Androidz中DragGrid的基础使用（结合Tablyout）

//首先定义布局

<android.support.design.widget.TabLayout    android:id="@+id/mytab"    app:tabMode="scrollable"    android:layout_width="match_parent"    android:layout_height="wrap_content"    /><ImageButton    android:id="@+id/imgBtn"    android:src="@mipmap/add_recipients_normal"    android:layout_alignParentRight="true"    android:layout_alignParentTop="true"    android:layout_width="35dp"    android:layout_height="35dp" />

//如何使用DragGrid的呢？

1：导入依赖到自己工程下的gradle 

 compile 'com.github.andyoom:draggrid:v1.0.1'

2.在项目的build.gradle中添加
allprojects {
     maven {url "https://jitpack.io"}
3.权限

    <!-- 在SDCard中创建与删除文件权限 -->
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
    <!-- 往SDCard写入数据权限 -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <!-- 震动权限 -->

    <uses-permission android:name="android.permission.VIBRATE"/>
