Unable to set RadioGroup programmatically when another radiogroup element is checked

I am trying to programmatically generate two RadioGroups. I have succesfully generated the first one but I need to generate the second one onCheckedChangeListener of the first radio group. Here is my code for the activity.

do you not just need to repeat the same proccess inside the onCheckChangedListener?
rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
//Create another radio group here
//then add it to the view
RadioGroup rg2 = new RadioGroup(this); //create the RadioGroup
rg2.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL
rg2.setPadding(dpAsPixels, dpAsPixels, dpAsPixels, dpAsPixels);
final Drawable drawableTop = getResources().getDrawable(R.drawable.document_icon);
for (int i = 0; i < itemTypeArrayList.size(); i++) {
if (itemTypeArrayList.get(i).getActive() == 1) {
rb = new RadioButton(this);
rg2.addView(rb); //the RadioButtons are added to the radioGroup instead of the layout
rb.setText(itemTypeArrayList.get(i).getCode());
rb.setId(itemTypeArrayList.get(i).getId());
}
}
itemDetailsLinearLayout.addView(rg);
}
});
You may need to declare rg2 public at the top of the class so it can be accessed by the onCheckChangedListener

update your xml file remove onClick from your button
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Add"
android:id="#+id/add"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/sub"
android:id="#+id/sub"
/>
Problem is with your getting value from sharedPreference
String v=sharedPreferences.getInt("value","");
why are you passing string as default value and your
try this String
v = Integer.toString(sharedPreferences.getInt("value",0));

in the layout you´ve got android:onClick="add" there should be a public void add(View v) to handle the event. Do the sum inside that handler.
Please, follow the documentation
http://developer.android.com/reference/android/widget/Button.html and see the :onCLick handling.

Datepicker and TimePicker dialogs take two clickes of button

So for the life of me I can not find the reason behind needing to click twice on the start date and start time for the picker dialog to open. I have searched these forums many times and they have all been mostly related to edit text fields whereas mine is a simple button but the onClickListener takes two hits. Thanks in advance.

Hmm, your code looks ok. Can you try adding android:focusable="false" to your buttons. I'm curious if the problem is that you're just requesting focus the first click and the second actually initiates the click.
Also, if this doesn't help, can you put some logs in your click listener and also in the public void showTimePickerDialog(View v) { method as well ... to see if it's triggered the first click at all.

Try to add delay on button click it will avoid multi click
date.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
date.setEnabled(false);
showDatePickerDialog(main);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
date.setEnabled(true);
}
}, 100);
}
});

how to use shared preference on multi textview,multi checkbox,multi button and multi edit box in android?

sqlite database practice in android

I have made an application simple in android for database practice,as i have no idea about Sqlite database I've gone through so many links for it,But most of them are complex,I have created 4 activities 1st (mainActivity) contains 3 Buttons "add","Edit", and "View" in 2nd activity (AddActivity) I have made 3 EditTexts its entered values should be stored in database.So can you please tell me easy steps for doing same?

Here I make an app in which you can add ,edit and update your database.i use Two main classes First DataBaseSqlLiteHelper.java to create databse and DatabaseConstants.java to create table. To delete item from db click on list and for update first enter value in edit text.comment on this if you need further help.

Ok if you want only a single value to show on database then you can do like this
take a textView
TextView txtName;
initialize it in my above method of initialize();
then make a method to get single value
// Getting single Name to textView
public void getContact(String id) {
SQLiteDatabase db = mBaseSqlLiteHelper.getReadableDatabase();
String select="Select name from NAMES Where _id ="+id;
Cursor mCursor=db.rawQuery(select,null);
if (mCursor!=null) {
mCursor.moveToFirst();
String name=mCursor.getString(0);
txtName.setText(name);
}
db.close();
}
then call this method on the click of some button and pass the id of the row you want to select.
