Android 折叠工具栏布局,其中Viewpager位于NestedScrollView中
我在嵌套的Scrollview中使用了嵌套的Scrollview和Viewpager的折叠工具栏布局 我有3个标签,这些标签有3个片段。这些片段正在使用RecyclerView设置数据 现在使用nestedScrollView和viewpager,当我滚动RecyclerView内容时,折叠效果不适用于此 我需要把NestedScrollView也,因为我有一些信息,我需要显示上面的标签 这是我的密码:Android 折叠工具栏布局,其中Viewpager位于NestedScrollView中,android,android-viewpager,android-collapsingtoolbarlayout,Android,Android Viewpager,Android Collapsingtoolbarlayout,我在嵌套的Scrollview中使用了嵌套的Scrollview和Viewpager的折叠工具栏布局 我有3个标签,这些标签有3个片段。这些片段正在使用RecyclerView设置数据 现在使用nestedScrollView和viewpager,当我滚动RecyclerView内容时,折叠效果不适用于此 我需要把NestedScrollView也,因为我有一些信息,我需要显示上面的标签 这是我的密码: <android.support.design.widget.AppBarLayout

如果您知道如何在android的NestedScrollview中实现Recyclerview,请帮助我,这样我就可以工作了。这里似乎已经回答了这个问题: 您还可以查看上述答案中提供的示例 作者创建了一个自定义NestedScrollView类,该类扩展了NestedScrollView,覆盖了onInterceptTouchEvent方法,如下所示:
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
final float x = ev.getX();
final float y = ev.getY();
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
xDistance = yDistance = 0f;
lastX = ev.getX();
lastY = ev.getY();
break;
case MotionEvent.ACTION_MOVE:
final float curX = ev.getX();
final float curY = ev.getY();
xDistance += Math.abs(curX - lastX);
yDistance += Math.abs(curY - lastY);
lastX = curX;
lastY = curY;
if (xDistance > yDistance)
return false;
}
return super.onInterceptTouchEvent(ev) || ev.getPointerCount() == 2;
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int height = 0;
for (int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if (h > height) height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
以及一个自定义ViewPager类,它扩展了ViewPager,覆盖了其onMeasure方法,如下所示:
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
final float x = ev.getX();
final float y = ev.getY();
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
xDistance = yDistance = 0f;
lastX = ev.getX();
lastY = ev.getY();
break;
case MotionEvent.ACTION_MOVE:
final float curX = ev.getX();
final float curY = ev.getY();
xDistance += Math.abs(curX - lastX);
yDistance += Math.abs(curY - lastY);
lastX = curX;
lastY = curY;
if (xDistance > yDistance)
return false;
}
return super.onInterceptTouchEvent(ev) || ev.getPointerCount() == 2;
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int height = 0;
for (int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if (h > height) height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
@覆盖
测量时的保护空隙(内部宽度测量等级、内部高度测量等级){
超级测量(宽度测量、高度测量);
整数高度=0;
对于(int i=0;i高度)高度=h;
}
heightMeasureSpec=MeasureSpec.MakeMasureSpec(高度,精确测量);
超级测量(宽度测量、高度测量);
}
最后,他在Coordinator布局中使用了以下两种方法:
<com.thelittlenaruto.supportdesignexample.customview.MyNestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<LinearLayout
android:id="@+id/lin"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:visibility="visible">
<com.thelittlenaruto.supportdesignexample.customview.WrapContentHeightViewPager
android:id="@+id/viewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</com.thelittlenaruto.supportdesignexample.customview.MyNestedScrollView>
