# SwipeBackFragment

An Android library that can finish a Fragment&Activity with swipe-back gesture.

滑动Fragment&Activity边缘即可类似IOS一样，拖动返回。

原理分析：[传送门](http://www.jianshu.com/p/626229ca4dc2),  如果你重度使用Fragment，不妨看看这个库[Fragmentation](https://github.com/YoKeyword/Fragmentation)

# 特性

注: 滑动返回仅支持通过add方式加载的Fragment, replace不支持

1、Activity内Fragment数大于1时，滑动返回的是Fragment，否则滑动返回的是Activity

2、支持左、右、左&右滑动（未来可能会增加更多滑动区域）

3、支持Swipe时的滑动监听

4、帮你处理了Fragment重叠的情况

# Demo演示



# 如何使用

1、项目下app的build.gradle中依赖：

````gradle

// appcompat v7包是必须的

compile 'me.yokeyword:swipebackfragment:0.4.0'

````

2、如果Activity也需要支持SwipeBack，则继承SwipeBackActivity:

````java

public class SwipeBackSampleActivity extends SwipeBackActivity {}

````

同时该Activity的theme添加如下属性：

````xml

 true

````

3、如果Fragment需要支持SwipeBack，则继承SwipeBackFragment:

````java

public class SwipeBackSampleFragment extends SwipeBackFragment {

 @Override

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.xxx, container, false);

        // 需要支持SwipeBack则这里必须调用toSwipeBackFragment(view);

        return attachToSwipeBack(view);

    }

}

````

更多方法:

````java

  // 设置滑动方向

  getSwipeBackLayout().setEdgeOrientation(SwipeBackLayout.EDGE_RIGHT); // EDGE_LEFT(默认),EDGE_ALL

  // 设置侧滑触摸生效区域 MAX,MED,MIN,custom

  setEdgeLevel(SwipeBackLayout.EdgeLevel edgeLevel)

  // 滑动过程监听

  getSwipeBackLayout().addSwipeListener(new SwipeBackLayout.OnSwipeListener() {

            @Override

            public void onDragStateChange(int state) {

                // Drag state

            }

            @Override

            public void onEdgeTouch(int edgeFlag) {

                // 触摸的边缘flag

            }

            @Override

            public void onDragScrolled(float scrollPercent) {

                // 滑动百分比

            }

   });

    // 对于SwipeBackActivity有下面控制SwipeBack优先级的方法:

      /**

        * 限制SwipeBack的条件,默认栈内Fragment数 <= 1时 , 优先滑动退出Activity , 而不是Fragment

        *

        * 可以通过复写该方法, 自由控制优先级

        *

        * @return true: Activity可以滑动退出, 并且总是优先;  false: Activity不允许滑动退出

        */

        @Override

        public boolean swipeBackPriority() {

           return super.swipeBackPriority();

           // 下面是默认实现:

           // return getSupportFragmentManager().getBackStackEntryCount() <= 1;

        }
