我在Android的一个例子，我尝试运行。
有2种方式来做到这一点。

I have an example in android that I am trying to run. There were 2 ways to do it..

// Get a drawable 
ColorDrawble redDrawable = (ColorDrawable).getResources().getDrawable(R.drawable.red_rectangle);

推荐答案

您可以简单地使用可绘制这样的：

you can simply use a drawable like this :

// Get a drawable 
Drawable redDrawable = YourActivity.this.getResources().getDrawable(R.drawable.red_rectangle); 

//Set it as a background to a text view 
textView.setBackgroundDrawable(redDrawable);//i've changed setBackground with setBackgroundDrawable.

或者你可以直接使用：

or you can directly use :

textView.setBackgroundResources(R.drawable.red_rectangle);

注意：清洁，重新生成项目，并运行它来测试
并为可绘制，你不需要声明它的strings.xml，只需添加上的文件夹可绘制的绘制，并且它会工作

NOTE : clean and rebuild your project , and run it to test and for the drawable, you dont need to declare it in strings.xml , just add your drawable on the folder drawables , and it will work
