Android的：改变的LinearLayout中的一个小部件 [英] Android: Changing LinearLayout in a widget

问题描述

我有这个真的很恼人的问题：

在我的小工具，我想改变背景由code。我注意到了谷歌文档比我可以很容易地改变ImageView的背景：

  remoteViews.setImageViewResource（R.id.my_iv，R.drawable.my_bg）;
 

好了，太容易了，现在我想改变线性布局..我看了一下远程视窗ID，我可以改变一个位图，智力，布尔，字符串，等等...但不是绘制。所以我想我不能使用：

<$p$p><$c$c>remoteViews.setBitmap(R.id.my_ll,"setBackgroundDrawable",BitmapFactory.de$c$cResource(context.getResources(), R.drawablemy_bg））;

我完全disapointed，并试图在最后的想法：

  views.setInt（R.id.my_ll，setBackgroundResource，R.drawable.my_bg）;
 

但logcat的告诉我：

  

android.widget.RemoteViews $ ActionException：观点：   android.widget.LinearLayout不能使用   法RemoteViews：   setBackgroundResource（INT）

我完全失去了，我真的不知道该怎么办......

我真的AP preciate任何帮助。

感谢了很多！

解决方案

您不能修改背景的方式，由于 RemoteViews API的限制。

你可以做的就是选择不同的布局 - 一个与你想要的背景 - 当你创建了这个特定的更新您的 RemoteViews 实例

I have this really annoying problem:

In my widget, i would like to change the background by code. I noticed on the Google doc than I can easily change the background of an Imageview:

remoteViews.setImageViewResource(R.id.my_iv, R.drawable.my_bg);

Ok, too easy, i want to change now the Linear layout.. What I read about the remoteview id that I can change a Bitmap, Int, Bool, String, etc... but not a drawable. So i guess i cannot use:

remoteViews.setBitmap(R.id.my_ll,"setBackgroundDrawable",BitmapFactory.decodeResource(context.getResources(), R.drawablemy_bg));

I am totally disapointed and tried a last idea:

views.setInt(R.id.my_ll,"setBackgroundResource",R.drawable.my_bg);

But The logcat told me:

android.widget.RemoteViews$ActionException:view: android.widget.LinearLayout can't use method with RemoteViews: setBackgroundResource(int)

I am totally lost and I really don't know what to do...

I would really appreciate any help.

Thank a lot!

解决方案

You cannot modify the background that way, due to limitations in the RemoteViews API.

What you can do is choose a different layout -- one with the background you want -- when you create your RemoteViews instance for this particular update.
