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, 如果你重度使用Fragment,不妨看看这个库Fragmentation

特性

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:

// appcompat v7包是必须的 compile 'me.yokeyword:swipebackfragment:0.2.0'

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

public class SwipeBackSampleActivity extends SwipeBackActivity {}

同时该Activity的theme添加如下属性:

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

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

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:

 // 设置滑动方向 getSwipeBackLayout().setEdgeOrientation(SwipeBackLayout.EDGE_RIGHT); // EDGE_LEFT(默认),EDGE_ALL // 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 } });
