You need to use TextWatcher so you can catch the \n character and modify text so there is no new lines, heres the magic:

mFirstEditText.addTextChangedListener( new TextWatcher() {

    private boolean mEnterOccurred;

    @Override
    public void onTextChanged(CharSequence text, int start, int before, int count) {
        String textStr = text.toString();
        if(textStr.contains("\n")) {
            // Wipe off the \n
            textStr = textStr.replace("\n", "");
            mEnterOccurred = true;
            mFirstEditText.setText(textStr);
        }
    }

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

    @Override
    public void afterTextChanged(Editable s) {
        if(mEnterOccurred) {
            // Change focus to another EditText
            mSecondEditText.requestFocus();
            // Change flag to default
            mEnterOccurred = false;
        }
    }
});

Use following short of code to get event of Return and disappear keyboard.

(EditText) findViewById(R.id.editText1)).setOnKeyListener(new OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == 66) {
            hideKeyboard(v);
            return true; //this is required to stop sending key event to parent
        }
        return false;
    }
});

In above code 66 is code for Return You can also use KeyEvent.KEYCODE_ENTER as preferred by @JJPA.

Following is code to hide keyboard explicitly.

private void hideKeyboard(View view) {
    InputMethodManager manager = (InputMethodManager) view.getContext()
            .getSystemService(INPUT_METHOD_SERVICE);
    if (manager != null)
        manager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Avoid displaying the return key if you don't want user to press it.

What you can do is, make the EditText singleLine and play around a little with android:nextFocus* to implement a more user friendly IME navigation. For your problem, you can simply modify your EditText from xml like

<EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/edit"
        android:singleLine="true"
/>
