android的Java方法:layout_gravity [英] Java method for android:layout_gravity

问题描述

我想知道是否有办法从 Java 方法调用 android:layout_gravity 属性.我没有在 Android 文档中找到任何方法来做到这一点.这是我要实现的布局的图片:

I would like to know if is there a way to call android:layout_gravity property from a Java method. I didn't found any method in Android documentation to do it. This is the picture of the layout I want to implement:

我知道通过 XML 来做，如下:

I know to do it through XML, as following:

<FrameLayout
    xlmns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

      <Button
         android:layout_gravity="left|center_vertical"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="<" />


      <Button
         android:layout_gravity="right|center_vertical"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text=">" />
</FrameLayout>

但在我的情况下，我需要通过 Java 代码来完成，因为我将动态实现另一个布局视图.为了避免将 XML 布局与 Java 代码合并，我更愿意使用 Java 进行所有布局.

But in my situation, I need to do it through Java code, because I'll implement another layout views dynamically. To avoid merging XML layout with Java code, I would prefer make all layout using Java.

推荐答案

据我所知你正在寻找 this 它用于其他布局的 FrameLayout，请参阅相应的 LayoutParams 类.要在 XML 中设置重力，请使用以下内容:

Well as far as I understand you looking for this It is for FrameLayout for other layout see appropriate LayoutParams classes. For setting gravity like in your XML use something like:

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT,Gravity.LEFT | Gravity.CENTER_VERTICAL)

后跟 addView 和新构造的 LayoutParams
