无法连接到本地主机使用Android手机调试
问题描述:
Im很难从我的本地主机检索数据。我使用xampp。我想要的是显示从本地主机到Android手机列表视图的数据。这是我在网上找到的关于localhost和android的基本代码。这里是片段:无法连接到本地主机使用Android手机调试
p
ublic class Database_demo extends ListActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String result = null;
InputStream is = null;
StringBuilder sb = null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
List<String> r = new ArrayList<String>();
try{
//http post
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/android_connect3/");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}
catch(Exception e){
Toast.makeText(getBaseContext(),e.toString() ,Toast.LENGTH_LONG).show();
}
//Convert response to string
try
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"UTF-8"));
sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
is.close();
result = sb.toString();
}
catch(Exception e)
{
Toast.makeText(getBaseContext(),e.toString() ,Toast.LENGTH_LONG).show();
}
//END Convert response to string
try{
JSONArray jArray = new JSONArray(result);
JSONObject json_data=null;
for(int i=0;i<jArray.length();i++)
{
json_data = jArray.getJSONObject(i);
r.add(json_data.getString("reg"));
}
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, r));
}
catch(JSONException e1){
Toast.makeText(getBaseContext(),e1.toString() ,Toast.LENGTH_LONG).show();
} catch (ParseException e1) {
Toast.makeText(getBaseContext(),e1.toString() ,Toast.LENGTH_LONG).show();
}
}
}
,这里是我的PHP文件:
<?php
mysql_connect('localhost','root','');
mysql_select_db('android_sql');
$sql = "select * from reg";
$query = mysql_query($sql);
while($row = mysql_fetch_assoc($query)){
$output[] = $row;
}
print (json_encode($output));
mysql_close();
?>
这是我的例外: http://pastebin.com/QZkfG0bp

我得到了它。这里是我如何做。
InputStream is;
String result;
StringBuilder sb;
@Override
public void onCreate(Bundle savedInstanceState) {
}
我宣布他们为全球和删除空值ASIGN他们
答
你必须检查该行
HttpPost httppost = new HttpPost("http://10.0.2.2/android_connect3/");
变化
HttpPost httppost = new HttpPost("http://10.0.2.2/android_connect3/your_php_file_name");

我已经做到这一点的价值。这是行不通的.. – thenewbie 2012-07-06 02:35:27
