アンドロイドでSQL Serverからテーブルローをフェッチしていますが、プログレスバーに表示したいのですが問題があります。テーブル行の長さを取ることを許さない..my接続クラス。SQL Serverからアンドロイドでテーブル行をダウンロード中に進行状況バーを表示
String ip="192.168.43.85";
String classs="net.sourceforge.jtds.jdbc.Driver";
String db="mydatabasename";
String uname="myname";
String pass="pass";
@SuppressLint("New Api")
public Connection CON() throws IOException{
StrictMode.ThreadPolicy policy=new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Connection connection=null;
String ConUrl=null;
try {
Class.forName(classs);
ConUrl="jdbc:jtds:sqlserver://"+ip+";"
+ "databaseName="+db+";user="+uname+";password="
+pass+";";
connection= DriverManager.getConnection(ConUrl);
} catch (ClassNotFoundException e) {
Log.e("ERRO",e.getMessage());
} catch (SQLException e) {
Log.e("ERROR",e.getMessage());
} catch (Exception e) {
Log.e("ERROr", e.getMessage());
}
return connection;
}
私はGoogleからのいくつかの例を試してみましたが、すべての例は、HTTPおよびURLを使用していますが、私は長さを見つけるために、URLを持っていません。
Connection conn = null;
