Option 1:

<pre><code>&lt;EditText
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:imeOptions="actionNext"
 android:singleLine="true"/&gt;
</code></pre>

Option 2:

<pre><code>&lt;EditText
 android:id="@+id/et1"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:singleLine="true"
 android:nextFocusForward="@+id/et2"/&gt;

&lt;EditText

This is my approach for editext in recyclerview or listview or whatever.

<pre><code>edittext.setOnEditorActionListener { textView, actionId, _ -&gt;
 if (actionId == EditorInfo.IME_ACTION_NEXT) {
 var view = textView.focusSearch(View.FOCUS_DOWN)
 while (view != null) {
 if (view is EditText) {
 view.isCursorVisible = true
 return@setOnEditorActionListener view.requestFocus()

 view = view.focusSearch(View.FOCUS_DOWN)
 }
 }
 false

According to the question and answer posted <a href="https://stackoverflow.com/questions/12470067/how-to-automatically-move-to-the-next-edit-text-in-android">How to automatically move to the next edit text in android</a> , I used the code to move to the next edit box.

<pre><code>et1.addTextChangedListener(new TextWatcher() {

 public void onTextChanged(CharSequence s, int start,int before, int count) 
 {
 // TODO Auto-generated method stub
 if(et1.getText().toString().length()==size) //size as per your requirement
 {
 et2.requestFocus();
 }
 }
 public void beforeTextChanged(CharSequence s, int start,
 int count, int after) {
 // TODO Auto-generated method stub

 }

 public void afterTextChanged(Editable s) {
 // TODO Auto-generated method stub
 }

});
</code></pre>

The issue I am facing is in case I enter something wrong, then even if the user explicitly request focus , the text box moves to the next one due to the code in the text watcher. Is there anything I can do to prevent this from happening ?

Moving to the next EditText in android

根据发布的问答，我使用代码移动到下一个编辑框。et1.addTextChangedListener(new TextWatcher() {    public void onTextChanged(CharSequence s, int start,int before, int count)     {       ...
