch(position)
{
case 0:
intent.setClass(this, AllPersonActivity.class);
startActivity(intent);
break;
...snip...
default:
break;
}
}
}
MainApplication.java:
package com.sillycat.restclient;
import android.app.Application;
public class MainApplication extends Application {
...snip...
}
AsyncActivity.java:
package com.sillycat.restclient;
public interface AsyncActivity
{
public MainApplication getApplicationContext();
public void showLoadingProgressDialog();
public void showProgressDialog(CharSequence message);
public void dismissProgressDialog();
}
AbstractAsyncActivity.java:
package com.sillycat.restclient;
import android.app.Activity;
import android.app.ProgressDialog;
public abstract class AbstractAsyncActivity extends Activity implements AsyncActivity
{
protected static final String TAG = AbstractAsyncActivity.class.getSimpleName();
private ProgressDialog _progressDialog;
private boolean _destroyed = false;
@Override
public MainApplication getApplicationContext()
{
return (MainApplication) super.getApplicationContext();
}
@Override
protected void onDestroy()
{
super.onDestroy();
_destroyed = true;
}
public void showLoadingProgressDialog()
{
this.showProgressDialog("Loading. Please wait...");
}
public void showProgressDialog(CharSequence message)
{
if (_progressDialog == null)
{
_progressDialog = new ProgressDialog(this);
_progressDialog.setIndeterminate(true);
}
_progressDialog.setMessage(message);
_progressDialog.show();
}
public void dismissProgressDialog()
{
if (_progressDialog != null && !_destroyed)
{
_progressDialog.dismiss();
}
}
}
AbstractAsyncListActivity.java is almost the same:
package com.sillycat.restclient;
import android.app.Activity;
import android.app.ProgressDialog;
public abstract class AbstractAsyncActivity extends Activity implements AsyncActivity
{
protected static final String TAG = AbstractAsyncActivity.class.getSimpleName();
private ProgressDialog _progressDialog;
private boolean _destroyed = false;
@Override
public MainApplication getApplicationContext()
{
return (MainApplication) super.getApplicationContext();
}
@Override
protected void onDestroy()
{
super.onDestroy();
_destroyed = true;
}
public void showLoadingProgressDialog()
{
this.showProgressDialog("Loading. Please wait...");
}
public void showProgressDialog(CharSequence message)
{
if (_progressDialog == null)
{
_progressDialog = new ProgressDialog(this);
_progressDialog.setIndeterminate(true);
}
_progressDialog.setMessage(message);
_progressDialog.show();
}
public void dismissProgressDialog()
{
if (_progressDialog != null && !_destroyed)
{
_progressDialog.dismiss();
}
}
}
3. AllPerson Activity
AllPersonActivity.java:
package com.sillycat.restclient.rest;
import java.util.ArrayList;
import java.util.List;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import com.sillycat.easymarket.model.Person;
import com.sillycat.easymarket.view.PersonList;
import com.sillycat.restclient.AbstractAsyncListActivity;
import com.sillycat.restclient.R;
public class AllPersonActivity extends AbstractAsyncListActivity {
protected static final String TAG = AllPersonActivity.class.getSimpleName();
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
}
@Override
public void onStart()
{
super.onStart();
// when this activity starts, initiate an asynchronous HTTP GET request
new DownloadStatesTask().execute();
}
private void refreshStates(List persons)
{
if (persons == null)
{
return;
}
PersonsListAdapter adapter = new PersonsListAdapter(this, persons);
setListAdapter(adapter);
}
private class DownloadStatesTask extends AsyncTask>
{
@Override
protected void onPreExecute()
{
// before the network request begins, show a progress indicator
showLoadingProgressDialog();
}
@Override
protected List doInBackground(Void... params)
{
try
{
// The URL for making the GET request
final String url = getString(R.string.base_uri) + "/service/persons";
// Set the Accept header for "application/json"
HttpHeaders requestHeaders = new HttpHeaders();
List acceptableMediaTypes = new ArrayList();
acceptableMediaTypes.add(MediaType.APPLICATION_JSON);
requestHeaders.setAccept(acceptableMediaTypes);
// Populate the headers in an HttpEntity object to use for the request
HttpEntity requestEntity = new HttpEntity
