1. 通过 MySQL在windows下的配置 中介绍第二种方法,在服务器机器上配置php和mysql环境,譬如我的服务器机器ip为:10.141.249.1362. 新建在test数据库下新建一个teacher表,表的内容如下:
3. 在服务器机器上的phpnow安装目录E:\PHPnow-1.5.5\htdocs下新建一个test.php文件,文件内容如下:
$link=mysql_connect("127.0.0.1","root","123456");
mysql_query("SET NAMES utf8");
mysql_select_db("test",$link);
$sql=mysql_query("select * from teacher ",$link);
while($row=mysql_fetch_assoc($sql))
$output[]=$row;
print(json_encode($output));
mysql_close();
?>
4. 新建一个Android Java Project
需要修改的是一下三个文件:AndroidTestActivity.java、main.xml、AndroidManifest.xml
//AndroidTestActivity.java
package
com.knight.android.test;//根据实际的工程需要,修改包的名称
import
java.io.BufferedReader;
import
java.io.InputStream;
import
java.io.InputStreamReader;
import
java.util.ArrayList;
import
org.apache.http.HttpEntity;
import
org.apache.http.HttpResponse;
import
org.apache.http.NameValuePair;
import
org.apache.http.client.HttpClient;
import
org.apache.http.client.methods.HttpGet;
import
org.apache.http.impl.client.DefaultHttpClient;
import
org.json.JSONArray;
import
org.json.JSONException;
import
org.json.JSONObject;
import
android.app.Activity;
import
android.net.ParseException;
import
android.os.Bundle;
import
android.util.Log;
import
android.view.View;
import
android.widget.Button;
import
android.widget.EditText;
public
class
AndroidTestActivity
extends
Activity {
JSONArray jArray;
String result
= null;
InputStream is
= null;
StringBuilder sb
= null;
@Override
public
void
onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b1 = (Button) findViewById(R.id.button1);
b1.setOnClickListener(new
Button.OnClickListener()
{
@Override
public
void
onClick(View v)
{
//
TODO
Auto-generated
method stub
EditText tv = (EditText) findViewById(R.id.editView);
ArrayList
//
http get
try
{
HttpClient httpclient = new
DefaultHttpClient();
HttpGet httpget = new
HttpGet(
"http://10.141.249.136/test.php");
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
is
=
entity.getContent();
} catch
(Exception e)
{
Log.e("log_tag", "Error
in http connection" + e.toString());
}
//
convert response to string
try
{
BufferedReader reader = new
BufferedReader(
new
InputStreamReader(is, "iso-8859-1"), 8);
sb
= new
StringBuilder();
sb.append(reader.readLine()
+ "\n");
String line = "0";
while
((line =
reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result
= sb.toString();
} catch
(Exception e)
{
Log.e("log_tag", "Error
converting result " + e.toString());
}
//
paring data
int
ct_id;
String ct_name;
try
{
jArray
= new
JSONArray(result);
JSONObject json_data = null;
for
(int
i = 0; i <
jArray.length(); i++) {
json_data = jArray.getJSONObject(i);
ct_id = json_data.getInt("id");
ct_name = json_data.getString("name");
tv.append(ct_name + "
\n");
}
} catch
(JSONException e1)
{
//
Toast.makeText(getBaseContext(), "No City Found"
//
,Toast.LENGTH_LONG).show();
} catch
(ParseException e1)
{
e1.printStackTrace();
}
}
});
}
}
layout/main.xml
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
额额 我这里有 安卓连接mysql的例子,你看需要吗?
