I have used some code online to parse JSON to a listview in android. Now, I want by clicking on any item on listview to send the data in the clicked row to another activity. Tried other solutions but didn't work.
What I am working on is sending a quote and its author to another activity.
public class MainActivity extends AppCompatActivity {
private String TAG = MainActivity.class.getSimpleName();
public ListView lv;
ArrayList<HashMap<String, String>> contactList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
contactList = new ArrayList<>();
lv = (ListView) findViewById(R.id.list);
new GetContacts().execute();
}
private class GetContacts extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
Toast.makeText(MainActivity.this,"Json Data is downloading",Toast.LENGTH_LONG).show();
}
@Override
protected Void doInBackground(Void... arg0) {
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String url="https://gist.githubusercontent.com/chefk5/b2a6b17037e989b902834a70cc9b4ce7/raw/667f7fe8aa74cea7e54dfb69a0d2015f7b934f0d/quotes.json";
String jsonStr = sh.makeServiceCall(url);
Log.e(TAG, "Response from url: " + jsonStr);
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
JSONArray contacts = jsonObj.getJSONArray("quotes");
// looping through All Contacts
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
String quote = c.getString("quote");
String name = c.getString("name");
// tmp hash map for single contact
HashMap<String, String> contact = new HashMap<>();
// adding each child node to HashMap key => value
contact.put("quote", quote);
contact.put("name", name);
// adding contact to contact list
contactList.add(contact);
}
} catch (final JSONException e) {
Log.e(TAG, "Json parsing error: " + e.getMessage());
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Json parsing error: " + e.getMessage(),
Toast.LENGTH_LONG).show();
}
});
}
} else {
Log.e(TAG, "Couldn't get json from server.");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Couldn't get json from server. Check LogCat for possible errors!",
Toast.LENGTH_LONG).show();
}
});
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
ListAdapter adapter = new SimpleAdapter(MainActivity.this, contactList,
R.layout.list_item, new String[]{ "quote","name"},
new int[]{R.id.email,R.id.mobile});
lv.setAdapter(adapter);
}
}
do this in onPostExecute
ListAdapter adapter = new SimpleAdapter(MainActivity.this, contactList,
R.layout.list_item, new String[]{ "quote","name"},
new int[]{R.id.email,R.id.mobile});
lv.setAdapter(adapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String quete = contactList.get(i).getQuete();
String name = contactList.get(i).getName();
Intent intent = new Intent(MainActivity.this, OtherActivity.class);
intent.putExtra("QUETE", quete);
intent.putExtra("NAME", name);
startActivity(intent);
}
});
now in your OtherActivity, put the following line of code in OnCreate() methode
String name = getIntent().getExtraString("NAME");
String quete = getIntent().getExtraString("QUETE");
thats all :)
