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;
???? }
????
}
