Java 如何在Android中使用Post方法发布任何数据

请告诉我代码的位置。

我正在创建一个应用程序

获取位置

获取位置并单击“发布”按钮后

很快，使用POST（HTTP）方法将其发送到我的PHP页面

如下面的应用程序屏幕截图所示，您可以看到两个输入框，其中包含LAT、LONG和Name值：

我有以下代码来获取位置：

public class MainActivity extends Activity implements LocationListener {
EditText lat;
EditText lng;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    /********** get Gps location service LocationManager object ***********/

    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

            /* CAL METHOD requestLocationUpdates */

    // Parameters :
    //   First(provider)    :  the name of the provider with which to register
    //   Second(minTime)    :  the minimum time interval for notifications,
    //                         in milliseconds. This field is only used as a hint
    //                         to conserve power, and actual time between location
    //                         updates may be greater or lesser than this value.
    //   Third(minDistance) :  the minimum distance interval for notifications, in meters
    //   Fourth(listener)   :  a {#link LocationListener} whose onLocationChanged(Location)
    //                         method will be called for each location update


    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
            3000,   // 3 sec
            10, this);

    /********* After registration onLocationChanged method  ********/
    /********* called periodically after each 3 sec ***********/
}

/************* Called after each 3 sec **********/
@Override
public void onLocationChanged(Location location) {

    lat = (EditText)findViewById(R.id.lat);
    lng = (EditText)findViewById(R.id.lng);
    lat.setText(""+location.getLatitude());
    lng.setText(""+location.getLongitude());

    String str = "Latitude: "+location.getLatitude()+"Longitude: "+location.getLongitude();

    Toast.makeText(getBaseContext(), str, Toast.LENGTH_LONG).show();
}


@Override
public void onProviderDisabled(String provider) {

    /******** Called when User off Gps *********/

    Toast.makeText(getBaseContext(), "GPS is OFF, Turn it on", Toast.LENGTH_LONG).show();
}

@Override
public void onProviderEnabled(String provider) {

    /******** Called when User on Gps  *********/

    Toast.makeText(getBaseContext(), "GPS ON ", Toast.LENGTH_LONG).show();
    Toast.makeText(getBaseContext(), "Waiting for location..... ", Toast.LENGTH_LONG).show();
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub

}




@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}
}    

这是当GPS获得定位时，获取位置并将LAT和LONG值填入输入框的代码

现在,，

我需要将所有数据发布到我的PHP页面中的代码。

如果有帮助的话。这并不是运行以下代码所需的全部异步任务。我希望您知道，为网络启用清单中的权限。 i、 e:

现在data是需要发送lat long数据的字符串

还有另一种向服务器发送数据的方法

   public HttpResponse YourMethod(String lat,String lon,Strig url) {
         HttpResponse response =null;
           // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new    HttpPost(url);

     try {

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair(<lat key from php>, lat));
    nameValuePairs.add(new BasicNameValuePair(<lat key from php>, lon));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));


    HttpResponse response = httpclient.execute(httppost);

     } catch (Exception e) {

   }
    finally{
       return response 
      }

 } 

public-HttpResponse-YourMethod（字符串lat、字符串lon、Strig-url）{
HttpResponse响应=null；
//创建一个新的HttpClient和Post头
HttpClient HttpClient=新的DefaultHttpClient（）；
HttpPost HttpPost=新的HttpPost（url）；
试一试{
List nameValuePairs=新的ArrayList（2）；
添加（新的BasicNameValuePair（，lat））；
添加（新的BasicNameValuePair（，lon））；
setEntity（新的UrlEncodedFormEntity（nameValuePairs））；
HttpResponse response=httpclient.execute（httppost）；
}捕获（例外e）{
}
最后{
返回响应
}
} 

查看此链接将值从android应用程序发送到php页面可能会有所帮助，，，，，，，，，，，，，，，，，，，，我们首先需要知道php端点接受什么-它是否获得JSON？它期望什么属性？如果它需要一个令牌或其他身份验证，您是否已经知道如何做到这一点？略去一些细节，比如URL，但是细节对于一个好的响应来说很重要。也可以使用这个lnk信息来获取关于Post方法和PHP服务的knwoladge。。谢谢，但我一点也不懂。什么是php中的lat键，YourMethod它是键。第二种方法是名称-值对，其中提供一个键及其对应的value@Kaushik：键是否与HTML中的“name”属性类似？@RaviPrakash请通过接收lat lon的php页面代码。准备好了吗？@Kaushik:不，先生，对不起，我弄错了。。。。。。更正后我会回复：）

   public HttpResponse YourMethod(String lat,String lon,Strig url) {
         HttpResponse response =null;
           // Create a new HttpClient and Post Header
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new    HttpPost(url);

     try {

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair(<lat key from php>, lat));
    nameValuePairs.add(new BasicNameValuePair(<lat key from php>, lon));
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));


    HttpResponse response = httpclient.execute(httppost);

     } catch (Exception e) {

   }
    finally{
       return response 
      }

 }
