android 使用application內全局context

首先，寫一個類繼承Appclication

import android.app.Application;
import android.content.Context;
import android.content.res.Resources;

public class MyApplication extends Application{
    private static MyApplication mcontext;
    @Override
    public void onCreate() {
        // TODO Auto-generated method stub
        super.onCreate();
        mcontext=this;
    }
    public static Context getAppContext(){
        return mcontext;
    }
    public static Resources getAppResources(){
        return getAppResources();
    }
}

然后在manifest文件中的application中添加

android:name=".MyApplication"

這樣，就能在整個application內使用MyApplication.getAppContext()來獲得context而不用到處傳遞了
