让布局支持上下滑动消失

使用

  1. 配置

    项目build.gradle中添加:

    allprojects {
    		repositories {
    			...
    			maven { url 'https://jitpack.io' }
    		}
    	}

    module的build.gradle中添加:

    dependencies {
    	        implementation 'com.github.chrissen0814:ElasticDragDismissLayout:0.0.1'
    	}
  2. 布局中添加View

    <com.chrissen.core.ElasticDragDismissFrameLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/elastic_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".DetailActivity"
        app:dragDismissDistance="112dp"
        app:dragDismissScale="0.95">
    
       ......
    
    </com.chrissen.core.ElasticDragDismissFrameLayout>

    注意:子布局需要实现NestedScrollingChild2接口,官方组件中已经实现了该接口的组件有:RecyclerView、NestedScrollView等,否则没有效果。

  3. 在代码中设置监听回调

    mLayout.addListener(new ElasticDragDismissFrameLayout.SystemChromeFader(this){
    
                @Override
                public void onDrag(float elasticOffset, float elasticOffsetPixels, float rawOffset, float rawOffsetPixels) {
                    super.onDrag(elasticOffset, elasticOffsetPixels, rawOffset, rawOffsetPixels);
                    //do something
                }
    
                @Override
                public void onDragDismissed() {
                    super.onDragDismissed();
                    //do something
                }
            });

属性设置

属性名 作用 备注
dragDismissScale 滑动时布局的缩放比例 值为1时不缩放
dragDismissDistance 滑动消失的距离 当dragDismissFraction>0时,dragDismissDistance = height * dragDismissFraction;
dragDismissFraction 滑动消失的比例 大于0时,会影响dragDismissDistance的设置
dragElasticity drag回弹比例设置 影响回调效果
