我的xml布局有问题。 我想用xml制作我的布局,“simplemessage”会粘在顶部,“textchange”将填充并居中在屏幕中间,而“hiraganaconfbutton”会粘在底部,我尝试重力和居中,但是某些原因,它不起作用
提前感谢您的帮助
这是我的xml布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<TextView
android:id="@+id/simplemessage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/guess"
android:textSize="19sp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<TextView
android:id="@+id/textchange"
android:layout_width="wrap_content"
android:layout_height="392dp"
android:text="@string/a"
android:textSize="60sp" />
</LinearLayout>
<Button
android:id="@+id/hiraganaconfbutton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/confirm" />
</LinearLayout>

可以这样吗?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<TextView
android:id="@+id/simplemessage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/guess"
android:gravity="center"
android:textSize="19sp"
android:layout_alignParentTop="true"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/simplemessage"
android:layout_above="@+id/hiraganaconfbutton"
android:orientation="horizontal" >
<TextView
android:id="@+id/textchange"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="@string/a"
android:textSize="60sp" />
</LinearLayout>
<Button
android:id="@+id/hiraganaconfbutton"
android:layout_width="match_parent"

使用相对布局如下:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="@+id/simplemessage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/guess"
android:gravity="center"
android:textSize="19sp"
android:layout_alignParentTop="true"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/simplemessage"
android:layout_above="@+id/hiraganaconfbutton"
android:orientation="horizontal" >
<TextView
android:id="@+id/textchange"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="@string/a"
android:textSize="40sp" />
</LinearLayout>
<Button
android:id="@+id/hiraganaconfbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center"
android:text="@string/confirm" />
</RelativeLayout>
