recyclerview

SwipeRefreshLayout 与 CoordinatorLayout 嵌套刷新 1.设置 mSwipeRefreshLayout.setOnRefreshListener(this); 2. 动态设置SwipeRefreshLayout的是否可以刷新 setEnable(boolean isEnable); 3. 设置SwipRefreshLayout刷新图标的位置 setProgressViewOffset(true, -20, 100); 4. 监听 AppBarLayout Offset 变化，动态设置 SwipeRefreshLayout 是否可用 appBarLayout = (AppBarLayout) findViewById(R.id.appbar_layout)； appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() { @Override public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) { if (verticalOffset >= 0) { mSwipeRefreshLayout.setEnabled(true); } else {

背景：高版本的编译环境中，SwipeRefreshLayout和RecyclerView并不存在滑动冲突问题，而我恰恰手里有个target是22的项目，当我按照正常的逻辑写完界面后，使用app发现滑动整个列表时两个控件发生冲突，本着快速解决上线任务的原则，直接百度. 网上的完美解决方案如下 ： RecyclerView.OnScrollListener(){ @Override public void onScrolled(RecyclerView recyclerView, int dx, int dy) { int topRowVerticalPosition = (recyclerView == null || recyclerView.getChildCount() == 0) ? 0 : recyclerView.getChildAt(0).getTop(); swipeRefreshLayout.setEnabled(topRowVerticalPosition >= 0); } @Override public void onScrollStateChanged(RecyclerView recyclerView, int newState) { super.onScrollStateChanged(recyclerView, newState); } });

View getHeightView = new View(context); recycler_view.addOnScrollListener(new RecyclerView.OnScrollListener() { @Override public void onScrollStateChanged(RecyclerView recyclerView, int newState) { super.onScrollStateChanged(recyclerView, newState); if (newState == RecyclerView.SCROLL_STATE_DRAGGING) { SoftPanUtil.hideSoftKeyboard(ChatDetailActivity.this); if (emojiKeyboard != null) { emojiKeyboard.hide(); } } } @Override public void onScrolled(RecyclerView recyclerView, int dx, int dy) { super.onScrolled(recyclerView, dx, dy); getHeightView.scrollBy(0, dy); LogUtils.e("滑动高度" + getHeightView

一、效果图 二、实现步骤 1.添加依赖库 (Android/Gradle Scripts/build.gradle(Module:app)) compile 'com.android.support:recyclerview-v7:26.+' /* 版本号与 compile 'com.android.support:appcompat-v7:26.+' ，此句版本号为 26 .+ */ 2.RecyclerView布局 （activity_main.xml） <?xml version="1.0" encoding="utf-8"?> < RelativeLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "match_parent" android:layout_height = "match_parent" > < android.support.v7.widget.RecyclerView android:id = "@+id/recyclerview" android:background = "#EEEEEE" android:scrollbars = "vertical" android:layout_width = "match

Recyclerview下面跟随着控件 效果 代码 注意点 推论 代码 效果 最后是实现了 RecyclerView 下面的控件会跟随着内容增加而下滑，并且最后超过屏幕时，下面的控件会粘在屏幕底部 代码 < LinearLayout xmlns : android = "http://schemas.android.com/apk/res/android" android : orientation = "vertical" android : id = "@+id/activity_main" android : layout_width = "match_parent" android : layout_height = "wrap_content" > < android . support . v7 . widget . RecyclerView android : layout_width = "match_parent" android : layout_height = "0dp" android : layout_weight = "1" > < / android . support . v7 . widget . RecyclerView > < LinearLayout android : layout_width = "match_parent"

在dependencies中写 implementation ‘androidx.recyclerview:recyclerview:1.0.0’ 来源： https://blog.csdn.net/csbn123456789/article/details/102760889

Android添加依赖recycleview错误 在添加依赖的时候就发现自己出现这个错 ERROR: Failed to resolve: com.android.support:recycleview-v7:29.2.1 Show in Project Structure dialog Affected Modules: app 后面检查自己那条语句，语法好像已经变了 implementation'com.android.support:recycleview-v7:29.2.1' 把这句话换成这句话就可以成功创建 implementation'androidx.recyclerview:recyclerview:1.0.0' 最后syn now 就成功了 来源： https://blog.csdn.net/weixin_45598936/article/details/102757919
