Question

我要验证手机号码，我要输入数据库的编辑文本值搜索，我要获取错误已经为验证setError或Toast消息注册了您的号码，请添加Main类，Model类和AppUtil类的帮助我，下面附有代码。请告诉我我设置的验证内容。

public class CreateRyotManagerFragment extends Fragment {
EditText mRyotName, mRyotFatherName, mAddress, mIdNo, mMobile1;
Spinner mDivision;
List<RyotMasterDb> mRyotList;
List<DivitionMasterDb> mDistrickarray;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    view = inflater.inflate(R.layout.layout_new_ryot, container, false);

    mMobile1 = view.findViewById(R.id.mobile);
    mDivision = view.findViewById(R.id.divition);
    mRyotList = AppUtils.getRyotMasterList();
    mDistrickarray = AppUtils.getDistrictMasterLIst();

    SpinnerAfdapterDistric divisionAdapter = new SpinnerAfdapterDistric(getActivity().getApplicationContext(), mDistrickarray);
    mDivision.setAdapter(divisionAdapter);

}

Answer 1

我建议您使用AutoCompleteTextView。一个可编辑的文本视图，在用户键入时自动显示完成建议。建议列表显示在下拉菜单中，用户可以从中选择一个项目来替换编辑框的内容。

可以通过按返回键随时删除该下拉菜单，如果下拉菜单中未选择任何项目，则可以按Enter / dpad中心键。

建议列表是从数据适配器获得的，并且仅在由the threshold定义的给定数目的字符之后出现。

代码示例：

public class CountriesActivity extends Activity {
   protected void onCreate(Bundle icicle) {
       super.onCreate(icicle);
       setContentView(R.layout.countries);

       ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
             android.R.layout.simple_dropdown_item_1line, COUNTRIES);
       AutoCompleteTextView textView = (AutoCompleteTextView)
             findViewById(R.id.countries_list);
       textView.setAdapter(adapter);
   }

   private static final String[] COUNTRIES = new String[] {
       "Belgium", "France", "Italy", "Germany", "Spain"
   };
}

您可以参考this example以获得详细说明。

您可以为EditText设置keyListener

"\"If you like your doctor, you can keep your doctor.\" -  I don't know
if {Michelle } noticed, but I am not White & I am Not Male.  being
honored by for his rap battle win against"

通过这种方法检查在编辑文本中输入的电话是否在数据库中

editText.setOnKeyListener(new View.OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if(event.getAction() == KeyEvent.ACTION_DOWN && keycode == KeyEvent.KEYCODE_ENTER){
                // do your search in here    
                String mobileno=mmobile.getText().toString();
                //search it  
                boolean isInList = checkIsPhoneNumberInList(mRyotList,mobileno);
                Log.i("CheckResult","is my phone number "+mobileno+" in mRyotList: "+isInList);
                if(isInList){
                   Toast.makeText(getActivity(),"your phone number is already registered",Toast.Toast.LENGTH_LONG).show(); 
                }
            }
            return false;
        }
    });
