1、SwipeBackLayout

项目地址：https://github.com/ikew0ng/SwipeBackLayout

2、用法

android studio 

compile 'me.imid.swipebacklayout.lib:library:1.0.0'

项目实例

package com.example.yiba8.myapplication;

import android.os.Bundle;

import android.util.DisplayMetrics;

import android.view.View;

import android.widget.TextView;

import me.imid.swipebacklayout.lib.SwipeBackLayout;

import me.imid.swipebacklayout.lib.app.SwipeBackActivity;

public class BackActivity extends SwipeBackActivity {

    private TextView back ;

    private SwipeBackLayout mSwipeBackLayout;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_back);

        mSwipeBackLayout = getSwipeBackLayout();

        int flag1 =   SwipeBackLayout.EDGE_LEFT ;   //左滑

        int flag2 =   SwipeBackLayout.EDGE_RIGHT ;  //右滑

        int flag3 =   SwipeBackLayout.EDGE_BOTTOM ; //下滑

        int flag4 =   SwipeBackLayout.EDGE_ALL ;    //全部

        //设置滑动模式

        mSwipeBackLayout.setEdgeTrackingEnabled(flag4);

        //自动调用滑动模式

        back = (TextView) findViewById( R.id.back );

        back.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                scrollToFinishActivity();

            }

        });

        //设置是否可以滑动

        mSwipeBackLayout.setEnableGesture(true);

        //获取屏幕的宽度

        DisplayMetrics dm = new DisplayMetrics();

        getWindowManager().getDefaultDisplay().getMetrics(dm);

        int  phoneWidth  = dm.widthPixels ;

        //设置侧滑的区域为屏幕宽度的1/3，如果不设置系统默认为50dip

        mSwipeBackLayout.setEdgeSize( phoneWidth / 3  );

    }

}

3、常见的问题

3.1 滑动后背景显示为黑屏

       

解决方法：在需要侧滑的 Activity 添加一个 Theme

    <!-- Base application theme. -->

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

        <!-- Customize your theme here. -->

        <item name="colorPrimary">@color/colorPrimary</item>

        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>

        <item name="colorAccent">@color/colorAccent</item>

    </style>

    <style name="AppBackTheme"  parent="@style/AppTheme">

        <item name="android:windowIsTranslucent">true</item>

    </style>

对activity添加theme

       <!--  侧滑返回  -->

        <activity

            android:theme="@style/AppBackTheme"

            android:name=".BackActivity">

        </activity>
