本文介绍了EditText requestFocus()动态无法正常工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
接下来我要在操作中使用多个Edittexts，我已经在xml中添加了nextFocus值.
I have multiple Edittexts on action next I have added nextFocus values in the xml.
但是，根据未成年人复选框值的状态，一个编辑文本是可见的还是不可见的.因此，我需要在YYYY editext动态之后将重点放在它上. 但动态地，requestFocus()无法正常工作.
But one edit text is either visible or invisible based on the state of under age checkbox value. So I need to set focus on it afterr YYYY editext dynammically. But dynamically the requestFocus() is not working.
单击下一步"后需要做什么
仅当未选中18岁以下复选框时，此电子邮件视图才可见.
在YYYY edittext之后单击下一步时会发生什么:控制权 用户名Edittext.应用崩溃时，我无法在xml中使用FocusNext 每当电子邮件textview消失了
What happends on next button click after YYYY edittext : control goes to username Edittext. I cant use FocusNext in xml as the app crashes whenever the email textview is GONE
dobYearEt.setOnEditorActionListener(new EditText.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
Log.i("focus","on yyyy");
if (actionId == EditorInfo.IME_ACTION_DONE ||
actionId == EditorInfo.IME_ACTION_NEXT) {
Log.i("focus",isUnderAge+"");
if(isUnderAge){
username_reg_ev_dob_row.setFocusableInTouchMode(true);
username_reg_ev_dob_row.requestFocus();
}else{
// NOTHING HAPPENS
// email_ev.setFocusableInTouchMode(true);
// dobYearEt.clearFocus();
email_ev.requestFocus();
// InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
// mgr.showSoftInput(email_ev, InputMethodManager.SHOW_IMPLICIT);
}
return false;
}

我已经提到过各种解决方案，但是没有任何作用
I have referred to various solutions but nothing is working
推荐答案
发生了什么事，我是从onEditorAction返回false的，因此默认编辑器操作也被前后执行，并且焦点立即从电子邮件editText移开了. .现在我返回true并且没有执行默认操作.现在它可以正常工作.
What was happening is the I was returning false from onEditorAction- Hence the default editor action was also performed back to back and the focus instantly moved away from the email editText. Now I return true and the deafult action is not performed.Its working correctly now.
dobYearEt.setOnEditorActionListener(new EditText.OnEditor ActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
Log.i("focus","on yyyy");
if (actionId == EditorInfo.IME_ACTION_DONE ||
actionId == EditorInfo.IME_ACTION_NEXT) {
Log.i("focus",isUnderAge+"");
if(isUnderAge){
username_reg_ev_dob_row.setFocusableInTouchMode(true);
username_reg_ev_dob_row.requestFocus();
}else{
email_ev.requestFocus();
}
return true ; // NOW WORKS
// return false;
}
