Passing Values from one activity to another, using Object and getting a resource not found error.

Question

I have two pages in my application, I am passing one certain value from one page to another:

Class Level Definition: (From the sending class)

 BuyGold50 BG5 = null;

In onCreate() of the same class:

 BG5 = new BuyGold50();

In a certain function of the first activity--Before calling intent to second Activity

 BG5.SetPrice(Gold);

================================================================================

Code of the BuyGold50 class

public class BuyGold50 extends Activity {

    public static String B;
    static int X;

    public void SetPrice(String Price) {
        B = Price;
        X = Integer.parseInt(B);
    }

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.buy_gold50);
        TextView tv = (TextView) findViewById(R.id.textView1);
        tv.setText(X);
    }

}

Answer 1

Change

 tv.setText(X);

with

tv.setText(String.valueOf(X));

if you pass an int as argument to setText, internally, android will look for a String with that id. If it does not exist it will throws Resources$NotFoundException

Answer 2

You are trying to set int value in

tetview.setText() or Toast.makeText(), which it will take as string resource id.

So try to give int value in like this

.setText(""+intvalue) or Toast.makeText(context,""+intvalue,..)

Answer 3

The error has occurred at com.Geet.BuyGold50.onCreate(BuyGold50.java:21), see your logcat for this. This exception occurred due to the fact that a String was not found which you had passed named Gold in first activity.
