RecyclerView 占据所有屏幕空间 [英] RecyclerView takes up all screenspace
问题描述
所以我在布局文件中遇到了 RecyclerView 的问题
So I'm having some trouble with a RecyclerView in a layout file
这是:
<android.support.v7.widget.RecyclerView
android:id="@+id/chat_listview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingRight="@dimen/abc_action_bar_default_padding_material"
android:paddingLeft="@dimen/abc_action_bar_default_padding_material"
/>
<LinearLayout
android:layout_below="@id/chat_listview"
android:layout_width="match_parent"
android:layout_height="@dimen/bottom_bar_height"
android:orientation="horizontal"
>
<EditText
android:id="@+id/chat_input_edittext"
android:layout_weight="7"
android:layout_width="0dp"
android:layout_height="match_parent"
android:inputType="textAutoCorrect"
/>
<Button
android:id="@+id/chat_send_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="@drawable/ic_action_send_now"
/>
</LinearLayout>
RecyclerView 是可见和可滚动的,但 LinearLayout 和里面的 Views 不可见......我尝试了很多东西,但到目前为止没有任何效果.
The RecyclerView is visible and scrollable but the LinearLayout and the Views inside are not visible... I tried quite a few things but nothing has worked so far.
你们中的任何人都可以指出我正确的方向吗?
Can any of you please point me into the right direction?
非常感谢!
推荐答案
将根视图更改为 FrameLayout.将 LinearLayout 的重力设置为底部
Change the root view to a FrameLayout. Set the gravity of the LinearLayout to bottom
<FrameLayout 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.support.v7.widget.RecyclerView
android:id="@+id/chat_listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingRight="@dimen/abc_action_bar_default_padding_material"
android:paddingLeft="@dimen/abc_action_bar_default_padding_material"
/>
<LinearLayout
android:layout_below="@id/chat_listview"
android:layout_width="match_parent"
android:layout_height="@dimen/bottom_bar_height"
android:layout_gravity="bottom"
android:orientation="horizontal">
<EditText
android:id="@+id/chat_input_edittext"
android:layout_weight="7"
android:layout_width="0dp"
android:layout_height="match_parent"
android:inputType="textAutoCorrect"/>
<Button
android:id="@+id/chat_send_button"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="@drawable/ic_action_send_now"/>
</LinearLayout>
</FrameLayout>
或者,您可以将线性布局包装在 FrameLayout 中并将其设置为 align_parentBottom = true 如果它是根目录下的相对布局或线性布局,并且您的视图中有其他内容.
Alternatively, you can wrap the linear layout in a FrameLayout and set it to align_parentBottom = true if it is a relative layout or a linear layout at your root and you have other things in your view.
