我想通過後PHP發送圖像和字符串。我已經添加外部罐httpclientandroidlib-1.1.2.jar但它一直崩潰，我試着兩個代碼下面但仍然崩潰。下面的代碼需要snapsot，然後按下按鈕上傳它應該上傳。我真的很感激任何幫助。感謝提前。上傳圖像和字符串發佈方法android（ics）
Button btn=(Button)findViewById(R.id.snapshot);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent i=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, 0);
}
});
uploadButton=(Button)findViewById(R.id.uploadButton);
uploadButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (finalFile!=null) {
HttpPost httpost = new HttpPost("http://example/test.php");
MultipartEntity entity = new MultipartEntity();
try {
entity.addPart("name", new StringBody("test"));
} catch (UnsupportedEncodingException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
entity.addPart("image", new FileBody(finalFile));
httpost.setEntity(entity);
HttpResponse response;
HttpClient httpclient = null;
try {
response = httpclient.execute(httpost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
// super.onActivityResult(requestCode, resultCode, data);
if (requestCode==0) {
if (data!=null) {
Bitmap bt=(Bitmap) data.getExtras().get("data");
Uri tempUri = getImageUri(getApplicationContext(), bt);
finalFile = new File(getRealPathFromURI(tempUri));
}
}
}
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}
public String getRealPathFromURI(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
而且下面的代碼不工作我已經試過這兩個代碼：
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://example/test.php");
try {
MultipartEntity entity = new MultipartEntity();
entity.addPart("name", new StringBody("test"));
entity.addPart("image", new FileBody(finalFile));
httppost.setEntity(entity);
HttpResponse response = httpclient.execute(httppost);
Log.e("test", "SC:" + response.getStatusLine().getStatusCode());
HttpEntity resEntity = response.getEntity();
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);
}
Log.e("test", "Response: " + s);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
其中一個logcat的錯誤：

發佈您的logcat，因爲它崩潰！ –
