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);

}
