安卓ScrollView嵌套RecyclerView，GridView，ViewPager冲突解决

如题，就把项目中常见的这几个冲突总结下吧，记性不太好，还是写下来好了。

ScrollView嵌套RecyclerView

滑动不流畅冲突：在RecyclerView属性中加入
android:nestedScrollingEnabled="false"
使recyclerview的滑动跟随scrollveiw

scrollview中组件不能充满：
Android:fillViewport="true"
允许Scrollview中的组件填充它

RecyclerView显示在布局顶部：
mRecyclerTest.setFocusable(false);//失去焦点

ScrollView嵌套GridView、ListView

只显示一行：自定义一个gridview重新绘制item高度

public class MyGridView extends GridView {    public MyGridView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public MyGridView(Context context) {        super(context);    }    public MyGridView(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);    }    @Override    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,                MeasureSpec.AT_MOST);        super.onMeasure(widthMeasureSpec, expandSpec);    }}

GridView顶部显示问题：
在GridView的父View中加入属性

android:focusable="true"android:focusableInTouchMode="true"

ScrollView嵌套ViewPager

viewpager不显示：重新定义一个ViewPager

public class ScrollViewPager extends ViewPager{    public ScrollViewPager(Context context) {        super(context);    }    public ScrollViewPager(Context context, AttributeSet attrs) {        super(context, attrs);    }    @Override    protected void onMeasure(int widthMeasureSpec, int 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);    }}

CollapsingToolbarLayout和GridView一起使用，滑动gridview无折叠效果

 ViewCompat.setNestedScrollingEnabled(mGridView,true);
