As David said, you need an AsynTask, most practical option. You can do some clever things with the Void, Void, Void part, but unless you want to look into the documentation, this should work fine.

public class MyActivity extends Activity {

....

    private final class AsyncSender extends AsyncTask<Void, Void, Void> {

        ProgressDialog pd;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            pd = new ProgressDialog(MyActivity.this);
            pd.setTitle("Sending Data");
            pd.setMessage("Please wait, data is sending");
            pd.setCancelable(false);
            pd.setIndeterminate(true);
            pd.show();
        }

        @Override
        protected Void doInBackground(Void... params) {
            send_data(); // You probably have to try/catch this
            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            super.onPostExecute(result);
            pd.dismiss();
        }
    }
}

那么,当你打电话时,最干净的方式就是呼吁。

new AsyncSender().execute();

此外,我还要提到,这应该是内部的阶层,也就是说,不会为它单独立案。 总的来说,我只是把他们放在Im的班底部。

You are blocking the UI with your upload code. You need to use an AsyncTask / thread / service.

http://android-developers.blogspot.co.uk/2009/05/painless-threading.html” rel=“nofollow”>Painless Threading

First of all you call ProgressDialog.show() twice which is unnecessary. And perhaps one reason why it doesn t show is because it is dismissed right after it is shown. For instance if your file upload is really fast or fails or is done in another thread the call to dismiss() will be called so quickly that you won t be able to ever see the dialog.

When you want to do any task in background and want to show another thing on screen the you should use AsyncTask...

This is an example of login using AsyncTask now u can update it...

public class mytask extends AsyncTask<Object, Object, Object> {

    String METHOD_NAME = "Login";
    String NAMESPACE = "http://tempuri.org/";
    SoapObject request;
    String SOAP_ACTION = "http://tempuri.org/Login";
    @Override
    protected Object doInBackground(Object... params) {
        Log.d(TAG, "doInBackground(Void... params");
        Object flag = null;
        try {
            flag = TAGS.sendToServerAndGetResponse(request, SOAP_ACTION);
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            e.printStackTrace();
        }
        return flag;
    }

    @Override
    protected void onPostExecute(Object result) {
        if (result.toString().equalsIgnoreCase("true")) {

            mIntent = new Intent();
            mIntent.setClass(PresenTABActivity.this,
                    presentation_list.class);
            startActivity(mIntent);
            finish();
        } else {
            Toast.makeText(getApplicationContext(),
                    "Please Enter Valid Username or Password",
                    Toast.LENGTH_SHORT).show();
            edtPass.setVisibility(View.VISIBLE);
            edtUname.setVisibility(View.VISIBLE);
            chk_remeber_me.setVisibility(View.VISIBLE);
            btnSubmit.setVisibility(View.VISIBLE);
            mProgressBar.setVisibility(View.INVISIBLE);
            loading.setVisibility(View.INVISIBLE);
        }
    }

    @Override
    protected void onPreExecute() {
        Log.d(TAG, "onPreExecute()");
        request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("Username", edtUname.getText().toString()
                .trim());
        request.addProperty("password", edtPass.getText().toString().trim());

        mProgressBar = (ProgressBar) findViewById(R.id.progress_login);
        loading = (TextView) findViewById(R.id.tv_loading);
        loading.setVisibility(View.VISIBLE);
        mProgressBar.setVisibility(View.VISIBLE);

        edtPass.setVisibility(View.INVISIBLE);
        edtUname.setVisibility(View.INVISIBLE);

        chk_remeber_me.setVisibility(View.INVISIBLE);
    }
}

例

private class UploadingTask extends AsyncTask<Void, Void, Void> {

private ProgressDialog mProgressDialog;

    @Override
    protected void onPreExecute() {
        mProgressDialog = ProgressDialog.show(this, title, message, true);
    }

    @Override
    protected Void doInBackground(final Void... params) {
        // Do your work .. uploading
        return null;
    }

    @Override
    protected void onPostExecute(final Void result) {
        if (mProgressDialog != null) {
        mProgressDialog.dismiss();
        }
    }
}
