You can achieve this by using the <code>Text Watcher</code> class and then set the focus on the next <code>EditText</code> in the <code>OnTextChanged()</code> method of the TextWatcher.

In your case, since you have two Edit Texts, say <code>et1</code> and <code>et2</code>. You can try out the following code:-

<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>

I have not checked out the code myself, but I hope this will help you solve your problem.

There is a simpler way to do this which doesn't involve knowledge of the ids of the EditText views. For use with android:maxLength="1".

<pre><code>// onTextChanged
@Override
public void onTextChanged(CharSequence s, int start, int before, int count)
{
 TextView text = (TextView)getCurrentFocus();

 if (text != null &amp;&amp; text.length() &gt; 0)
 {
 View next = text.focusSearch(View.FOCUS_RIGHT); // or FOCUS_FORWARD
 if (next != null)
 next.requestFocus();

 doSearch(); // Or whatever
 }
}

// afterTextChanged
@Override
public void afterTextChanged(Editable s) {}

// beforeTextChanged
@Override
public void beforeTextChanged(CharSequence s, int start,
 int count, int after) {}

The accepted answer is good.

I provide new way if you are using RxJava + RxBinding library.

The coding indicate 4 input Edit Text need verify (My case is Active code SMS via Phone - Phone Verify)

<pre><code>// Show button Active code when enough fields active code
 Observable&lt;Boolean&gt; mObsPhoneVerify1 = RxTextView.textChanges(db.etPhoneVerify1)
 .observeOn(AndroidSchedulers.mainThread())
 .map(charSequence -&gt; {
 db.etPhoneVerify2.requestFocus();
 return charSequence != null &amp;&amp; !charSequence.toString().equals("");
 }
 );
 Observable&lt;Boolean&gt; mObsPhoneVerify2 = RxTextView.textChanges(db.etPhoneVerify2)
 .observeOn(AndroidSchedulers.mainThread())
 .map(charSequence -&gt; {
 db.etPhoneVerify3.requestFocus();
 return charSequence != null &amp;&amp; !charSequence.toString().equals("");
 });
 Observable&lt;Boolean&gt; mObsPhoneVerify3 = RxTextView.textChanges(db.etPhoneVerify3)
 .observeOn(AndroidSchedulers.mainThread())
 .map(charSequence -&gt; {
 db.etPhoneVerify4.requestFocus();
 return charSequence != null &amp;&amp; !charSequence.toString().equals("");
 });
 Observable&lt;Boolean&gt; mObsPhoneVerify4 = RxTextView.textChanges(db.etPhoneVerify4)
 .observeOn(AndroidSchedulers.mainThread())
 .map(charSequence -&gt; {
 db.etPhoneVerify1.requestFocus();

 hideKeyboard();
 return charSequence != null &amp;&amp; !charSequence.toString().equals("");
 });

 disposable = Observable
 .combineLatest(mObsPhoneVerify1, mObsPhoneVerify2, mObsPhoneVerify3, mObsPhoneVerify4,
 (PhoneVerify1, PhoneVerify2, PhoneVerify3, PhoneVerify4)
 -&gt; PhoneVerify1 &amp;&amp; PhoneVerify2 &amp;&amp; PhoneVerify3 &amp;&amp; PhoneVerify4)
 .compose(regisObserver(false))
 .subscribe(aBoolean -&gt; {
 db.btnActiveCode.setEnabled(aBoolean);

 busDisposables.add(disposable);

If you have a list of TextViews for which you want to shift focus (like getting OTP input) then the following code will help achieve it in less number of lines
<pre><code>TextView otp1 = (TextView) root.findViewById(R.id.edit_verify_otp1);
TextView otp2 = (TextView) root.findViewById(R.id.edit_verify_otp2);
TextView otp3 = (TextView) root.findViewById(R.id.edit_verify_otp3);
TextView otp4 = (TextView) root.findViewById(R.id.edit_verify_otp4);

/* Assign the TextViews in the array in the order in which you want to shift focus */
TextView[] otpTextViews = {otp1, otp2, otp3, otp4}; 

 for (TextView currTextView : otpTextViews) {
 currTextView.addTextChangedListener(new TextWatcher() {
 @Override
 public void beforeTextChanged(CharSequence s, int start, int count, int after) {
 }

 @Override
 public void onTextChanged(CharSequence s, int start, int before, int count) {
 nextTextView().requestFocus();
 }

 @Override
 public void afterTextChanged(Editable s) {
 }

 public TextView nextTextView() {
 int i;
 for (i = 0; i &lt; otpTextViews.length - 1; i++) {
 if (otpTextViews[i] == currTextView)
 return otpTextViews[i + 1];
 }
 return otpTextViews[i];
 }
 });
 }

I have a couple of edit text boxes on a single line. After the user types in a specific number of characters in the first I want to automatically move to the next edit text. How do I achieve this?

How to automatically move to the next edit text in android

我在一行上有几个编辑文本框。当用户在第一个文本中键入特定数量的字符后，我希望自动移动到下一个编辑文本。我该如何实现这一点？
