今天開(kāi)發(fā)時(shí)变秦，遇到了幾個(gè)ScrollView與RecyclerView嵌套導(dǎo)致的問(wèn)題坦喘。

1. 進(jìn)入頁(yè)面時(shí)，layout沒(méi)有置頂

進(jìn)入頁(yè)面.jpeg

root cause: 由于在ScrollView內(nèi)嵌套了RecyclerView婉商，導(dǎo)致RecyclerView獲取到了焦點(diǎn)
solution: 使ScrollView包裹的View獲取到焦點(diǎn)
如下所示坟桅，在LinearLayout里增加 android:focusable="true"和 android:focusableInTouchMode="true"這兩個(gè)屬性

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:orientation="vertical">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="35sp"
            android:text="乘機(jī)人"/>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:paddingLeft="15dp">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycler_flight_order_detail"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

        </LinearLayout>
    </LinearLayout>
</ScrollView>

2.RecyclerView顯示不全

root cause: 可能是RecyclerView的onMeasure問(wèn)題
solution1: 重寫(xiě)LinearLayoutManager璃氢，可能可以解決
solution2: 使用NestScrollView哟玷，而不是ScrollView

<?xml version="1.0" encoding="utf-8"?>
<!-- 使用NestedScrollView 而不是ScrollView, 解決ScrollView嵌套R(shí)ecyclerView，導(dǎo)致RecyclerView顯示不全問(wèn)題 -->
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:orientation="vertical">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textSize="35sp"
            android:text="乘機(jī)人"/>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:paddingLeft="15dp">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycler_flight_order_detail"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

        </LinearLayout>
    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

3.NestedScrollView與RecyclerView滑動(dòng)沖突

root cause: NestedScrollView與RecyclerView嵌套
solution: recyclerView.setNestedScrollingEnabled(false);
reference: http://www.reibang.com/p/791c0a4acc1c

    @Override
    protected void initView() {
        mAdapter = new PassengerInfoAdapter();
        RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_flight_order_detail);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.addItemDecoration(new ListDivider(this, ListDivider.HORIZONTAL_LIST, R.drawable.passenger_info_divider));

        // 修復(fù)NestedScrollView與RecyclerView滑動(dòng)沖突
        recyclerView.setNestedScrollingEnabled(false);
        recyclerView.setAdapter(mAdapter);
    }
