Try something like this in your button listener:

openButton.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
      Intent intent = new Intent();
      intent.setAction(Intent.ACTION_GET_CONTENT);
      intent.setType("file/*");
      startActivity(intent);
   }
}
