Question

I am using a ListView as shown below in filename browse.xml.

<ListView
   android:id="@+id/listView1"
   android:layout_width="250dp"
   android:layout_height="match_parent"
   android:layout_alignParentLeft="true"
   android:layout_below="@+id/relativeLayout1" >

</ListView>

And I am filling this listView inside onCreate() method as:

files1=new ArrayList<String>();
File sdcard=Environment.getExternalStorageDirectory();
files1 =  getListFiles(new File(sdcard.getAbsolutePath()+File.separatorChar)); 
ArrayAdapter<String> fileList =new ArrayAdapter<String>(this, R.layout.row,files1);

setListAdapter(fileList);

row.xml is shown below as:

<?xml version="1.0" encoding="utf-8"?>
<TextView 
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/rowtext"
   android:layout_width="fill_parent"
   android:layout_height="40dp"
   android:textSize="20dp" 
   android:textColor="#000000"   
   android:background="#FFFFFF"/>

This whole program is am showing all the files of sdcard at listView and on click of any listitem, am saving that file name into sharedPrefernce..Now I want to change the text color of file name(List items) in the ListView which are there in SharedPrefernce..

[EDIT]: Here am using ArrayAdapter default constructor to list all the items in a listview

Pls suggest me something..
Thanks..

We can change the textcolor dynamically for list item in the getView() of Adapter.

public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;

    if (row == null) {
        row = LayoutInflater.from(parent.getContext()).inflate(R.layout.row, null);
    }

    TextView listTitle = (TextView) row.findViewById(R.id.rowtext);
    listTitle.setTextColor(Color.parseColor("#405478"));

    return listTitle;
}
