How do I identify buttons right inside Java Activity Class?

I designed two buttons b1,b2 inside "KeyboardService.java" which should update the value of PACK_LIB inside "Stickers.java".
Three files attached:
main_board_layout.xml
Stickers.java
KeyboardService.java
I assigned both buttons with IDs of Button1 = b1 and Button2 = b2.
The built is successful but when I click on the buttons both do not work.
I think it is maybe a problem with this line ->
final Button button1 = (Button) mainBoard.findViewById(R.id.b1);
Because the Buttons are inside a FrameLayout. But when I use ID of that it won't work either.
Any ideas?

Dynamic number of LinearLayouts in Android Studio

In my android app I want to display a HorizontalScrollView with a dynamic number of images. Currently I have to build a LinearLayout for each Image. Is there a way to do it dynamically with a list of URLs and appropriate the quantity of LinearLayouts of the length of this list?

Can you help me?

The correct way to solve this error would be using a RecyclerView along with an Adapter.
Recyclerview was built specifically for this task where you have a dynamic number of items which you want to be displayed on your screen.

hide layout checkbox is checked android

I am trying to simply hide a linear layout if a checkbox is clicked. I have defined function and onClick attribute calls it which is also tested with toast but when I try hiding the layout, it doesn't do anything.
The layout.xml:
<CheckBox
android:id="#+id/cbguest"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.9"
android:onClick="itemClicked"
/>
In MainActivity.java
int[] i = {0};
public void itemClicked(View v) {
LinearLayout layoutguest1 = (LinearLayout) findViewById(R.id.guestlayout);
if (lns[0]%2 == 0) {
Toast.makeText(getApplicationContext(),"Visible", Toast.LENGTH_SHORT).show();
layoutguest1.setVisibility(View.VISIBLE);
lns[0]+=1;
}
if (lns[0]%2 != 0) {
layoutguest1.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(),"Gone", Toast.LENGTH_SHORT).show();
lns[0]+=1;
}
}

**MainActivity.java
put this code in MainActivity.java file**
public class MainActivity extends Activity {
private LinearLayout layoutLogin;
private CheckBox chkBox;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
chkBox = (CheckBox) findViewById(R.id.chkBox);
layoutLogin = (LinearLayout) findViewById(R.id.layoutLogin);
chkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked)
{
// TODO Auto-generated method stub
if(isChecked)
{
layoutLogin.setVisibility(View.GONE);
chkBox.setText("UnHide");
}
else
{
layoutLogin.setVisibility(View.VISIBLE);
chkBox.setText("Hide");
}
}
});
}
}

You should be using onCheckedChangeListener as I don't think it registers as an onClick- but an onCheck.

Get values from Dynamic list

Good day everyone,
I'm learning Android development and I try to build some dynamic lists for my application. And I'm stuck... like for 4 hours already.
I have two layouts:
1. main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/action_buttons"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:gravity="center"
>
<Button
android:id="#+id/button_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_calculate" />
<Button
android:id="#+id/button_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/button_count"
android:text="#string/button_add" />
</LinearLayout>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/action_buttons"
>
<LinearLayout
android:id="#+id/action_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</RelativeLayout>
action_list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/action_list_item_root"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/action_list_item_edittext_drinkName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/action_list_item_button_remove"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/action_list_item_title"
android:padding="10dp" />
<EditText
android:id="#+id/action_list_item_edittext_drinkPercent"
android:text="40"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/action_list_item_edittext_drinkAmount"
android:inputType="number"
android:padding="10dp"/>
<EditText
android:id="#+id/action_list_item_edittext_drinkAmount"
android:text="0.0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/action_list_item_button_remove"
android:layout_alignBottom="#+id/action_list_item_button_remove"
android:inputType="numberDecimal"
android:width="50dp"
android:padding="10dp" />
<Button
android:id="#+id/action_list_item_button_remove"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="#string/action_list_item_button_remove" />
And code that creates dynamic list:
public class MainActivity extends Activity {
LinearLayout actionList = null;
private Button btnAdd;
private Button btnCalculate;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initActivityElements();
}
private void initActivityElements() {
initAddButton();
initCalculateButton();
}
private void initCalculateButton() {
btnCalculate = (Button) findViewById(R.id.button_count);
btnCalculate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView amount = (TextView) findViewById(R.id.action_list_item_edittext_drinkAmount);
//this retrives TextView value from first list
Toast.makeText(getApplicationContext(), amount.getText().toString(),
Toast.LENGTH_SHORT)
.show();
}
});
}
private void initAddButton() {
actionList = (LinearLayout) findViewById(R.id.action_list);
btnAdd = (Button) findViewById(R.id.button_add);
btnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RelativeLayout listItem = (RelativeLayout) View.inflate(
MainActivity.this, R.layout.action_list_item, null);
TextView name = (TextView) listItem
.findViewById(R.id.action_list_item_edittext_drinkName);
name.setText("Here is the Title " + actionList.getChildCount());
listItem.findViewById(R.id.action_list_item_button_remove)
.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
actionList.removeView((View) v.getParent());
}
});
actionList.addView(listItem);
}
});
}
My problem is that I need to get all data from TextView boxes (Amount, Percent), but I can retrive that data only from first item of a list (look at onClickListener for btnCalculate) and can't figure out how to do it, but tried to add 'unique ids' for view (but that brakes layout, badly), tried setting Tags but again with no luck.
Maybe anyone can give a tip? I bet there is some easy way to do it, but I'm failing to find it and google is no help here.
Thanks

I'm not really sure what exactly you are trying to do but it sounds like you are trying to take in information and populate it into a view. I would recommend having a static text box that takes in your information and builds that into a listview. A good example of how to do that is located here http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html.

dynamic checkbox creation

I am wanting to create a set of checkboxes dynamically during run time in my android application. When the application runs nothing shows up except the button. What am i forgetting? Thanks in advance!
public class DataNotificationSurvey extends Activity {
private Date timeStamp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.datanotifylayout);
final Button notifySubmitButton = (Button) findViewById(R.id.notifySubmitButton);
TableLayout t1 = (TableLayout)findViewById(R.id.notificationTableLayout);
for(int i = 0; i < 5; i++) {
TableRow tr = new TableRow(this);
CheckBox chk = new CheckBox(this);
chk.setText(Integer.toString(i));
tr.addView(chk);
t1.addView(tr);
}
notifySubmitButton.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
}
//My xml layout, will be changing this later to the one posted below to see if it works.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="#+id/notificationLinearLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TableLayout
android:id="#+id/notificationTableLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableRow
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:text="Static Button"/>
</TableRow>
</TableLayout>
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/notifySubmitButton"
android:text="Submit"></Button>
</LinearLayout>

This works fine for me.
public class DynamicTableRowWithCheckBox extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final Button notifySubmitButton = (Button) findViewById(R.id.myButton);
TableLayout table = (TableLayout) findViewById(R.id.myTable);
for (int i = 0; i < 3; i++)
{
TableRow row = new TableRow(this);
CheckBox chk = new CheckBox(this);
chk.setText(Integer.toString(i));
row.addView(chk);
table.addView(row);
}
notifySubmitButton.setOnClickListener(
new View.OnClickListener()
{
#Override
public void onClick(View v)
{
finish();
}
});
}
}
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello" />
<Button
android:id="#+id/myButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Close" />
<TableLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:id="#+id/myTable" />
</LinearLayout>

Change your XML to:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="#+id/notificationLinearLayout"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TableLayout
android:id="#+id/notificationTableLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableRow>
<Button
android:text="Static Button" />
</TableRow>
</TableLayout>
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/notifySubmitButton"
android:text="Submit"></Button>
</LinearLayout>
This removes the layout_height of your TableLayout to wrap_content, and it removes the height and width settings of your TableRow, because, "The children of a TableRow do not need to specify the layout_width and layout_height attributes in the XML file. TableRow always enforces those values to be respectively MATCH_PARENT and WRAP_CONTENT."
