如何防止ScrollView拦截其背后视图的单击/触摸事件? [英] How to prevent ScrollView from intercepting click/touch events of the view behind it?

问题描述

我在FrameLayout中有一个ScrollView和ImageView.ImageView位于滚动视图的后面

I have a ScrollView and an ImageView inside a FrameLayout. The ImageView is behind the scroll view

我的ScrollView有一个透明空间(LinearLayout s_layout_transparent，高度为925px).

My ScrollView have a transparent space (LinearLayout s_layout_transparent with 925px height).

因此可以在此透明空间中看到我的ImageView ，但不能单击 .

So my ImageView can be seen through this transparent space but can not be click.

我尝试添加一些值(android:clickable ="false" android:focusable ="android:focusableInTouchMode =" false)滚动视图以防止其拦截ImageView，但这根本不起作用.

I have tried to add some value (android:clickable="false" android:focusable=" android:focusableInTouchMode="false") to scroll view to prevent it intercepts the click envent of the ImageView but this not work at all.

这是我的布局:

<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent">
<LinearLayout
        android:gravity="top|center_horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingRight="10dp"
        >
    <ImageView
            android:visibility="visible"
            android:id="@+id/s_imgv_splash"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/temp_detail_screen_splash"
            android:adjustViewBounds="true"
            android:scaleType="fitXY"/>
</LinearLayout>
<com.dreambox.android.saven.Views.ScrollView
        android:id="@+id/s_scrollview_event_detail"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scrollbars="none"
        android:visibility="visible"
        android:clickable="false"
        android:focusable="false"
        android:focusableInTouchMode="false"
        >
    <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clickable="false"
            android:focusableInTouchMode="false"
            android:focusable="false">
        <LinearLayout
                android:id="@+id/s_layout_transparent"
                android:layout_gravity="center_vertical"
                android:layout_width="match_parent"
                android:layout_height="925px"
                android:orientation="horizontal"
                android:background="@color/trasparent"
                android:clickable="false"
                android:focusableInTouchMode="false"
                android:focusable="false">
        </LinearLayout>
        <LinearLayout...>
        <LinearLayout...>
    </LinearLayout>
</com.dreambox.android.saven.Views.ScrollView>
</FrameLayout>

推荐答案

如果您可以用一个空视图填充透明部分(我们称其为dummyView)，则可以执行类似的操作...

if you can fill the transparent parts with an empty view (lets call it dummyView), you can do something like...

dummyView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View view, MotionEvent event) {
        // pass on the touch event to the ImageView
        s_imgv_splash.dispatchTouchEvent(event);
        // returning true because we handled the event
        return true;
    }
});
