String data="tv";

Также в моем XML-файле у меня есть TextView с именем tv1. Я бросил textView в деятельности.

TextView tv1 = (TextView) findViewById(R.id.tv1);

I want to cast the string into TextView...

так что я могу выполнить эту операцию над строкой вместо tv1.

data.setText("abc"); // on the string..

Могу ли я достичь этого или нет .. Также, как динамически назначить идентификатор для textView. Thanx ...

Это мой код активности:

public class Winnings extends Activity {

TextView tv1, tv2, tv3, tv4, tv5, tv6, tv7, tv8, tv9, tv10, tv11, tv12,
        tv13, tv14, tv15;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.winnings);
    setupVariables();

    // TODO Auto-generated method stub
    backGroundToChange(7);
}

private void setupVariables() {
    // TODO Auto-generated method stub
    tv1 = (TextView) findViewById(R.id.TextView01);
    tv2 = (TextView) findViewById(R.id.TextView02);
    tv3 = (TextView) findViewById(R.id.TextView03);
    tv4 = (TextView) findViewById(R.id.TextView04);
    tv5 = (TextView) findViewById(R.id.TextView05);

    tv6 = (TextView) findViewById(R.id.TextView06);
    tv7 = (TextView) findViewById(R.id.TextView07);
    tv8 = (TextView) findViewById(R.id.TextView08);
    tv9 = (TextView) findViewById(R.id.TextView09);
    tv10 = (TextView) findViewById(R.id.TextView10);

    tv11 = (TextView) findViewById(R.id.TextView11);
    tv12 = (TextView) findViewById(R.id.TextView12);
    tv13 = (TextView) findViewById(R.id.TextView13);
    tv14 = (TextView) findViewById(R.id.TextView14);
    tv15 = (TextView) findViewById(R.id.TextView15);
}

void backGroundToChange(int position) {

//What i want to do is this..


String data = "tv" + position;

//The casting of string into a TextView and so that I can perform this...

data.setBackgroundResource(R.drawable.option_correct);

// so by this way i don't need the switch and case that was actually used, shown below.....

//We normally implement it this way

    /*
        switch (position) {
    case 1:
        tv1.setBackgroundResource(R.drawable.option_correct);
        break;
    case 2:
        tv2.setBackgroundResource(R.drawable.option_correct);
        break;
    case 3:
        tv3.setBackgroundResource(R.drawable.option_correct);
        break;

        break;
    case 5:
        tv5.setBackgroundResource(R.drawable.option_correct);
        break;
    case 6:
        tv6.setBackgroundResource(R.drawable.option_correct);
        break;
    case 7:
        tv7.setBackgroundResource(R.drawable.option_correct);
        break;
    case 8:
        tv8.setBackgroundResource(R.drawable.option_correct);
        break;
    case 9:
        tv9.setBackgroundResource(R.drawable.option_correct);
        break;
    case 10:
        tv10.setBackgroundResource(R.drawable.option_correct);

        break;
    case 14:
        tv14.setBackgroundResource(R.drawable.option_correct);
        break;
    case 15:
        tv15.setBackgroundResource(R.drawable.option_correct);
        break;

    default:
        break;
