switchermod怎么用

       一、各自的功能及使用场景

       ImageView：用于展示一张，例如商品展示；

       Switch：开关、微助力投票系统源码控制器，常用于app设置中；

       DatePicker：日期选择器，网页小偷html源码多用于订阅类的开元免费java源码服务和功能

       二、简单使用

       1、布局部分

xml version="1.0" encoding="utf-8"?LinearLayout xmlns:android="/apk/res/android" xmlns:app="/apk/res-auto" xmlns:tools="/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" android:gravity="center" android:orientation="vertical" ImageView android:id="@+id/iv_img" android:layout_width="dp" android:layout_height="dp" / Button android:id="@+id/btn_todo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="CLICK"/ Switch android:id="@+id/s_toggle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:checked="true"/ TextView android:id="@+id/tv_date" android:layout_width="wrap_content" android:layout_height="wrap_content"/ DatePicker android:id="@+id/dp_date" android:layout_width="wrap_content" android:layout_height="wrap_content" //LinearLayout

       code>

       2、代码部分

       private TextView tvDate; private Button btnTodo; private Switch sToggle; private DatePicker dpDate; private ImageView ivImg; @Override protected void onCreate(Bundle savedInstanceState) private void setListener() ); sToggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() }); if (Build.VERSION.SDK_INT = Build.VERSION_CODES.O) }); } } private void initView() }

       code>

       代码中，我通过sToggle来控制btnTodo是否可点击，将dpDate获取到的日期用tvDate展示，之所以会+1是因为月份获取到的数字是从0开始的
