有没有人想办法让reclerviews,AppbarLayouts和SwipeRefreshLayout在23.2上一起工作呢？我认为我使用的是一种非常标准的方法,但是当试图向上移动Recyclerview时,swiperefreshlayout一直抓住滚动手势.
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="?attr/toolbar_theme"
app:layout_scrollFlags="scroll|enterAlways"
android:elevation="4dp" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="@+id/fragment_container"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--fragment goes here -->
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
内有以下内容
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/swipe_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/window_background">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ProgressBar
android:id="@+id/progress_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
style="@style/Widget.AppCompat.ProgressBar.Horizontal"
android:layout_marginTop="-4dp"
android:layout_marginBottom="-8dp"
android:elevation="17dp"
android:indeterminate="true"
android:visibility="invisible" />
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</FrameLayout>
</android.support.v4.widget.SwipeRefreshLayout>
解决方法

ImprovedSwipeLayout.java
public class ImprovedSwipeLayout extends SwipeRefreshLayout {
private static final String TAG = ImprovedSwipeLayout.class.getCanonicalName();
private int mScrollableChildId;
private View mScrollableChild;
public ImprovedSwipeLayout(Context context) {
this(context,null);
}
public ImprovedSwipeLayout(Context context,AttributeSet attrs) {
super(context,attrs);
TypedArray a = context.obtainStyledAttributes(
attrs,R.styleable.ImprovedSwipeLayoutAttrs);
mScrollableChildId = a.getResourceId(R.styleable.ImprovedSwipeLayoutAttrs_scrollableChildId,0);
mScrollableChild = findViewById(mScrollableChildId);
a.recycle();
}
@Override
public boolean canChildScrollUp() {
ensureScrollableChild();
if (android.os.Build.VERSION.SDK_INT < 14) {
if (mScrollableChild instanceof AbsListView) {
final AbsListView absListView = (AbsListView) mScrollableChild;
return absListView.getChildCount() > 0
&& (absListView.getFirstVisiblePosition() > 0 || absListView.getChildAt(0)
.getTop() < absListView.getPaddingTop());
} else {
return mScrollableChild.getScrollY() > 0;
}
} else {
return ViewCompat.canScrollVertically(mScrollableChild,-1);
}
}
private void ensureScrollableChild() {
if (mScrollableChild == null) {
mScrollableChild = findViewById(mScrollableChildId);
}
}
}
它是从http://nerd-is.in/2014-09/add-multi-child-view-in-swiperefreshlayout/
创建一个View extends SwipeRefreshLayout和自定义canChildScrollUp.
