java code which i'm using to achieve what i want like whatsapp's editText but its not working quite well

final AppCompatEditText editText = holder.itemEditText;

        editText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {



                // if edittext has 10chars & this is not called yet, add new line
                if(editText.getText().length() == 34 && !isReached) {

                    editText.append("\n");
                    isReached = true;

                }
                // if edittext has less than 10chars & boolean has changed, reset
                if(editText.getText().length() < 34 && isReached) isReached = false;

                Log.d("char", "onTextChanged: "+charSequence);
                Log.d("i", "onTextChanged: "+i);
                Log.d("i1", "onTextChanged: "+i1);
                Log.d("i2", "onTextChanged: "+i2);

            }

            @Override
            public void afterTextChanged(Editable editable) {


            }
        });

    }

this code is not working like i want it to or you can say i'm not being able to code the way i want editText to act.

i want my editText to work like Whatsapp's editText like when i type something and it reaches to the icon inside the editText, cursor goes to a new line with the typing word. In my editText the words are going underneath the ImageButton which im using as a send icon. i dont want the words to go underneath the send icon. Please Help.

            android:src="@drawable/ic_send" />

Answer 1

Use this

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
}

});
