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;

Getting values of EditTexts from multiple Layouts in Android not working?

Not asked a question in a while so it's been long overdue!
I am creating an app where job items can be created onClick, with each new row containing a Description(EditText), a Price(EditText) and a button to delete the current row, but I am having trouble when getting the values from the EditText fields when there is more than one row - it just returns the values of the newest row.
Aside from the 'Job List Container', the views are created dynamically so pardon the lack of XML, but the structure of what I am trying to achieve is as follows, where clicking the Add button adds a row (this can be multiple rows) and clicking the submit button takes all of the Description and Price values and processes them (adds the prices and adds the job to the DB):
...and this is the code I've written for it called from the addNewJobRow onClick listener (all together for simplicity):
private void addJobItem() {
//Create a new row container
final LinearLayout jobRowContainer = new LinearLayout(this);
//Create a new EditText for the Description
final EditText description = new EditText(this);
description.setHint("Description...");
description.setLayoutParams(new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
1.0f
));
//Create an EditText for the Price
final EditText price = new EditText(this);
price.setHint("00.00");
//Create a new button to delete the row
Button delete = new Button(this);
delete.setBackgroundColor(Color.RED);
delete.setText("X");
//Add Description, Price and Delete to the row container
jobRowContainer.addView(description);
jobRowContainer.addView(price);
jobRowContainer.addView(delete);
//Add the Row Container to the Jobs List Container
ll_jobListContainer.addView(jobRowContainer);
//Get the values of the Description and Price, for each row
btn_JobSubmit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for (int i = 0; i < ll_jobListContainer.getChildCount(); i++) {
for(int j = 0; j < jobRowContainer.getChildCount(); j++) {
if (jobRowContainer.getChildAt(i) instanceof EditText){
String descriptionString = description.getText().toString();
String priceString = price.getText().toString();
System.out.println("z! " + descriptionString + " # " + priceString);
}
}
}
}
});
}
I have tried a couple of iterations of this with and without the nested FOR loops and with and without the use of instanceof, but all it does is print out the newest row.
So, if I have multiple job rows, how can I get all of the values as required?
Thanks for your time and all that nice stuff xxx

The basic problem is that you're using only the last instance of description and price instead of each rows instance. (This may be what Dmitry is saying as well). To fix it, you need to get the input for each row. Here's one way.
Set an ID for description & price. (You can't just use '1' or '2', it needs to be a resource type ID so it is guaranteed to be unique). I made a dummy layout file of a row & assigned IDs in that to the 2 EditTexts. There may be a better way to do it. So anyway, add these 2 lines in your declarations
descripton.setId(R.id.description); and price.setId(R.id.price);
Now this is your onClick()
public void onClick(View v) {
for (int i = 0; i < ll_jobListContainer.getChildCount(); i++) {
LinearLayout currentRow = (LinearLayout)ll_jobListContainer.getChildAt(i);
EditText editText = (EditText)currentRow.findViewById(R.id.description);
String descriptionString = editText.getText().toString();
editText = (EditText)currentRow.findViewById(R.id.price);
String priceString = editText.getText().toString();
Log.d(TAG, "z! " + descriptionString + " # " + priceString);
}
}
EDIT: I didn't want to change this answer since it had already been accepted so I've put a more concise solution in another answer.

Of cause, your last setOnClickListener takes strings
String descriptionString = description.getText().toString();
String priceString = price.getText().toString();
Where description and price - is fields in the function (last edittexts).
The good way to do that is to use RecyclerView/ListView, in "onTextChangeListner" of ViewHolder save new text to model of this object and print all text from your models, not directly from views.

I normally try to answer only question that was asked rather than change code that's not necessary. However, in this case, since I had created a dummy layout just to get Resource IDs, I wonder if that layout file could be put to use. I had started to change my answer but original one was accepted before I could make the changes. I've put a different version of the solution here. I didn't want to modify an answer that had already been accepted.
private void addJobItem() {
//Create a new row container
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout jobRowContainer = (LinearLayout)inflater.inflate(R.layout.row_layout, null);
//Add the Row Container to the Jobs List Container
ll_jobListContainer.addView(jobRowContainer);
//Get the values of the Description and Price, for each row
btn_JobSubmit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for (int i = 0; i < ll_jobListContainer.getChildCount(); i++) {
LinearLayout currentRow = (LinearLayout)ll_jobListContainer.getChildAt(i);
EditText editText = (EditText)currentRow.findViewById(R.id.description);
String descriptionString = editText.getText().toString();
editText = (EditText)currentRow.findViewById(R.id.price);
String priceString = editText.getText().toString();
Log.d(TAG, "z! " + descriptionString + " # " + priceString);
}
}
});
}

Android: Having trouble with newline in TextView inside BaseAdapter

Basically I am inserting text along with new line character in mysql db like this:
$message = 'Hello World' . "\n";
$message .= 'This is a test' . "\n";
$message .= 'Thanks;
When saving message in db, I have tried setting value of new line as \n, \\n, \\\n, \\\\n and even <br> instead of \n then used fromHtml on android app but nothing working out.
In db, I can see there is new line.
On Android app I want to have new line character if any showed in TextView, I have tried various things but nothing is working, I've tried things like:
String message = m.getMessage().toString();
message = message.replaceAll("\\n",
System.getProperty("line.separator"));
Here instead of "\\n", I have also tried "\\\n", "\n" and even "\\\\n"
And:
Spanned html = Html.fromHtml(m.getMessage());
And:
message.replaceAll("\n","<br />");
message.replaceAll("\r\n","<br />");
message.replaceAll("\r","<br />");
And:
android:singleLine="false"
With various things tried, in TextView I get text like these permutations:
Hello WorldThis is a testThanks
Hello World\This is a test\Thanks
Hello World\nThis is a test\nThanks
Here is my complete code:
public class MessageListAdapter extends BaseAdapter {
private Context context;
private List<ListMessage> messagesItems;
public MessageListAdapter(Context context, List<ListMessage> navDrawerItems) {
this.context = context;
this.messagesItems = navDrawerItems;

#SuppressLint("InflateParams")

/**

ListMessage m = messagesItems.get(position);
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
// Identifying the message owner
if (messagesItems.get(position).isSelf()) {

convertView = mInflater.inflate(R.layout.list_item_message_right,
null);

lblFrom.setText(m.getFromName());
// Spanned html = Html.fromHtml(m.getMessage());
// String message = html.toString();
String message = m.getMessage().toString();
message = message.replaceAll("\\n",
System.getProperty("line.separator"));
try {
lblTo.setText(message);
} catch (Exception e) {
lblTo.setText(message);
}
return convertView;

Is something wrong with baseAdaptor? Somewhere I saw this link, it suggested SimpleAdapter has problem setting html but in my case this doesn't help either since I am using BaseAdapter.
I will be really realy thankful for your help as I have wasted five hours on this new line issue :(

Try:
message = message.replaceAll("\\n", "
");
or (only if there really are double backslashes in the input)
message = message.replaceAll("\\n", "
");
Update: Replacements were not working as the search string (\n) had been stripped out (escaped) by the sql database. This answer supplied a workaround which involves running unescape on the string prior to setting it on the TextView.

Listview only filling with first item

I have a Listview that gets its contents from an async task, but only the first item is actually getting placed into the Listview.

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.

Creating a New Button in existing Source Code? [closed]

Im using his source code but it seems very different than the "Beginner Level" Programming I have been use to i.e. creating new project, modifying layout, referencing in main.java, etc.
I'm trying to use his source code and modify/create new operations and maybe add a activity. I would usually know how to do most of that stuff if it wasn't laid out differently. Thank You!

I have a great answer for you. I recently wanted to create my own button in android but I wanted to do it in a simple way. Follow these steps and in a few minutes I will post pictures.
1) create a new layout. start with a LinearLayout. Nest a FramedLayout and another LinearLayout inside of it.
2) then add a TextView to it. This is where practice makes perfect. Play around with the attributes. Learn what they do. when you have the general information of how you want your button to be display go to the next step.
3) what your are going to do is include this in another view as a button. You can use a specific attribute to make it look like a button as well.
Give me a few minutes and I will post some code and a picture.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/CBN_LinearLayout"
style="#android:style/Widget.Button"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/CBV_texview1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginRight="10dp"
android:layout_weight="1"
android:gravity="right"
android:text="#string/checkorder"
android:textColor="#color/Black" />
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1" >
<ImageView
android:id="#+id/CBV_imageView1"
android:layout_width="23dp"
android:layout_height="15dp"
android:layout_gravity="center_vertical"
android:contentDescription="#string/redcirclenotify"
android:src="#drawable/rednotify"
android:visibility="visible" />
<TextView
android:id="#+id/CBV_textview2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="8dp"
android:gravity="left"
android:text="#string/zero"
android:visibility="visible" />
</FrameLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/CBV_textview3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fadingEdge="horizontal"
android:gravity="center_horizontal"
android:text="#string/blankstring" />
<TextView
android:id="#+id/CBV_textview4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:text="#string/blankstring" />
</LinearLayout>
when you add it to another view as a button you use:
<include
android:id="#+id/MI_checkorder"
style="android:buttonStyle"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_gravity="bottom"
android:layout_marginTop="5dp"
android:layout_weight="1"
layout="#layout/custombtnview"
android:background="#style/AppTheme"
android:clickable="true"
android:focusable="true" />
The important part of this is setting the Style for the root LinearLayout to #android:style/Widget.Button
Once this is done it will look like a button and work like a button.
Below is an image of the final product:
another part of your question. Adjust sizes of standard buttons in android:
1) almost everything can be controled with how you use the XML. This can all be controled in the area to right, in the ADK. These attributes help you to control almost every aspect.
for example as in the calculator...
you have 4 buttons in a row so you want to add 4 buttons inside of a horizontal LinearLayout. Then you can give the a weight of 1 for each button then set their Width to FillParent. This will auto size the buttons to be displayed in the width of the screen equally.
Am I better off making my own calc or modify the existing code?
I would never tell someone to recreate the wheel, however, if you do not understand the code well enough to pickup where they left off then this can be an uphill struggle for you. Your best bet if you are having trouble understanding the code given to you or how to modify it, would be to actually post the code in another question and be very specific and ask for example how can I change what this particular button displays and what the result of clicking it would be. This forum depends on the people asking the questions to be clear and concise. If not then questions will closed as fast as they are opened. Generalizations are severely frowned upon on the site.
In the end, what I am trying to do is make my own scientific calculator but I don't want to spend extra time doing the simple operations.
The best way to answer this is to take a look at how the calculator is assembled in the GUI or Graphical Layout. Try changing a button and what it does. for example make the plus a minus just for the learning curve.
1) look for , PLUS(" + ",KeypadButtonCategory.OPERATOR) and notice that is a string for plus. change it to " T " see if it changes in the app. If it does then go into the code. In the code you will find case CALCULATE: for for the = sign in the ENUM and then inside that you find evalResult = evaluateResult(true);. If you follow this you reach:
if (operator.equals(KeypadButton.DIV.getText())) {
result = leftVal / rightVal;
} else if (operator.equals(KeypadButton.MULTIPLY.getText())) {
result = leftVal * rightVal;
} else if (operator.equals(KeypadButton.PLUS.getText())) {
result = leftVal + rightVal;
} else if (operator.equals(KeypadButton.MINUS.getText())) {
result = leftVal - rightVal;
}
so now you can change result = leftVal + rightVal; to result = leftVal - rightVal; and you have just changed it. so it will take some time to understand the code but you have to do some trial and error to understand it. I hope this helps answer your question.
