Android ScrollView + ListView嵌套使用

首先需要自定义ListView

public class MyListView extends ListView {
    public MyListView(Context context) {
        super(context);
    }

    public MyListView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyListView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    public MyListView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }
    /**
     *重写该方法，达到使ListView适应ScrollView的效果
     */
    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int mExpandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, mExpandSpec);
    }

}

 布局文件

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:fillViewport="true"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="match_parent"
        android:orientation="vertical"
        android:focusableInTouchMode="true"
        android:focusable="true"
        android:descendantFocusability="beforeDescendants"
        android:layout_height="match_parent">
        <LinearLayout
            android:layout_width="match_parent"
            android:background="@color/gray_background"
            android:orientation="horizontal"
            android:gravity="center_vertical"
            android:layout_gravity="center_vertical"
            android:layout_marginStart="5dp"
            android:layout_marginEnd="5dp"
            android:layout_height="40dp">
            <TextView
                android:layout_width="wrap_content"
                android:text="品名："
                android:gravity="center_vertical"
                android:textColor="@color/gray_font"
                android:layout_height="match_parent" />
            <TextView
                android:layout_width="wrap_content"
                android:text="规格"
                android:textColor="@color/gray_font"
                android:gravity="center_vertical"
                android:layout_height="match_parent" />
            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center_vertical"
                android:src="@drawable/dropdown_gray"
                />
        </LinearLayout>
        <MyListView
            android:id="@+id/listview"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        </MyListView>
    </LinearLayout>
</ScrollView>

 其中  android:fillViewport="true" 让listview 填充屏幕

而下面这3行，是防止自动跳转到listview的第一行

    android:focusableInTouchMode="true"
        android:focusable="true"
        android:descendantFocusability="beforeDescendants"
