android4.0中setting模块修改preferencecategory显示的背景宽度。

android4.0中setting模块preferencecategory显示的背景宽度没有左右对齐到屏幕宽度，而是对齐在listitem上，求救怎么修改其背景宽度。

android7.0如何增加一个时区，比如波兰-华沙 Europe/Warsaw

以下这种方法不起作用啊， # Nigeria # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Africa/Lagos 0:13:36 - LMT 1919 Sep 1:00 - WAT 这样可以看到，尼日利亚只有一个城市可以作为时区ID，这个ID就是Africa/Lagos。 2.修改packages/apps/Settings/res/xml-xx-rYY/timezones.xml 或packages/apps/Settings/res_ext/xml-xx-rYY/timezones.xml （xx-rYY表示不同的语言和区域）,添加下面的内容（notice:如果只在xml-en-rUS下加那只在设置为en_US时才会有该时区，需要在每种语言下都添加）： <!-- timezones.xml 用于在setting中增加一个时区设置项 --> <timezone id="Africa/Lagos">Lagos</timezone> ( Android M ) 时区ID的定义是放在/frameworks/base/packages/SettingsLib/res/xml/timezones.xml文件中的，在这里面添加时区需要从新编译frameworks. 3.修改framework/base/core/res/res/xml/time_zones_by_country.xml，添加下面的内容 <!--time_zones_by_country.xml 这个用于自动匹配时区时使用，通过country code找一个时区 --> <!-- Nigeria, 1:00 --> <timezone code="ng">Africa/Lagos</timezone> <!-- 这里的code="ri"表示国家代码，比如中国对应cn，美国对应us，不清楚可以维基百科查询ISO_3166-1--> 我编译进行了全编,make -j8

求Android9.0以太网静态IP设置功能的补丁

cannot cast 'android.support.v4.app.FragmentTransaction' to 'android.app.FragmentTransaction

网上的解决方法针对的都是把FragmentTransaction转化成V4包下的FragmentTransaction有问题 但是，我却遇到了相反的情况。 无法由V4包下的FragmentTransaction转化成app.FragmentTransaction 有没有高人来指点一下啊？？ 注：**extends android.support.v4.app.Fragment**这个千万不能改 ``` package com.example.myslidepage.Fragment; import android.app.FragmentManager; import android.app.FragmentTransaction; import android.content.Context; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v4.*; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; import com.example.myslidepage.R; /** * Created by lenovo on 4/30/2019. */ public class Fragment2 extends android.support.v4.app.Fragment implements View.OnClickListener { public Button btn_news,btn_contact,btn_message,btn_setting; public MyFragment f1,f2,f3,f4; @Nullable public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) { View view =inflater.inflate(R.layout.tab2,container,false); btn_news = view.findViewById(R.id.btn_news); btn_contact = view.findViewById(R.id.btn_contact); btn_message = view.findViewById(R.id.btn_message); btn_setting = view.findViewById(R.id.btn_setting); btn_news.setOnClickListener(this); btn_contact.setOnClickListener(this); btn_message.setOnClickListener(this); btn_setting.setOnClickListener(this); //第一次初始化首页默认显示第一个fragment initFragment1(); initFragment2(); initFragment3(); initFragment4(); return view; } @Override public void onClick(View v) { if(v==btn_news){ initFragment1(); } else if(v==btn_message){ initFragment2(); } else if(v==btn_contact){ initFragment3(); } else{ initFragment4(); } } private void initFragment1(){ android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); //开启事务，fragment的控制是由事务来实现的 FragmentTransaction transaction=(FragmentTransaction)fragmentManager.beginTransaction(); //第一种方式（add），初始化fragment并添加到事务中，如果为null就new一个 if(f1 == null){ f1 = new MyFragment("消息",R.drawable.message_selected); transaction.add(R.id.main_frame_layout, f1); } //隐藏所有fragment hideFragment(transaction); //显示需要显示的fragment transaction.show(f1); transaction.commit(); } private void initFragment2(){ android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); FragmentTransaction transaction=(FragmentTransaction)fragmentManager.beginTransaction(); if(f2 == null){ f2 = new MyFragment("消息",R.drawable.message_selected); transaction.add(R.id.main_frame_layout, f2); } //隐藏所有fragment hideFragment(transaction); //显示需要显示的fragment transaction.show(f2); transaction.commit(); } private void initFragment3(){ android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); FragmentTransaction transaction=(FragmentTransaction)fragmentManager.beginTransaction(); if(f3 == null){ f3 = new MyFragment("消息",R.drawable.message_selected); transaction.add(R.id.main_frame_layout, f3); } //隐藏所有fragment hideFragment(transaction); //显示需要显示的fragment transaction.show(f3); transaction.commit(); } private void initFragment4(){ android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager(); FragmentTransaction transaction=(FragmentTransaction)fragmentManager.beginTransaction(); if(f4 == null){ f4 = new MyFragment("消息",R.drawable.message_selected); transaction.add(R.id.main_frame_layout, f4); } //隐藏所有fragment hideFragment(transaction); //显示需要显示的fragment transaction.show(f4); transaction.commit(); } //这个方法其实很巧，这个hide方法看一眼就是唬人的。这个方法将所有的fragment都hide了，因为他的判断条件是if(f1 != null) //因为一开始初始化的时候，f1f2f3都已经初始化一遍了，所以不可能都为空，既然都不为空，那就都隐藏。然后点击哪个方法，那个再显示。 private void hideFragment(FragmentTransaction transaction) { if(f1 != null){ transaction.hide(f1); } if(f2 != null){ transaction.hide(f2); } if(f3 != null){ transaction.hide(f3); } if(f4 != null){ transaction.hide(f4); } } } ```

怎么解决Activity name cannot be empty.

字节跳动视频编解码面经

引言 本文主要是记录一下面试字节跳动的经历。 三四月份投了字节跳动的实习（图形图像岗位），然后hr打电话过来问了一下会不会opengl，c++，shador，当时只会一点c++，其他两个都不会，也就直接被拒了。 七月初内推了字节跳动的提前批，因为内推没有具体的岗位，hr又打电话问要不要考虑一下图形图像岗，我说实习投过这个岗位不合适，不会opengl和shador，然后hr就说秋招更看重基础。我当时

开源一个功能完整的SpringBoot项目框架

福利来了，给大家带来一个福利。 最近想了解一下有关Spring Boot的开源项目，看了很多开源的框架，大多是一些demo或者是一个未成形的项目，基本功能都不完整，尤其是用户权限和菜单方面几乎没有完整的。 想到我之前做的框架，里面通用模块有：用户模块，权限模块，菜单模块，功能模块也齐全了，每一个功能都是完整的。 打算把这个框架分享出来，供大家使用和学习。 为什么用框架？ 框架可以学习整体

Java学习的正确打开方式

在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。 何谓学习？博主所理解的学习，它

程序员必须掌握的核心算法有哪些？

由于我之前一直强调数据结构以及算法学习的重要性，所以就有一些读者经常问我，数据结构与算法应该要学习到哪个程度呢？，说实话，这个问题我不知道要怎么回答你，主要取决于你想学习到哪些程度，不过针对这个问题，我稍微总结一下我学过的算法知识点，以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的，并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构，当然，我也会整理一些看过

程序员接私活怎样防止做完了不给钱？

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。 那么，怎么保证自己的薪酬安全呢？ 我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
