android – Spinner does not get focus-ThrowExceptions

Exception or error:

I’m using 4 EditText fields and 2 spinners in an activity. The order of these components are 2 EditText, then 2 spinners and then 2 EditText fields.

The problem occurs when I transfer focus (with the help of soft keyboard next button) from EditText to spinner, spinner does not get the focus and the focus is transferred to the next EditText field that was placed after the spinners.

I have used requestfocus() on spinner, but it did not work.

How do I make sure the spinner gets focus?

How to solve:

I managed to find a solution other then repositioning my Spinner. In the EditText before the spinner, add this listener:

editTextBefore.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView textView, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_NEXT) {
            hideKeyboard();
            textView.clearFocus();
            spinner.requestFocus();
            spinner.performClick();
        }
        return true;
    }
});

You also need to add these line to able spinner to get focus:

spinner.setFocusable(true); // can be done in XML preferrable

My hideKeyboard function was just a visual detail that I wanted to add so the keyboard get hidden:

private void hideKeyboard() {
    InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    inputManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(),
            InputMethodManager.HIDE_NOT_ALWAYS);
}

Hope I have helped in this tricky question.
The flag InputMethodManager.HIDE_NOT_ALWAYS can be found in the documentation.

Thanks, I have solved by doing the following:

  1. I set the Spinner object on top (within the onCreate method) just to make sure that my code gets executed first
  2. I used the following:

    Spinner s1 = (Spinner) findViewById(R.id.spinner1); 
    s1.setFocusable(true); 
    s1.setFocusableInTouchMode(true);
    s1.requestFocus();

This is a shot in the dark, but try setting the focusable property (in XML or in code; whatever way you are doing it) to true on the spinner.

EDIT: Also, see this question: Can't manage to requestFocus a Spinner

I just had the same problem. I solved it using the nextFocusDown/Up/Left/Right properties.

<EditText
    android:id="@+id/tPhone"
    ...
    android:focusableInTouchMode="true"
    android:focusable="true"
    android:nextFocusDown="@+id/sCountry"/>

<Spinner
    android:id="@+id/sCountry"
    ....
    android:focusableInTouchMode="true"
    android:focusable="true"
    android:nextFocusUp = "@+id/tPhone"
    android:nextFocusDown="@+id/tStreet"/>

 <EditText
    android:id="@+id/tStreet"
    ...
    android:visibility="gone"
    android:focusableInTouchMode="true"
    android:focusable="true" 
    android:nextFocusUp = "@+id/sCountry"/>

But why this is even neccessary… beats me.
