修改用户头像
加载图片使用Glide框架
添加权限：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.lotus.looppicturesdemo">
//权限:网络请求、外部存储
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
intent-filter>

manifest>在appa的gradle里声明一下
//引进glide图片加载
compile 'com.github.bumptech.glide:glide:3.7.0'对话框使用alertview
在appa的gradle里声明一下
//引进alertview对话框
compile 'com.bigkoo:alertview:1.0.2'实际使用代码为：
Glide.with(HomeActivity.this).load(xxxURLxxx).into(想显示的控件);
如：Glide.with(HomeActivity.this).load(Constant.Server_IP + userInfo.getTouxiang()).into(imgUserIcon);实际实现代码
文件对象使用了一个自定义的名为FileMode的实体类，根据需要可做更改
1.xml相应布局为：
<LinearLayout
android:orientation="horizontal"
android:id="@+id/layout_user_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@color/colorWhite"
android:padding="10dp"
android:gravity="center_vertical">
<ImageView
android:background="@mipmap/ic_launcher_round"
android:id="@+id/img_user_icon"
android:layout_width="70dp"
android:layout_height="70dp" />
<TextView
android:gravity="right"
android:drawablePadding="5dp"
android:layout_marginLeft="20dp"
