How to get Spinner inside ListView work in Android?

由 妖精的绣舞 提交于 2020-01-25 09:12:04
问题 I am developing an app in which I need a ListView whose rows have a TextView, 2 CheckBox and a Spinner. However, I am experiencing issues with onItemSelected() of the Spinner, as it gets called each time it is displayed for each row. In this method I am updating database records with the selected option, but as Android calls it automatically, every time the items get reset because Android calls it with position 0 and this is the value updated in the database. I have read a lot of links about

Android spinner position and if statements

由 China☆狼群 提交于 2020-01-24 23:54:27
问题 Having an odd issue here and don't know why it doesn't work, I'm not that used to java yet. to determine the selected item what needs to be done? the spinner has 8 items and 'position' never = 1, or any other number. onItemSelected() is definitely getting fired so is the if statement wrong? public void onItemSelected(AdapterView parent, View v,int position, long id) { if (position == 1) //do something } EDIT: thanks Lion it turns out position doesnt seem to do anything. however, this works.

由 十年热恋 提交于 2020-01-24 12:38:28
问题 I'm using a Spinner with the new style Base.Widget.AppCompat.Spinner.Underlined I can see the underline and the line is shown with the accent color while I'm selecting the option. The problem is that I could not find a way to show the error with the red underline like Google does for all its app for the date of birth for example. To see the error try to add a new account in any of the Google apps. It will ask you for the date of birth. Enter an invalid date and then press next. Is there a way
