Android Activity.recreate() 更改字体大小引起Fragment的混乱 10C

有时候fragment会直接卡死不动 有时候会就只显示两个fragment...

2个回答

可以试试在recreat()方法里先remove掉fragment,再进行字体大小的更改

Acivity重新创建会触发activity的异常销毁,从而走activity的异常销毁的生命周期,即在destroy之前会调用onSaveInstanceState方法去保存视图数据,之后页面创建时会调用onRestoreInstanceState方法获取之前存储的数据并进行还原.楼主可以考虑将需要保存的数据通过此方法进行数据还原,和fragment的重新绑定.
分析楼主的原因可能是,fragment内有依赖父activity的方法,而activity销毁重建的过程中会导致找不到父元素,而显示重复或数目错误可能是由于销毁过程的fragment解绑和重复添加,可以在绑定fragment的过程中添加tag进行识别,在activity重新创建的过程中去重新加载fragment,通过tag去判断fragment是否已经添加

Android中点击back键后当前活动无法销毁
正在学习做一个夜间模式的功能,出现了一个问题。遇到过的可以指教一下,先谢谢。启动app后启动活动A,然后通过一个button启动活动B(设置界面),在B界面切换夜间模式后,back键返回A活动,这时候回调了onActivityResult()方法。 在这个方法里,我调用了recreate(),也实现了夜间模式切换,但是此时我再按back键退出程序的时候一直退出不了同时打印以下三行日志,如下: ![图片说明](https://img-ask.csdn.net/upload/201603/08/1457442196_104690.png)
navicat 维护计划里面的优化表具体完成的是什么
从别人那导入的一个数据库,一张表里面的数据70w条左右,但是执行select * 需要6秒以上,新建了一个数据库,单独将这张表导出来,结果执行速度就在1秒左右。原来的数据库还是需要6秒的时间,今天找原因的时候在navicat上面在这张表上右击点维护,优化表,优化完成之后速度也变为0.8s左右了,优化结果里面说这张表并不支持优化(Table does not support optimize, doing recreate + analyze instead)想问一下,这个优化表具体完成的什么功能,速度提升的这么多???
创建数据库后oncreate方法没被调用
我使用helper创建一个新数据库。按照文档所说的,当数据库一创建,oncreate方法就会被调用,但是这个方法没有被准确的调用。 下面是我要实现的代码。 OpenHelper(Context context) { super(context, "examplee.db", null, 1 ); SQLiteDatabase sqlite = null; Log.w(TAG, "Openhelp database, "); sqlite = context.openOrCreateDatabase("examplee.db", Context.MODE_PRIVATE, null ); Log.e ( TAG,"SQ lite database object "+sqlite ); } public void onOpen(SQLiteDatabase db) { Log.e ( TAG,"On open called "); } @Override public void onCreate(SQLiteDatabase db) { Log.w(TAG, " On create "); //db.execSQL(sql); //db.execSQL("CREATE TABLE " + TABLE_NAME + "(id INTEGER PRIMARY KEY, name TEXT)"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { Log.w(TAG, "Upgrading database, this will drop tables and recreate."); //db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME); //onCreate(db); } 1.除了使用helper,还有别的方法能创建数据库吗? 2.在数据库创建中,什么样的回调函数会被调用然后再被销毁?

Killer Names
Problem Description > Galen Marek, codenamed Starkiller, was a male Human apprentice of the Sith Lord Darth Vader. A powerful Force-user who lived during the era of the Galactic Empire, Marek originated from the Wookiee home planet of Kashyyyk as the sole offspring of two Jedi Knights—Mallie and Kento Marek—who deserted the Jedi Order during the Clone Wars. Following the death of his mother, the young Marek's father was killed in battle by Darth Vader. Though only a child, Marek possessed an exceptionally strong connection to the Force that the Dark Lord of the Sith sought to exploit. > > When Marek died in 2 BBY, shortly after the formation of the Alliance, Vader endeavored to recreate his disciple by utilizing the cloning technologies of the planet Kamino. The accelerated cloning process—an enhanced version of the Kaminoan method which allowed for a rapid growth rate within its subjects—was initially imperfect and many clones were too unstable to take Marek's place as the Dark Lord's new apprentice. After months of failure, one particular clone impressed Vader enough for him to hope that this version might become the first success. But as with the others, he inherited Marek's power and skills at the cost of receiving his emotions as well, a side effect of memory flashes used in the training process. > > — Wookieepedia Darth Vader is finally able to stably clone the most powerful soilder in the galaxy: the Starkiller. It is the time of the final strike to destroy the Jedi remnants hidden in every corner of the galaxy. However, as the clone army is growing, giving them names becomes a trouble. A clone of Starkiller will be given a two-word name, a first name and a last name. Both the first name and the last name have exactly n characters, while each character is chosen from an alphabet of size m. It appears that there are m2n possible names to be used. Though the clone process succeeded, the moods of Starkiller clones seem not quite stable. Once an unsatisfactory name is given, a clone will become unstable and will try to fight against his own master. A name is safe if and only if no character appears in both the first name and the last name. Since no two clones can share a name, Darth Vader would like to know the maximum number of clones he is able to create. Input The First line of the input contains an integer T (T≤10), denoting the number of test cases. Each test case contains two integers n and m (1≤n,m≤2000).

问题要求如下: 输入格式: 输入第一行是一个正整数 N (1 <= N <= 100000),表示一共有 N 个用户名。接下来有 N 行,每一行是一个用户名,长度不超过 100,均由大写字母和小写字母组成。 输出格式: 请按照输入顺序输出,如果用户名在前面出现过则输出“Yes”,否则输出“No”,一行输出一个。 我的解答如下,并不能被系统AC,求问为什么。。。测试数据能过 #include<iostream> #include<string> #include <stdlib.h> using namespace std; class HashTable { private: int size; string* elem; public: HashTable() { size=200000; elem=new string[size]; for(int i=0;i<size;i++) { elem[i]="#"; } } ~HashTable() { delete[] elem; } int hash(string& index) { int code=0; for(size_t i=0;i<index.length();i++) { if(isupper(index[i])) index[i]=index[i] - 'A' + 'a'; } for(size_t i=0;i<index.length();i++) { code=(code*256+index[i]+128)%size; } return code; } bool search(string& index, int& pos, int& times) { pos=hash(index); times=0; while(elem[pos]!="#" && elem[pos]!=index) { times++; if(times<size) { pos=(pos+1)%size; } else { return false; } } if(elem[pos]==index) { return true; } else { return false; } } int insert(string& index) { int pos,times; if(search(index,pos,times)) { return 2; } else if(times<size/2) { elem[pos]=index; return 1; } else { recreate(); return 0; } } void recreate() { string* temp_elem; temp_elem=new string[size]; int copy_size=size; for(int i=0;i<size;i++) { temp_elem[i]=elem[i]; } delete[] elem; size=size*2; elem=new string[size]; for(int i=0;i<size;i++) { elem[i]="#"; } for(int i=0;i<copy_size;i++) { if(temp_elem[i]!="#") { insert(temp_elem[i]); } } delete[] temp_elem; } }; int main() { HashTable hashtable; int n, temp_pos, temp_times; cin>>n; string buffer; cin>>buffer; hashtable.insert(buffer); cout<<"NO"<<endl; for(int i=0;i<n-1;i++) { cin>>buffer; if(hashtable.search(buffer,temp_pos,temp_times)) { cout<<"YES"<<endl; } else { cout<<"NO"<<endl; } hashtable.insert(buffer); } return 0; }
用C语言解决MOD 109+7的最大值的一个算法问题
Problem Description > Galen Marek, codenamed Starkiller, was a male Human apprentice of the Sith Lord Darth Vader. A powerful Force-user who lived during the era of the Galactic Empire, Marek originated from the Wookiee home planet of Kashyyyk as the sole offspring of two Jedi Knights—Mallie and Kento Marek—who deserted the Jedi Order during the Clone Wars. Following the death of his mother, the young Marek's father was killed in battle by Darth Vader. Though only a child, Marek possessed an exceptionally strong connection to the Force that the Dark Lord of the Sith sought to exploit. > > When Marek died in 2 BBY, shortly after the formation of the Alliance, Vader endeavored to recreate his disciple by utilizing the cloning technologies of the planet Kamino. The accelerated cloning process—an enhanced version of the Kaminoan method which allowed for a rapid growth rate within its subjects—was initially imperfect and many clones were too unstable to take Marek's place as the Dark Lord's new apprentice. After months of failure, one particular clone impressed Vader enough for him to hope that this version might become the first success. But as with the others, he inherited Marek's power and skills at the cost of receiving his emotions as well, a side effect of memory flashes used in the training process. > > — Wookieepedia Darth Vader is finally able to stably clone the most powerful soilder in the galaxy: the Starkiller. It is the time of the final strike to destroy the Jedi remnants hidden in every corner of the galaxy. However, as the clone army is growing, giving them names becomes a trouble. A clone of Starkiller will be given a two-word name, a first name and a last name. Both the first name and the last name have exactly n characters, while each character is chosen from an alphabet of size m. It appears that there are m2n possible names to be used. Though the clone process succeeded, the moods of Starkiller clones seem not quite stable. Once an unsatisfactory name is given, a clone will become unstable and will try to fight against his own master. A name is safe if and only if no character appears in both the first name and the last name. Since no two clones can share a name, Darth Vader would like to know the maximum number of clones he is able to create. Input The First line of the input contains an integer T (T≤10), denoting the number of test cases. Each test case contains two integers n and m (1≤n,m≤2000). Output For each test case, output one line containing the maximum number of clones Vader can create. Output the answer mod 109+7 Sample Input 2 3 2 2 3 Sample Output 2 18
