Android:以编程方式设置视图样式 [英] Android: set view style programmatically

问题描述

以下是XML:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    style="@style/LightStyle"
    android:layout_width="fill_parent"
    android:layout_height="55dip"
    android:clickable="true"
    android:orientation="horizontal" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal" />

</RelativeLayout>

如何通过编程方式设置style属性?

How to set style attribute programmatically?

推荐答案

从技术上讲，您可以通过编程方式应用样式，并且始终使用自定义视图:

Technically you can apply styles programmatically, with custom views anyway:

private MyRelativeLayout extends RelativeLayout {
  public MyRelativeLayout(Context context) {
     super(context, null, R.style.LightStyle);
  }
}

一个参数构造函数是您以编程方式实例化视图时使用的一个参数.

The one argument constructor is the one used when you instantiate views programmatically.

因此，将此构造函数链接到带有样式参数的super.

So chain this constructor to the super that takes a style parameter.

RelativeLayout someLayout = new MyRelativeLayout(new ContextThemeWrapper(this,R.style.RadioButton));

或者就像@Dori所简单指出的那样:

Or as @Dori pointed out simply:

RelativeLayout someLayout = new RelativeLayout(new ContextThemeWrapper(activity,R.style.LightStyle));
