Show Upload Progress For Json

I have the following piece of code and I would want to add a feature in here such that I know when the JSON content is uploaded. I am uploading a JSON content. @Override protected

Solution 1:

Initiate your progress bar as

private ProgressDialog pDialog;

On onPreExecute()

@OverrideprotectedvoidonPreExecute() {
            // TODO Auto-generated method stubsuper.onPreExecute();

            pDialog = newProgressDialog(getParent());
            pDialog.setMessage("Please wait ...");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(false);
            pDialog.show();
        }

On onPostExecute()

protected void onPostExecute(String result) {
            // TODO Auto-generated method stub
            super.onPostExecute(result);
pDialog.dismiss();
}

For showing progress bar with percentage try ..

publicclassAndroidDownloadFileByProgressBarActivityextendsActivity {

    // button to show progress dialog
    Button btnShowProgress;

    // Progress Dialogprivate ProgressDialog pDialog;
    ImageView my_image;
    // Progress dialog type (0 - for Horizontal progress bar)publicstaticfinalintprogress_bar_type=0; 

    // File url to downloadprivatestaticStringfile_url="your_url";

    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // show progress bar button
        btnShowProgress = (Button) findViewById(R.id.btnProgressBar);
        // Image view to show image after downloading
        my_image = (ImageView) findViewById(R.id.my_image);
        /**
         * Show Progress bar click event
         * */
        btnShowProgress.setOnClickListener(newView.OnClickListener() {

            @OverridepublicvoidonClick(View v) {
                // starting new Async TasknewDownloadFileFromURL().execute(file_url);
            }
        });
    }

    /**

        switch (id) {
        case progress_bar_type:

            pDialog.setMessage("Downloading file. Please wait...");
            pDialog.setIndeterminate(false);
            pDialog.setMax(100);
            pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            pDialog.setCancelable(true);
            pDialog.show();
            return pDialog;
        default:
            returnnull;
        }
    }
