Cardview Rounded Corners are not showing up in Screenshot?

I'm trying take screenshot of a cardview which is in a DialogFragment. When I take a screenshot via Code. Top rounded corners are not showing but the bottom rounded corners are showing correctly. I saw these issues mentioned in the below Questions...
Cardview loses its radius when taken a screenshot programmatically
Using PixelCopy to copy a scaled View within a DialogFragment
As per the above question, I tested the same layout & code in a Fragment class. Then the rounded corners are showing up correctly...

Try the following as a replacement for ViewImage.kt in the referenced project. The main change is to pass in the view's window rather than an Activity. Dialogs have their own windows and don't share a window with activities.

I Noticed that you are trying to take a screenshot from 'mainRelative' which does not exist in your xml, I think you should use the id of 'cardView' or 'mainlinear' based on your requirements.

The Answer given by #Cheticamp is right
Lets Convert it into java
public class ScreenshotTaker {
private static final String TAG = ScreenshotTaker.class.getSimpleName();
/**
* Takes screenshot of given view and saves it in external storage
* #param view outer most ViewGroup that you want a screenshot of
* #return File object of saved screenshot in storage
*/
public static File captureScreenshot(View view) {
Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),
view.getHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
view.draw(canvas);
return saveBitmap(view.getContext(),bitmap);
}
public interface screenshotFile{
void onComplete(File file);
}
public static void getScreenShotFromView(View view, Window window, screenshotFile callback ) {
Bitmap bitmap;
// PixelCopy is available since API 24 but doesn't seem to work 100% until API 29.
// The build version statement can be adjusted according to how well PixelCopy
// works in your environment before "P".
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
int[] locationOfView = new int[2];
view.getLocationInWindow(locationOfView);
Rect rect = new Rect(locationOfView[0], locationOfView[1],
locationOfView[0] + view.getWidth(), locationOfView[1] + view.getHeight());
bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
try {
PixelCopy.request(window, rect, bitmap, new PixelCopy.OnPixelCopyFinishedListener() {

Show hide alternate LinearLayouts when selecting RadioButton in 2 RadioGroups

Six RadioButtons aligned as 3 columns and 2 rows in a RadioGroup, so 6 RB-s in RG. If user selects a RB, right under it image1 and text1 are shown and under alternated RB-s image1 and text2 are also shown. User may select any RB. The proper behavior looks like that https://photos.app.goo.gl/NEqTaxsY6daxD3kJA

Image1 is always the same, while text1 and text2 differ. Text1 'You' is shown under the selected RB and text2 'Your friend' - under alternating RB-s.
The quetion still is how to show/hide image1 and text 1 or text 2 alternatively?
I can show/hide image1 and text-s under RB-s which is in the same column, but not alternating RB-s.

Some items from database not being displayed in cardview

I am having a problem with cardview not displaying some from the database.
My app connects to a grails back end which has a PostgreSQL db.
I have a cardview inside a recyclerview. It receives 7 values in form of JSON but on running the app, only 5 are displayed. I try doing System.out of the JSON in the stack trace and I find that all the 7 values are received so everything is okay on that front.
For clarity purposes, the fields that are not being displayed are labs("labs") and drugs administered("drugsAdministered").
Here is the main class(ClinicalHistory.java), the adapter class, the xml and the stack-trace.

I have found the solution. The problem was in the model.
This was my previous model. Note the parameters in the
setDrugs() and setLabs().
public class ClinicalHistory {
String img;
String date;
String labs;
String hospital;
String chiefComplains;
String doctor;
String drugs;
public ClinicalHistory() {
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
public String getHospital() {
return this.hospital = hospital ;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
public String getChiefComplains(){return this.chiefComplains = chiefComplains;}
public void setChiefComplains(String chiefComplains){ this.chiefComplains = chiefComplains;}
public String getLabs() {
return this.labs = labs ;
}
public void setLabs(String hospital) {
this.labs = labs;
}
public String getDoctor() {
return this.doctor = doctor ;
}
public void setDoctor(String doctor) {
this.doctor = doctor;
}
public void setDrugs(String hospital) {
this.drugs = drugs;
}
public String getDrugs() {
return this.drugs = drugs ;
}
public void setDate(String date) {
this.date = date;
}
public String getDate() {
return date;
}
}
After I made this change it worked
public class ClinicalHistory {
String img;
String date;
String labs;
String hospital;
String chiefComplains;
String doctor;
String drugs;
public ClinicalHistory() {
}
public String getImg() {
return img;
}
public void setImg(String img) {
this.img = img;
}
public String getHospital() {
return this.hospital = hospital ;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
public String getChiefComplains(){return this.chiefComplains = chiefComplains;}
public void setChiefComplains(String chiefComplains){ this.chiefComplains = chiefComplains;}
public String getLabs() {
return this.labs = labs ;
}
public void setLabs(String labs) {
this.labs = labs;
}
public String getDoctor() {
return this.doctor = doctor ;
}
public void setDoctor(String doctor) {
this.doctor = doctor;
}
public void setDrugs(String drugs) {
this.drugs = drugs;
}
public String getDrugs() {
return this.drugs = drugs ;
}
public void setDate(String date) {
this.date = date;
}
public String getDate() {
return date;
}

Only first value showing when parsing JSON into Android

More than one value is received but when I am parsing the JSON into Android, it is only showing the first value.
Here is the JsonNew.php file:
require "index.php";
$user_shopID = $_POST["UniqueKey"] ;
$sql_query="Select * from products where ShopID like '$user_shopID';";
$result = mysqli_query($con, $sql_query);
$response = array();
while ($row = mysqli_fetch_array($result))
{
array_push($response,array("ProductID"=>$row[0],"Product Name"=>$row[1], "Buying Price"=>$row[3], "Selling Price"=>$row[4]));
}
echo json_encode(array("server_response"=>$response));
mysqli_close($con);
This is the ContactAdapters.java:
public class ContactAdapter extends ArrayAdapter {
List list = new ArrayList();
public ContactAdapter(#NonNull Context context, #LayoutRes int resource) {
super(context, resource);
}
public void add(Contacts object) {
super.add(object);
list.add(object);
}
#Override
public int getCount() {
return list.size();
}
#Nullable
#Override
public Object getItem(int position) {
return list.get(position);
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
View row;
row = convertView;
ContactHolder contactHolder;
if (row == null) {
LayoutInflater layoutInflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = layoutInflater.inflate(R.layout.row_layout, parent, false);
contactHolder = new ContactHolder();
contactHolder.tx_id = (TextView) row.findViewById(R.id.id);
contactHolder.tx_name = (TextView) row.findViewById(R.id.name);
contactHolder.tx_buy = (TextView) row.findViewById(R.id.buy);
contactHolder.tx_sell = (TextView) row.findViewById(R.id.sell);
row.setTag(contactHolder);
} else {
contactHolder = (ContactHolder) row.getTag();
}
Contacts contacts = (Contacts) this.getItem(position);
contactHolder.tx_id.setText(contacts.getId());
contactHolder.tx_name.setText(contacts.getName());
contactHolder.tx_buy.setText(contacts.getBuy());
contactHolder.tx_sell.setText(contacts.getSell());
return row;
}
static class ContactHolder {
TextView tx_id, tx_name, tx_buy, tx_sell;
}
}
And this the row_layout.xml
android:layout_width="match_parent"

Here is DisplayProductsListview.java

Contacts contacts = new Contacts(id,name,buy,sell);
contactAdapter.add(contacts);
count++;
}
} catch (JSONException e) {
e.printStackTrace();
}
}
Here is the Contacts.java
private String id, name, buy, sell;

public String getBuy() {
return buy;
}
public void setBuy(String buy) {
this.buy = buy;
}
public String getSell() {
return sell;
}
public void setSell(String sell) {
this.sell = sell;
}
}
When I am getting the JSON datas from the server, they are coming perfectly, but when I am making them display in a list view those datas are not coming. Only the first data and his values are coming into the list view.
Here are the Screenshots:
Here you will See what is actually happening with me

In the contactAdapter class you have to create a ArrayList.
ArrayList<Contact> arrayList = new ArrayList<>();
Somewhat you have to do like this.

change this function
while (count<jsonArray.length()){
JSONObject JO = jsonArray.getJSONObject(count);
id = JO.getString("ProductID");
name = JO.getString("Product Name");
buy = JO.getString("Buying Price");
sell = JO.getString("Selling Price");
Contacts contacts = new Contacts(id,name,buy,sell);
contactAdapter.add(contacts);
count++;
}
you have to use jsonarray length not the object length.

Is it my way of calling getFrasa wrong? Or the database cannot be detected? I'm sure I already pushed the database file to both assets folder & inside the package. Sorry, if I'm not formatting the codes correctly. Thanks in advance for any help.

The problem is that you are trying to open the Database from a different location
private static String DB_PATH = "data/data/hairulhazri.malayforyou/databases/";
private static String DB_NAME = "malayforyou";
...
...
db = SQLiteDatabase.openDatabase( DB_PATH + DB_NAME , null, SQLiteDatabase.OPEN_READWRITE);
db is returning NULL because your database is stored in /assets folder not in "data/data/hairulhazri.malayforyou/databases/"
