另一个 ScrollView 中的Android ScrollView 不滚动

Question

我正在尝试将 ScrollView 放在另一个 ScrollView 中，并尝试了在此站点上找到的答案，但它似乎仍然无法完全正常工作。这是 XML:

 <ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:focusableInTouchMode="false" >

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

        <TextView
            android:id="@+id/textViewDirectoryDetailName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Name"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="@color/red" />

        <LinearLayout
            android:id="@+id/linearLayoutDirectoryDetailContainImage"
            android:layout_width="300dp"
            android:layout_height="200dp"
            android:layout_gravity="center_vertical|center_horizontal"
            android:background="@drawable/general_image"
            android:gravity="center"
            android:orientation="vertical" >
        </LinearLayout>

        <ScrollView
            android:id="@+id/scrollView2"
            android:layout_width="match_parent"
            android:layout_height="100dp"
            android:focusableInTouchMode="false" >

            <TextView
                android:id="@+id/textViewDirectoryDescription"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dp"
                android:autoLink="phone"
                android:text="098 123 45 678"
                android:textAppearance="?android:attr/textAppearanceLarge" />
        </ScrollView>

这里是 Java 代码:

parentScrollView = (ScrollView) findViewById(R.id.scrollView1);
    childScrollView = (ScrollView) findViewById(R.id.scrollView2);

    parentScrollView.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View p_v, MotionEvent p_event) {
            childScrollView.getParent().requestDisallowInterceptTouchEvent(
                    false);
            // We will have to follow above for all scrollable contents
            return false;
        }
    });
    childScrollView.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View p_v, MotionEvent p_event) {
            // this will disallow the touch request for parent scroll on
            // touch of child view
            p_v.getParent().requestDisallowInterceptTouchEvent(true);
            return false;
        }
    });
    // We will have to follow above for all child scrollable contents

似乎发生了这样的事情:当我在 TextView 中有文本时，它似乎根本不允许我滚动它。它只是滚动父级。但是当我没有文本并且我触摸子 ScrollView 时，它不会滚动父级，所以我猜它正在工作。但是你有什么想法为什么当我有文本时它不起作用？

您应该使用 NestedScrollView .

<android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            >
            <!-- -->
</android.support.v4.widget.NestedScrollView>
