前言：

用最简单的例子来说明此问题。

1.在Activity中加上默认的布局Layout

2.在自定义的Layout中实现右滑关闭Activity的逻辑

 直接上代码！

自定义的布局HFFinishRelativeLayout！

package com.huofar.widget;

import android.content.Context;
import android.content.res.TypedArray;
import android.support.v4.app.FragmentActivity;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewGroup;
import android.widget.RelativeLayout;

import com.huofar.util.LogUtil;

/**
 * Created by zhangxiwei on 14/11/25.
 */
public class HFFinishRelativeLayout extends RelativeLayout{

    private static final String TAG = LogUtil.makeLogTag(HFFinishRelativeLayout.class);

    public interface ScrollLeftFinishListener{
        public void finishPage();
    }

    FragmentActivity activity;

    private ScrollLeftFinishListener scrollLeftFinishListener;

    public void setScrollLeftFinishListener(ScrollLeftFinishListener scrollLeftFinishListener) {
        this.scrollLeftFinishListener = scrollLeftFinishListener;
    }

    // 滑动距离及坐标
    private float xDistance, yDistance, xLast, yLast;

    public HFFinishRelativeLayout(Context context) {
        super(context);
    }


    public HFFinishRelativeLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public void attachToActivity(FragmentActivity activity) {
        this.activity = activity;
        TypedArray a = activity.getTheme().obtainStyledAttributes(
                new int[] { android.R.attr.windowBackground });
        int background = a.getResourceId(0, 0);
        a.recycle();

        ViewGroup decor = (ViewGroup) activity.getWindow().getDecorView();
        ViewGroup decorChild = (ViewGroup) decor.getChildAt(0);
        decorChild.setBackgroundResource(background);
        decor.removeView(decorChild);
        addView(decorChild);
        decor.addView(this);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                break;
            case MotionEvent.ACTION_MOVE:

        }

        return super.onInterceptTouchEvent(event);
    }

    @Override

    public boolean dispatchTouchEvent(MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                xDistance = yDistance = 0f;
                xLast = event.getX();
                yLast = event.getY();
                break;
            case MotionEvent.ACTION_MOVE:
                final float curX = event.getX();
                final float curY = event.getY();

                xDistance += Math.abs(curX - xLast);
                yDistance += Math.abs(curY - yLast);
                if (curX > xLast && xDistance > yDistance && xDistance > 300) {
                    if(scrollLeftFinishListener != null){
                        xLast = curX;
                        yLast = curY;
                        scrollLeftFinishListener.finishPage();
                        return true;
                    }
                }
                xLast = curX;
                yLast = curY;
        }
        return super.dispatchTouchEvent(event);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                break;
            case MotionEvent.ACTION_MOVE:
                break;
        }
        <strong><span style="color:#ff6666;">return true;</span></strong>
    }
}

我处理的是每次滑动向右滑动300px执行关闭操作，在需要的使用的Activity实现借口直接finish就OK了！

Activity中的调用：

package com.huofar.activity;

import android.os.Bundle;
import android.os.Handler;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;

import com.huofar.R;
import com.huofar.widget.HFFinishRelativeLayout;

/**
 * Created by zhangxiwei on 14/11/25.
 */
public class HFBaseActivity extends FragmentActivity implements HFFinishRelativeLayout.ScrollLeftFinishListener  {

    private boolean isFinishScrollLeft;
    HFFinishRelativeLayout hfFinishRelativeLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        isFinishScrollLeft = true;
        //延后为了等待需要屏蔽返回滑动接受参数
        new Handler().postAtTime(new Runnable() {
            @Override
            public void run() {
                setFinishScrollLeft(isFinishScrollLeft);
            }
        },1000);
    }

    public void setFinishScrollLeft(boolean isFinishScrollLeft) {
        this.isFinishScrollLeft = isFinishScrollLeft;
        if(isFinishScrollLeft){
            if(isFinishScrollLeft) {
                hfFinishRelativeLayout = (HFFinishRelativeLayout) LayoutInflater.from(this).inflate(
                        R.layout.activity_finish_base, null);
                hfFinishRelativeLayout.attachToActivity(this);
                hfFinishRelativeLayout.setScrollLeftFinishListener(this);
            }
        }
    }


    @Override
    public void finishPage() {
        finish();
    }
}

接下来就是头疼的问题，为什么要这么做：

恶补知识：1.dispatchTouchEvent 2.onInterceptTouchEvent 3.onTouchEvent 传递事件  直接给你们来个学习地址

除此之外看的迷迷糊糊的可以自己写一个demo实践一下 或者多google几个介绍看看，就是事件的传递，然后在dispatchTouchEvent接受一下。然后直接关闭就行。

其实也没有什么，帮助想要该功能的童鞋。

有什么问题可以跟帖询问。
