Any one know how to do it.Is I am going wrong anywhere in code.

MainActivity.java

public class MainActivity extends Activity implements OnClickListener {

        EditText emailEdit, passwordEdit;
        Button loginButton;
        String email, password;
        TitleBarLayout titlebarLayout;
        String r;
        String rr;

        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.login_activity);

            emailEdit = (EditText) findViewById(R.id.etEmail);
            passwordEdit = (EditText) findViewById(R.id.etPassword);

            loginButton = (Button) findViewById(R.id.loginButton);
            loginButton.setOnClickListener(this);

            // titlebarLayout=(TitleBarLayout) findViewById(R.id.titlebar);
            titlebarLayout = new TitleBarLayout(MainActivity.this);
            titlebarLayout.setLeftButtonText("");
            titlebarLayout.setRightButtonText("Logout");
            titlebarLayout.setTitle("iProtect");
            //titlebarLayout.setLeftButtonSize(50,50);
            //titlebarLayout.setRightButtonSize(100,50);
            titlebarLayout.setLeftButtonBackgroundColor(Color.rgb(34,49,64));
            titlebarLayout.setRightButtonBackgroundColor(Color.rgb(34,49,64));
            titlebarLayout.setLeftButtonTextColor(Color.rgb(255,255,255));
            titlebarLayout.setRightButtonTextColor(Color.rgb(255,255,255));


            XmlResourceParser parser =getResources().getXml(R.color.colorstatelist);

                ColorStateList colorStateList;
                try {
                    colorStateList = ColorStateList.createFromXml(getResources(), parser);

                    titlebarLayout.setLeftButtonTextColor(colorStateList);
                } catch (XmlPullParserException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (IOException e) {

                    e.printStackTrace();
                }
    //      ColorStateList colorlist=new ColorStateList( new int[][] { new int[] { android.R.attr.state_focused }, new int[0], }, new int[] { Color.rgb(0, 0, 255), Color.BLACK, } );
    //      titlebarLayout.setLeftButtonTextColor(colorlist);

First, get rid of all the XML parsing stuff from your code. All it's adding is some bugs. There are two approaches you could use, and you should use one or the other, not both.

Your layout XML already sets android:textColor to the state list you want. This is all you need to do. The button text will automatically change colour according to its state. Just remove all the calls to setTextColor from your Java code: at present, those calls are replacing the state list with a static colour. I suggest you completely remove the setLeft/RightButtonTextColor methods from your TitleBarLayout.java, and then let your IDE find all the calls to them, and delete those.

Alternatively, if you want to set the colour from Java code instead of from XML, you just need to call it like this:-

button.setTextColor(getResources().getColorStateList(R.color.colorstatelist));

No XML parsing necessary.
