Android学习——HorizontalScollview水平滚动控件

HorizatalScollView控件只是支持水平滚动，而且它只能包含一个控件，通常是在<HorizatalScollView>标签中定义一个<LinearLayout>

标签并且在<LinearLayout>标签中android:orientation属性值设置为horization.然后在<LinearLayout>标签中放置多个控件，如果<LinearLayout>标签中的控件所占的总宽度超出屏幕的宽度，就会出现滚动效果。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
   >

    <HorizontalScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/horizontalScrollView"
        android:fadingEdge="horizontal"
        android:layout_gravity="center_horizontal" >
        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="horizontal"
            >
            <ImageView
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:src="@drawable/userhead"
                />
            <ImageView
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:src="@drawable/userhead"
                />
            <ImageView
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:src="@drawable/userhead"
                />
            <ImageView
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:src="@drawable/userhead"
                />
            </LinearLayout>

        </HorizontalScrollView>
</LinearLayout>

效果图如下，左右即可滑动图片
