我有一个情况我需要在LinearLayout中设置背景编程。
在我的布局,我设置我的背景使用`机器人:背景=机器人:ATTR / activatedBackgroundIndicator,但我想设置这个编程:
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:ID =@ + ID / myLayoutId
机器人:layout_width =WRAP_CONTENT
机器人:layout_height =FILL_PARENT
机器人:重力=左|中心
机器人:paddingBottom会=5dip
机器人:以下属性来=5dip
机器人:背景=机器人:ATTR / activatedBackgroundIndicator
机器人:paddingTop =5dip>
我使用的尝试:
绘制对象D = getActivity()getResources()getDrawable(android.R.attr.activatedBackgroundIndicator)。
rootLayout.setBackgroundDrawable(四);
但它崩溃。任何想法?
编辑:我一直在使用也尝试过:
rootLayout.setBackgroundResource(android.R.attr.activatedBackgroundIndicator);

我有同样的问题,我固定它使用这块code。
在android.R.attr。*是指向了一个主题,而不是定义的实际绘制资源。你必须使用 TypedArray 的访问ID。
theView = this.inflater.inflate(R.layout.list_row_job_favorited,NULL);
如果(android.os.Build.VERSION.SDK_INT> = android.os.Build.VERSION_ codeS.HONEYCOMB){
TypedArray A = mContext.obtainStyledAttributes(新INT [] {android.R.attr.activatedBackgroundIndicator});
INT资源= a.getResourceId(0,0);
//第一个0是该指数在数组中,第二个是默认值
a.recycle();
theView.setBackground(mContext.getResources()getDrawable(资源)。);
}
我曾经在我的自定义列表适配器时检测SDK上正常工作。
I have a situation where I need to set a background on a LinearLayout programatically.
In my layout, I am setting my background using `android:background="?android:attr/activatedBackgroundIndicator", but I want to set this programatically:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/myLayoutId"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="left|center"
android:paddingBottom="5dip"
android:paddingLeft="5dip"
android:background="?android:attr/activatedBackgroundIndicator"
android:paddingTop="5dip" >
I've tried using:
Drawable d = getActivity().getResources().getDrawable(android.R.attr.activatedBackgroundIndicator);
rootLayout.setBackgroundDrawable(d);
But it crashes. Any ideas?
Edit: I had also tried using:
rootLayout.setBackgroundResource(android.R.attr.activatedBackgroundIndicator);

解决方案
I had the same problem and I fixed it using this piece of code.
The android.R.attr.* are pointers to the in a theme and not to the actual drawable resource defined. You have to use the TypedArray to access the id.
theView = this.inflater.inflate(R.layout.list_row_job_favorited, null);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
TypedArray a = mContext.obtainStyledAttributes(new int[] { android.R.attr.activatedBackgroundIndicator });
int resource = a.getResourceId(0, 0);
//first 0 is the index in the array, second is the default value
a.recycle();
theView.setBackground(mContext.getResources().getDrawable(resource));
}
I used this in my custom list adapter when detects SDK upper and worked fine.
