我有两个课程,一个是ReadChequeDetails.java
,另一个是SearchMain.java
in ReadChequeDetails.java
我正在检索jason数据并在列表视图中显示它们。
我需要将检索到的数据(例如:chequeNo
)传递给
在SearchMain.java
我将ReadChequeDetails.java
代码放在
package com.example.chequeinfo;
public class ReadChequeDetails extends ListActivity implements OnClickListener{
private ProgressDialog pDialog;
private static final String READ_COMMENTS_URL ="http://www.xxxx.com/abc.php";
private Button add,searchoption;
private static final String TAG_SUCCESS = "success";
private static final String TAG_POSTID = "post_id";
private static final String TAG_POSTS = "details";
private static final String TAG_CHEQUENO = "cheque_no";
private static final String TAG_BANKNAME = "bank_name";
private static final String TAG_AMOUNT = "amount";
private static final String TAG_CHEQUEDATE = "cheque_date";
private static final String TAG_CHEQUEOWNER = "cheque_owner";
private static final String TAG_SAVEDDATE = "saved_date";
private static final String TAG_SAVEDBY = "saved_by";
private JSONArray mComments = null;
private ArrayList<HashMap<String, String>> mCommentList;
ArrayList<String> newlist;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.read_cheque_details);
add = (Button)findViewById(R.id.post_details);
//search option button which take to the SearchMain.java class
searchoption=(Button)findViewById(R.id.mainsearch);
add.setOnClickListener(this);
searchoption.setOnClickListener(this);
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
new LoadComments().execute();
// loading the comments via AsyncTask
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.post_details:
Intent i = new Intent("com.example.chequeinfo.ADDCHEQUEDETAILS");
startActivity(i);
break;
case R.id.mainsearch:
Intent i1 = new Intent("com.example.chequeinfo.SEARCHMAIN");
startActivity(i1);
break;
}
}
public void updateJSONdata() {
mCommentList = new ArrayList<HashMap<String, String>>();
JSONParser jParser = new JSONParser();
JSONObject json = jParser.getJSONFromUrl(READ_COMMENTS_URL);
try {
mComments = json.getJSONArray(TAG_POSTS);
for (int i = 0; i < mComments.length(); i++) {
JSONObject c = mComments.getJSONObject(i);
String postId = c.getString(TAG_POSTID);
String chequeNo = c.getString(TAG_CHEQUENO);
String bankName = c.getString(TAG_BANKNAME);
String amount = c.getString(TAG_AMOUNT);
String chequeDate = c.getString(TAG_CHEQUEDATE);
String chequeOwner = c.getString(TAG_CHEQUEOWNER);
String savedDate = c.getString(TAG_SAVEDDATE);
String savedBy = c.getString(TAG_SAVEDBY);
//newlist is a String type array list which i need to pass into the AutocompletetextView
//which is referenced in SearchMain.java
newlist.add(chequeNo);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
public class LoadComments extends AsyncTask<Void, Void, Boolean> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(ReadChequeDetails.this);
pDialog.setMessage("Loading Details...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected Boolean doInBackground(Void... arg0) {
updateJSONdata();
return null;
}
@Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
pDialog.dismiss();
}
}
}
答案 0 :(得分:3)
看起来你应该只是意图发送它。
case R.id.mainsearch:
Intent i1 = new Intent("com.example.chequeinfo.SEARCHMAIN");
i1.putStringArrayListExtra("cheque_list", newlist);
startActivity(i1);
break;
}
然后在SearchMain.java中:
//Make this a member variable:
ArrayList<String> chequeList;
//in onCreate:
Intent i = getIntent();
chequeList = i.getStringArrayListExtra("cheque_list");
