How to disable onItemSelectedListener to be invoked when setting selected item by code

由 ≡放荡痞女 提交于 2019-12-02 23:27:47
Just wondering how you handle the following problem: a result is calculated depending on two spinners' selected items. To handle the UI things, i.e. a user picks a new item in one of the spinners, I install a listener using setOnItemSelectedListener for the spinner in my onCreate() method of the activity. Now: that works, of course, fine. The listener's work is to trigger a new calculation of the result. The problem: because I intercept onPause() onResume() to save/restore the last state, I got a method that sets these two spinners' selected item programmatically like in here: startSpinner

Disabling Spinner in android

由 為{幸葍}努か 提交于 2019-12-02 23:15:22
I'm having problems when using android:enabled="false" , it's not disabling the component in the case it's a spinner . Don't know if it's relevant, but it belongs to a layout that's part of a viewflipper . Any hints or workarounds ? Thanks himb2001 Disable or enable it before setting the adapter. yourSpinner.setEnabled(false); yourSpinner.setClickable(false); yourSpinner.setAdapter(typeAdapter); It's not possible to enable/disable a Spinner in XML (yet). To do so you have to do it in code. Here's an example: Spinner spinner = (Spinner) findViewById(R.id.mySpinner); spinner.setEnabled(false);

Fragment loading spinner/dialog in Honeycomb

由 こ雲淡風輕ζ 提交于 2019-12-02 22:52:35
When loading data into my Fragments I would would like to have an indeterminate spinner in the middle of the fragment (example in pic below) to show the user that content is loading within that particular pane. What's the best way to do this in Honeycomb? I don't really want to use a spinner in the action bar, it's not immediately obvious where data is loading. Also, I don't want an indeterminate progress dialog because it appears in the center of the entire app and also stops the user from doing anything else until it is dismissed. N.B. FragmentDialogs seem to do this also. Am I going to have

How do I set the maximum length for a spinner's drop-down list?

由 不羁的心 提交于 2019-12-02 20:40:53
I have a spinner which currently obscures some text below the spinner when opened. I need to limit the maximum drop-down length of the spinner, either through java code or through XML, so that it does not obscure this text. The current design is the left example while the desired design is on the right. How do I go about limiting how far the spinner drops down to when opened? At present, it drops down to fill the entire portion of screen below it. One way to achieve this is to use ActionBarSherlock 's IcsSpinner. I made the needed modifications to limit the size of the spinner and that seems

How to set Spinner Default by its Value instead of Position?

由 ε祈祈猫儿з 提交于 2019-12-02 16:07:36
I have 1-50 records in the database. I am fetching those data using cursor and set those values to Spinner using Simple Cursor Adapter. Now what i need is i want to set one value say 39th value as default. But not by its position i want to set by its value. I know how to set the spinner default by its position spinner.setSelection(39) will set the spinner to that value. But i didn't have any idea about setting the spinner default by its value(text) in the database. I know the values in the database. For eg "books" is one of the value in the spinner. I need to set the spinner default as books.

method “onItemSelected” doesn't work in array adapter and also in fragment
