Handeling adapters from list view to single item view class

Handeling adapters from list view to single item view class - java

I have a class viewroom.java, to list all the rooms' title from database, as follows:
package com.iwantnew.www;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import org.apache.http.NameValuePair;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.annotation.TargetApi;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.os.StrictMode;
//import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.TextView;
#TargetApi(Build.VERSION_CODES.GINGERBREAD)
public class viewroom extends ListActivity {
// url to make request
private static String url = "http://10.0.2.2/iWant/src/android_view_all_room.php";
// JSON Node names
private static final String TAG_ROOM = "room";
// private static final String TAG_SUCCESS = "success";
private static final String TAG_ID = "id";
private static final String TAG_LOCATION = "location";
private static final String TAG_TITLE = "title";
private static final String TAG_QUANTITY = "quantity";
private static final String TAG_PRICE = "price";
private static final String TAG_CONTACT = "contact";
private static final String TAG_AREA = "area";
private static final String TAG_DESCRIPTION = "description";
private static final String TAG_ADDRESS = "address";
// contacts JSONArray
JSONArray room = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view_room);
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
// Hashmap for ListView
ArrayList<HashMap<String, String>> roomList = new ArrayList<HashMap<String, String>>();
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
List<NameValuePair> params = new ArrayList<NameValuePair>();
// getting JSON string from URL
JSONObject json = jParser.makeHttpRequest(url, "GET", params);
try {
// Getting Array of Contacts
room = json.getJSONArray(TAG_ROOM);
// looping through All Contacts
for(int i = 0; i < room.length(); i++){
JSONObject c = room.getJSONObject(i);
// Storing each json item in variable
String id = c.getString(TAG_ID);
String location = c.getString(TAG_LOCATION);
String quantity = c.getString(TAG_QUANTITY);
String address = c.getString(TAG_ADDRESS);
String price = c.getString(TAG_PRICE);
String contact = c.getString(TAG_CONTACT);
String area = c.getString(TAG_AREA);
String description = c.getString(TAG_DESCRIPTION);
String title = c.getString(TAG_TITLE);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_ID, id);
map.put(TAG_LOCATION, location);
map.put(TAG_QUANTITY, quantity);
map.put(TAG_ADDRESS, address);
map.put(TAG_PRICE, price);
map.put(TAG_CONTACT, contact);
map.put(TAG_AREA, area);
map.put(TAG_DESCRIPTION, description);
map.put(TAG_TITLE, title);
// adding HashList to ArrayList
roomList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(this, roomList,
R.layout.list_room,
new String[] { TAG_TITLE, TAG_LOCATION, TAG_PRICE }, new int[] {
R.id.title, R.id.location, R.id.price });
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
// Launching new screen on Selecting Single ListItem
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String title = ((TextView) view.findViewById(R.id.title)).getText().toString();
String location = ((TextView) view.findViewById(R.id.location)).getText().toString();
String price = ((TextView) view.findViewById(R.id.price)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleRoomActivity.class);
in.putExtra(TAG_TITLE, title);
in.putExtra(TAG_LOCATION, location);
in.putExtra(TAG_PRICE, price);
startActivity(in);
}
});
}
}
when one of those list item is clicked, details are shown in single Room Activity class. it
is as follows:
package com.iwantnew.www;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
public class SingleRoomActivity extends Activity {
private static final String TAG_TITLE = "title";
private static final String TAG_LOCATION = "location";
private static final String TAG_PRICE = "price";
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.single_room);
// getting intent data
Intent in = getIntent();
// Get JSON values from previous intent
String title = in.getStringExtra(TAG_TITLE);
String location = in.getStringExtra(TAG_LOCATION);
String price = in.getStringExtra(TAG_PRICE);
// Displaying all values on the screen
TextView lblTitle = (TextView) findViewById(R.id.title_label);
TextView lblLocation = (TextView) findViewById(R.id.location_label);
TextView lblPrice = (TextView) findViewById(R.id.price_label);
lblTitle.setText(title);
lblLocation.setText(location);
lblPrice.setText(price);
}
}
there remains a big gap between each items in view room activity class, when all details are shown in single room activity.
and when list adapter is modified to
ListAdapter adapter = new SimpleAdapter(this, roomList,
R.layout.list_room,
new String[] { TAG_TITLE }, new int[] {
R.id.title });
in view room activity, the gap vanishes but, single room activity does not show all the description.
in case you need my xml files:

I want to vanish gap in the first picture and still get the second picture as it is.

Unexpected behaviour with custom ListView adapter

So I've got a listView and each item basically displays 3 TextView-s one of the TextView-s represents username and if the username is equal to the logged user the item shall be highlighted(see code)
import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import java.util.List;
public class ListAdapter extends ArrayAdapter<HallOfFame.User> {
private int resourceLayout;
private Context mContext;
public ListAdapter(Context context, int resource, List<HallOfFame.User> items) {
super(context, resource, items);
this.resourceLayout = resource;
this.mContext = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(mContext);
v = vi.inflate(resourceLayout, null);
}
HallOfFame.User user = getItem(position);
if (user != null) {
TextView rankText = v.findViewById(R.id.rank);
TextView usernameText = v.findViewById(R.id.username);
TextView scoreText = v.findViewById(R.id.score);
rankText.setText(Integer.toString(user.rank));
usernameText.setText(user.username);
scoreText.setText(Integer.toString(user.overall));
if(Utils.USERNAME.equals(user.username)){
usernameText.setTextColor(Color.RED);
}
}
return v;
}
}
In this example only MikiThenics should be highlighted. Adding else after if(Utils.USERNAME.eq...) will stop the other usernames from being highlighted but there's still this weird shift with the number on the right. And the items that are "not working" aren't always the same.
This is how the HallOfFame.User looks:
public class User{
public String username;
public int pullups=0,pushups,dips,handstandpushups,plank,pistolsquats,muscleups;
public int overall;
public int rank = 0;
public User(String data,int i){
try {
JSONObject jsonObject = new JSONObject(data);
username = jsonObject.getString(Utils.S_USERNAME);
pullups = jsonObject.getInt(Utils.S_PULL_UPS);
pushups = jsonObject.getInt(Utils.S_PUSH_UPS);
dips = jsonObject.getInt(Utils.S_DIPS);
handstandpushups = jsonObject.getInt(Utils.S_HANDSTAND_PUSHUPS);
plank = jsonObject.getInt(Utils.S_PLANK);
pistolsquats = jsonObject.getInt(Utils.S_PISTOL_SQUATS);
muscleups = jsonObject.getInt(Utils.S_MUSCLE_UPS);
overall = pullups+pushups+dips+handstandpushups+pistolsquats+muscleups+plank/60;
rank = i;
if(username.equals(Utils.USERNAME))
yourPosition = i;
}catch (Exception e){
}
}
}
This is the example of the JSON I'm using
String tmp =

The problem is caused by the username. Since setting username in User to fixed String solves the problem.
Even though I'm using fixed string as JSON the "not working items" aren't the same when restarting the activity.

It's a XML issue. You can try with this.

You can add an boolean into your if statement that at first it is true and when tries to highlited the username's text , set the boolean false
if(Utils.USERNAME.equals(user.username) && boolean){
usernameText.setTextColor(Color.RED);
}

How to handle NULL results from JSON when I click on list view row?

Very little experience when it comes to Java. My app pulls data from an API to a list view just fine. Once clicked on the list view I want to display more details. My code is in different files and I can't figure out how handle null results when I set my text view text. Right now it is giving me a few errors. Thank you in advanced. I've tried debugging and my own research to no avail for over a day.
My error was: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference.

You are trying to show your details screen but in your method you are finding view by id under your mMembersListScreen when you should use mMemberDetailsScreen. Try this:
public void populateMemberDetailsScreen(String _name, String _birthday, String _gender,
String _twitterId, String _numCommittees, String _numRoles) {
TextView tv = (TextView) mMemberDetailsScreen.findViewById(R.id.text_name);
tv.setText(_name);
tv = (TextView) mMemberDetailsScreen.findViewById(R.id.text_birthday);
tv.setText(_birthday);
tv = (TextView) mMemberDetailsScreen.findViewById(R.id.text_gender);
tv.setText(_gender);
tv = (TextView) mMemberDetailsScreen.findViewById(R.id.text_twitter_id);
tv.setText(_twitterId);
tv = (TextView) mMemberDetailsScreen.findViewById(R.id.text_num_committees);
tv.setText(_numCommittees);
tv = (TextView) mMemberDetailsScreen.findViewById(R.id.text_num_roles);
tv.setText(_numRoles);
}

where to put android.support.v4.widget.SwipeRefreshLayout and how to implement it?

just wanna ask where to put the android.support.v4.widget.SwipeRefreshLayout on my codes? I'm confused if it should be on my activity_main.xml or in my list_item.xml file..
Here is my activity_main.xml:

This will be the output that i want to have an SwipeRefresh effect..
Those output came from MySQL Database :

Thanks!

To add the swipe to refresh widget to an existing app, add SwipeRefreshLayout as the parent of a single ListView or GridView. Remember that SwipeRefreshLayout only supports a single ListView or GridView child. - Add the SwipeRefreshLayout Widget
So, your activity_main.xml should be 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" >
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout
</LinearLayout>
Implementation:
public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener{
private SwipeRefreshLayout swipeRefreshLayout
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeLayout);
swipeRefreshLayout.setOnRefreshListener(this);
//to change the color of the refresh indictor
swipeRefreshLayout.setColorScheme(getResources().getColor(R.color.yourcolor),
getResources().getColor(R.color.yourcolor),
getResources().getColor(R.color.yourcolor),
getResources().getColor(R.color.yourcolor));
}
#Override
public void onRefresh() {
//do something here
//setRefreshing(false) will hide the indicator
swipeRefreshLayout.setRefreshing(false);
}
}

It should wrap around the listview, something like this:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swiperefresh"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="8dp">
<android.widget.ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.widget.ListView>
</android.support.v4.widget.SwipeRefreshLayout>
If you're using Android Studio, you can look at a Swiperefresh sample:
File\New\Import Sample\ then search for "swipe..."
In your java code, you initialize the SwipeRefresh object exactly how you would do a TextView, Button or anything else, except in your onResume(), you also want to put something like this:
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
initiateRefresh();
}
});
and then inside initiateRefresh(), you do something like:
AssignData2ListView();
mSwipeRefreshLayout.setRefreshing(false);

Set TextView text with a for loop so multiple lines show

So I have a for loop that I want to output a new line in a textview every single time it goes through. However, I am not sure if that is possible. I have TableLayout in there but it put the items vertically instead of horizontally. I thought about ListView but not sure how to set the text of it.
Here is my code

Add android:inputType="textMultiLine" to the TextView in the XML.
And add data into TextView like this:
driveNumList.setText(driveNumList.getText().toString() + String.valueOf(driveNum) + System.getProperty("line.separator"));
And so on.
Edit: you can use "\n" instead of System.getProperty("line.separator") for adding the new line character.

I would recommend a ListView for this type of thing so that it is automatically scrollable, uses View recycling to maintain efficiency, cleans up your code and organizes it into digestible segments.
To use a ListView, you first need to add it to your main XML file. So that would become the following:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<!--Header aligned to top -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/header"
android:gravity="center"
android:background="#FC9">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/Drive_Number"
android:layout_margin="4dp"
android:textSize="20sp"
android:textColor="#000"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/Drive_Distance"
android:layout_toRightOf="#+id/Drive_Number"
android:layout_margin="4dp"
android:textSize="20sp"
android:textColor="#000"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/Drive_Time"
android:layout_toRightOf="#+id/Drive_Distance"
android:layout_margin="4dp"
android:textSize="20sp"
android:textColor="#000"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="vertical"
android:background="#005"
android:layout_below="#+id/header"
android:id="#+id/scrollableContents">
<ListView
android:id="#+id/listView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
</RelativeLayout>
Following that, you need to create your ListView adapter class. It is what handles what each individual list item's data is (the thing inside your for-loop).
Here is one that you might use, although you may have to make your own tweaks and import more of your own classes, add your package name to the top, etc.
So create a new Java class called DriveListAdapter.java and place the following code into it:
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import java.util.List;
import java.util.HashMap;
import java.util.Map;
public class DriveListAdapter extends ArrayAdapter<Map.Entry> {
private final Activity context;
// you may need to change List to something else (whatever is returned from drives.entrySet())
private final List<Map.Entry> drives;
// may also need to change List here (above comment)
public DriveListAdapter(Activity context, List<Map.Entry> drives) {
super(context, R.layout.drive_list_item, drives);
this.context = context;
this.drives = drives;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.drive_list_item, null, true);
Map.Entry drive = this.drives.get(position);
// position is the index of the drives.entrySet() array
int driveNum = position + 1;
// need to import your Route class
Route route = (Route) drive.getValue();
// need to import your DateTime class
DateTime startTime = new DateTime(route.getStart_time());
DateTime endTime = new DateTime(route.getEnd_time());
TextView driveNumList = (TextView) rowView.findViewById(R.id.Drive_Number_List);
TextView driveDistList = (TextView) rowView.findViewById(R.id.Drive_Distance_List);
TextView driveTimeList = (TextView) rowView.findViewById(R.id.Drive_Time_List);
driveNumList.setText(String.valueOf(driveNum));
driveDistList.setText(Double.parseDouble(route.getLen()) / 1000 + " km");
driveTimeList.setText((endTime.getMillis() - startTime.getMillis())/ 1000 + " s");
return rowView;
}
}
Then, create a new layout file, which will be what the individual list item looks like. This layout is rendered for each and every drive in the list. You can adjust this layout file so that everything is aligned properly. I gave an example of how to do that (create a layout file called drive_list_item.xml):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="4dp"
android:textSize="20sp"
android:textColor="#CCCCCC"
android:text="Medium Text"
android:id="#+id/Drive_Number_List"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="4dp"
android:textSize="20sp"
android:textColor="#CCCCCC"
android:text="Medium Text"
android:id="#+id/Drive_Distance_List"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="4dp"
android:textSize="20sp"
android:textColor="#CCCCCC"
android:text="Medium Text"
android:id="#+id/Drive_Time_List"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
And lastly, you just need to populate that ListView you created in the first step with this new adapter class.
So use the following method (populates the ListView instead of using the for loop):
private void populateView() {
this.getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
drives = APIRequestsUtil.getRoutes();
driveNumber = (TextView) myView.findViewById(R.id.Drive_Number);
driveDistance = (TextView) myView.findViewById(R.id.Drive_Distance);
driveTime = (TextView) myView.findViewById(R.id.Drive_Time);
driveNumber.setText("Drive Number");
driveDistance.setText("Drive Distance");
driveTime.setText("Drive Time");
// edit: you need to generate your List data from the entrySet
// the ArrayAdapter cannot take a Set argument - needs to be a List
List<Map.Entry> list = new ArrayList<Map.Entry>();
for (Map.Entry drive : drives.entrySet()) {
list.add(drive);
}
// populate the ListView
// may need to change "getActivity()" to something else
// this constructor needs the "this" context of the activity
DriveListAdapter drivesListAdapter = new DriveListAdapter(getActivity(), list);
ListView listView = (ListView)findViewById(R.id.listView);
listView.setAdapter(drivesListAdapter);
}
});
}

first of all you use LinearLayout instead of TableLayoyt
<LinearLayout
android:id="#+id/llMainLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical">

Please someone give me simple example or other help :)

Create this method:-
private static View createTabView(Context context, String tabText) {
View view = LayoutInflater.from(context).inflate(R.layout.custom_tab, null, false);
TextView tv = (TextView) view.findViewById(R.id.tabTitleText);
tv.setText(tabText);
return view;
}
Create custom_tab.xml file in layout folder
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/tabTitleText"
android:layout_width="#dimen/tabWidth"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:clickable="true"
android:paddingTop="#dimen/tabTopPading"
android:paddingBottom="#dimen/tabBottomPading"
android:paddingLeft="#dimen/tabLeftPading"
android:paddingRight="#dimen/tabRightPading"
android:textSize="#dimen/tabTextSize"
android:textColor="#color/themeColor"
android:background="#drawable/tab_selector"/>
finally set
tabHost.newTabSpec("Tab1").setIndicator(createTabView(getApplicationContext(),"Tab_name"))
