Android how to trim sharedpreferences name

Question

I'm getting all sharedpreferences created by my app and I insert them in a spinner but every sharedpreferences displayed like "example.xml" etc. I want to trim .xml extension let them just names like "example".

File prefsdir = new File(getApplicationInfo().dataDir,"shared_prefs");
   if(prefsdir.exists() && prefsdir.isDirectory()){
        String[] list = prefsdir.list();
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, android.R.id.text1,list);
        Spinner sp = (Spinner) findViewById(R.id.tum_ilaclar);
        sp.setAdapter(adapter);
   }

You can use something like this create a new method:

String[] getList(String[] list){
    String values[] = new String[list.length];
    for(int i=0; i<list.length; i++){
        String value = list[i];
        values[i]=value.contains(".xml")?value.replace(".xml",""):value;
    }
    return values;
}

Then in your code change :

String[] list = prefsdir.list();

to

String[] list = getList(prefsdir.list());

This will remove the .xml part.
