Android Activity has leaked IntentReceiver that was originally registered here. Are you missing a call to unregisterReceiver()?

參考網址:http://stackoverflow.com/questions/14357566/activity-has-leaked-intentreceiver-that-was-originally-registered-here-are-you

@Override
protected void onPause() {
    super.onPause();

    unregisterReceiver(yourReceiver);
}

Android不讓弹出鍵盤擋住View

在AndroidManifest.xml 加adjustPan
 <activity
....
....
.
 android:windowSoftInputMode="adjustPan"

</activity>

OpenLDAP for windows(連接mysql)

openldap 版本:openldap-2.4.38-x86

下載網址http://sourceforge.net/projects/openldapwindows/

安裝步驟 一直下一步就好(安裝路徑我是設在C:\OpenLDAP)

安裝完後打開 C:\OpenLDAP\etc\openldap\slapd.conf

找到BDB database definitions部分

可以修改下面3行(我是用默認的,做測試用的而已)         

suffix "dc=my-domain,dc=com"

rootdn "cn=Manager,dc=my-domain,dc=com"

rootpw test

過來就是連接mysql部分

找到# MySQL Database  修改資料庫資料

backend              sql

database             sql

suffix               "dc=example,dc=com"

rootdn               "cn=root,dc=example,dc=com"

rootpw               test

dbname               openldap    #資料庫表名稱

dbuser               root         #資料庫帳號

dbpasswd           ******     #資料庫密碼

insentry_stmt       "INSERT INTO ldap_entries (dn,oc_map_id,parent,keyval) VALUES (?,?,?,?)"

subtree_cond         "ldap_entries.dn LIKE CONCAT('%',?)"

upper_func           "upper"

concat_pattern       "?+?"

has_ldapinfo_dn_ru   no

check_schema         yes

database        monitor

修改完到C:\OpenLDAP\etc 打開odbc.ini

找到MySQLTestServer 改成

[openldap]  #資料庫表名稱

Driver=MySQL

Description=Test MySQL Database 2013

Server=localhost

Port=3306

Database=openldap #資料庫表名稱

# UID=openldap

Password=*****  #資料庫密碼

改完後到C:\OpenLDAP\etc\back-sql\mysql  

把01_backsql_create.sql,

   02_testdb_create.sql

   03_testdb_data.sql

   04_testdb_metadata.sql

都匯到資料庫

設定完後到C:\OpenLDAP\libexec  按StartLDAP.cmd  啟動

啟動完就可以連了

Android update ViewPager View

@Override
public Object instantiateItem(ViewGroup container, int position) {
    View view = null;
    view = mInflater.inflate(R.layout.record_list_layout, null);          
    TextView test= (TextView) view.findViewById(R.id.test);
    String key = "test" + position;

    test.setTag(key);
  ((ViewPager) arg0).addView(view );
    return view;
}

//0為第一筆
TextView test= myViewPager.findViewWithTag("test0");
// 更新內容
if (test!= null ) {
    test.setText("update");
}

JAVA 亂數排序 Collections.shuffle

ArrayList<String> list=new ArrayList<String>();

list.add("a");

list.add("b");

list.add("c");

list.add("d");

Collections.shuffle(list);

for(String result:list)

{

System.out.println(result);

}

android viewpager setting destroy

出處:http://stackoverflow.com/questions/8348707/prevent-viewpager-from-destroying-off-screen-views

in revision 4 of the Support Package, a method was added to ViewPager which allows you to specify the number of offscreen pages to use, rather than the default which is 1.

In your case, you want to specify 2, so that when you are on the third page, the first one is not destroyed, and vice-versa.

mViewPager = (ViewPager)findViewById(R.id.pager);
mViewPager.setOffscreenPageLimit(2);
