Use Strings with placeholder in XML layout android

Question

I have a string with placeholder e.g

<string name="str_1">Hello %s</string>

I want to use this in xml layout as android:text="@string/str_1". Is there any way to use this in xml layout to fill the placeholder? Thanks in advance. I already know String.format(str,str...) in java/kotlin but i want to use this in xml layout without data binding.

You can use something like this. Write your string in your (strings.xml) with declaring a string variable (%1$s) inside it. For decimal, we use (%2$d).

<string name="my_string">My string name is %1$s</string>

And inside the android code (yourFile.java), use this string where you want it.

String.format(getResources().getString(R.string.my_string), stringName);

This is not a good answer but it may help you get some idea to get going.

Thanks.
