滚动视图无响应

Question

Works great for portrait mode. If I go on landscape mode I have my activity drawn in the center of screen which leaves blank screen on both left and right side. If I drag by keeping mouse on views (ie center)the scroll takes effect. If I drag on empty right side no scrolling ? why ?

posting my layout xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ScrollView
        android:id="@+id/enter_pin_scroll"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scrollbarStyle="outsideOverlay" >

        <RelativeLayout
            android:id="@+id/enter_pin_header_layout"
            android:layout_width="@dimen/pin_inset_region_width"
            android:layout_height="@dimen/pin_inset_region_height"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_horizontal" >

            <LinearLayout

Answer 1

将滚动视图的宽度设置为fillparent不换行

android:layout_width="fill_parent"

Answer 2

Presumably, your ScrollView's width is set to wrap_content and thus, touch events outside of the dial pad are not taking any effect.

You can fix this by changing,

<ScrollView 
    android:layout_width="wrap_content" 
    ... />

to,

<ScrollView 
    android:layout_width="match_parent" 
    ... />

If every view is stored in the ScrollView, why not remove the RelativeLayout ? Have directly :

<ScrollView
    android:id="@+id/enter_pin_scroll"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scrollbarStyle="outsideOverlay" >

    <RelativeLayout
        android:id="@+id/enter_pin_header_layout"
        android:layout_width="@dimen/pin_inset_region_width"
        android:layout_height="@dimen/pin_inset_region_height"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal" >

If you want to keep it :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

Set the layout_height to fill_parent.
