Android:ScrollView中的RelativeLayout

Question

我有一个RelativeLayout多个ImageViews,当我转过屏幕时,ImageViews变得混乱.所以我决定把它包装成一个ScrollView.但是ScrollView不起作用!

任何人都可以帮助我吗？我知道正确的方法是设计一个GridView或者ListView,但由于我有一些问题,没有人回答我,我决定这样做.

这是我的xml代码:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ScrollView01"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    android:scrollbars="none" >

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/continuePizza"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:text="continue" />

    <Button
        android:id="@+id/finishP"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/continuePizza"
        android:layout_alignParentLeft="true"
        android:text="finish" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="16dp"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageView1"
        android:layout_marginLeft="18dp"
        android:layout_toRightOf="@+id/imageView1"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/imageView1"
        android:layout_marginTop="18dp"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/imageView3"
        android:layout_centerVertical="true"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageView3"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/imageView5"
        android:layout_marginTop="17dp"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView7"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/imageView2"
        android:layout_alignTop="@+id/imageView5"
        android:layout_marginLeft="10dp"
        android:src="@drawable/download" />

    <ImageView
        android:id="@+id/imageView8"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/imageView7"
        android:layout_alignTop="@+id/imageView3"
        android:src="@drawable/download" />

</RelativeLayout>
</ScrollView>

Answer 1

简单解决方案,只需将android:fillViewport ="true"添加到Scrollview,如:

<ScrollView 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

<RelativeLayout ....... />

</ScrollView>

Answer 2

我在Scroll View中遇到了相对布局的相同问题以克服这个问题我用线性布局包裹了我的相对布局,尝试这样并且还从相对布局中移除方向

<?xml version="1.0" encoding="utf-8"?>


<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ScrollView01"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:scrollbars="none" >

<LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent">


<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>


<Button
    android:id="@+id/continuePizza"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:text="continue" />

<Button
    android:id="@+id/finishP"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/continuePizza"
    android:layout_alignParentLeft="true"
    android:text="finish" />

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"

    android:src="@drawable/download" />

<ImageView
    android:id="@+id/imageView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignTop="@+id/imageView1"
    android:layout_marginLeft="18dp"
    android:layout_toRightOf="@+id/imageView1"
    android:src="@drawable/download" />

<ImageView
    android:id="@+id/imageView3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/imageView1"

<ImageView
    android:id="@+id/imageView5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/imageView3"

<ImageView
    android:id="@+id/imageView4"

    android:layout_height="wrap_content"
    android:layout_below="@+id/imageView5"
    android:layout_marginTop="17dp"
    android:src="@drawable/download" />

<ImageView
    android:id="@+id/imageView7"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/imageView2"
    android:layout_alignTop="@+id/imageView5"
    android:layout_marginLeft="10dp"
    android:src="@drawable/download" />
<ImageView
    android:id="@+id/imageView8"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
