Customizing Android ListView with Custom Adapter

Customizing Android ListView with Custom Adapter - java

I'm working on a List View with Custom Adapter but it seems that my code isn't working. I don't know what is wrong. Can someone help me. Here's the code that I did:

Thank you!

First of all you don't have model class named Student Even though you are declaring them as Student. Replace them with String.
Write in this way
String student_data[] = new String[]
{
new String("Ace"),
new String("Brian"),
new String("Cathy"),
new String("Dave"),
new String("Ethel")
};
StudentRecordCustomAdapter adapter = new StudentRecordCustomAdapter(StudentRecord.this,R.layout.student_row,student_data,score);
And Recieve them like this
public StudentRecordCustomAdapter(Context context, int layoutResourceId, String data[], String[] score) {
super(context, layoutResourceId, data);
// TODO Auto-generated constructor stub
this.ctx = context;
this.layoutResourceId = layoutResourceId;
this.data = data;
this.score = score;
}
This is wrong..
String student = data[position];
You can access and set your variable To textView Directly.. Like
holder.studentTextView.setText(data[position]);
Review your code. Change them And try again what you want to do...

I suggest to always extend BaseAdapter for every single custom Adapter that you need to use in your App. Your code seems fine.

You repeat this line twice holder.scoreTextView = (TextView) convertView.findViewById(R.id.scoreTextView); second tine you must do holder.scoreTextView.setText(data[position])

How to add multiple values inside 1 list view and style it approriatle

I want to be able to add multiple values on a list but properly style the list view.
For example right now the list view will look like this:
namepostcodedate
which is because of the following code
ListArray.add(jobs.get(finalJ).customer.getName() + job.getPostcode() + job.getDate());
The way that I am currently adding the values in the ListArray doesn't seem ideal but I am not sure if there is another way to do this and display the list formated?
This is my list_item file
<?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="wrap_content"

android:layout_width="match_parent"
android:layout_height="wrap_content"

<TableRow
android:id="#+id/rows2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/ddOrangeLight"
android:showDividers="middle">
<!-- android:divider="?android:attr/dividerHorizontal"-->
<TextView
android:id="#+id/customerNameView"
android:layout_width="wrap_content"
android:layout_height="match_parent"

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){
}
}
}

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);
}

This should work:
ListView listView = getListView();
ImageView mListHeader = new ImageView(getContext());
mListHeader.setImageResource(R.drawable.individuals_img);
mListHeader.setScaleType(ImageView.ScaleType.FIT_XY);
mListHeader.setLayoutParams(new AbsListView.LayoutParams(1400,974));
mListHeader.requestLayout();
listView.addHeaderView(mListHeader);

Inflate a custom layout as your listview header and add below imageview to it
code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView list = (ListView) findViewById(R.id.list);
View header = getLayoutInflater().inflate(R.layout.header, list, false); //custom layout
list.addHeaderView(header, null, false);
}
try this: in your header.xml add the header image
<ImageView
android:id="#+id/imageView"
android:layout_width="120dp"
android:layout_height="120dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"

Android : Creating a vertical space for ImageView and tab

I am working on an Android project in which I am creating UI for editing a Note object in the app. For that, I will be replicating the UI which is designed with JS,HTML,CSS. Unfortunately, android has discrete elements like ListView, TextView and all. As you can see in the screenshot, the top horizontal bar is just a representation and inside it contains a photo.
Also, there is a tab like option in the activity itself. I don't know how to create both these things. The choice of colour I am planning to create with a List and get the element clicked in the List. I have basic functionality working, and working on UI part now.
I don't know what all is required for creating such fancy UI's. Any help would be nice.

Kindly let me know. Thank you.

For the top horizontal bar you definitely need a compound custom view like this:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android" >
<ImageView
android:id="#+id/background
android:layout_width="match_parent"
android:layout_height="20dp"
android:layout_centerVertical="true"
/>
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/profileImageView"
android:layout_marginLeft="16dp"
/>
<ImageView
android:id="#+id/profileImageView"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_alignParentLeft="true"
android:layout_marginLeft="20dp"
android:layout_centerVertical="true"
/>
</merge>
With code like this:
public class TopBarView extends RelativeLayout {
private TextView title;
private ImageView profileImage;
public TopBarView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.TopBarView, 0, 0);
String titleText = a.getString(R.styleable.TopBarView_titleText);
a.recycle();
setGravity(Gravity.CENTER_VERTICAL);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.view_top_bar, this, true);
title = (TextView) findViewById(R.id.title);
title.setText(titleText);
profileImage = (ImageView) findViewById(R.id.profileImageView);
profileImage.setBackgroundColor(R.color.yellow);
profileImage.setImageResource(R.drawable.myProfileDrawable);
setBackgroundColor(Color.TRANSPARENT);
}
For tab options you could use android.support.design.widget.TabLayout from design support library.

Change your code in
#Override
public CardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.R.layout.client_info_fragment_revision_layout, parent, false);
CardViewHolder holder = new CardViewHolder (view);
}

It's just for debug purpose:
If you are using Android studio then open your R.java under folder
build->generated->source->r->debug->yourpackagename->R.java
Then search 0x7f0d00aa in the file; It will be like
public static final int TextView01=0x7f0d00aa;
Search the corresponding ID in xml files under resources folder. Then check the XML content syntax,naming,source etc.

Customizing Android ListView with Custom Adapter - java

I suggest to always extend BaseAdapter for every single custom Adapter that you need to use in your App. Your code seems fine.

You repeat this line twice holder.scoreTextView = (TextView) convertView.findViewById(R.id.scoreTextView); second tine you must do holder.scoreTextView.setText(data[position])
