Dynamic String using String.xml in Android

This is a note for me, that I found a way to load string from String.xml in Android development.

Here is the original code that I use before optimize.

         if ("A".equals(SpeakTextString)) {
             textViewTextToSpeak.setText(getString(R.string.A));
         } else if ("B".equals(SpeakTextString)) {
             textViewTextToSpeak.setText(getString(R.string.B));
         } else if ("C".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.C));
         } else if ("D".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.D));        	
         } else if ("E".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.E));
         } else if ("F".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.F));
         } else if ("G".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.G));
         } else if ("H".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.H));
         } else if ("I".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.I));
         } else if ("J".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.J));
         } else if ("K".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.K));
         } else if ("L".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.L));
         } else if ("M".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.M));
         } else if ("N".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.N));
         } else if ("O".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.O));
         } else if ("P".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.P));
         } else if ("Q".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.Q));
         } else if ("R".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.R));
         } else if ("S".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.S));
         } else if ("T".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.T));
         } else if ("U".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.U));
         } else if ("V".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.V));
         } else if ("W".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.W));
         } else if ("X".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.X));
         } else if ("Y".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.Y));
         } else if ("Z".equals(SpeakTextString)) {
        	 textViewTextToSpeak.setText(getString(R.string.Z));
         }

Can be written in few code loading string from String.xml dynamically

String stringName = "" + SpeakTextString.toUpperCase();
textViewTextToSpeak.setText(getString(getStringResource(getApplicationContext(),stringName)));

public int getStringResource(Context context, String name) {
        int resId = context.getResources().getIdentifier(name, "string", "com.juzhax.learnabc");
        return resId;
}   

While my res/values/strings.xml is

< ?xml version="1.0" encoding="utf-8"?>
<resources>

    <string name="LearnABC">Learn ABC</string>
    <string name="app_name">Learn ABC</string>
    <string name="A">Apple</string>
    <string name="B">BlueTooth</string>
	<string name="C">Chat</string>
	<string name="D">Download</string>
	<string name="E">Email</string>
	<string name="F">Facebook</string>
	<string name="G">Google</string>
	<string name="H">Hewlett Packard</string>
	<string name="I">iPhone</string>
	<string name="J">Java</string>
	<string name="K">KingSton</string>
	<string name="L">Lenovo</string>
	<string name="M">Messenger</string>
	<string name="N">Nikon</string>
	<string name="O">Opera</string>
	<string name="P">Photo shop</string>
	<string name="Q">QR Code</string>
	<string name="R">RSS</string>
	<string name="S">Skype</string>
	<string name="T">Twitter</string>	
	<string name="U">USB</string>
	<string name="V">Vista</string>
	<string name="W">Wifi</string>
	<string name="X">X Box</string>
	<string name="Y">YouTube</string>
	<string name="Z">Zip</string>

</resources>
