Scrollview无法在Android底片中滚动

问题描述 投票:17回答:5

我在Android支持中尝试了新的BottomSheet。在BottomSheet里面我放了一个TextView和一个ScrollViewBottomSheetshowing就好了,我发现的唯一问题是ScrollView中的BottomSheet不滚动。每次我尝试滚动时,滚动的主要活动中的布局或BottomSheet从崩溃状态改变状态以扩展。

这是我的Activity类代码的片段:

private BottomSheetBehavior behavior;
View bottomSheet;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    setTextViewOnClickListener(this, findViewById(R.id.parentLayout));

    CoordinatorLayout coordinatorLayout = (CoordinatorLayout) findViewById(R.id.main_content);

    // The View with the BottomSheetBehavior
    bottomSheet = coordinatorLayout.findViewById(R.id.bottom_sheet);
    behavior = BottomSheetBehavior.from(bottomSheet);
    behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            // React to state change

        }


        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {
            // React to dragging events
        }
    });

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.tv1:
            setTextViewHeader("Header1");
            setTextViewContent("Long_Text_1");

            break;

        case R.id.tv2:
            setTextViewHeader("Header2");
            setTextViewContent("Long_Text_2");

            break;

        case R.id.tv3:
            setTextViewHeader("Header3");
            setTextViewContent("Long_Text_3");

            break;

        default:
            break;
    }

    behavior.setPeekHeight(100);
    behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
    behavior.setHideable(true);

    bottomSheet.requestLayout();
}

这是我的布局XML:

希望你现在想出来,但将View bottomSheet改为NestedScrollView bottomSheet

除了“jobbert”的答案:

如果你总是返回“假”,可能会发生底片根本不起作用。当我在底部的coordinatorlayout中使用一个viewpager时,这发生在我身上。要实际修复它,需要检查触摸是否在nestedscrollview内。这可以很容易地计算出来,并得出最通用的解决方案:

 override fun onInterceptTouchEvent(parent: CoordinatorLayout, child: V, event: MotionEvent): Boolean {

    val nested = child.findViewById<NestedScrollView>(R.id.nested) //NestedScrollView
    var x = event.x
    var y = event.y

    val position = IntArray(2)
    nested.getLocationOnScreen(position)

    var nestedX = position[0]
    var nestedY = position[1]


    var boundLeft = nestedX
    var boundRight = nestedX + nested.width
    var boundTop = nestedY
    var boundBottom = nestedY + nested.height


    if ((x > boundLeft && x < boundRight && y > boundTop && y < boundBottom) || event.action == MotionEvent.ACTION_CANCEL) {
        //Touched inside of the scrollview-> pass the touch event to the scrollview
        return false
    }



    //touched outside, use the parents computation to make the bottomsheet work
    return super.onInterceptTouchEvent(parent, child, event)

}

使用下面的自定义底部表格行为

public class CustomBottomSheetBehaviour<V extends View> extends BottomSheetBehavior {
    public CustomBottomSheetBehaviour() {
        super();
    }

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

    @Override
    public boolean onInterceptTouchEvent(CoordinatorLayout parent, View child, MotionEvent event) {
        return false;
    }
}

我通过做下面的事情解决了这个问题 -

  • 第一:当您使用CoordinatorLayout而不是用户NestedScrollView时,不要使用ScrollView,它使用CoordinatorLayout可以更好地工作。
  • 第二:在底部放置一个android:layout_height的空白视图,但在你的内部NestedScrollView例如 - <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="vertical"> <ImageView android:background="@drawable/username" android:id="@+id/userImage_info_search" android:layout_gravity="center" android:layout_height="100dp" android:layout_margin="20dp" android:layout_width="100dp" /> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent"> <View android:background="@android:color/black" android:layout_height="1dp" android:layout_width="match_parent"></View> </LinearLayout> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="horizontal" android:padding="10dp" android:weightSum="3"> <TextView style="@style/Bottomsheetstyle" android:id="@+id/txtNamelabel_info_search" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="1" android:layout_width="0dp" android:text="Name" /> <TextView style="@style/Bottomsheetstyle" android:id="@+id/txtName_info_search" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="2" android:layout_width="0dp" android:text="" /> </LinearLayout> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent"> <View android:background="@android:color/black" android:layout_height="1dp" android:layout_width="match_parent"></View> </LinearLayout> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="horizontal" android:padding="10dp" android:weightSum="3"> <TextView style="@style/Bottomsheetstyle" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="1" android:layout_width="0dp" android:text="Number" /> <LinearLayout android:layout_height="wrap_content" android:layout_weight="2" android:layout_width="0dp" android:orientation="horizontal"> <TextView style="@style/Bottomsheetstyle" android:gravity="center_vertical" android:id="@+id/txtNumber_info_search" android:layout_gravity="center_vertical" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="1.4" android:layout_width="0dp" android:text="+XX (XXX) XXX-XXXX" /> <ImageView android:background="@drawable/call_save" android:id="@+id/call_info_search" android:layout_height="wrap_content" android:layout_weight="0.3" android:layout_width="0dp" /> <View android:layout_gravity="center" android:layout_height="5dp" android:layout_width="5dp"></View> <ImageView android:background="@drawable/comment_save" android:id="@+id/sms_info_search" android:layout_height="wrap_content" android:layout_weight="0.3" android:layout_width="0dp" /> </LinearLayout> </LinearLayout> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent"> <View android:background="@android:color/black" android:layout_height="1dp" android:layout_width="match_parent"></View> </LinearLayout> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent" android:orientation="horizontal" android:padding="10dp" android:weightSum="3"> <TextView style="@style/Bottomsheetstyle" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="1" android:layout_width="0dp" android:text="Email" /> <TextView style="@style/Bottomsheetstyle" android:id="@+id/txtEmail_info_search" android:layout_gravity="center" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:layout_weight="2" android:layout_width="0dp" android:text="" /> </LinearLayout> <LinearLayout android:layout_height="wrap_content" android:layout_width="match_parent"> <View android:background="@android:color/black" android:layout_height="1dp" android:layout_width="match_parent"></View> </LinearLayout> <View android:background="@android:color/transparent" android:layout_height="@dimen/somedp" android:layout_width="match_parent" />

这对我有用,尝试使用第一个scrollView然后线性或相对布局,并使用它也使用它上面的嵌套滚动视图

<RelativeLayout
    android:id="@+id/bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="250dp"
    app:behavior_hideable="true"
    app:elevation="4dp"
    android:background="@color/colorPrimaryDark"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
    android:clipToPadding="true">


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


            <TextView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:padding="16dp"
                android:text="oh hello this is dummy data"
                android:textColor="#FFFFFF"
                android:textSize="20sp" />

            <ImageView
                android:id="@+id/imageView2"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:srcCompat="@mipmap/ic_launcher" />
            <ImageView
                android:id="@+id/"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:srcCompat="@mipmap/ic_launcher" />
            <ImageView
                android:id="@+id/"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:srcCompat="@mipmap/ic_launcher" />
            <ImageView
                android:id="@+id/"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:srcCompat="@mipmap/ic_launcher" />

            <ImageView
                android:id="@+id/"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:srcCompat="@mipmap/ic_launcher" />
        </LinearLayout>
    </ScrollView>

@Aghil C M回答有效,但由于自动翻译无法解决问题而将其翻译成Kotlin。

class CustomBottomSheetBehaviour<V : View> : BottomSheetBehavior<V> {
    constructor() : super()

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs)

    override fun onInterceptTouchEvent(parent: CoordinatorLayout?, child: V, event: MotionEvent?): Boolean {
        return false
    }
}
