合并视图的layout_weight和maxWidth [英] Combine layout_weight and maxWidth for views

问题描述

我想让我的布局更加景观友好，一个常见的模式是添加一个 LinearLayout 与一些按钮（例如确定|取消），只是设置 layout_weight 的值，以使空间均匀分布。问题是，当您在横向模式下使用手机或（特别是）平板电脑时，最终会出现看起来很可笑的巨大按钮。我尝试在按钮和线性布局上设置 maxWidth ，但没有效果。什么是最简单的方法来实现呢？即，设置视图的最大水平尺寸，使得其不会增长到整个宽度。我尝试了一堆不同的东西，但没有工作。

I'm trying to make my layouts more landscape friendly, and a common pattern I have is to add a LinearLayout with some buttons (e.g. OK | Cancel) and just set a value for layout_weight so that the space is evenly distributed. The problem is that when you use a phone or (especially) a tablet in landscape mode, you end up with humongous buttons that look ridiculous. I tried setting maxWidth on the buttons and on the linear layout but to no avail. What would be the easiest way to achieve this? Namely, setting a maximum horizontal size for the view so that it does not grow to the whole width. I tried a bunch of different things, but none worked.

这里是一个示例布局：

    <LinearLayout 
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:gravity="center_horizontal"
      android:paddingLeft="10dp"
      android:paddingRight="10dp"
      android:paddingTop="6dp"
      android:paddingBottom="6dp">
      <Button 
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:enabled="false"
        android:textStyle="bold"
        android:text="@string/button1" />
      <Button 
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="@string/button2" />
    </LinearLayout>

注意：我知道我可以创建一个新的布局文件，

Note: I know I can create a new layout file for landscape and do magic there. I want to keep the specialized layout files to a minimum, and I would hope this does not require them.

推荐答案

我不需要这些特殊的布局文件，在这里测试它，但我会使用RelativeLayout，如下：

I don't have Eclipse here to test it, but I would use a RelativeLayout instead, something like:

<RelativeLayout
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  >
  <View
    android:id="@+id/centerView"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    />
  <Button 
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toLeftOf="@id/centerView"
    android:enabled="false"
    android:textStyle="bold"
    android:text="@string/button1" 
    />
  <Button 
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@id/centerView"
    android:text="@string/button2" 
    />
</RelativeLayout>

正如我所说，我现在无法测试，但你可以解决这个问题。

As I said, I can't test it right now, but you can work around this idea.

在旁注中，除非你的布局很简单，我通常为风景创建单独的布局。这是一个更多的工作，但你可以优化的视图更好的那种方式。特别是，如果你打算支持更大的屏幕。

On a side note, unless your layout is very simple, I usually create separate layouts for landscape. It's a little more work, but you can optimize the views much better that way. Specially, if you plan to support larger screens.
