Answer 1

Here you have stringName as a text in your textView1 . You can fetch String value programatically from resourses by stringName .

Step1 : first fetch this both values, and store it in a variable;

String mTvTextStrName = textView1.getText().toString().trim();
String strValue = getStringResourceByName(mTvTextStrName);

use this method to fetch String value.

private String getStringResourceByName(String aString) {
  String packageName = getPackageName();
  int resId = getResources().getIdentifier(aString, "string", packageName);
  return getString(resId);
}

You can also check this values via Log.e .

Step2 : Now set your strValue in your textView2 .

// Do your code.. Show Apple
   textView2.setText(strValue);

Answer 2

Try using getIdentifier() method of getResources() like below.

    TextView textView1= findViewById(R.id.textView1);
    TextView textView2= findViewById(R.id.textView2);
    String textViewText=getResources().getString(getResources().getIdentifier(textView1.getText().toString(), "string", getPackageName()));
    textView2.setText(textViewText);
