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?

How to put scrollview in a alertdialog programmatically

I have a problem to display all data in a AlertDialog where the data just last records displayed. I tried adding a scrollview in a AlertDialog but scrollview doesn't show and still last records displayed which actually the qty all data more than 13rd rows.

String Price = String.valueOf(list.getPrice());
String file = list.getFile();
final TextView txtId = (TextView) view2.findViewById(R.id.txtId);
txtId.setText(id);
final TextView txtItem_name = (TextView) view2.findViewById(R.id.txtItem_name);
txtItem_name.setText(Item_name);

Get value of a EditText in another layout

I have an dialog that appears where the user can costumize how many points they get from each action. The dialog is based on a layout that is not the main_activity. the main activity is the layout that is used in setContentView in the onCreate method.
when I try to get the values I am only getting null, (because the layout where the EditText is is not set as the contentview.... maybe?)
How do I solve this problem so that I get the value of the edittext in the "settings" layout and can use that value in the MainActivity?

I would strongly recommend using SharedPreferences. This way, you can access the data even if you restart your application. If that does not work for you, you can use Intent.
Consider reading this StackOverflow post.
Using SharedPreferences:
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(getString(R.string.points), pointsPerActivity);
editor.commit();
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
int defaultValue = 1;
// or you can store the value somewhere
// getResources().getInteger(R.integer.defaultPointsPerActivity);
int pointsPerActivity = sharedPref.getInt(pointsPerActivity, defaultValue);

pass view object in applySettings(v);
private int teamOnePoints=0;
private int teamTwoPoints=0;

null pointer exception on radio group

I am trying to make a popup window in an activity. The popup window shows up when we click a button in the activity. The layout for popup window is to show a radio group containing 4 radio buttons, a button and a seek bar and has to return a value to the main activity based on the selected radio button when the button in the pop up window is pressed.
When i run the app and open the pop up window it is giving we this error:
"java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.RadioGroup.setOnCheckedChangeListener(android.widget.RadioGroup$OnCheckedChangeListener)' on a null object reference "
The code for my main activity is:

I tried looking for answer online but didn't really find solution specific to my problem. Please suggest any solutions.
Thanks in advance.

You seem to be inflating the wrong layout. Change the correct layout.xml in
setContentView(R.layout.activity_custom_menu);

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."
