Java – how to set onclicklistener for Scrollview?

I'm developing an Android project with viewpager I wrote an adapter for my viewpager. My adapter consists of s Scrollview and some views inside

I think something will happen when the user clicks on the scroll view (I also wrote this section and tested it and it works)

I implemented onclicklistener for my Scrollview, but it won't be triggered when the user clicks it

I've read this, but it doesn't work for me

My onclicklistener code is right here

rootView = inflater.inflate(R.layout.level_selector_list_view_adapter,container,false);
ScrollView scroll = (ScrollView) rootView.findViewById(R.id.level_selector_view_scroll_view);

scroll.setOnClickListener(new OnClickListener()
{
        @Override
        public void onClick(View arg0)
        {
            Log.e(MainActivity.WATERMELON_TAG,"Click!!!");
        }
});

My layout code is as follows:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="@dimen/level_selector_values_main_page_view_pager_width"
android:layout_height="wrap_content"
android:orientation="vertical" >

<ScrollView
    android:id="@+id/level_selector_view_scroll_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:clickable="true"
    tools:ignore="UselessParent" >

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clickable="false"
        tools:ignore="UselessParent" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:clickable="false"
            android:orientation="vertical" >

            <ImageView
                android:id="@+id/level_selector_view_pager_adapter_level_logo"
                android:layout_width="@dimen/level_selector_values_view_pager_adapter_level_logo_width"
                android:layout_height="@dimen/level_selector_values_view_pager_adapter_level_logo_height"
                android:layout_gravity="center_horizontal"
                android:layout_marginTop="@dimen/level_selector_values_view_pager_adapter_level_logo_top_margin"
                android:clickable="false"
                android:scaleType="fitXY"
                tools:ignore="ContentDescription" />

            <TextView
                android:id="@+id/level_selector_view_pager_adapter_level_name"
                android:layout_width="@dimen/level_selector_values_view_pager_adapter_level_name_width"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:layout_marginTop="@dimen/level_selector_values_view_pager_adapter_level_name_top_margin"
                android:clickable="false"
                android:gravity="center"
                android:textColor="@color/level_selector_values_level_name_font_color"
                android:textSize="@dimen/level_selector_values_level_name_font_size" />

            <TextView
                android:id="@+id/level_selector_view_pager_adapter_level_score"
                android:layout_width="@dimen/level_selector_values_view_pager_adapter_level_score_width"
                android:layout_height="wrap_content"
                android:layout_gravity="center_horizontal"
                android:layout_marginTop="@dimen/level_selector_values_view_pager_adapter_level_score_top_margin"
                android:clickable="false"
                android:gravity="center"
                android:textColor="@color/level_selector_values_level_name_font_color"
                android:textSize="@dimen/level_selector_values_font_size" />
        </LinearLayout>

        <ImageView
            android:id="@+id/level_selector_view_pager_adapter_lock"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center"
            android:alpha="0.75"
            android:clickable="false"
            android:scaleType="fitXY"
            android:src="@drawable/lock"
            tools:ignore="ContentDescription" />
    </FrameLayout>
</ScrollView>

Solution

Child views of Scrollview are consuming the click events you performed on Scrollview

The solution to this problem is to set onclicklister as a direct child of Scrollview, that is, FrameLayout. In your case

Don't forget to set the layout to clickable

In addition, I don't recommend using FrameLayout because it's just a useless container Instead, just make the LinearLayout of the child of the current FrameLayout the next child of Scrollview
