您好我是Android新手，在我的应用中我使用Listview在json中获得了多个用户列表，并且它有一个唯一ID，如下所示。
我在我的应用中完美地获取了这些数据，现在在json我有匹配_id这个唯一现在我想根据第二页中的此ID获取用户个人资料，其json看起来像这样让我们来id=636所以我想获得详细信息..
Homefragment class
public class HomeFragment extends ListFragment {
//CustomAdapter adapter;
//private List<RowItem> rowItems;
private ProgressDialog pDialog;
//JSON parser class
JSONParser jsonParser = new JSONParser();
JSONArray matching=null;
ArrayList<HashMap<String,String>> aList;
private static String MATCH_URL = null;
private static final String TAG_MATCH="matching";
private static final String TAG_MATCH_ID="match_detail_id";
private static final String TAG_NAME="name";
private static final String TAG_PROFILE="profile_id";
private static final String TAG_IMAGE="image";
private static final String TAG_CAST="cast";
private static final String TAG_AGE="age";
private static final String TAG_LOCATION="location";
private ListView listview;
public HomeFragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String strtext = getArguments().getString("user_login_id");
MATCH_URL = "http://abcsd.com/webservice/matching?version=apps&user_login_id="+strtext;
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
aList = new ArrayList<HashMap<String,String>>();
// rowItems = new ArrayList<RowItem>();
listview=(ListView)rootView.findViewById(android.R.id.list);
new LoadAlbums().execute();
return rootView;
}
class LoadAlbums extends AsyncTask<String, String, String> {
/**
* Before starting background thread Show Progress Dialog
* */
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(HomeFragment.this.getActivity());
pDialog.setMessage("Loading...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected String doInBackground(String... args) {
ServiceHandler sh = new ServiceHandler();
// Making a request to url and getting response
String jsonStr = sh.makeServiceCall(MATCH_URL, ServiceHandler.GET);
Log.d("Response: ", "> " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
matching = jsonObj.getJSONArray(TAG_MATCH);
// looping through All Contacts
for (int i = 0; i < matching.length(); i++) {
JSONObject c = matching.getJSONObject(i);
// Storing each json item values in variable
String user_match_id=c.getString(TAG_MATCH_ID);
String user_name = c.getString(TAG_NAME);
String user_profile=c.getString(TAG_PROFILE);
String user_image=c.getString(TAG_IMAGE);
String user_cast=c.getString(TAG_CAST);
String user_age=c.getString(TAG_AGE);
String user_location=c.getString(TAG_LOCATION);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_MATCH_ID, user_match_id);
map.put(TAG_NAME,user_name);
map.put(TAG_PROFILE, user_profile);
map.put(TAG_IMAGE, user_image);
map.put(TAG_CAST, user_cast);
map.put(TAG_AGE, user_age+" years");
map.put(TAG_LOCATION, user_location);
// adding HashList to ArrayList
aList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("ServiceHandler", "Couldn't get any data from the url");
}
return null;
}
protected void onPostExecute(String file_url) {
super.onPostExecute(file_url);
// dismiss the dialog after getting all albums
if (pDialog.isShowing())
pDialog.dismiss();
// updating UI from Background Thread
/**
* Updating parsed JSON data into ListView
* */
CustomAdapter adapter = new CustomAdapter(getActivity(),aList);
setListAdapter(adapter);
}
}
}
现在在下一个活动中工作正常我希望按秒json获取完整的详细信息。
在以下活动中，我想让用户了解我应该怎么做？
public class ProfilePage extends Activity{
private ImageView cover;
private ImageView yes;
private ImageView no;
private ImageView sendmsg;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.profile_page);
cover=(ImageView)findViewById(R.id.coverimage);
yes=(ImageView)findViewById(R.id.yesbutton);
no=(ImageView)findViewById(R.id.nobutton);
sendmsg=(ImageView)findViewById(R.id.imgsendmsgg);
sendmsg.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
AlertDialog.Builder builder = new AlertDialog.Builder(ProfilePage.this);
builder.setTitle(R.string.title_alertbox_upgrade)
.setIcon(R.drawable.ic_launcher)
.setMessage(R.string.chek_upgrade)
.setCancelable(true)
.setNegativeButton(R.string.okalert_upgrade, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
});
AlertDialog welcomeAlert = builder.create();
welcomeAlert.show();
// Make the textview clickable. Must be called after show()
((TextView)welcomeAlert.findViewById(android.R.id.message)).setMovementMethod(LinkMovementMethod.getInstance());
/*// Creating alert Dialog with one Button
AlertDialog alertDialog = new AlertDialog.Builder(
ProfileEdit.this).create();
// Setting Dialog Title
alertDialog.setTitle("Edit Profile");
// Setting Dialog Message
alertDialog.setMessage("Please log on to gujjumatch.com desktop site to edit your profile " +
"and also set other details or call on 91 281 3054120");
// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.ic_launcher);
// Setting OK Button
alertDialog.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
// Write your code here to execute after dialog
// closed
Toast.makeText(getApplicationContext(),
"Thank You", Toast.LENGTH_SHORT)
.show();
}
});
// Showing Alert Message
alertDialog.show();*/
}
});
yes.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0) {
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast,
(ViewGroup) findViewById(R.id.custom_toast_layout_id));
ImageView image = (ImageView) layout.findViewById(R.id.image);
image.setImageResource(R.drawable.yes);
// set a message
TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("Interest Sent");
// Toast...
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
}
});
no.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast,
(ViewGroup) findViewById(R.id.custom_toast_layout_id));
ImageView image = (ImageView) layout.findViewById(R.id.image1);
image.setImageResource(R.drawable.no);
// set a message
TextView text = (TextView) layout.findViewById(R.id.text1);
text.setText("Interest Declined");
// Toast...
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
}
});
cover.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
// Sending image id to FullScreenActivity
Intent i = new Intent(getApplicationContext(), Fullimage.class);
// passing array index
startActivity(i);
}
});
}
}
答案 0 :(得分：0)
在列表视图的onitemclick中启动一个新的活动/片段，并在额外的位置传递“match_detail_id”。
如果您使用活动，请使用putExtra和getExtra。 如果您使用片段使用
Bundle bundle = new Bundle();
fragment.setArguments(bundle);
和
fragment.getArguments() //in oncreate of fragment.
并获取活动/片段的创建
的完整详细信息答案 1 :(得分：0)
这是片段类中的ListView。
我假设你可以轻松创建ListView ......
现在单击ListView，您需要传递这样的数据..
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
Intent intent = new Intent(getActivity(), UserBrandsFragmentDetail.class);
intent.putExtra("brand_logo", m_ArrayList.get(arg2).brand_logo);
startActivity(intent);
}
}
<强>更新
您需要拥有ListView。然后单击ListView，您需要使用我上面提到的代码...
在我上面提到的代码中，“lv”是ListView。 ：）
在您的下一个活动中，您需要使用捆绑包获取该数据......就像这样。
Bundle extra = getIntent().getExtras();
String your_data = extra.getString("your_key_while_parsing_data_through_Intent");
就是这样......你很高兴!!
要创建列表视图，您可以Google。有很多教程可供选择。
