Android:如何在Checked ListView中检查特定项目? [英] Android: How can I check a particular item in a Checked ListView?

问题描述

我正在使用ListView，一次只能检查一项. 这是我的自定义list_row.xml:

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"
    />

我使用普通的数组适配器填充onCreate()中的列表:

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);

显示列表时，我想让列表中的第5个项目显示为已选中".我该怎么做呢?我知道CheckedTextView有一个名为setChecked()的函数，但是如何从列表中获取我的第5个项目以对该函数应用呢?

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?

推荐答案

在StackOverflow中引用另一个答案，我发现最简单的方法是使用

Referring another answer in StackOverflow, I have found that the simplest way to achieve this is using

myList.setItemChecked(pos, true);
