Call generic string resource programmatically

Question

in strings.xml I have one resource.

<string name="generic_price_with_rupee_symbol">\u20B9 %s</string>

This is what I do in Android data binding that works perfectly

<TextView
      ...
      android:text="@{@string/generic_price_with_rupee_symbol(item.price)}"
      />

Question:

How to use this resource in java code? As I don't want to make new resource.

I tried

textView.setText(getString(R.string.generic_price_with_rupee_symbol) + "100");

That gives wrong result and prints %s also.

The formatted values should be passed as parameter as second values to getString(int, Object..) method

where Object... is

The format arguments that will be used for substitution

so use

textView.setText(getString(R.string.generic_price_with_rupee_symbol, "100"));
//                                                                  ^^^

It should be written like this -

textView.setText(getString(R.string.generic_price_with_rupee_symbol, "100"));

Use the following:-

textView.setText(getResources().getString(R.string.generic_price_with_rupee_symbol, "100"));
