augmify / slideback

A library to close an activity with swipe gestures.

高仿微信视差手势滑动返回库

实现思路参考自「Slidr」和「and_swipeback」

功能

• 无需设置Activity主题透明
• 支持动态切换全局或边缘滑动，亦可动态禁止或恢复滑动
• 支持动态设置边缘响应和滑动关闭距离的阈值
• 页面边缘附有阴影并随滑动距离而渐变
• 优化了与RecyclerView、ViewPager等滑动控件手势冲突
• 支持屏幕旋转

效果图

使用方法

1. 继承Application实现Activity生命周期的监听，ActivityHelper用于保存Activity栈供侧滑库使用

public class MyApplication extends Application {

    private ActivityHelper mActivityHelper;

    private static MyApplication sMyApplication;

    @Override
    public void onCreate() {
        super.onCreate();

        mActivityHelper = new ActivityHelper();
        registerActivityLifecycleCallbacks(mActivityHelper);

        sMyApplication = this;

    }

    public static ActivityHelper getActivityHelper(){
        return sMyApplication.mActivityHelper;
    }
    
}

2.在需要滑动的Activity使用SlideBackHelper去attach当前Activity

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);

    mSlideBackLayout = SlideBackHelper.attach(
            // 当前Activity
            this,
            // Activity栈管理工具
            MyApplication.getActivityHelper(),
            // 参数的配置
            new SlideConfig.Builder()
                    // 屏幕是否旋转
                    .rotateScreen(true)
                    // 是否侧滑
                    .edgeOnly(false)
                    // 是否禁止侧滑
                    .lock(false)
                    // 边缘滑动的响应阈值，0~1，对应屏幕宽度*percent
                    .edgePercent(0.1f)
                    // 关闭页面的阈值，0~1，对应屏幕宽度*percent
                    .slideOutPercent(0.5f).create(),
            // 滑动的监听
            null);
           
    // 其它初始化
}

3.如果开启了屏幕旋转，SlideBackLayout需要监听Activity的结束事件，例如这里的onBackPressed，所以你需要在调用结束事件的地方加上SlideBackLayout.isComingToFinish()

@Override
public void onBackPressed() {
    super.onBackPressed();
    mSlideBackLayout.isCommingToFinish();
    overridePendingTransition(R.anim.anim_none, R.anim.anim_slide_out);
}

4.SlideBackHelper.attach会返回处理侧滑的SlideBackLayout，可在适当时候动态控制侧滑几个参数

  // 是否启用边缘滑动
  mSlideBackLayout.edgeOnly(boolean);
  // 是否禁止滑动
  mSlideBackLayout.lock(boolean);
  // 设置边缘滑动的响应阈值
  mSlideBackLayout.setEdgeRangePercent(float);
  // 设置关闭页面的阈值
  mSlideBackLayout.setSlideOutRangePercent(float);

存在问题

旋转屏幕后上一个Activity的布局也会随之旋转，但是ToolBar比例还是维持旋转之前的比例，无从下手，希望有大神告知>_<
