Multiple choice alert dialog with custom row layout

由 微笑、不失礼 提交于 2019-12-21 20:19:12
问题 I need to create an AlertDialog with multiple choice items but I'm having some trouble trying to set a custom layout file to the internal ListView. For single choice items I use a constructor that takes a ListAdapter as parameter and this way I can set the proper layout resource for each row: builder.setSingleChoiceItems(new ArrayAdapter<String>(getActivity(), R.layout.list_item_single_choice_answer, items), checkedItem, new DialogInterface.OnClickListener() { @Override public void onClick

SectionIndexer with GridView in Android

由 半腔热情 提交于 2019-12-21 19:47:48
问题 Is it possible to use a SectionIndexer with a GridView in Android? Fast scroll is working fine, and I'm using a custom adapter that extends BaseAdapter . The adapter is currently implementing SectionIndexer and seems to be identical to the examples shown online and on Stack Overflow. This made me think if it's even possible to do with a GridView and a custom adapter. 回答1: static class YOUR_ADAPTER extends SimpleCursorAdapter implements SectionIndexer { private AlphabetIndexer mIndexer; YOUR

由 半世苍凉 提交于 2019-12-21 04:21:28

In order to do this, in the method getView of my adapter i set a field isRead when the row for that item is painted. But the problem is the following: since the method

Dynamic data for Adapter attached to EditText

由 社会主义新天地 提交于 2019-12-21 02:55:19
问题 Is there a way to attach dynamic adapter to EditText? What I want is - when a key is pressed on EditText, my code to do a search in (some) custom store and provide suggestions (instead of static Xml-list or array). This store is not a database; I think CursorAdapter is for database results only. Example code snippets are welcomed. 回答1: I found the solution and posted the answer to this question. Write a custom SimpleCursorAdapter . Override runQueryOnBackgroundThread() method and return a new

Android, Custom ListAdapter get TextView-Text

由 只愿长相守 提交于 2019-12-20 23:26:48
问题 I coded an own Adapter and added it to my ListActivity via an ListView. The reason why I wrote an own Adapter is, that i had to make some layout changes to the list-entrys. In every entry of the list i've got 3 TextViews. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <TextView android:id="@+id/myNr" android

What is an adapter class?

由 风格不统一 提交于 2019-12-20 11:36:21
问题 I googled and investigated, but I still need some clarification: Are an adapter class and a controller class similar? If not, in what way they do differ? Kindly explain. 回答1: Adapter is a pattern that provides default (often empty) implementation of interface or abstract class. For example MouseAdapter provides empty implementation of MouseListener interface. It is useful because very often you do not really use all methods declared by interface, so implementing the interface directly is very

What is the difference between listeners and adapters?

由 天涯浪子 提交于 2019-12-20 10:25:10
问题 I'm trying to differentiate between listeners and adapters. Are they pretty much the same but in listeners you have to implement all the methods in the interface, but with adapters you have an option to only implement the methods you need so the code is cleaners and easier to read? I also got told that adapters enable instantiation with only one implementation and you can't instantiate listeners, I don't fully understand this. Can someone please explain which one is better to use and things
