How to choose data from vaules in android

Issue

Hi i have some data in values that structured in this way every time i generate random number and i want to show values of that number from values what is the solution

  <string name="info47">hello world</string>
    <string name="info48">hello dolly</string>

    int ok=47;
  infotextView.setText(getString(R.string.info{ok}));

Solution

Try this code:

If in activity like MainActivity you can use this.

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    int ok=47;
    String name="info"+ok;
    TextView infotextView= (TextView) findViewById(R.id.textView);
    infotextView.setText(getStringByName(this,name));
}

public static String getStringByName(Context context, String name) {
    Resources res = context.getResources();
    return res.getString(res.getIdentifier(name, "string", context.getPackageName()));
}
