Question

I have a small timer app and EditText widgets named etH, etM and etS which allow input and show the time ticking. When the start button is clicked and the timer is started, I forbid the interaction by doing the following:

btnS.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
    if (calculateMS() != 0) {
        OnTimerStartButtonClicked();
        initiateTimer();
        DisableEditTexts();
                    ...

The method:

public void DisableEditTexts() {
    etH.setFocusable(false);
    etM.setFocusable(false);
    etS.setFocusable(false);
}

By pressing the reset button I want to re-enable the interaction by calling the method the does the reverse thing (sets focusable to true):

btnR.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        OnTimerResetButtonClicked();
        clearValues();
        EnableEditTexts();
        ...

The problem: the edittexts do NOT become focusable by clicking the reset button. All I’m doing in last method is

etH.setFocusable(true);
etM.setFocusable(true);
etS.setFocusable(true);

What am I doing wrong?

Answer 1

Try calling EditText#setFocusableInTouchMode() instead:

etH.setFocusableInTouchMode(true);
// etc.

When you call setFocusable(false), behind the scenes, setFocusableInTouchMode(false) is called for you. However when you call setFocusable(true), nothing else happens behind the scenes, leaving setFocusableInTouchMode() as false.

When you call setFocusableInTouchMode(true), a similar thing happens, setFocusable(true) is called for you. And the same as before setFocusableInTouchMode(false), does not call setFocuable(false).

Take a peak at the source code to see this quirk.
