使用SlidingPaneLayout实现左滑菜单

本文主要是介绍使用SlidingPaneLayout实现左滑菜单，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

众所周知，在Google的Support包中发布了众多令人激动的控件，大大方便了我们实现界面效果，提高开发效率，今天我们来学习一下SlidingPaneLayout：
SlidingPaneLayout位于SupportV4包中，要使用它，我们首先要在build.gradle文件中添加项目依赖，如下所示：

compile 'com.android.support:support-v4:25.1.0'

等待项目重新构建完成后，我们就可以在XML布局文件中使用它了，具体书写方法如下：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout
    xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/spl_root"android:layout_width="match_parent"android:layout_height="match_parent"> 
</android.support.v4.widget.SlidingPaneLayout>

在这里，我们需要注意一点，SlidingPaneLayout需要一个指定的宽度去适配布局，一般使用match_parent。

接下来我们为SlidingPaneLayout添加两个pane，看看大概的效果：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout
    xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/spl_root"android:layout_width="match_parent"android:layout_height="match_parent"><TextView
        android:id="@+id/tv_left"android:layout_width="120dp"android:layout_height="match_parent"android:text="左侧菜单"android:textSize="22sp"android:background="#ff0000"/><TextView
        android:id="@+id/tv_right"android:layout_width="match_parent"android:layout_height="match_parent"android:text="这是内容"android:textSize="24sp"android:background="@color/colorPrimaryDark"/>
</android.support.v4.widget.SlidingPaneLayout>

随后运行项目，效果如下图：
这里写图片描述
随后我们使用ListView搭配ScrollView来实现一种常见的左列表，右侧详情页的效果：
修改布局文件如下：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout
    xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/sliding_pane_layout"android:layout_width="match_parent"android:layout_height="match_parent"tools:context="com.example.tuozhaobing.slidingpanedemo.MainActivity"><ListView
        android:id="@+id/left_pane"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_marginRight="0dp"android:paddingRight="0dp"android:layout_gravity="left"></ListView><ScrollView
        android:layout_width="match_parent"android:layout_height="match_parent"android:scrollbarStyle="outsideOverlay"android:background="#ff333333"><TextView
            android:id="@+id/content_text"android:layout_width="match_parent"android:layout_height="wrap_content"android:text="@string/sliding_pane_layout_summary"android:textAppearance="?android:attr/textAppearanceMedium"/></ScrollView></android.support.v4.widget.SlidingPaneLayout>

随后修改MainActivity.java代码如下：

package com.example.tuozhaobing.slidingpanedemo;import android.support.v4.widget.SlidingPaneLayout;
