How to show data JSON in Listview Android based on the same key JSON [duplicate]

I am new to android and java.Recently I am having problem with displaying fetched json data into listview using baseadapter.
At first I have used this code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new TheTask().execute();
}
class TheTask extends AsyncTask<Void,Void,String>
{
#Override
protected String doInBackground(Void... params) {
String str = null;
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
String response = result.toString();
try {
ArrayList<String> stringArray = new ArrayList<String>();
JSONArray new_array = new JSONArray(response);
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
stringArray.add(jsonObject.getString("title").toString());
}
catch (JSONException e) {
e.printStackTrace();
}
}
ArrayAdapter<String> adapter = new ArrayAdapter<String> (MainActivity.this,R.layout.test_tuh,stringArray);
ListView list= (ListView) findViewById(R.id.listView1);
list.setAdapter(adapter);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//tv.setText("error2");
}
}
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
This code displays fetched json data sucessfully. But it only displays only one row. I need more than one (two) rows in listview. So I have tried this code
and it does not work, it shows a blank screen .
My code is below,
class TheTask extends AsyncTask<Void,Void,String>
{
#Override
protected String doInBackground(Void... params) {
String str = null;
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
String response = result.toString();
try {
arrayList=new ArrayList<get_set>();
ArrayList<String> stringArray = new ArrayList<String>();
JSONArray new_array = new JSONArray(response);
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
stringArray.add(jsonObject.getString("title").toString());
}
catch (JSONException e) {
e.printStackTrace();
}
}
ListView listView;
adap= new BaseAdapter() {
LayoutInflater inflater=(LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
#Override
public View getView(int position, View view, ViewGroup viewgroup) {
if (view==null) {
view=inflater.inflate(R.layout.bsdi, null);
}
TextView title_tuh=(TextView) view.findViewById(R.id.title1);
TextView notice_tuh=(TextView) view.findViewById(R.id.notice1);
title_tuh.setText(arrayList.get(position).getTitle());
notice_tuh=.setText(arrayList.get(position).getNotice());
return view;
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return arrayList.get(position);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return arrayList.size();
}
};
listView=(ListView) findViewById(R.id.listView1);
listView.setAdapter(adap);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//tv.setText("error2");
}
}
As far I am realizing that , the problem is here
ArrayList<String> stringArray = new ArrayList<String>();
JSONArray new_array = new JSONArray(response);
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
stringArray.add(jsonObject.getString("title").toString());
}
catch (JSONException e) {
e.printStackTrace();
}
}
As far I am guesing that extracted json data is storing in stringArray but its not used later. If I try to use it like this , then I get error
title_tuh.setText(stringArray .get(position).getTitle());
notice_tuh=.setText(stringArray .get(position).getNotice());
If I try to not to use
ArrayList stringArray = new ArrayList();
and use
arrayList=new ArrayList(); instead , like this then I also get error.
arrayList=new ArrayList<get_set>();
JSONArray new_array = new JSONArray(response);
//JSONArray jsonArray = new JSONArray();
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
arrayList.add(jsonObject.getString("title").toString());
// String in = mInflater.inflate(R.layout.custom_row_view, null);
}
catch (JSONException e) {
e.printStackTrace();
}
}
I can not finding out how to solve this problem.I have seen many online tutorials but those was not helpful for me. Please help me.

First u need t create row_listitem.xml file like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="80dp"
android:background="#drawable/list_selector"
android:orientation="vertical"
android:padding="5dp" >
<ImageView
android:id="#+id/iv_icon_social"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_centerVertical="true"
android:background="#drawable/image_border"
android:src="#drawable/sms_t"
android:visibility="gone" />
<LinearLayout
android:id="#+id/thumbnail"
android:layout_width="fill_parent"
android:layout_height="85dp"
android:layout_marginRight="50dp"
android:layout_marginTop="0dp"
android:layout_toRightOf="#+id/iv_icon_social"
android:gravity="center_vertical"
android:orientation="vertical"
android:padding="5dip"
android:visibility="visible" >
<TextView
android:id="#+id/txt_ttlsm_row"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:text="Sample text"
android:textSize="18dp"
android:textStyle="bold" />
<TextView
android:id="#+id/txt_ttlcontact_row2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="0dp"
android:layout_marginTop="3dp"
android:paddingLeft="10dp"
android:maxEms="20"
android:maxLines="2"
android:singleLine="false"
android:ellipsize="end"
android:text="Sample text2"
android:textColor="#808080"
android:textSize="15dp"
android:textStyle="normal"
android:visibility="visible" />
</LinearLayout>
</RelativeLayout>
Now, u need to create Custom BaseAdapter like:
public class BaseAdapter2 extends BaseAdapter {
private Activity activity;
// private ArrayList<HashMap<String, String>> data;
private static ArrayList title,notice;
private static LayoutInflater inflater = null;
public BaseAdapter2(Activity a, ArrayList b, ArrayList bod) {
activity = a;
this.title = b;
this.notice=bod;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return title.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.row_listitem, null);
TextView title2 = (TextView) vi.findViewById(R.id.txt_ttlsm_row); // title
String song = title.get(position).toString();
title2.setText(song);
TextView title22 = (TextView) vi.findViewById(R.id.txt_ttlcontact_row2); // notice
String song2 = notice.get(position).toString();
title22.setText(song2);
return vi;
}
}
Now, u can set up your main activity like:
public class MainActivity extends Activity {
ArrayList<String> title_array = new ArrayList<String>();
ArrayList<String> notice_array = new ArrayList<String>();
ListView list;
BaseAdapter2 adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = (ListView) findViewById(R.id.listView1);
new TheTask().execute();
}
class TheTask extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... params) {
String str = null;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
String response = result.toString();
try {
JSONArray new_array = new JSONArray(response);
for (int i = 0, count = new_array.length(); i < count; i++) {
try {
JSONObject jsonObject = new_array.getJSONObject(i);
title_array.add(jsonObject.getString("title").toString());
notice_array.add(jsonObject.getString("notice").toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter = new BaseAdapter2(MainActivity.this, title_array, notice_array);
list.setAdapter(adapter);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
// tv.setText("error2");
}
}
}
}

#Allen Chun , actually its not in my mind currently that what I have changed in my code to run my code perfectly. But I am sharing all my codes which are working perfectly.
Its my layout code,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/fsr"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Notice Board"
android:textSize="20px" />
<TextView
android:id="#+id/err_msg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""
android:gravity="center" />
<ListView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/list_notice2"
android:layout_gravity="center" />
</LinearLayout>
This is my custom listview layout codes,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:paddingTop="10dp"
android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
/>
<TextView
android:id="#+id/notice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Small Text"
android:paddingTop="5dp"
android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
its my activity named "NoticeBoard" .
public class NoticeBoard extends Activity {
ArrayList<String> title_array = new ArrayList<String>();
ArrayList<String> notice_array = new ArrayList<String>();
ListView list;
base_adapter3 adapter;
TextView f,msg;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_notice);
list = (ListView) findViewById(R.id.list_notice2);
msg=(TextView) findViewById(R.id.err_msg);
new test_ays().execute();
}
class test_ays extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... params) {
String str = null ;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if(result!=null) // add this
{
String response = result.toString();
try {
JSONArray new_array = new JSONArray(response);
for (int i = 0, count = new_array.length(); i < count; i++) {
try {
JSONObject jsonObject = new_array.getJSONObject(i);
title_array.add(jsonObject.getString("title").toString());
notice_array.add(jsonObject.getString("notice").toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter = new base_adapter3(NoticeBoard.this, title_array, notice_array);
list.setAdapter(adapter);
// f=(TextView) findViewById(R.id.textTuh);
// f.setText(title_array);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
// tv.setText("error2");
}
}
else{
msg.setText("You need a working data connection...");
}
}
}
}
And its my custom baseadapter codes,
public class base_adapter2 extends BaseAdapter {
private Activity activity;
//private ArrayList<HashMap<String, String>> data;
private static ArrayList title,notice;
private static LayoutInflater inflater = null;
public base_adapter2(Activity a, ArrayList b) {
activity = a;
this.title = b;
// this.notice=bod;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return title.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.bsdi_adapter, null);
TextView title2 = (TextView) vi.findViewById(R.id.txt1); // title
String song = title.get(position).toString();
title2.setText(song);
return vi;
}
}

In this example, I am connecting to Twitters public timeline JSON url.

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class HomeActivity extends ListActivity {
/** Called when the activity is first created. */
#SuppressWarnings({ "rawtypes", "unchecked" })
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, this.fetchTwitterPublicTimeline()));
}
public ArrayList<String> fetchTwitterPublicTimeline()
{
ArrayList<String> listItems = new ArrayList<String>();
try {
URL twitter = new URL(
"http://twitter.com/statuses/public_timeline.json");
URLConnection tc = twitter.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
tc.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
JSONArray ja = new JSONArray(line);
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = (JSONObject) ja.get(i);
listItems.add(jo.getString("text"));
}
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return listItems;
}
}
Please direct your attention on the listItems.add(jo.getString(“text”)); line. This is the part that I am grabbing a “text” attribute/property of single JSON object. To get a more “visual” picture of all available attributes/properties you might want to take a look at the XML version of twitters public timeline. This way you will get nice colored XML in your browser, where you can see all available attributes.

ListView from JSON data fetched using Retrofit2 service
JSON response
{
"results": [
{
"phone": "+9178XXXX66",
"name": "Olivia"
},
{
"phone": "+9178XXXX66",
"name": "Isla"
},
{
"phone": "+9178XXXX66",
"name": "Emily"
},
{
"phone": "+9178XXXX66",
"name": "Amelia"
},
{
"phone": "+9178XXXX66",
"name": "Sophia"
}],
"statusCode": "1",
"count": "2"
}
In MainActivity.java we will pass JSON data as ArrayList(dummyData)
customListAdapter = new CustomListAdapter(getApplicationContext(), dummyData);
listView = (ListView) findViewById(R.id.listShowJSONData);
listView.setAdapter(customListAdapter);
In custom BaseAdapter our
...
...
#Override
public MyModel getItem(int i) {
return this.users.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
#Override
public View getView(final int i, View view, ViewGroup viewGroup) {
if(view==null)
{
view= LayoutInflater.from(c).inflate(R.layout.json_data_list,viewGroup,false);
}
TextView mUserDetails = (TextView) view.findViewById(R.id.userDetails);
TextView mUserStatus = (TextView) view.findViewById(R.id.userStatus);
Object getrow = this.users.get(i);
LinkedTreeMap<Object,Object> rowmap = (LinkedTreeMap) getrow;
String name = rowmap.get("name").toString();
String phone = rowmap.get("phone").toString();
mUserDetails.setText(name);
mUserStatus.setText(phone);
return view;
}
...
...
Here MyModel will be used as custom mapping model of response we will get from service

How can i parse JSON from URL on Android and display it in listview [duplicate]

I am new to android and java.Recently I am having problem with displaying fetched json data into listview using baseadapter.
At first I have used this code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new TheTask().execute();
}
class TheTask extends AsyncTask<Void,Void,String>
{
#Override
protected String doInBackground(Void... params) {
String str = null;
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
String response = result.toString();
try {
ArrayList<String> stringArray = new ArrayList<String>();
JSONArray new_array = new JSONArray(response);
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
stringArray.add(jsonObject.getString("title").toString());
}
catch (JSONException e) {
e.printStackTrace();
}
}
ArrayAdapter<String> adapter = new ArrayAdapter<String> (MainActivity.this,R.layout.test_tuh,stringArray);
ListView list= (ListView) findViewById(R.id.listView1);
list.setAdapter(adapter);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//tv.setText("error2");
}
}
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
This code displays fetched json data sucessfully. But it only displays only one row. I need more than one (two) rows in listview. So I have tried this code
and it does not work, it shows a blank screen .
My code is below,
class TheTask extends AsyncTask<Void,Void,String>
{
#Override
protected String doInBackground(Void... params) {
String str = null;
try
{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
String response = result.toString();
try {
arrayList=new ArrayList<get_set>();
ArrayList<String> stringArray = new ArrayList<String>();
JSONArray new_array = new JSONArray(response);
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
stringArray.add(jsonObject.getString("title").toString());
}
catch (JSONException e) {
e.printStackTrace();
}
}
ListView listView;
adap= new BaseAdapter() {
LayoutInflater inflater=(LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
#Override
public View getView(int position, View view, ViewGroup viewgroup) {
if (view==null) {
view=inflater.inflate(R.layout.bsdi, null);
}
TextView title_tuh=(TextView) view.findViewById(R.id.title1);
TextView notice_tuh=(TextView) view.findViewById(R.id.notice1);
title_tuh.setText(arrayList.get(position).getTitle());
notice_tuh=.setText(arrayList.get(position).getNotice());
return view;
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return arrayList.get(position);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return arrayList.size();
}
};
listView=(ListView) findViewById(R.id.listView1);
listView.setAdapter(adap);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
//tv.setText("error2");
}
}
As far I am realizing that , the problem is here
ArrayList<String> stringArray = new ArrayList<String>();
JSONArray new_array = new JSONArray(response);
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
stringArray.add(jsonObject.getString("title").toString());
}
catch (JSONException e) {
e.printStackTrace();
}
}
As far I am guesing that extracted json data is storing in stringArray but its not used later. If I try to use it like this , then I get error
title_tuh.setText(stringArray .get(position).getTitle());
notice_tuh=.setText(stringArray .get(position).getNotice());
If I try to not to use
ArrayList stringArray = new ArrayList();
and use
arrayList=new ArrayList(); instead , like this then I also get error.
arrayList=new ArrayList<get_set>();
JSONArray new_array = new JSONArray(response);
//JSONArray jsonArray = new JSONArray();
for(int i = 0, count = new_array.length(); i< count; i++)
{
try {
JSONObject jsonObject = new_array.getJSONObject(i);
arrayList.add(jsonObject.getString("title").toString());
// String in = mInflater.inflate(R.layout.custom_row_view, null);
}
catch (JSONException e) {
e.printStackTrace();
}
}
I can not finding out how to solve this problem.I have seen many online tutorials but those was not helpful for me. Please help me.

First u need t create row_listitem.xml file like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="80dp"
android:background="#drawable/list_selector"
android:orientation="vertical"
android:padding="5dp" >
<ImageView
android:id="#+id/iv_icon_social"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_centerVertical="true"
android:background="#drawable/image_border"
android:src="#drawable/sms_t"
android:visibility="gone" />
<LinearLayout
android:id="#+id/thumbnail"
android:layout_width="fill_parent"
android:layout_height="85dp"
android:layout_marginRight="50dp"
android:layout_marginTop="0dp"
android:layout_toRightOf="#+id/iv_icon_social"
android:gravity="center_vertical"
android:orientation="vertical"
android:padding="5dip"
android:visibility="visible" >
<TextView
android:id="#+id/txt_ttlsm_row"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:text="Sample text"
android:textSize="18dp"
android:textStyle="bold" />
<TextView
android:id="#+id/txt_ttlcontact_row2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="0dp"
android:layout_marginTop="3dp"
android:paddingLeft="10dp"
android:maxEms="20"
android:maxLines="2"
android:singleLine="false"
android:ellipsize="end"
android:text="Sample text2"
android:textColor="#808080"
android:textSize="15dp"
android:textStyle="normal"
android:visibility="visible" />
</LinearLayout>
</RelativeLayout>
Now, u need to create Custom BaseAdapter like:
public class BaseAdapter2 extends BaseAdapter {
private Activity activity;
// private ArrayList<HashMap<String, String>> data;
private static ArrayList title,notice;
private static LayoutInflater inflater = null;
public BaseAdapter2(Activity a, ArrayList b, ArrayList bod) {
activity = a;
this.title = b;
this.notice=bod;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return title.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.row_listitem, null);
TextView title2 = (TextView) vi.findViewById(R.id.txt_ttlsm_row); // title
String song = title.get(position).toString();
title2.setText(song);
TextView title22 = (TextView) vi.findViewById(R.id.txt_ttlcontact_row2); // notice
String song2 = notice.get(position).toString();
title22.setText(song2);
return vi;
}
}
Now, u can set up your main activity like:
public class MainActivity extends Activity {
ArrayList<String> title_array = new ArrayList<String>();
ArrayList<String> notice_array = new ArrayList<String>();
ListView list;
BaseAdapter2 adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = (ListView) findViewById(R.id.listView1);
new TheTask().execute();
}
class TheTask extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... params) {
String str = null;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
String response = result.toString();
try {
JSONArray new_array = new JSONArray(response);
for (int i = 0, count = new_array.length(); i < count; i++) {
try {
JSONObject jsonObject = new_array.getJSONObject(i);
title_array.add(jsonObject.getString("title").toString());
notice_array.add(jsonObject.getString("notice").toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter = new BaseAdapter2(MainActivity.this, title_array, notice_array);
list.setAdapter(adapter);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
// tv.setText("error2");
}
}
}
}

#Allen Chun , actually its not in my mind currently that what I have changed in my code to run my code perfectly. But I am sharing all my codes which are working perfectly.
Its my layout code,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/fsr"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Notice Board"
android:textSize="20px" />
<TextView
android:id="#+id/err_msg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""
android:gravity="center" />
<ListView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/list_notice2"
android:layout_gravity="center" />
</LinearLayout>
This is my custom listview layout codes,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView"
android:paddingTop="10dp"
android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium" />
/>
<TextView
android:id="#+id/notice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Small Text"
android:paddingTop="5dp"
android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceSmall" />
</LinearLayout>
its my activity named "NoticeBoard" .
public class NoticeBoard extends Activity {
ArrayList<String> title_array = new ArrayList<String>();
ArrayList<String> notice_array = new ArrayList<String>();
ListView list;
base_adapter3 adapter;
TextView f,msg;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list_notice);
list = (ListView) findViewById(R.id.list_notice2);
msg=(TextView) findViewById(R.id.err_msg);
new test_ays().execute();
}
class test_ays extends AsyncTask<Void, Void, String> {
#Override
protected String doInBackground(Void... params) {
String str = null ;
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/BSDI/show.php");
HttpResponse response = httpclient.execute(httppost);
str = EntityUtils.toString(response.getEntity());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return str;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if(result!=null) // add this
{
String response = result.toString();
try {
JSONArray new_array = new JSONArray(response);
for (int i = 0, count = new_array.length(); i < count; i++) {
try {
JSONObject jsonObject = new_array.getJSONObject(i);
title_array.add(jsonObject.getString("title").toString());
notice_array.add(jsonObject.getString("notice").toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter = new base_adapter3(NoticeBoard.this, title_array, notice_array);
list.setAdapter(adapter);
// f=(TextView) findViewById(R.id.textTuh);
// f.setText(title_array);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
// tv.setText("error2");
}
}
else{
msg.setText("You need a working data connection...");
}
}
}
}
And its my custom baseadapter codes,
public class base_adapter2 extends BaseAdapter {
private Activity activity;
//private ArrayList<HashMap<String, String>> data;
private static ArrayList title,notice;
private static LayoutInflater inflater = null;
public base_adapter2(Activity a, ArrayList b) {
activity = a;
this.title = b;
// this.notice=bod;
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return title.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = inflater.inflate(R.layout.bsdi_adapter, null);
TextView title2 = (TextView) vi.findViewById(R.id.txt1); // title
String song = title.get(position).toString();
title2.setText(song);
return vi;
}
}

try {
URL twitter = new URL(

URLConnection tc = twitter.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
tc.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
JSONArray ja = new JSONArray(line);
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = (JSONObject) ja.get(i);
listItems.add(jo.getString("text"));
}
}
} catch (MalformedURLException e) {

} catch (IOException e) {
// TODO Auto-generated catch block

} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return listItems;
}
}
Please direct your attention on the listItems.add(jo.getString(“text”)); line. This is the part that I am grabbing a “text” attribute/property of single JSON object. To get a more “visual” picture of all available attributes/properties you might want to take a look at the XML version of twitters public timeline. This way you will get nice colored XML in your browser, where you can see all available attributes.

How to make elements(dynamic) obtained as JSON response, clickable in Android and connecting them to some web link?

The following is the CODE I am using to get the data from Codeforces.com API as JSON response. If anyone can please help me improve this to convert them to clickable links and then attach a web link to them. :
public class Http extends Activity {
TextView httpStuff;
HttpClient client;
JSONObject json;
final static String URL = "http://codeforces.com/api/user.status?handle=";
String m = "";
public static String[] sarr = new String[200];
public static String[] name = new String[200];
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.httpex);
httpStuff = (TextView)findViewById(R.id.tvHttp);
client = new DefaultHttpClient();
new Read().execute("result");
}
public JSONObject lastSub(String username) throws ClientProtocolException, IOException, JSONException {
StringBuilder url = new StringBuilder(URL);
url.append(username);
HttpGet get = new HttpGet(url.toString());
HttpResponse r = client.execute(get);
int status = r.getStatusLine().getStatusCode();
if(status == 200) {
HttpEntity e = r.getEntity();
String data = EntityUtils.toString(e);
JSONObject last = new JSONObject(data);
//JSONObject last = new JSONObject(data).getJSONArray("result").getJSONObject(0).getJSONObject("problem");
JSONArray array = new JSONObject(data).getJSONArray("result");
String m1=null, m2=null, m3=null;
String n1 = System.getProperty("line.separator");
int cnt=0, flag=0;
for(int k=0; k<array.length(); k++)
{
last = array.getJSONObject(k).getJSONObject("problem");
JSONObject v = array.getJSONObject(k);
if(v.getString("verdict").contentEquals("OK")) {
m1 = last.getString("name");
m2= last.getString("contestId");
m2= m2.concat("/");
m3= last.getString("index");
m2 = m2.concat(m3);
flag = 0;
for(int i=0; i<cnt; i++) {
if (sarr[i].equals(m1)) {
flag = 1;
}
}
if(flag == 0) {
m = m.concat(m1);
m= m.concat(n1);
sarr[cnt] = m1;
name[cnt] = m2;
cnt++;
}
}
}
return last;
}
else {
Toast.makeText(Http.this, "error", Toast.LENGTH_SHORT);
return null;
}
}
public class Read extends AsyncTask <String, Integer, String> {
#Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
try {

Make sure your main layout R.layout.httpex has a ListView.
(Should look like this)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
Create a new layout list_item.xml representing the data you want to display :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/pTitle"
android:textAppearance="#android:style/TextAppearance.DeviceDefault.Medium"
android:padding="10dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/pUrl"
android:visibility="gone" />
</LinearLayout>
Then edit your code like this :
public class Http extends Activity {

JSONObject v = array.getJSONObject(k);
if (v.getString("verdict").contentEquals("OK")) {
HashMap<String, String> d = new HashMap<String, String>();
d.put("NAME",last.getString("name"));
d.put("URL","http://codeforces.com/problemset/problem/"+last.getString("contestId")+"/"+last.getString("index"));
if(!problemdata.contains(d)) {
m = m.concat(last.getString("name")).concat(n1); //m+=last.getString("name")+"\r\n";

return last;
} else {

return null;
}
}

You have to download that image and show in the image view

You didn't post the code for imageLoader.DisplayImage() but I think this is where you download the image and set's to the ImageView.
From the image you attached, I would say that you need to call invalidate() on the ImageView after adding the photo to it via setImage() or setBackground().
