Android. How can I change a ListView text color on click?

I change the color with this code, but the color changes only when i quit from the application and run it again. How can I resolve to change immediately the color?

adapter2 = new ArrayAdapter<String>(getApplicationContext(),
            android.R.layout.simple_list_item_1, list) {
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view = super.getView(position, convertView, parent);
            TextView text = (TextView) view
                    .findViewById(android.R.id.text1);
            text.setTextColor(Color.parseColor(color));
            return view;
        }
    };

Put this file in res/color folder as textselector_list.xml

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


<item android:state_pressed="true" android:color="#FFFFFFFF"/>
<!-- pressed -->
<item android:state_focused="true" android:color="#FFFFFFFF"/>
<!-- focused -->
<item android:state_selected="true" android:color="#FFFFFFFF"/>
<!-- selected -->
<item android:color="#FF888888"/>
<!-- default -->

And set this as android:textColor="@color/textselector_list" to the listView item i.e. your TextView or Button.

Create res/color/button_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
      android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true"
      android:color="#ff0000ff"/> <!-- focused -->
<item android:color="#ff000000"/> <!-- default -->
</selector>

This layout XML will apply the color list to a View:

<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="TextView"
android:textColor="@color/button_text" />

And if you want to apply State Color Dynamically then

ColorStateList myColorStateList = new ColorStateList(
                    new int[][]{
                            new int[]{android.R.attr.state_pressed}, //1
                            new int[]{-android.R.attr.state_focused}, //2
                            new int[]{android.R.attr.state_selected, android.R.attr.state_pressed} //3
                    },
                    new int[] {
                        Color.RED, //1
                        Color.WHITE, //2
                        Color.BLUE //3
                    }
                );
            title_txt.setTextColor(myColorStateList);
