ScrollView在相对布局中不起作用

Question

I'm working on a Login page for my app . The ScrollView isn't working and I'm unable to find out why. I've tried changing the layout_height of ScrollView to wrap_content and some arbitrary value like 900dp and same with the relative layout inside but still no luck. When the soft keyboard appears and I fill in details in say 1st editText view and want to scroll down to fill the second one without closing the Soft Keyboard. The page isn't scrolling. Here is the Code

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:fillViewport="true">

<RelativeLayout
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:paddingBottom="@dimen/activity_vertical_margin"
 android:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin" >

<TextView
    android:id="@+id/register"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/textView4"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="14dp"
    android:linksClickable="true"
    android:text="New to scheduLAWyer ? Sign Up" />

<Button
    android:id="@+id/login"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/register"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_marginBottom="14dp"
    android:text="Login" />

<TextView
    android:id="@+id/textView4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="28dp"
    android:linksClickable="true"
    android:text="Forgot Password" />

<ImageView
    android:id="@+id/imageView123"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:src="@drawable/schedulawyer" />

<LinearLayout
    android:id="@+id/lll"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/login"
    android:layout_alignRight="@+id/login"
    android:layout_below="@+id/imageView123"
    android:background="@drawable/rounded_corner"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="Email/Phone"
        android:singleLine="true" >

        <requestFocus />
    </EditText>

    <EditText
        android:id="@+id/editText2"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="Password"
        android:inputType="textPassword" />
</LinearLayout>

</RelativeLayout>

</ScrollView>

Answer 1

Okay I solved it myself. The problem was if an background image is added the page won't scroll until the image is bigger than the device size

Answer 2

Just wrap your RelativeLayout within one LinearLayout with android:layout_height="fill_parent" . That will give the ScrollView content to expand to.

The other, somewhat awkward approach could be to do it programmatically -- as described in this answer .

Answer 3

将RelativeLayout的高度更改为wrap_content 。

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="15dp" >

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

Try this and see what happens...

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin" >

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

        <TextView
            android:id="@+id/register"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_above="@+id/textView4"
            android:layout_centerHorizontal="true"
            android:layout_marginBottom="14dp"
            android:linksClickable="true"
            android:text="New to scheduLAWyer ? Sign Up" />

        <Button
