来自没有扩展活动的调用的getstring（）(getstring() from a call without extend activity)

来自没有扩展活动的调用的getstring（）(getstring() from a call without extend activity)

我有一个简单类的问题，其中包含我想从另一个类调用的信息。 例如，这里是包含信息的类Util ：

public class Util{ public ArrayList<RecetaBean> getRellenas() { ArrayList<RecetaBean> MiLista = new ArrayList<RecetaBean>(); RecetaBean receta1 = new RecetaBean(); String ingrediente1[] = { getString(R.string.app_name),getString(R.string.app_name), }; receta1.setIngredientesLista(ingrediente1); MiLista.add(receta1); MiLista.add(receta1); MiLista.add(receta1); return MiLista; } }

然后在另一个类中我得到像这样调用的Items：

Util u = new Util(); ArrayList<RecetaBean> Recetas = u.getRellenas();

所以，我在使用GETSTRING的类Util中GETSTRING了执行问题，因为我想得到一个不同的字符串（因为语言不同）。 退出错误的方法是从Activity扩展类Util ，但Util不是Activity ！ 如果我从Activity扩展，应用程序崩溃。

I have a problem with a simple class that contains information that I will like to call from another class. For example here is the class Util which contains the info:

public class Util{ public ArrayList<RecetaBean> getRellenas() { ArrayList<RecetaBean> MiLista = new ArrayList<RecetaBean>(); RecetaBean receta1 = new RecetaBean(); String ingrediente1[] = { getString(R.string.app_name),getString(R.string.app_name), }; receta1.setIngredientesLista(ingrediente1); MiLista.add(receta1); MiLista.add(receta1); MiLista.add(receta1); return MiLista; } }

Then in another class I get the Items calling like this:

Util u = new Util(); ArrayList<RecetaBean> Recetas = u.getRellenas();

So, I have a execution problem in the class Util with the GETSTRING, because I would like to get a different string (because of different languages). The way to quit the error is to extend the class Util from Activity, but Util is not an Activity! And if I extend from Activity, the app crash.

您需要做的就是在方法中定义一个上下文。

并称之为这样;

Util u = new Util(); ArrayList<RecetaBean> Recetas = u.getRellenas(this);

和你在你的上下文这样的方法：

public ArrayList<RecetaBean> getRellenas(Context con) { ArrayList<RecetaBean> MiLista = new ArrayList<RecetaBean>(); RecetaBean receta1 = new RecetaBean(); String ingrediente1[] = { con.getString(R.string.app_name), con.getString(R.string.app_name), }; receta1.setIngredientesLista(ingrediente1); MiLista.add(receta1); MiLista.add(receta1); MiLista.add(receta1); return MiLista; }

all you need to do is Define a Context in the Method .

and call it like this;

Util u = new Util(); ArrayList<RecetaBean> Recetas = u.getRellenas(this);

and you the context in you Methods like this:

public ArrayList<RecetaBean> getRellenas(Context con) { ArrayList<RecetaBean> MiLista = new ArrayList<RecetaBean>(); RecetaBean receta1 = new RecetaBean(); String ingrediente1[] = { con.getString(R.string.app_name), con.getString(R.string.app_name), }; receta1.setIngredientesLista(ingrediente1); MiLista.add(receta1); MiLista.add(receta1); MiLista.add(receta1); return MiLista; }
