Android: Cannot make a static reference to the non-static method getResources() from the type View
提问by rAge
I've got problem with my simple apliccation.
I don't want paste tons of code.
I've got class Zaladujwhere i must load files using getResources().
我的简单应用程序有问题。我不想粘贴大量代码。我有课程Zaladuj，我必须使用getResources().
loading_screen = BitmapFactory.decodeResource(Widok.getResources(),R.drawable.loading_screen);
On this line i've got error:
在这一行我有错误：
Cannot make a static reference to the non-static method getResources() from the type View.
无法从类型 View 对非静态方法 getResources() 进行静态引用。
I put all classes codes here: http://www.pcyra.pl/badpanda
It's not a website, it's just folder with my project. I create instance of View in MainActivity, The error shows in class Zaladujon line 50.
我把所有的课程代码放在这里：http: //www.pcyra.pl/badpanda
这不是一个网站，它只是我的项目的文件夹。我在 MainActivity 中创建了 View 的实例，错误显示在Zaladuj第 50 行的类中。

getResources()is not a static method. You need an instance of the View(or Widokin your case) to call it. Your best bet would be to add a parameter to your Zaladujclass that accepts a Contextthen use getResources()on that:
getResources()不是静态方法。您需要一个View（或Widok在您的情况下）的实例来调用它。您最好的选择是向您的Zaladuj类添加一个参数，该参数接受Context然后使用getResources()：
private Context context;
public Zaladuj(Context con)
{
super()
this.context = con
}
private void downloadResources()
{
//
loading_screen = BitmapFactory.decodeResource(this.context.getResources(),R.drawable.loading_screen);
//
int count = 10;
for (int i = 0; i < count; i++)
{
try { Thread.sleep(1000); } catch (InterruptedException ignore) {}
}
}

Since the getResources()method isn't static, you will need to create an instance of your Widokclass to be able to call it, eg:
由于该getResources()方法不是static，您将需要创建您的Widok类的一个实例才能调用它，例如：
Widok widok = new Widok(context);
BitmapFactory.decodeResource(widok.getResources(),R.drawable.loading_screen);

The error is clearly telling you whats wrong.You are not allowed to call it with Widok.
错误清楚地告诉你出了什么问题。你不能用 Widok 调用它。
If you are in activity class then call
如果你在活动课然后打电话
BitmapFactory.decodeResource(getResources(),R.drawable.loading_screen);
If you are in non-activity class then you will need Activity context.
如果您在非活动类中，那么您将需要活动上下文。
Like if you are in AsyncTask then you would write something like this
就像如果你在 AsyncTask 那么你会写这样的东西
BitmapFactory.decodeResource(context.getResources(),R.drawable.loading_screen);
Just make sure you pass correct activity context in constructor.
只要确保在构造函数中传递正确的活动上下文。

The reason you're getting that error "Cannot make a static reference to the non-static method getResources() from the type View." is because the getResources() method is not a static method. In other words, you'll need to isntantiate a new Widok
您收到该错误的原因是“无法从类型视图对非静态方法 getResources() 进行静态引用。” 是因为 getResources() 方法不是静态方法。换句话说，您需要创建一个新的 Widok
Widok w = new Widok(context);
asnd then call the resources on that object
然后调用该对象上的资源
w.getResource();
**Edit
**编辑
This is the code you'd put in your activity class. You pass the keyword "this" to the constructor of Widok which references the application context
这是您放在活动类中的代码。您将关键字“this”传递给引用应用程序上下文的 Widok 的构造函数
Widok w = new Widok(this);
loading_screen = BitmapFactory.decodeResource(w.getResources(),R.drawable.loading_screen);
