how to add value to each item of string array in string.xml in spinner

i have a problem here in using spinner, i want to add value to each array item in my string.xml
this is my code:
<string-array name="hubungan">
<item>Choice</item>
<item>CHILD</item>
<item>PARENT</item>
<item>HUSBAND</item>
<item>WIFE</item>
</string-array>
I mean is:
<string-array name="hubungan">
<item>Choice value="1"</item>
<item>CHILD value="2"</item>
<item>PARENT value="3"</item>
<item>HUSBAND value="4"</item>
<item>WIFE value="5"</item>
</string-array>

try this
<Spinner
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/spinner"
android:entries="#array/hubungan"
/>

Well if you insist doing in this way try this example. The example will be as minimal as possible since you don't provide enough code.
Your string array values as you defined but I modified the way of storing by convenince.
<string-array name="hubungan">
<item>Choice,1</item>
<item>CHILD,2</item>
<item>PARENT,3</item>
<item>HUSBAND,4</item>
<item>WIFE,5</item>
</string-array>
I will assume that you have a spinner and a textview in your activity / fragment. You can set this data and process it as needed like following:
Spinner definition in xml
<Spinner
android:id="#+id/spinner"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
This code must be located in your onCreate method if you use an activity, or onViewCreated method if you use a fragment.
// I assume that you've already instantiated the spinner and textview
// Setup for spinner
String[] hubungans = getResources().getStringArray(R.array.hubungan);
if(hubungans != null && hubungans.length > 0) {
String[] names = new String[hubungans.length];
String[] values = new String[hubungans.length];
// Now we will parse the records and split them into name and value
for(int i = 0; i < hubungans.length; i++) {
String hubungan = hubungans[i];
if(hubungan == null || hubungan.isEmpty()) {
Log.d(TAG, "onViewCreated: couldn't get record for index "+i);
continue;
}
// Split the record by "," seperator for example for choice "Choice,1"
String[] nameValue = hubungan.split(",");
if(nameValue.length < 2) {
Log.d(TAG, "onViewCreated: couldn't get split record for index "+i);
continue;
}
names[i] = nameValue[0]; // first index will have the names
values[i] = nameValue[1]; // second will have its value
}
Log.d(TAG, "onViewCreated: names and values: "+ Arrays.toString(names)+" - "+Arrays.toString(values));
ArrayAdapter<CharSequence> adapter = new ArrayAdapter<>(requireContext(), android.R.layout.simple_spinner_item, names);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
int val = 0;
try {
val = Integer.parseInt(values[position]); // Here you have value as numeric type
} catch (NumberFormatException nfe) {
nfe.printStackTrace();
}
textView.setText(String.format("Value for %s is %d", names[position], val));
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
} else {
Log.d(TAG, "onViewCreated: Hubungans cannot be read!");
}
There you go! Hope this helps you with your unique problem.

TextView not updated

I have a text view that is supposed to change as some checkboxes are clicked. A user has a certain amount of free points with which to purchase attributes. When a checkbox is clicked the points are decreased. When a checkbox is unchecked, the points it cost to check it are supposed to be refunded to the total free points, but that's not the case in the current code that I have. The code for the checkboxes is straightforward:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/class_container"
android:layout_below="#id/stats_container"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/class_select"
android:textSize="24sp"
android:id="#+id/class_description"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"/>
<CheckBox
android:layout_below="#id/class_description"
android:id="#+id/checkbox_noble"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/class_noble"
android:onClick="creationClassClick"/>
<CheckBox
android:layout_below="#id/class_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/checkbox_warrior"
android:text="#string/class_warrior"
android:layout_toEndOf="#+id/checkbox_noble"
android:layout_toRightOf="#+id/checkbox_noble"
android:onClick="creationClassClick"/>
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/checkbox_wizard"
android:text="#string/class_wizard"
android:layout_below="#+id/checkbox_noble"
android:onClick="creationClassClick"/>
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/checkbox_trader"
android:text="#string/class_trader"
android:layout_below="#id/checkbox_warrior"
android:layout_toEndOf="#+id/checkbox_wizard"
android:layout_toRightOf="#+id/checkbox_wizard"
android:onClick="creationClassClick"/>
</RelativeLayout>
The relevant methods here are as follows:
public void pointChange(final int amt){
Runnable updateTextView = new Runnable() {
#Override
public void run() {
TextView tv = findViewById(R.id.free_points);
tv.setText(String.valueOf(amt));
}
};
runOnUiThread(updateTextView);
}
public void creationClassClick(View v){
int freePoints = Integer.parseInt(freePts.getText().toString());
if(lastPointsUsed > 0){
int addedBack = freePoints + lastPointsUsed;
pointChange(addedBack);
freePoints = Integer.parseInt(freePts.getText().toString());
lastPointsUsed = 0;
}
String targetFull = A.getResources().getResourceEntryName(v.getId());
String[] target = targetFull.split("_");
boolean query;
int cost = 1;
int error;
int cause;
switch(target[1]){
case "noble":
warriorCheck.setChecked(false);
wizardCheck.setChecked(false);
traderCheck.setChecked(false);
cost = 12;
break;
case "warrior":
wizardCheck.setChecked(false);
nobleCheck.setChecked(false);
traderCheck.setChecked(false);
cost = 8;
break;
case "wizard":
warriorCheck.setChecked(false);
nobleCheck.setChecked(false);
traderCheck.setChecked(false);
cost = 9;
break;
case "trader":
warriorCheck.setChecked(false);
wizardCheck.setChecked(false);
nobleCheck.setChecked(false);
cost = 10;
break;
}
lastPointsUsed = cost;
query = (freePoints - cost < 0);
error = R.string.creation_no_points;
cause = freePoints - cost;
if(query){
new Modal(app, true, R.string.oops, error, 0, 0);
}else{
this.classType = target[1];
pointChange(cause);
}
}
When i use the pointChange() method from any other method in this activity, it works fine. Its only when unchecking a checkbox that it fails.
I've searched google and SO for the answer, and the best I could come up with is the runnable set to runonuithread, but it doesn't work either. Any help would be greatly appreciated.
--EDIT--
The appropriate views are retrieved via Butterknife, but this is literally the only code other than the xml that deals with them:
#BindView(R.id.free_points) TextView freePts;
#BindView(R.id.checkbox_noble) CheckBox nobleCheck;
#BindView(R.id.checkbox_warrior) CheckBox warriorCheck;
#BindView(R.id.checkbox_wizard) CheckBox wizardCheck;
#BindView(R.id.checkbox_trader) CheckBox traderCheck;

But it is not showing my last data in my database.
As you can see by my screen shot last data is not showing form database. Why fanta is not showing ? Always last row is showing in alertdialog from database.What is logical issue in my code i can't understand ? Most probably it is mistake of my logic but where it is i can't find . I hope i am able to explain my problem to all my well-wisher . Please help me . Thanks in advance to all

i would like to know why are u passing position -1 as param to movetoPosition method
just pass position ..
i think according to your approach last element is never being read !!

Finally i solve my issue. Thanks to all who suggest me to solve this issue.
public int getCount() {
// TODO Auto-generated method stub
Log.d(TAG, "GetCount "+starterCount);
return starterCount +1 ;
}
And
if ((position !=0)&& (position != starterCount + 1))
{
// TODO Auto-generated method stub
}

Listview only filling with first item

I think you can't see the list properly because your ListVew is within a ScrollView. ListView itself is scrollable , so it doesn't show properly in a ScrollView , you can at most see a ListView with very small height that fits one or two elements. Try using your ListView outside of ScrollView to test whether your code is correct or not. Hope it helps.

The short answer is that your doing it wrong.
You should be asynchronously loading the data into a sqlite db table and using a Loader with a cursor adapter.
Also, even using the code you have (and its hard to read from my phone here) it looks like your only adding one element to the list before you add the list adapter to the list view, which would be why you are only seeing a single item.
Another thing that may be causing you trouble is that you're asynchronously loading the data into a list view that has been created but you don't seem signal that the adapter has new data as the task finishes.

Move your code for the adapter so that it is outside and below your for loop. You are creating a new adapter for every iteration and it is probably running really slow because of it. Also you are setting your onitemclicklistener for every iteration too. It only needs to be done one time.
Do that and then see what happens. Also put a breakpoint after the for loop and see how many items are in your tasteList. If there is more than one then your adapter is most likely the problem.
If you can post your code for your adapter.
I guess my answer is that you probably aren't returning back more than one item. Since the adapter is posting data to the list it should be ok. Once you can debug the app and see how many items are returning then we can know for sure.

How can we use a variable in R.id

The content of xml are
<AbsoluteLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/MainFrame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<AbsoluteLayout
android:id="#+id/AbsoluteLayout1"
android:layout_width="match_parent"
android:layout_height="172dp"
android:layout_x="12dp"
android:layout_y="26dp"
android:visibility="invisible" >
</AbsoluteLayout>
<AbsoluteLayout
android:id="#+id/AbsoluteLayout2"
android:layout_width="match_parent"
android:layout_height="172dp"
android:layout_x="20dp"
android:layout_y="184dp" android:visibility="invisible">
</AbsoluteLayout>
</AbsoluteLayout>
Here's the main code
String layoutid;
int ctr = 1;
AbsoluteLayout [] mainlayout = new AbsoluteLayout[12];
while (ctr<3)
{
layoutid = "AbsoluteLayout" + ctr;
mainlayout[ctr] = (AbsoluteLayout)findViewById(R.id.layoutid);
ctr++;
}
We need to make a loop to make
ctr = 1
AbsoluteLayout + ctr = AbsoluteLayout1
ctr++;
AbsoluteLayout + ctr = AbsoluteLayout2
we want to declare the AbsoluteLayout1 and AbsouluteLayout2 but it doesn't work. We know that the R.id.layoutid is the culprit. So how can we resolve it?

I solved it using getIdentifier method
Button[] buttons;
for(int i=0; i<buttons.length; i++) {
{
String buttonID = "sound" + (i+1);
int resID = getResources().getIdentifier(buttonID, "id", getPackageName());
buttons[i] = ((Button) findViewById(resID));
buttons[i].setOnClickListener(this);
}

the id is an intiger value not string:
hope u ll get an idea from below code
while (ctr<3)
{
int layoutid;
if(ctr==1)
{ layoutid = R.id.AbsoluteLayout1;}
else{
layoutid = R.id.AbsoluteLayout2;}
mainlayout[ctr] = (AbsoluteLayout)findViewById(layoutid);
ctr++;
}
---------------------------------------------
all these won post an error as they are handled as int itself manipulate as you want you cant use this as it is as
int[] ctra={R.id.xx,R.id.xxx};
int i=0;
while (ctr<3)
{
mainlayout[i]=(AbsoluteLayout)findViewById(ctra[i]);
i++;}
