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>
