android自定义控件（邮箱边写边出格式邮箱）

android可以自定义控件，最近接触到两种自定义控件，记下，为以后遇到时可以复用

public class AutoCompleteEmailEdit extends AutoCompleteTextView {
    private ArrayList<String> candidateString = null;
    private ArrayAdapter<String> adapter = null;
    private Context mContext = null;
    private String previousUserName = null;


public AutoCompleteEmailEdit(Context context) {
super(context);
// TODO Auto-generated constructor stub
}

public AutoCompleteEmailEdit(Context context, AttributeSet attrs) {
         super(context, attrs);
         mContext = context;
     }
   public void init() {
         setInputType(InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);
         candidateString = new ArrayList<String>();
         adapter = new ArrayAdapter<String>(mContext, R.layout.list_candidate, candidateString);
         setAdapter(adapter);
         setThreshold(1);
     }

   public void createCandidateEmail(String name) {
         CharSequence[] mEmailSuffix = null;
         mEmailSuffix = getResources().getTextArray(R.array.EmailSuffix);

         if (name == null || name.indexOf('@') != -1) {
             return;
         }

         for (int i = 0; i < mEmailSuffix.length; i++) {
             String tempStr = name.concat(mEmailSuffix[i].toString());
             adapter.add(tempStr);

if (previousUserName != null) {
String tempPrevStr = previousUserName.concat(mEmailSuffix[i].toString());

                 adapter.remove(tempPrevStr);
             }
         }

         previousUserName = name;
     }

}
