问题描述
我试图做一个shoppinglist,其中CheckedTextView进行检查,如果你已经选定了项目previously即项目都有一个布尔值设置为true,如果采摘。
我已经重写了getview方法用的setText()和工程变更CheckedTextView文本,但设置在CheckedTextView的setChecked(true)方法犯规不让它检查。
我知道,我不是回收getview(任何意见),这将是该项目以后的项目中,右键知道我需要看到一个绿色的对勾=)
有什么想法?请大家帮忙。

如果您要使用 setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
,则需要使用 setSelection()
在的ListView方法
来表示其接受检查,不能处理自己在行结合。
I am trying to make a shoppinglist, where the CheckedTextView is checked if you have already picked your item previously ie the item has a boolean set to true if picked.
I have overriden the getview method to change the CheckedTextView text with setText() and that works but setting the setChecked(true) method in CheckedTextView doesnt not make it checked.
I know that I am not recycling any views in getview(), that will be a later project in the project, right know I need to see a green checkmark =)
Any thoughts? please help.

test.xml

android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"

android:paddingRight="50dip"
android:textColor="#000000"

If you are going to use setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
, you need to use the setSelection()
method on ListView
to indicate which get checked, not handle that yourself during row binding.
