SwipeBackLayout(Activity滑动返回)使用Kotlin封装使用

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

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()
    }

}
