linear layout java and xml

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);

GradientDrawable.Orientation.TOP_BOTTOM,

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();

layoutParams.setMargins(24, 50, 24, 0);

for (int j = 0; j < file.length; j++) {
String[] namewext;
namewext = FilenameUtils.removeExtension(file[j].getName()).split("_");

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.

Increasing scrollview by adding buttons in a relativelayout (or linearlayout ) from bottom to top

Could really use some help with this one.
I'm trying to start with a single button at the bottom of my screen. When my counter++ button is clicked, a second button will be dynamically created above the button at the bottom of the screen. I was able to get this far, the problem is that the height of my scrollview doesn't increase when my buttons reach the top of the screen. Please see my example below.
Example
I'm assuming the scrollview only increases when items are added below the current view although if that's the case, is there no way I can create several buttons starting at the bottom going upwards?
Here my code.
XML:
<RelativeLayout 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="wrap_content"
android:layout_height="wrap_content"
tools:context="com.example.bbetzner.ttt.Map">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<RelativeLayout
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="#+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="count++"
/>
<Button
android:id="#+id/floor0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="0"
/>
</RelativeLayout>
</ScrollView>
</RelativeLayout>
Java:
public void addfloor(){
Button myButton = new Button(this);
myButton.setText(""+floor);
margincount += 100;
RelativeLayout ll = findViewById(R.id.layout);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ABOVE, R.id.floor0);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
lp.bottomMargin = margincount;
ll.addView(myButton, lp);
}
I've also tried doing this in a linear layout to see if the scrollview would increase but I couldn't figure out how to stack buttons from bottom to top in a linear layout. :S
Thanks in advance, yall are awesome!

#Texas use below code using that you are achieving what you want:
<RelativeLayout 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="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<Button
android:id="#+id/count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="count++" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="vertical">
<LinearLayout
android:id="#+id/lladdViews"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="bottom"
android:orientation="vertical">
<Button
android:id="#+id/floor0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="0" />
</LinearLayout>
</ScrollView>
</LinearLayout>
and here is Java File:
public class SampleActivity extends Activity {
LinearLayout lladdViews;
Button count;
int floor = 0;
private int margincount = 0;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.sample_activity);
lladdViews = (LinearLayout) findViewById(R.id.lladdViews);
count = (Button) findViewById(R.id.count);
count.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addfloor();
}
});
}
public void addfloor() {
Button myButton = new Button(this);
myButton.setText("" + floor);
margincount += 10;
RelativeLayout ll = new RelativeLayout(this);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.ABOVE, R.id.floor0);
lp.addRule(RelativeLayout.CENTER_HORIZONTAL);
lp.bottomMargin = margincount;
ll.addView(myButton, lp);
lladdViews.addView(ll);
}
}

Rating bar shows more stars when I rotate my application

I have this weird issue with my rating bar stars.

// looping through all rows and adding to list

RatingBar rb3 = (RatingBar) findViewById(R.id.rb3);
rb3.setRating(fourthRating);
I get the rating values from database file and everything works fine , the stars are ok but when I rotate the phone they are all wrong. I know that when u rotate your phone the current activity gets loaded again, but it's the same code and it loads wrong. Maybe it's multiplying the stars.. I may sound funny but I have no idea what is going wrong. Someone please give me a lead..

I found out the problem !
android:shrinkColumns="1,0" android:stretchColumns="0,1"
Setting this to the TableLayout caused this strange issue.
Thanks everyone for your interest in helping me ..

RadioButton switching between layouts

So I would like to have a calculator in my app. User will first click on RadioButton which would be for Imperial and Metric units, and depending on which one does user click, one of the layouts would appear.
As you know imperial units has feets and inches, for which I need two EditTexts, but metric unit needs only one.
So that's what I want, switching between layouts in same activity to avoid using fragments.
Any ideas?

Note that I solved blank space problem with setting visibility to GONE, but when I open activity both EditTexts appear, imperial and metric. I want them both to be invisible until user selects one RadioButton

To define the click event handler for a button, add the android:onClick attribute to the <RadioButton> element in your XML layout. The value for this attribute must be the name of the method you want to call in response to a click event. The Activity hosting the layout must then implement the corresponding method.
For example, here are a couple RadioButton objects:
<?xml version="1.0" encoding="utf-8"?>
<RadioGroup xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<RadioButton android:id="#+id/radio_pirates"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/pirates"
android:onClick="onRadioButtonClicked"/>
<RadioButton android:id="#+id/radio_ninjas"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/ninjas"
android:onClick="onRadioButtonClicked"/>
</RadioGroup>
Within the Activity that hosts this layout, the following method handles the click event for both radio buttons:
public void onRadioButtonClicked(View view) {
// Is the button now checked?
boolean checked = ((RadioButton) view).isChecked();
// Check which radio button was clicked
switch(view.getId()) {
case R.id.imperial:
if (checked)
EditBox1.setVisibility(Visible)
break;
case R.id.metrics:
if (checked){
EditBox1.setVisibility(Visible)
EditBox2.setVisibility(Visible)
}
break;
}
}

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.
