问题
I am using a ListView in which only one item can be checked at a time. This is my custom list_row.xml:
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dip"
android:textColor="#FFFFFF"
android:textStyle="bold"
android:textSize="20sp"
android:checkMark="?android:attr/listChoiceIndicatorSingle"
/>
I populate the list in onCreate() using a normal array adapter:
ArrayAdapter<String> myAdapter = new ArrayAdapter<String>(this, R.layout.list_row, strings);
myList.setAdapter(myAdapter);
When the list is displayed, I want to have, say, the 5th item in the list appear as Checked. How can I go about doing this? I know CheckedTextView has a function called setChecked(), but how can I get my 5th item from the list to apply this function on it?
回答1:
Referring another answer in StackOverflow, I have found that the simplest way to achieve this is using
myList.setItemChecked(pos, true);
