I'm just trying to add spinners dynamicallyand I found my way here Add Spinner dynamically in a loop
that works good but my issue is the view takes place instead of my original layout (a header, a footer and an image view).
I would like to place it in a specific layout in the xml file, between the header and the footer for example.
Is there a way to do this?
my code
protected void onCreate(Bundle savedInstanceState) {
Intent i = getIntent();
conteneur = "container No : " + i.getStringExtra("container");
conteneur_s = i.getStringExtra("container");
fichano = i.getStringExtra("fichano");
pos = i.getIntExtra("pos", 0);
latitude = i.getDoubleExtra("geolat", 0);
longitude = i.getDoubleExtra("geolon", 0);
volume = i.getStringExtra("volume");
saver = i.getStringExtra("saver");
poids = i.getStringExtra("poids");
tel = i.getStringExtra("telpass");
driver = i.getStringExtra("driverpass");
tour = i.getStringExtra("tour");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_parc);
container = (TextView) findViewById(R.id.nom);
container.setText(conteneur);
RelativeLayout lr = (RelativeLayout) findViewById(R.id.full_layout);
GradientDrawable gd = new GradientDrawable(
GradientDrawable.Orientation.TOP_BOTTOM,
new int[] {0xFFFFFFFF,0xFFB0B0B0});
gd.setCornerRadius(0f);
lr.setBackground(gd);
showImg = (ImageView) findViewById(R.id.imageView1);
String pathparc = Environment.getExternalStorageDirectory() + "/SmartCollecte/PARC/PARAM";
File f = new File(pathparc);
final File file[] = f.listFiles();
LinearLayout layout = new LinearLayout(MAIN_parcActivity.this);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(140, 398);
layoutParams.setMargins(24, 50, 24, 0);
layout.setOrientation(LinearLayout.VERTICAL);
for (int j = 0; j < file.length; j++) {
String[] namewext;
namewext = FilenameUtils.removeExtension(file[j].getName()).split("_");
Toast.makeText(getApplicationContext(),namewext[1],Toast.LENGTH_SHORT).show();
Spinner spinner = new Spinner(getApplicationContext());
String[]choix = new String[]{"choisissez"+j, "Propreté", "Détérioration", "Accès", "Maintenance", "autre"};
List<String> str = new ArrayList<>();
str.add(namewext[1]);
Collections.addAll(str,choix);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(MAIN_parcActivity.this,
android.R.layout.simple_spinner_item, str);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
layout.addView(spinner);
setContentView(layout,layoutParams);
}

I'm not terribly sure here, I wonder if it is replacing the view because you aren't setting a unique ID for each view? That or failing to call layout.invalidate() after finishing a run through the loop.

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
I looked at the questions that look like this, but the answers that were given did not solve my problem. Can you help me?
Java code as:

This is part of my MLX code and the tags are not closed for this reason.
I'm just an beginner.
I'm unable to provide equal space between Item Name and quantity. I want Item Name to occupy space available.
I had tired using setGravity and setColumnStretchable but I'm unable to provide equal space.

in fact I have the following problem:

the problem I think in the ScrollView or something else that flushes to that.
thank you in advance .
You can use this function to display all the items in the listview.
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
Example:
setListViewHeightBasedOnChildren(yourlistview);
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 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...

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.
I recently just overhauled my application to use ListView instead of using the classic TextView.setText and looping the inflation of a layout. I was able to acheive this very well but now I'm having a problem having it fill the screen. Heres the section of my code that does the work.
//Place JSON data into array one item at a time
JSONArray jArray = new JSONArray(result);
//Loop through each record in the database
//Get ListView
ListView lv= (ListView)findViewById(R.id.listview);
// create the grid item mapping
String[] from = new String[] {"lblQuote", "lblBuzzed", "lblShared", "lblSaid", "lblLikes", "lblHates", "lblLocation", "lblDate"};
int[] to = new int[] { R.id.lblQuote, R.id.lblBuzzed, R.id.lblShared, R.id.lblSaid, R.id.lblLikes, R.id.lblHates, R.id.lblLocation, R.id.lblDate };
for(int i=0;i<jArray.length();i++){
Log.i("uDrew Debug", "Made it into JSONArray Loop");
//Get this record
JSONObject json_data = jArray.getJSONObject(i);
//Put each result into variables for later handling
strFName = json_data.getString("FName");
strLInitial = json_data.getString("LInitial");
strCity = json_data.getString("City");
strState = json_data.getString("State");
strDate = json_data.getString("Date");
strQuote = json_data.getString("Quote");
intLikes = Integer.parseInt(json_data.getString("Likes"));
intHates = Integer.parseInt(json_data.getString("Hates"));
strFNameSaid = json_data.getString("FNameSaid");
strLInitialSaid = json_data.getString("LInitialSaid");
intBuzz = Integer.parseInt(json_data.getString("Buzz"));
Log.i("uDrew Debug", "Made it past JSON Parsing");
switch(intBuzz){
case 1:
strBuzzed = ("One Beer\nSyndrome");
break;
case 2:
strBuzzed = ("Buzzed");
break;
case 3:
strBuzzed = ("Drunk");
break;
case 4:
strBuzzed = ("Trashed");
break;
case 5:
strBuzzed = "Retarded";
break;
}
HashMap<String, String> map = new HashMap<String, String>();
map.put("lblQuote", strQuote);
map.put("lblBuzzed", strBuzzed);
map.put("lblShared", strFName + " " + strLInitial);
map.put("lblSaid",strFNameSaid + " " + strLInitialSaid);
map.put("lblDate", strDate);
map.put("lblLocation", strCity + ", " + strState);
map.put("lblLikes", intLikes.toString());
map.put("lblHates", intHates.toString());
fillMaps.add(map);
}//End For loop
// fill in the grid_item layout
SimpleAdapter adapter = new SimpleAdapter(this, fillMaps, R.layout.myviews, from, to);
lv.setAdapter(adapter);

Heres what the App looks like:
There are also no scrollbars and if I change the main.xml ScrolView layout_height="fill_parent" it extends to the end of the screen but the scrollable option isn't there.
Use android:layout_height="fill_parent" in your ScrollView and in the first LinearLayout.
Don't wrap the ListView inside a LinearLayout (the one below the divider View). There's absolutely no need for that.
(Optional) you might want to move the AdView outside the ScollView so it is always visible and not scrolled away
