我是 android phonegap 应用程序的新手。我在android中尝试了一个phonegap应用程序，在这里我创建了一个数据库和表并使用javascript插入值，它工作正常，现在我想在android native中检索数据库值。这是我的代码

my javascript code:

function loaddb()
{
var db = openDatabase(‘testdb’, ’1.0′, ‘my database’, 2 * 1024 * 1024);

db.transaction(function (tx)
{
tx.executeSql(‘CREATE TABLE IF NOT EXISTS person (_id INTEGER, person_name TEXT, address TEXT)’);

tx.executeSql(‘INSERT INTO person (_id, person_name, address) VALUES(1, “Hardik Trivedi”, “Ahmedabad,Gujarat,India”)’);
tx.executeSql(‘INSERT INTO person (_id, person_name, address) VALUES(2, “Sonam Kapoor”, “Mumbai,Maharashtra,India”)’);
tx.executeSql(‘INSERT INTO person (_id, person_name, address) VALUES(3, “Rajnikanth”, “There is no specific address of him :) “)’);

});
}


my html code:


<html>
<head>
<script src=”db.js”&gt;</script>
<script src=”jquery.js”&gt;</script>

</head>
<body>
<div>
<script language=”javascript”&gt;
$(document).ready(function() {
alert(“Hello”);
loaddb();
});
</script>
</div>
<h4>Hello Friends !!!!!!</h4>
</body >

</html>

有没有可能在 android 中检索这个 javascript 数据库？
