以编程方式更改小部件的渐变背景 [英] Programmatically Change Gradient Background of Widget

问题描述

我要完成的工作:

int[] colors = new int[]{colorDark,colorLight}
GradientDrawable gd = new GradientDrawable(TOP_BOTTOM, colors);
remoteView.setBackgroundDrawable(gd); //method does not exist

显然这是不可能的.

我该怎么做?(如果可能的话)

我不想在xml文件中为不同的颜色创建多个形状，因为这会限制选项.

I do not want to have to create multiple shapes in xml files for different colors, because this limits options.

我尝试将可绘制对象转换为位图并调用setImageViewBitmap.我使用此代码进行了转换，并使用了此代码以获取宽度/高度，但是我无法填充小部件(此外，设备的显示宽度/高度确实不是我所需要的)

I have tried converting my drawable to a bitmap and calling setImageViewBitmap. I converted with this code and used this code to get the width/height, but I'm unable to get the widget to be filled (additionally, the device's display width/height really aren't what I need anyway)

推荐答案

我只是在猜测.您可以尝试扩展RemoteViews并覆盖apply函数吗?

I am just guessing. Can you try to extend RemoteViews and override the apply function:

public class MySpecialRemoteViews extends RemoteViews {

    //add the Constructors

    public View apply(Context context, ViewGroup parent) {
        View result = super.apply(context, parent);

        //your code
        int[] colors = new int[]{colorDark,colorLight}
        GradientDrawable gd = new GradientDrawable(TOP_BOTTOM, colors);
        result.setBackgroundDrawable(gd);
        //end of your code

        return result;
    }
}
