I'm doing a crossword and each field is an EditText as in the example below:

// GRIDLAYOUT USADO PARA ORGANIZAR OS EDIT TEXT EM UMA MATRIZ
<GridLayout
    android:layout_width="match_parent"
    android:layout_height="382dp"
    android:layout_weight="0.26">

     <EditText
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:gravity="center"
        android:id="@+id/letra1_1"
        android:inputType="textCapSentences"
        android:maxLength="1"
        android:singleLine="true"
        android:textSize="25dp"
        android:background="@drawable/square_semborda"
        android:layout_row="1"
        android:layout_column="1"
        />

    <EditText
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:gravity="center"
        android:id="@+id/letra1_2"
        android:inputType="textCapSentences"
        android:maxLength="1"
        android:singleLine="true"
        android:textSize="25dp"
        android:background="@drawable/square_semborda"
        android:layout_row="1"
        android:layout_column="2"
        />

I would like to jump to the next field automatically when the user places a character in the field it is in.

I tried to use the android:nextFocus attribute but it asks enter to jump to another field.

The following is the java code as it was ... but the app stops working when I access the screen of this activity

package com.example.android.cruzadinhas_eic;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.widget.EditText;

public class LeptospiroseActivity extends AppCompatActivity {

public EditText letra1_1;
public EditText letra1_2;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_leptospirose);





    letra1_1.addTextChangedListener(new TextWatcher() {

        public void afterTextChanged(Editable s) {
            letra1_2.requestFocus();
        }

        public void beforeTextChanged(CharSequence s, int start, int count, int after) {


        }

        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }
    });

    }
}

Thank you for your help! hugs

Let's say that the user is editing the letter1 field and you want to position the cursor on letter2 after editing, you can do it like this:

letra2.requestFocus();

try:

public class MainActivity extends AppCompatActivity
{
    public EditText edLetterOne,edLetterTwo;

    @Override
    protected void onCreate(Bundle b)
    {
        super.onCreate(b);
        setContentView(R.layout.activity_main);

        edLetterOne = (EditText)findViewById(R.id.editText);
        edLetterTwo = (EditText)findViewById(R.id.editText2);

        edLetterOne.addTextChangedListener(textWatcher);
    }
    /////////////////////////////////////
    //////////// TextWatcher ////////////
    /////////////////////////////////////
    TextWatcher textWatcher = new TextWatcher()
    {
        @Override
        public void beforeTextChanged(CharSequence c, int i, int i1, int i2){}

        @Override
        public void onTextChanged(CharSequence c, int start, int before, int count)
        {
            if(count > 0) edLetterTwo.requestFocus();
        }

        @Override
        public void afterTextChanged(Editable editable){}
    };
}

and in your layout.xml file where you have your EditText use the

 android:maxLength="1"

Try this, I put it in the after because the action fires after releasing the click, but you can do in other methods or put a test for a certain letter.

yourEditText.addTextChangedListener(new TextWatcher() {

    public void afterTextChanged(Editable s) {
           otherEditText.requestFocus();
    }

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

    public void onTextChanged(CharSequence s, int start, int before, int count) {}
});
