通过BaseApplication传值

一、BaseApplication：

public class BaseApplication extends Application{
private static final String tag="BaseApplication";
private static BaseApplication mInstance;
public List<String> pathlist = new ArrayList<String>();


@Override
public void onCreate() {
LogUtil.i(tag, "----------onCreate:");
super.onCreate();
mInstance = this;
//initCrashHandle();
}

//当程序发生Uncaught异常的时候,由该类来接管程序,一定要在这里初始化
private void initCrashHandle() {
MyCrashHandler.getInstance().init(this);
}


public static BaseApplication getInstance() {
return mInstance;
}

//内存不足，杀死自己  
//是谁杀了我，而我又杀了谁！！！    
//是我，杀了我？  
//回答正确，动手吧！
@Override
public void onLowMemory() {
android.os.Process.killProcess(android.os.Process.myPid());
super.onLowMemory();
}
}

二、放值进BaseApplication：

        private ArrayList<ImageItem> dataList;

        BaseApplication application = BaseApplication.getInstance();
        application.dataList = dataList;

三、从BaseApplication中取值：

        private ArrayList<ImageItem> dataList;

        BaseApplication application = BaseApplication.getInstance();
dataList = application.dataList;
