您可以简单地进行数据库查询来这样做。
看看这个method
:
private Boolean createGrp(String GroupName) {
// TODO Auto-generated method stub

for (int i = 0; i < InteractiveArrayAdapter.list.size(); i++) {

}
}

s1 = editText.getText().toString();
// Check the edittext is empty or not
if (s1.equals("")) {
Toast.makeText(getActivity(), "Please Enter Any Text", Toast.LENGTH_SHORT).show();
return false;
}
// Check the Group is available or not
