Android ScrollView 내장 ScrollView 스크롤 문제 해결 방법 원본 주소:http://trivedihardik.wordpress.com/2011/09/19/scrollview-inside-scrollview-scrolling-problem/ 기술 을 하 는 사람 은 얼마든지 E 문 을 읽 을 수 있 고 번역 도 하지 않 는 다. While designing rich layouts you might need to use two scrollview in your app. Well ideally its not advised to use two scrollview in a view. So try to avoid it. Why this problem occurs ? : When you put two scrollview android just get confused which scroll view is touched. So sometimes it gets unable to deliver touch event. But even if the requirement forces you to make such layouts. Try this… Say case is somewhat like this…. 

    <ScrollView

        android:id="@+id/parent_scroll"

        android:layout_width="match_parent"

        android:layout_height="0dp"

        android:layout_weight="1"

        android:background="@color/black"

        android:cacheColorHint="#00000000"

        android:fadingEdge="none"

        android:overScrollMode="never"

        android:scrollbars="none">



        <LinearLayout

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:gravity="center"

            android:orientation="vertical">

 





                <ScrollView

                    android:id="@+id/child_scroll"

                    android:layout_width="match_parent"

                    android:layout_height="wrap_content"

                    android:layout_toRightOf="@+id/TextView001"

                    android:cacheColorHint="#00000000"

                    android:fadingEdge="none"

                    android:overScrollMode="never"

                    android:scrollbars="none">



                    <TextView

                        android:id="@+id/tv_detail"

                        android:layout_width="match_parent"

                        android:layout_height="wrap_content"

                        android:padding="15dp"

                        android:textColor="@color/cbWhite"

                        android:textSize="@dimen/cb_textSize_big"/>

                </ScrollView>

 

 



        </LinearLayout>

    </ScrollView>

 
Step 1 : Provide unique id to both the scrollview. Step 2 : get reference of that two scrollview in your activity.  

    ScrollView parentScroll = (ScrollView) findViewById(R.id.parent_scroll);

    ScrollView childScroll = (ScrollView) findViewById(R.id.child_scroll);

 
Step 3: Now set touch listeners for both.  

        parentScroll.setOnTouchListener(new View.OnTouchListener() {



            public boolean onTouch(View v, MotionEvent event) {

                findViewById(R.id.child_scroll).getParent().requestDisallowInterceptTouchEvent(false);

                return false;

            }

        });

        childScroll.setOnTouchListener(new View.OnTouchListener() {



            public boolean onTouch(View v, MotionEvent event) {

                // Disallow the touch request for parent scroll on touch of child view

                v.getParent().requestDisallowInterceptTouchEvent(true);

                return false;

            }

        });

 
Done …
