Opening Specific Card item in RecycleAdapter from different Activity

I will make this as specific as possible. I've created a Page Which uses RecyclerAdapter to show card items in grid.And I have set a Default Activity for each card using OnclickListner ,So when you click any card item it will take you to that Default Activity Like this Image.And mine one Look Like this click here.My question is how can I open a perticular card in recyler Adapter from a different activity.In my app I want that when I press Go button on popup It will it toggle lvl2 or the next card to open the game activity.

What I understand is you want to open different activities on each card click.If it's correct then,
use switch inside your onClick and open your activity on a particular item click
#Override
public void onClick(View v) {
final Intent intent;
switch (getAdapterPostion()){
case 0:
intent = new Intent(context, FirstActivity.class);
break;
case 1:
intent = new Intent(context, SecondActivity.class);
break;
...
default:
intent = new Intent(context, DefaultActivity.class);
break;
}
context.startActivity(intent);
}
Or Use:-
#Override
public void onClick(View v) {
final Intent intent;
if (getAdapterPosition() == sth){
intent = new Intent(context, OneActivity.class);
} else if (getPosition() == sth2){
intent = new Intent(context, SecondActivity.class);
} else {
intent = new Intent(context, DifferentActivity.class);
}
context.startActivity(intent);
}

Shared preferences allows you to save and retrieve key, value pair data.
Initialization:
SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0);
// 0 - for private mode
Editor editor = pref.edit();
Storing Data:
editor.putString("key_name", "string value"); // Storing string
editor.commit(); // commit changes
Retrieving Data:
pref.getString("key_name", null); // getting String
To know more about SharedPreferences or to try out a simple example, check this

You can only save key-value pairs for some of the primitives and String (String set also) only. Android views can never be saved anywhere.
SharedPreferences manager =PreferenceManager.getDefaultSharedPreferences(context);
Use it for saving and retrieving data as follows
// for saving data
manager.edit().putString(context.getString(AT), YOUR_TEXT).commit()
// for retrieving data
manager.getString(context.getString(AT), "");

EditText on touch

I have a DateTimePicker with a little "amount" editext that I save the Sharedpref
but for some reason if I "touch" the EditText and enter the amount in manually, the text is black and doesn't transfer to the TextView, if using the imagebuttons increase and decrease the editText will work as intended. If I enter the dates and times in this manner though it does work, what am I missing?
ImageButton increase = (ImageButton)mDateTimeDialogView.findViewById(R.id.increase);
increase.setOnClickListener(new OnClickListener(){
public void onClick(View v){
amountt++;
amountText = Integer.toString(amountt);
amountedit.setHint(amountText);
amnt.setText(amountText);
editor.putString("numbers", amountText);
editor.commit();
}
});
ImageButton decrease = (ImageButton)mDateTimeDialogView.findViewById(R.id.decrease);
decrease.setOnClickListener(new OnClickListener(){
public void onClick(View v){
amountt--;
amountText = Integer.toString(amountt);
amountedit.setHint(amountText);
amnt.setText(amountText);
editor.putString("numbers", amountText);
editor.commit();
}
});
The relevant EditText info
amountedit=(EditText)mDateTimeDialogView.findViewById(R.id.amountedit);
The TextView it displays to
amnt = (TextView)findViewById(R.id.amountText);
The XML of EditText

Your code isn't clear, you should post code about that EditText you're talking about.
BTW, to get what you would like, you can try to do Sharedpref's edit & commit
when your EditText's text changed, although it's a bad design...
You need a Text change listener
EditText.addTextChangedListener(new TextWatcher()
{
#Override
public void onTextChanged(CharSequence s, int start, int before, int count)
{}
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{}
#Override
public void afterTextChanged(Editable s)
{}
});

Eclipse says onClickListener variable in Android cannot be resolved, but has been created?

In my project i several onClick listeners, and all of them are fine, but one, i can not find and error in the code, if i delete the code and retype it and save it, it is fine without errors, if i close and eclipse and comeback later, variable cant be resolved again.
This is where it cant be resolved in the code:
Button webButton = (Button) newStockRow.findViewById(R.id.webButton);
webButton.setOnClickListener(getStockFromWebClickListener);
and this is how i create it:
public OnClickListener getStockFromWebClickListener = new OnClickListener(){
#Override
public void onClick(View arg0) {
TableRow tableR = (TableRow) arg0.getParent();
TextView stock = (TextView) tableR.findViewById(R.id.stockSymbolTextView);
String stockSymbol = stock.getText().toString();
String stockURL = getString(R.string.yahoo_stock_url) + stockSymbol;
Intent getStockWebPage = new Intent(Intent.ACTION_VIEW, Uri.parse(stockURL));
startActivity(getStockWebPage);
}
};

That's indeed an annoying problem with importing an inner class (or interface) on Eclipse.
What you have to do is instead of:
new OnClickListener()
Write:
new View.OnClickListener()
And make sure that android.view.View is imported.

How to use Application class to share variables while extending Activity class

Im having problem sharing a global variable that I need to retain across multiple activities. This variable is created in TextPlay class and copied onto DailyDataEntry class. I have done some research sharing variables between two activities using Intent but Im looking to share that variable to multiple classes. I think I will have to extends Application but all my other classes are extending Activity already. How am I supposed to extend Application while extending Activity? Thanks a million

Create class that will extends to Application and use it in the following manner whenever you need it:
MyApplication myAppHelper = (MyApplication) context.getApplication();
myAppHelper.setWhatever(whatever);
Whatever whatever = myAppHelper.getWhatever();
