    primarykey
    data
    text
    <p>I'm a new programmer and I'm making an app which can get data from MYSQL to php and then display on android. I've been trying to find a solution but none of the tutorials I've seen so far seems to work for me, I've only managed to get one object from json into a single textview. But what I really need is to get data to be displayed on individual rows on listview.</p> <p>here's my JSON output,</p> <pre><code> [{"id":"1","name":"darrel","password":"pass1234"},{"id":"2","name":"garrett","password":"important"},{"id":"3","name":"neoys","password":"yseniopass"},{"id":"4","name":"john","password":"mikel123"},{"id":"5","name":"owen","password":"mike4l"}] </code></pre> <p>and my java code which gets only one of the users displayed onto a textview.</p> <pre><code> package com.darre.jsonreader; import android.annotation.SuppressLint; import android.annotation.TargetApi; import android.app.Activity; import android.app.ListActivity; import android.os.Build; import android.os.Bundle; import android.os.StrictMode; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TextView; import org.apache.http.HttpResponse; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject; @TargetApi(Build.VERSION_CODES.GINGERBREAD) public class Users extends ListActivity { /** Called when the activity is first created. */ @TargetApi(Build.VERSION_CODES.GINGERBREAD) @SuppressLint("NewApi") @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //listView.setOnItemClickListener(new OnItemClickListener() { // public void onItemClick(AdapterView&lt;?&gt; parent, View view, // int position, long id) { // When clicked, show a toast with the TextView text // Toast.makeText(getApplicationContext(), // ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); if (android.os.Build.VERSION.SDK_INT &gt; 9) { StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); } HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://172.30.54.153/databases/"); TextView textView = (TextView)findViewById(R.id.textView1); ListView listview = (ListView)findViewById(R.id.listView1); try { HttpResponse response = httpclient.execute(httppost); String jsonResult = inputStreamToString(response.getEntity().getContent()).toString(); JSONArray mArray = new JSONArray(jsonResult); for (int i = 0; i &lt; mArray.length(); i++) { JSONObject object = mArray.getJSONObject(i); String name = object.getString("name"); String password = object.getString("password"); textView.setText(name + " - " + password); } } catch (JSONException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } </code></pre> <p>Thanks in advance!!!</p>

    1. COuse a custom listview. http://stackoverflow.com/questions/10816243/search-in-listview-with-edittext/15367403#15367403. Just add json data in the for loop.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
