android - 旋转屏幕时没有滚动条

Question

大家好，我有两个问题：

1. 旋转屏幕（横向）时，我错过了我的控件。
2. 我有返回和下一步按钮。我想把它们放在我活动的最后。怎么做？

我的代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".TeamActivity" >

   <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" 
        android:layout_marginTop="10dp">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Home Club" />

        <EditText
            android:id="@+id/editText1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:ems="10" >

            <requestFocus />
        </EditText>
    </LinearLayout>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"

            android:ems="10" />
    </LinearLayout>
    <LinearLayout

        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Away Club" />

            android:onClick="OpenVenueActivity"
            android:text="Back" />
    </RelativeLayout>

</LinearLayout>

请帮助。

Answer 1

Surround the entire top-level

<LinearLayout>
</LinearLayout>

in a

<ScrollView>
    (Your <LinearLayout></LinearLayout> goes here)
</ScrollView>

But you could also consider a res/layout-land/mylayout.xml (matching res/layout/mylayout.xml) to use a different layout in landscape view that perhaps avoids the need to scroll.
