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);
    }

}

int 値を設定しようとしています

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

したがって、このように int 値を指定してみてください

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

変化する

 tv.setText(X);

と

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

int を引数として setText に渡すと、内部的に、Android はその ID を持つ文字列を探します。存在しない場合はスローしますResources$NotFoundException

でエラーが発生しましcom.Geet.BuyGold50.onCreate(BuyGold50.java:21)た。これについては、logcat を参照してください。この例外は、最初のアクティビティでString名前を指定して渡した が見つからなかったために発生しました。Gold
