#### **这是一个SwipeBackLayout(Activity滑动返回)使用Kotlin在项目中自己封装使用教程。** ####

1.这个作为Activity的基类。

2.重写setSwipeBackEnable()的方法可以在某个页面设置当前页面禁止滑动返回(当前Activity关闭滑动功能).

3.官方Demo链接:**[https://github.com/ikew0ng/SwipeBackLayout][https_github.com_ikew0ng_SwipeBackLayout]**

**以下是封装的代码：**

package com.hzq.xiaoqiang.base
    
    import android.os.Bundle
    import android.view.View
    import android.support.v7.app.AppCompatActivity
    import me.imid.swipebacklayout.lib.SwipeBackLayout
    import me.imid.swipebacklayout.lib.Utils
    import me.imid.swipebacklayout.lib.app.SwipeBackActivityBase
    import me.imid.swipebacklayout.lib.app.SwipeBackActivityHelper
    
    
    /**

    @Suppress("UNCHECKED_CAST")
     abstract class BaseSwipeBackActivity : AppCompatActivity() , SwipeBackActivityBase {
    
    
        private var mHelper : SwipeBackActivityHelper? = null
    
    
        override fun onCreate(savedInstanceState : Bundle?) {
            super.onCreate(savedInstanceState)
            mHelper = SwipeBackActivityHelper(this)
            mHelper?.onActivityCreate()
        }
    
        override fun onPostCreate(savedInstanceState : Bundle?) {
            super.onPostCreate(savedInstanceState)
            mHelper?.onPostCreate()
        }
    
    
    
        override fun <T : View?> findViewById(id : Int) : T {
            val v = super.findViewById<T>(id)
            return if (v == null && mHelper != null) mHelper?.findViewById(id) as T else v
        }
    
        override fun getSwipeBackLayout() : SwipeBackLayout {
            return mHelper!!.swipeBackLayout
        }
    
        /**
         * 禁止滑动退出
         * @param enable false 禁止滑动退出
         */
        override fun setSwipeBackEnable(enable : Boolean) {
            swipeBackLayout.setEnableGesture(enable)
        }
    
        override fun scrollToFinishActivity() {
            Utils.convertActivityToTranslucent(this)
            swipeBackLayout.scrollToFinishActivity()
        }
    
    }
