Increasing or decreasing the item in Listview Android

I am using android studio. Code Java. I bring the data in the json file to listview. When I press the increase and decrease button, I want to bring it to the textview. I just want to increase or decrease the number of products I click. I couldn't access the buttons and textview inside the listview. How can I do it?
try {
JSONObject obj=new JSONObject(LoadFromJsonAssets());
Resources resources = context.getResources();
JSONArray array =obj.getJSONArray("domestic");
HashMap<String,String> list;
ArrayList<HashMap<String,String>> arrayList=new ArrayList<>();
for (int i=0;i<array.length();i++){
JSONObject o=array.getJSONObject(i);
String productName=o.getString("productName");
String productPrice=o.getString("productPrice");
String productPic=o.getString("productPic");
final int resourceId = resources.getIdentifier(productPic, "drawable", context.getPackageName());
Drawable drawable = resources.getDrawable(resourceId);
Bitmap bitmap = BitmapFactory.decodeResource(context.getResources(), resourceId);
list= new HashMap<>();
list.put("productName",productName);
list.put("productPrice",productPrice);
list.put("productPic",Integer.toString(resourceId) );
arrayList.add(list);
}
final ListAdapter adapter= new SimpleAdapter(this,arrayList,R.layout.list_view_design,new String[]{"productName","productPrice","productPic"},new int[]{R.id.productName,R.id.productPrice,R.id.productPic});
listView.setAdapter(adapter);
listview design:

Sorry but I cannot comment. Does the below not work?
Find it by:
final TextView textViewCounter = (TextView) rowView.findViewById(R.id.counterrrr);
and then set the text as needed:
// could be wrongly typed, just from the top of my head.
String currentCount = textViewCounter.getText();
int newCount = Integer.parseInt(currentCount) +/- 1;
textViewCounter.setText(String.valueOf(newCount));

android.widget.RelativeLayout cannot be cast to androidx.recyclerview.widget.RecyclerView

I wrote a little code, but I had a problem. Error that I encounter as: android.widget.RelativeLayout cannot be cast to androidx.recyclerview.widget.RecyclerView

Android - How do I expand the height of a view from bottom to top?

I'm trying to make a visualization of some data in Android using a vertical bar chart, but when I increase or decrease the height of a View programatically by clicking a button, it changes from top to bottom, as in the image below (default value is 300).
How do I change the height from bottom to top, ie keeping the base of the view fixed?
Expected result:

My JAVA codes:
public class UpdateActivity extends BaseActivity {
#BindView(R.id.dialogEndCount_buttonsLay)
LinearLayout dialogEndCount_buttonsLay;
private Window window;
private Activity activity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_update);
//Initialize
ButterKnife.bind(this);
activity = this;
window = activity.getWindow();
//Set color to statusBar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.setStatusBarColor(getResources().getColor(R.color.tabHomeColor));
}
//Set dynamically weight
dialogEndCount_buttonsLay.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
}
}
How can I fix this problem?

If you want set dynamically weightSum just use this code :
dialogEndCount_buttonsLay.setWeightSum(3f);
i hope help you

You're mixing LinearLayout and RelativeLayout. Change your layout to use a LinearLayout then weight is an available property on your LayoutParams.
val params = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
params.weight = 1f

Inflated items are gone when device orientation changes

Hi i'm using eclipse for deveoping this android app. I'm inflating a layout using inflator and everything works fine.. I'm adding those inflated items one by one to another layout, so when the device's orientation is changed, all those inflated items are gone. The application seems like it has been restarted. But some values are still remaining.. Please help..
public void addNewItem() {
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View item = li.inflate(R.layout.activity_order_items, null);
orderItemFrameView.add(item);
itemsLayout.addView(item);
setAdditionalFonts(item);
}
private void setAdditionalFonts(View view) {
TextView lblNameTak = (TextView)view.findViewById(R.id.tak_itemNo);
AutoCompleteTextView txtNameTak = (AutoCompleteTextView)view.findViewById(R.id.tak_itemName);
ImageView barScan = (ImageView)view.findViewById(R.id.barcode_scan);
TextView lblRate = (TextView)view.findViewById(R.id.tak_lblRate);
TextView lblQty = (TextView)view.findViewById(R.id.tak_lblQty);
TextView lblTotal = (TextView)view.findViewById(R.id.tak_lblTotal);
TextView rate = (TextView)view.findViewById(R.id.tak_Rate);
EditText2 qty = (EditText2)view.findViewById(R.id.tak_Qty);
TextView total = (TextView)view.findViewById(R.id.tak_Total);
qty.totTextView = total;
qty.rateTextView = rate;
qty.orderTake = this;
qty.index = orderItemFrameView.size() - 1;
qty.sqlDb = SqlDb;
qty.itemName = txtNameTak;
setupBarcodeScan(barScan);
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/ubuntu-l.ttf");
Typeface tf2 = Typeface.createFromAsset(getAssets(), "fonts/calibri.ttf");
Typeface tf3 = Typeface.createFromAsset(getAssets(), "fonts/ubu-r.ttf");
Typeface tf4 = Typeface.createFromAsset(getAssets(), "fonts/tahoma.ttf");
lblNameTak.setTypeface(tf3);
txtNameTak.setTypeface(tf2);
lblRate.setTypeface(tf2);
lblQty.setTypeface(tf2);
lblTotal.setTypeface(tf2);
lblNameTak.setText("Item " + (qty.index + 1));
DbAdapterItem dbItem;
TextAdapterItem txtItem;
dbItem = new DbAdapterItem(this, SqlDb);
txtItem = new TextAdapterItem(dbItem, this, qty);
txtNameTak.setAdapter(txtItem);
txtNameTak.setOnItemClickListener(txtItem);
txtNameTak.requestFocus();
}
all these items created by addNewItem() are vanished...
here is the layout from which i'm inflating...

It's normal behaviour and you are correct. the activity is recreated from scratch on rotation.
If you want something to persist. store it during onSaveInstanceState in the provided bundle.
then during onCreate check to see if the bundle is null, if it isn't, pull your data out and add the view elements again.
Alternatively you can fudge it and state in the manifest that your activity will handle orientation/configuration changes.
