android 网络之 httppost

android中使用http协议进行通信

以下的一个例子，是我G06的android测试代码

public class MainActivity extends Activity {
/** Called when the activity is first created. */

private static final int STATE_21 = 0x21;
private static final int STATE_22 = 0x22;
private static final int STATE_01 = 0x01;
private static final int STATE_02 = 0x02;
private static final int STATE_31 = 0x31;

private static int iCurrentState = STATE_21;

private static final String strUrl = "http://XXX.XXX.XXX.XXX:8080/terminal/gprs";//00 11s
private static final String strUserAgent = "13800138000";
private Button btn;
private Button btn2;
private TextView textView;
private EditText editText;
private String strData;

private Handler handler = new Handler()
{
@Override
public void handleMessage(Message msg )
{
switch(msg.what)
{
case STATE_22:
ConstructHttpBody("[201202201357250002,T01,29,13486108318@4@1;2;3;4@1@1@1@1]");
break;

case STATE_02:
ConstructHttpBody("[201202201357250002,T31,1,0]");
break;
}
}
};

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

InitWidget();

btn2.setOnClickListener( new Button.OnClickListener()
{
@Override
public void onClick(View v )
{
try
{
if( iCurrentState == STATE_21 )
ConstructHttpBody("[201201172244290000,T21,55,16@222222333335555@460020863831969@89860048111151031969]");
}
catch(Exception e )
{
Log.e("XXX",e.toString());
}
}
}
);
}

private void ConstructHttpBody(String strBody)
{
HttpPost httpRequest = new HttpPost(strUrl);
httpRequest.setHeader("User Agent",strUserAgent);

try
{
StringEntity strEntity = new StringEntity(strBody,HTTP.UTF_8);
httpRequest.setEntity(strEntity);
HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);

int ret = httpResponse.getStatusLine().getStatusCode();

if(ret == 200 )
{
Message msg = new Message();
String str = EntityUtils.toString(httpResponse.getEntity());

textView.setText(str);

if( str.indexOf("T22",0) > 0 )
{
msg.what = STATE_22;
msg.obj = str;
}
else if( str.indexOf("T02",0) > 0 )
{
msg.what = STATE_01;
msg.obj = str;
}

handler.sendMessage(msg);
}
else
{
Toast.makeText(MainActivity.this,""+ ret ,Toast.LENGTH_SHORT).show();
}
}
catch(Exception e )
{
}
}

private void InitWidget()
{
btn = (Button)findViewById(R.id.btn);
btn2 = (Button)findViewById(R.id.btn2);
textView = (TextView)findViewById(R.id.text);
editText = (EditText)findViewById(R.id.edit);
}

@Override
protected void onDestroy()
{
super.onDestroy();
System.gc();
System.exit(0);
}
}
