大家好！
我有两个片段：Fragment1和Fragment2; Fragment1包含Json，在获取Json之后，我通过.replace（..）将Fragment1替换为Fragment2并通过Bundle传输Json。
我的目标是：例如每60秒在Fragment1中刷新Json并自动更新Fragment2，但我不知道该怎么做！我需要你的帮助!!
这是我的代码： Class Fragment1
public class Fragment1 extends Fragment implements OnClickListener{
public static final String IMAGE_RESOURCE_ID="iconResourceID";
public static final String ITEM_NAME="itemName";
Button btnvalider;
//test transfer variable entre fragment
public Communicator com;
public void setCom(Communicator com) {
this.com = com;
}
/*
* Test Jsonparser
*
*/
Context c;
private ProgressDialog pDialog;
public String testfinalewa="";
JSonParser jsonParser = new JSonParser();
// url to create new product
private static String url_create_product = "http://10.0.2.2/webservice/create_personne.php";
public String getTestfinalewa() {
return testfinalewa;
}
public void setTestfinalewa(String testfinalewa) {
this.testfinalewa = testfinalewa;
}
// JSON Node names
private static final String TAG_SUCCESS = "success";
//fin test json
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
c=getActivity();
return inflater.inflate(R.layout.fragment_1, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
btnvalider=(Button)getActivity().findViewById(R.id.button1);
btnvalider.setOnClickListener(this);
this.com=(Communicator) getActivity();
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new Handler().postDelayed(new Runnable() {
public void run() {
// call JSON methods here
new AttemptLogin().execute();
}
}, 1 );
}
//interface pour transferer variable entre fragment
public interface Communicator{
public void respond(String data);
}
class AttemptLogin extends AsyncTask<String, String, String>{//<params,progress,result>
boolean failure = false;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(c);
pDialog.setMessage("Chargement...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args) {
String name ="test";// pseudo.getText().toString();
String moddepasse = "test";//mdp.getText().toString();
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", name));
Log.i("misy ve", "ok="+moddepasse);
Log.i("misy ve", "ok="+name);
params.add(new BasicNameValuePair("moddepasse", moddepasse));
Log.i("test", "mbola tena mety eto 1");
// getting JSON Object
JSONObject json = jsonParser.makeHttpRequest(url_create_product,
"POST", params);
Log.d("Create Response", json.toString());
Log.i("test", "mbola tena mety eto");
try {
int success = json.getInt(TAG_SUCCESS);
String succ=json.getString("ok");
Log.i("milay", succ);
if ((success == 1)) {
Log.i("accepter", "mdp correct");
} else {
Log.i("pas accepter", "non correct");
}
} catch (JSONException e) {
e.printStackTrace();
}
return json.toString();
}
protected void onPostExecute(String result) {
pDialog.dismiss();
com.respond(result);
Fragment2 fb=new Fragment2();
FragmentTransaction t=getFragmentManager().beginTransaction();
Bundle args=new Bundle();
args.putString("mondata", result);
fb.setArguments(args);
t.replace(R.id.myFramePrincipal, fb).commit();
}
}
}
class Fragment2
public class Fragment2 extends Fragment{
TextView text;
String aa;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
text=(TextView) getActivity().findViewById(R.id.textView1);
text.setText(getArguments().getString("mondata"));
}
public void refreshData(String data) {
aa= new String(data);
//aa.notifyDataSetChanged();
text.setText(aa);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_3, container, false);
}
public void ChangerText(String data) {
text.setText(data);
}
}
感谢您的帮助!!
