单选按钮检查单击列表视图 onclicklistener答案

【问题标题】：Radiobutton check on click in listview onclicklistener单选按钮检查单击列表视图 onclicklistener
【发布时间】：2017-04-30 04:39:28
【问题描述】：

我正在使用带有 textview 和 Radiobutton 的列表视图。我想在 Listview onItemClickListener 中实现单选按钮获取检查，我该怎么做？这是我的主要活动。我尝试这样做，但是当我单击 listview 复选框时会检查多项选择，并且当我滚动列表单选按钮框时会丢失其状态。

【解决方案1】：

你可以在costcode_lv_model的父视图上设置onclickListner

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">


<RadioButton
    android:id="@+id/costcode_rb"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ........

给这个RelativeLayout id 并应用onClickListner。

在onClick方法中勾选那边的checkBox。

  holder.costcode_relative.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View view) {

            // code here to set the radioButton checked
            }
        });

【解决方案2】：

您的LitModel 需要有一个属性来保存复选框的状态。

如：

public class LitModel{
    private boolean state;

    public boolean isState() {
        return state;
    }

    public void setState(boolean state) {
        this.state = state;
    }
}

用于设置 LitModel 状态的复选框。

holder.costcode_rb.setChecked(litModels.isState());

当你想改变状态时，改变LitModel的状态，然后刷新。

litModels.setState(true);
notifyDataSetChanged();
