SmartFormatter

It's an Android library to format strings using a tag instead position. It can be used with String.format(...) to be more powerful.

Using SmartFormatter

You can use the formatter when you want:

<resources>
  <string name="text">This is my {hello_world} Sample {my_project}</string>
</resources>

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

String str = SmartFormatter.getFormatter(mContext)
                .from(getString(R.string.text))
                .with("hello_world","Hello world!")
                .with("my_project","Project!")
                .format()

txt.setText(str);

Using SmartTextView

You can just create your words or texts in strings.xml.

<resources>
  <string name="hello_world">Hello world!</string>
  <string name="my_project">Project!</string>
  <string name="text">This is my {hello_world} Sample {my_project}</string>
</resources>

Using a SmartTextView in your layout xml:

<br.com.smart.formatter.SmartTextView
        android:id="@+id/txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/text" />

And the result is:
