Android ExpandableListView does not expand/not clickable

Android ExpandableListView does not expand/not clickable - java

i'm pretty new to android programming and tried to implement a basic expandable listview showing a list of Courses which should show some additional details when clicked. i feel like the problem is very basic as i don't include anything fancy in any of the views, but i still could not find a solution online, most of the other questions are a lot more specific.
The first part works fine(displaying the list of courses), the problem is that the list is not clickable, meaning it does not expand.
what i have determined right now is the following:
1. the getChildView is never called(debugger never stops at breakpoint)
2. there is data for the children as it's the same data that's used for the groupheading which works fine.
I have also tried to set an onGroupClickListener which was never called, so i removed it again.
my code:
Group heading layout:
<TextView
android:id="#+id/CourseName"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="bottom"
android:text="CourseName"
android:layout_weight="7"
android:layout_marginRight="25dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/CourseDate"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="bottom"
android:layout_weight="3"
android:text="CourseDate" />

thanks a lot in advance!
EDIT:
i found it by chance. the checkbox inside the groupheader was focusable, stealing all the clicks away from the list. to solve this problem simply set the focusable attribute of the checkbox/button in your list to false.

I found it by chance. the checkbox inside the groupheader was focusable, stealing all the clicks away from the list. to solve this problem simply set the focusable attribute of the checkbox/button in your list to false with either:
in Java:
checkbox.setFocusable(false);
OR, in xml:
android:focusable="false"

i was facing the same issue but what i added the below line to my Parent view
android:descendantFocusability="blocksDescendants"
and it worked for me.

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 = "[{\"username\":\"MikiThenics\",\"pullups\":\"25\",\"pushups\":\"70\",\"dips\":\"30\",\"handstandpushups\":\"16\",\"muscleups\":\"8\",\"pistolsquats\":\"1\",\"plank\":\"360\"},{\"username\":\"user01\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user02\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user0\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user1\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user2\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user3\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user4\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user5\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user6\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user7\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user8\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user9\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user10\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user11\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user12\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user13\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user14\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user15\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user16\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user17\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user18\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user19\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user20\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user21\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user22\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user23\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user24\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user25\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user26\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"muscleups\":\"0\",\"pistolsquats\":\"0\",\"plank\":\"0\"},{\"username\":\"user27\",\"pullups\":\"0\",\"pushups\":\"0\",\"dips\":\"0\",\"handstandpushups\":\"0\",\"mu

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.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

<TextView

android:textSize="16sp"
android:layout_alignParentStart="true"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="#+id/username"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="12dp"
android:text="Name"
android:textColor="#000000"
android:textColorHighlight="#000000"
android:textColorHint="#000000"
android:textColorLink="#000000"
android:textSize="16sp"
android:layout_toEndOf="#+id/rank"
/>
<TextView
android:id="#+id/score"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:text="SCORE"
android:textColor="#000000"
android:textColorHighlight="#000000"
android:textColorHint="#000000"
android:textColorLink="#000000"
android:textSize="16sp"
android:layout_alignParentEnd="true" />
</RelativeLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

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);
}

Android ListView not scrolling at all

I've a ListView that gets populated from a JSON response.
The results go beyond the screen and whatever I tried the listview won't be scrolling.
Currently the XML looks like the following:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".DrinkActivity">
<ListView
android:id="#+id/drinkList"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:scrollbarSize="3dp"
android:scrollbarStyle="outsideOverlay"
android:scrollbars="vertical"
android:scrollingCache="true"
android:smoothScrollbar="true" />
</LinearLayout>
Adapter which the listview is using:
package com.example.tijn.bartenderapp;

Here is the method that sets the ListView :
#Override
public void processFinish(Object output) {
String jsonString = output.toString();
Gson gson = new Gson();
ArrayList<Drink> drinks = gson.fromJson(jsonString, new TypeToken<List<Drink>>(){}.getType());
final ListView listview = (ListView) findViewById(R.id.drinkList);
final DrinksAdapter adapter = new DrinksAdapter(this, R.layout.drinksrow, drinks);
listview.setAdapter(adapter);
listview.setEnabled(false);
}
Already tried to surround the LinearLayout with a ScrollView.
Anybody got an idea?

listview.setEnabled(false);
This disables scrolling.
Not sure why you want to set it to false.

You can use
<ScrollView
android:layout_width="..."
android:layout_height="...">
<LinearLayout
android:orientation="vertical"
android:layout_width="..."
android:layout_height="...">
I use it, and works.

Android: onItemClick and onItemLongClick do not respond

My Android app is composed of an SQLite database which populates individual ListView items with data user saves. Those items are available for display in activity_main.xml.
I have a class called RecordsListFragment which contains the two problematic methods: onItemClick and onItemLongClick. Here is the class in its entirety:

I haven't found a definite answer to my question, so I'm asking for a bit of help here.

You need set OnItemClickListener and OnLongItemClickListener to ListView, I edited your method in the initializing variable ListView:
private void findViewsById(View view) {
recordsListView = (ListView) view.findViewById(R.id.list_records);
recordsListView.setOnItemClickListener(this);
recordsListView.setOnItemLongClickListener(this);
}

Recyclerview is not displayed in fullscreen

Recyclerview is not displayed in fullscreen. Below is the layout file and the code I've written. After executing, the contents are displayed as shown in the below picture. The height is only the highlighted part. I want the contents to be fullscreen. I remaining contents are within this highlighted area which is scrollable. I want the contents to be displayed in fullscreen. Any help would be helpful.

You should use different layout for your viewholder. Take the RelativeLayout you have there, cut it out, put it in different xml file then pass it to onCreateViewHolder.

From look at your code - it looks like what is in the preview screenshot is the same as what is within the RelativeLayout you have staticly defined.
There is an issue with your approach. It is that you are referencing the RelativeLayout (within the same xml hierarchy as your RecylerView) as the CellViewHolder in the RecyclerView.Adapter. My approach personally is to create a seperate xml layout for the cell viewholder.
Follow this guide, it is very detailed:
https://guides.codepath.com/android/using-the-recyclerview

You should use different layout for your viewholder. Take the RelativeLayout you have there, cut it out, put it in different xml file then pass it to onCreateViewHolder.

The above coding has something work use different layout mean one for Recycleview and other for contents in list

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.
