How to update points between CardViews in a RecyclerView

I'm working on a quiz app where there is one question and five radio buttons per CardView in a RecyclerView. Each radio button has an assigned score.
For Example, there are two CardViews
CardView #1
radio_button_1 = -20
radio_button_2 = -10
radio_button_3 = 0
radio_button_4 = 10
radio_button_5 = 20
CardView #2
radio_button_1 = -20
radio_button_2 = -10
radio_button_3 = 0
radio_button_4 = 10
radio_button_5 = 20
Say user picks radio_button_1 on CardView #1 and he picks radio_button_3 on CardView #2 and so forth. I want to add the points between CardViews and be able to preserve/ save those points as user scrolls through the CardViews. I don't know how it works with RecyclerView. SharedPreferences?
I have added a text view to test and see if the score is being updated in the background with the new score.
Recycler Adapter:
public class MainAdapter extends RecyclerView.Adapter<MainAdapter.ViewHolder> {
private List<App> mApps;
public static int score;
public static int updateScore() {
return score;
}
public MainAdapter(List<App> apps) {
mApps = apps;
}
#Override
public MainAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.cards_adapter, parent, false);
ViewHolder vh = new ViewHolder(v);
return vh;
}
#Override
public int getItemViewType(int position) {
return (position);
}
#Override
public void onBindViewHolder(final ViewHolder holder, int position) {
App app = mApps.get(position);
holder.questionTextView.setText(app.getQuestion());
}
#Override
public int getItemCount() {
return mApps.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private TextView questionTextView;
private TextView titleTextView;
public RadioGroup radioGroup;
public RadioButton rb1, rb2, rb3, rb4, rb5;
public ViewHolder(View itemView) {
super(itemView);
radioGroup = itemView.findViewById(R.id.radio_group);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
int selectedValue = 0;
switch (checkedId) {
case R.id.radio_button_1:
selectedValue -= 20;
break;
case R.id.radio_button_2:
selectedValue -= 10;
break;
case R.id.radio_button_3:
selectedValue += 0;
break;
case R.id.radio_button_4:
selectedValue += 10;
break;
case R.id.radio_button_5:
selectedValue += 20;
break;
}
updateValue (selectedValue);
}
public int updateValue(int selectedValue) {
/**Only to test if value is being tallied**/
TextView valueView = titleTextView.findViewById(R.id.title);
valueView.setText(String.valueOf(selectedValue));
return selectedValue;
}
});
questionTextView = itemView.findViewById(R.id.question);
titleTextView = itemView.findViewById(R.id.title);
rb1 = itemView.findViewById(R.id.radio_button_1);
rb2 = itemView.findViewById(R.id.radio_button_2);
rb3 = itemView.findViewById(R.id.radio_button_3);
rb4 = itemView.findViewById(R.id.radio_button_4);
rb5 = itemView.findViewById(R.id.radio_button_5);
}
#Override
public void onClick(View v) {
Log.d("App", mApps.get(getAdapterPosition()).getQuestion());
}
}}

You can declare an interface inside MainAdapter, lets call it ScoreUpdatesListener. It has one method that will be called whenever you want to update the textView.
You will need to implement that interface in your MainActivity, you may do it anonymously, or have the class itself implements that interface. like class MainActivity implements MainAdapter.ScoreUpdatesListener {}.
Either way, you need to pass that interface implementation to the adapter and save its reference. You may do it in the constructor, or add a set method to the adapter.
Now, when updating viewHolder's value, call that listener and it will update the textView from the activity.
class MainAdaptaer {
private ScoreUpdates listener;
...
class ViewHolder... {
...
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
int selectedValue = 0;
switch (checkedId) {
case R.id.radio_button_1:
selectedValue -= 20;
break;
case R.id.radio_button_2:
selectedValue -= 10;
break;
case R.id.radio_button_3:
selectedValue += 0;
break;
case R.id.radio_button_4:
selectedValue += 10;
break;
case R.id.radio_button_5:
selectedValue += 20;
break;
}
score += selectedValue;
// score is an existing attribute of MainAdapter
// it can and should be non static attribute
listener.updateScore(score);
}
}
interface ScoreUpdatesListener {
void onScoreUpdate(int score);
}
}
In your activity:
private void setupMainAdapter() {
List<App> apps = getApps();
MainAdapter adapter = new MainAdapter(apps, new MainAdapter.ScoreUpdatesListener() {
#Override
public void onScoreUpdate(int score) {
TextView valueView = titleTextView.findViewById(R.id.title);
valueView.setText(String.valueOf(score));
}
});
mRecyclerView.setAdapter(adapter);
}
If the class itself implemented the interface, just pass this to the adapter.
You don't have to move the TextView handling to the activity, but you should. The adapter shouldn't mess with views that isn't ViewHolders

Here is what I have now

TextView breaks my word by letters

My requirements: create "incoming bubble" with width by content and max width 90%.
I have this markup:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1.0"
tools:background="#color/white_smoke">
<LinearLayout
android:id="#+id/flBubble"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:background="#drawable/bubble_in"
android:layout_weight="0.9">
<ImageView
android:id="#+id/ivSay"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="?android:attr/selectableItemBackground"
android:contentDescription="#string/default_content_description"
android:padding="8dp"
android:src="#drawable/ic_play_circle_outline_black_24dp"
android:tint="#color/primary"/>
<TextView
android:id="#+id/tvValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:padding="8dp"
android:textColor="#color/black"
android:textSize="16sp"
tools:text="I would like to go to an Italian restaurant"/>
</LinearLayout>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0.1"/>
</LinearLayout>
Sometimes I get the following result:
But I expect the following result (it's falsely encouraging screenshot from Android Studio preview):
How can I prevent breaking word restaraunt by letters?
UPDATE
Although I use minSdk=15 I tried to use breakStrategy and I haven't get expected result.
android:breakStrategy="simple":
android:breakStrategy="balanced":
I found a related question: Force next word to a new line if the word is too long for the textview, but I didn't undestand how can I get maximum available width for TextView with layout_width="wrap_content?
It would be great if I could override the TextView.setText and place line breaks there if needed.

OMG, there were in my string!
value.replaceAll("\\s", " ");
Thank you all!

Use MaxWidth property for textview or else you should provide width for textview
<com.custom.views.CustomTextView
android:id="#+id/txt_send_chat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="center_vertical"
android:maxWidth="250dp"
android:textColor="#color/color_chat_sender"
android:textSize="16sp"
app:font_name="#string/font_roboto_regular" />

You can use webview to achieve this behavior.
In webview you can use css to adjust text.
Take a look at this answer
Update
You can calculate width of string and add \n to string where is string needs to split
Rect bounds = new Rect();
Paint textPaint = textView.getPaint();
textPaint.getTextBounds(text, 0, text.length(), bounds);
int height = bounds.height();
int width = bounds.width();
Results is in pixels, so just check width of your view or screen and split the string.
UPDAE2: Example Code
I just wrote an example with simple layout in activity onCreate you can implement it in adapter or whatever works for you.
TextView textView = (TextView) findViewById(R.id.txt); //textview with empty text
Rect bounds = new Rect();
Paint textPaint = textView.getPaint();
String text = "some long text here.....";// text data to work on
textPaint.getTextBounds(text, 0, text.length(), bounds);
int textWidth = bounds.width();// get text width in pixel
int marginPadding = 100;// we have some padding and margin from xml layouts
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int rootWidth = displayMetrics.widthPixels-marginPadding;// maximum width on screan
if (textWidth > rootWidth) { // check if need to split the string.
int lineMax = (text.length() * rootWidth) / textWidth; // maximum Characters for each line
String result = text.replaceAll("(.{" + String.valueOf(lineMax) + "})", "$1\n"); // regex to replace each group(lineMax) of Chars with group of char + new line
textView.setText(result);
} else
textView.setText(text);
UPDATE#3: Fixed code for Listview
onCreate
ArrayList<String> data = new ArrayList<>();
data.add("000");
data.add("aaaaaaaaaaa");
data.add("aaaaaaaaaaa bbbbbbbbbbbb");
data.add("aaaaaaaaaaa bbbbbbbbbbbb cccccccccccccccc");
data.add("aaaaaaaaaaa bbbbbbbbbbbb cccccccccccccccc ddddddddddddd");
data.add("aaaaaaaaaaa bbbbbbbbbbbb cccccccccccccccc ddddddddddddd eeeeeeeeeeeee");

You can try with
Autosizing TextViews
The Support Library 26.0 provides full support to the autosizing TextView feature on devices running Android versions prior to Android 8.0 (API level 26). The library provides support to Android 4.0 (API level 14) and higher. The android.support.v4.widget package contains the TextViewCompat class to access features in a backward-compatible fashion
For Example:
<TextView
android:layout_width="match_parent"
android:layout_height="200dp"
android:autoSizeTextType="uniform" />
For more details Guidelines go HERE
Their is Library too HERE

Try this
private String getWidthFitString(String input) {
Paint paint = text.getPaint();
// you can define max width by your self
int maxWidth = getContentMaxWidth();
float width = paint.measureText(input);
if (width > maxWidth) {
List<String> words = Arrays.asList(input.split("\\s"));
int breakLinePosition = 0;
String toBreakLineText;
List<String> toBreakLineWords = new ArrayList<>();
while (breakLinePosition < words.size()) {
toBreakLineWords.add(words.get(breakLinePosition));
toBreakLineText = TextUtils.join(" ", toBreakLineWords);
float currentWidth = paint.measureText(toBreakLineText);
if (currentWidth > maxWidth) {
break;
}
breakLinePosition ++;
}
if (breakLinePosition > 1) {
toBreakLineWords.remove(toBreakLineWords.size() - 1);
toBreakLineText = TextUtils.join(" ", toBreakLineWords);
List<String> fromBreakLineWords = new ArrayList<>();
for (int i = breakLinePosition; i < words.size(); i++) {
fromBreakLineWords.add(words.get(i));
}
return toBreakLineText + "\n" + getWidthFitString(TextUtils.join(" ", fromBreakLineWords));
} else {
return input;
}
}
return input;
}

For those whose string has non-breaking space character may try the following:
value.replace("\u00A0", " ")
Hope this might help

Change your TextView to EditText and put this 2 lines. it should help you
android:inputType="textMultiLine"
android:enabled="false"
This will place you text properly and later on you can give a edit feature in your application if you need.

Android: Get values of listview with multiple row layout

I have a listview with multiple row layouts (radio group, edit text, text view), with multiple choice mode. I want to retrieve it's selected data (user-selected or typed data) on a submit button.
This is the code from my main file:
public class GraduatingSurvey extends Fragment {
private static final String LOGTAG = "log" ;
public String stdcode = "024-15-16079";
Button submit;
RadioGroup radioGroup;
RadioButton radioButton;
EditText comment;
ArrayList<GraduatingSurveyModel> graduatingModelList;
ListView listView;
View view;
public GraduatingSurvey() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
view = inflater.inflate(R.layout.fragment_graduating_survey, container, false);
submit = (Button) view.findViewById(R.id.btn_graduate_submit);
listView = (ListView) view.findViewById(R.id.graduate_list);
graduatingModelList = new ArrayList<GraduatingSurveyModel>();
//handle submit form Event.
submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final int child=listView.getAdapter().getCount();
Log.i("radio", "child: " + child);
SparseBooleanArray checked = listView.getCheckedItemPositions(); //Is returning empty
Log.i("radio", "sparseArray: " + checked);
for(int i=0;i<child;i++) {
int type = listView.getAdapter().getItemViewType(i);
Log.i("radio", "type: " + type);
if(type == 2){
// Want to retrieve data here
}
if(type == 0)
{
}
if(type == 1){
}
}
}
});
NetAsync(view);
return view;
}
This is the adapter:
public class GraduatingSurveyAdapter extends ArrayAdapter<GraduatingSurveyModel> {
private static final int TYPE_ITEM1 = 0;
private static final int TYPE_ITEM2 = 1;
private static final int TYPE_ITEM3 = 2;
int type;
ArrayList<GraduatingSurveyModel> ArrayListSurvey;
int Resource;
Context context;
LayoutInflater vi;
public GraduatingSurveyAdapter(Context context, int resource, ArrayList<GraduatingSurveyModel> objects) {
super(context, resource, objects);
ArrayListSurvey = objects;
Resource = resource;
this.context = context;
vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getItemViewType(int position) {
if (position == 14){
type = TYPE_ITEM1;
} else if (position == 23 || position == 24 || position == 25){
type = TYPE_ITEM2;
}
else
{
type= TYPE_ITEM3 ;
}
return type;
}
#Override
public int getViewTypeCount() {
return 3;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
//first Item or row is being created hence ConvertView is NULL

How can I retrieve the data submitted in the main fragment?
Thanks

For this You can create a custom class with row values like,
Arraylist<CustomClass> mnewList = new ArrayList();
Class CustomClass
{
private String edValues,
private int rowId,
}
etc.
Then Implement on change listener for radio button in that add/remove current selected items to that custom list.

Is there a way to make an automatic slideshow using imageswitchers and galleries?

I'm having trouble thinking about how to make an automatic slideshow using ImageSwitchers and Gallery. The only thing I understand is the animation between transitioning pictures when you select them from gallery, like the way they fade or move from left to right.
EDIT
My purpose is trying to make a slideshow the same way when you create gallery and select each pictures then use imageswitcher to display the selected picture on the bottom layout. Just this time, instead actually clicking, I want the pictures to move automatically (next one after the last one), like on Powerpoints and with a timer obviously.
Here's the whole class:
package project.CaseStudy;
public class Slideshow extends Activity implements ViewFactory {
//---the images to display---
Integer[] imageIDs = {
R.drawable.pic1,
R.drawable.pic2,
R.drawable.pic3,
R.drawable.pic4,
R.drawable.pic5,
R.drawable.pic6,
R.drawable.pic7
};
TextView legend;

CheckBox image;

text = (CheckBox) findViewById(R.id.text);
//text.setEnabled(true);
//image.setEnabled(true);
//repeat.setEnabled(true);
imageSwitcher = (ImageSwitcher) findViewById(R.id.switcher1);
imageSwitcher.setFactory(this);
imageSwitcher.setInAnimation(AnimationUtils.loadAnimation(this,
android.R.anim.fade_in));
imageSwitcher.setOutAnimation(AnimationUtils.loadAnimation(this,

Ignore the last two methods if it's too complicated to understand Im just sketching my program and will eventually fix the redundancy later.

I'm not sure exactly what you're trying to achieve, but the best (read: easiest) way I know of to create a small slideshow is to simply put your imageViews and/or textViews into a frame layout. Then in your code, you would use a switch statement that sets the visibility of each image.
eg. case 0:
image1.setVisibility (View.VISIBLE);
image2.setVisibility (View.INVISIBLE);
Etc....
