我使用android将图像从我的android模拟器发送到服务器（我的本地机器）
MainActivity.java
public class MainActivity extends Activity {
Button submit;
ProgressDialog pDialog;
ImageView imageView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
submit = (Button) findViewById(R.id.SUBMIT_BUTTON_ID);
imageView = (ImageView) findViewById(R.id.imageView1);
submit.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new MainTest().execute();
}
});
}
/**
* Method to post the image to the server.
* U will have to change the url which will accept the image data.
* @throws IOException
*/
public void postImageData() throws IOException
{
Drawable myDrawable = getResources().getDrawable(R.drawable.image);
Bitmap bitmap = ((BitmapDrawable)myDrawable).getBitmap();
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost("http://127.0.0.1/Details/");
MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
try{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");
reqEntity.addPart("key", bab);
}
catch(Exception e){
//Log.v("Exception in Image", ""+e);
reqEntity.addPart("key", new StringBody(""));
}
postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();
while ((sResponse = reader.readLine()) != null) {
s = s.append(sResponse);
}
}
public class MainTest extends AsyncTask<String, Integer, String> {
@Override
protected void onPreExecute() {
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setMessage("Loading..");
pDialog.setIndeterminate(true);
pDialog.setCancelable(false);
pDialog.show();
}
@Override
protected String doInBackground(String... params) {
try {
postImageData();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
// data=jobj.toString();
pDialog.dismiss();
}
}
}
