我正在尝试配置一个简单的表单。我有3个editexts，在用户结束输入后，我想显示已检查的图标，如果它有效（并进入下一个字段），如果没有，则显示错误，用户可以更正。
我的主要问题是我只能输入1个字符，然后显示我或错误或选中图标，然后它会转到下一个字段。
我做错了什么？
这是我的代码：
public class ConTct extends Activity implements OnClickListener, OnTouchListener{
Button mButton;
EditText mFullName, mEmail, mDialZone, mPhone;
static WebView mWebView;
static ProgressBar mProgressBar;
EditText mBrokerId, mIP, mAreaPhonePrefix, mLastName, mPassWord, mCampaign, mSubCampaign, mCountryID, mCity, mAdress, mIsDemo;
private String inputText;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.contct);
registerViews();
}//oncreate()
private void registerViews(){
mFullName = (EditText) findViewById(R.id.firstName);
mFullName.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
//do nothing
}else{
if(!Validation.hasText(mFullName)){
mFullName.setError("You have to input at least 3 characters");
mFullName.requestFocus();
}else{
mFullName.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.llgr, 0);
mFullName.clearFocus();
mEmail.requestFocus();
}
}
}
});
mEmail = (EditText) findViewById(R.id.email);
mEmail.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
//do nothing
}else{
if(!Validation.isEmailAddress(mEmail, true)){
mEmail.setError("wrong email");
mEmail.requestFocus();
}else{
mEmail.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.llgr, 0);
mEmail.clearFocus();
mPhone.requestFocus();
}
}
}
});
mPhone = (EditText) findViewById(R.id.phoneNumber);
mPhone.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
// TODO Auto-generated method stub
if(hasFocus){
//do nothing
}else{
if(!Validation.isPhoneNumber(mPhone, true)){
mPhone.setError("wrong email");
mPhone.requestFocus();
}else{
mPhone.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.llgr, 0);
mPhone.clearFocus();
}
}
}
});
mButton = (Button) findViewById(R.id.SubmitRegisterButton);
mButton.setOnClickListener(this);
}
private void submitForm() {
// Submit your form here. your form is valid
Toast.makeText(this, "Submitting form...", Toast.LENGTH_LONG).show();
}
private boolean checkValidation() {
boolean ret = true;
if (!Validation.hasText(mFullName)){
ret = false;
}
if (!Validation.isEmailAddress(mEmail, true)){
ret = false;
}
if (!Validation.isPhoneNumber(mPhone, true)){
ret = false;
}
if (!Validation.hasText(mPhone)){
ret = false;
}
return ret;
}//checkValidation
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if ( checkValidation () ){
submitForm();
Intent i = new Intent(getApplicationContext(), ThanksZuser.class);
startActivity(i);
finish();
//send to our crm
grabURL(myURL);
}else
Toast.makeText(ConTct.this, "Form contains error", Toast.LENGTH_LONG).show();
}
}//ConTct.class

我的主要问题是我只能输入1个字符，然后它会显示我或 错误或选中的图标，它会转到下一个字段。
问题是：
您正在onTextChanged中调用验证方法。所以它进入hasText方法，确定少于3个字符，并显示错误。在您的情况下，最好使用OnFocusChangeListener
示例：
myEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
//do nothing
}else {
// validate here and show error if invalid and set focus to this element again using requestFocus.
}
}
});
希望这有帮助。
