android - Android は読み込み中のビューを AysncTask に追加します

Question

こんにちは、すべてが読み込まれるまで画面が空白になるという問題のみを処理する Asynctask があるので、loadingcell ビューを作成しましたが、すべてが読み込まれるまで読み込みビューを表示する方法を知りたいです。

ここで私が試したことはありますが、うまくいきません

public class PostTask extends AsyncTask<Void, String, Boolean> {



        @Override
        protected Boolean doInBackground(Void... params) {
            boolean result = false;


            loadFixtures();
            publishProgress("progress");
            loadResultsFeed();
            publishProgress("progress");
            loadNewsFeed();
            publishProgress("progress");
            return result;
        }


        protected void onProgressUpdate(String... progress) {
            StringBuilder str = new StringBuilder();
                for (int i = 1; i < progress.length; i++) {
                    str.append(progress[i] + " ");

                  loadingView = LayoutInflater.from(getBaseContext()).inflate(R.layout.loadingcell,
                         null);

                }
        }

            @Override
        protected void onPostExecute(Boolean result) {
            super.onPostExecute(result);
            Log.v("BGThread", "begin fillin data");
             FillData();
        }
    }

Answer 1

protected void onPostExecute(Boolean result) {
        super.onPostExecute(result);
        Log.v("BGThread", "begin fillin data");
         FillData();
     // hide your view here                                <---------
     // for ex:    
      progressbar.setVisibility(View.GONE);                <---------

    }

これを試して。

private class BackgroundTask1 extends
        AsyncTask<String, Void, String> {

private ProgressDialog dialog;

    protected void onPreExecute() {
        /** Initialise progress dialog and show*/
        dialog = new ProgressDialog(currentActivity.this);
        dialog.setMessage("Loading.....");
        dialog.setCancelable(false);
        dialog.show();
    }


    protected String doInBackground(final String... args) {
        // do your stuff
               return anyString // as an example

    }


    protected void onPostExecute(String temp) {
        Log.v("String:::::",temp);
        dialog.dismiss();  // dismiss progress dialog
    }
}

私はこのようにしました。参照できます

 private class DownloadingProgressTask extends
        AsyncTask<String, Void, Boolean> {

    private ProgressDialog dialog = new ProgressDialog(ShowDescription.this);


    protected void onPreExecute() {
        this.dialog.setMessage("Please wait");
        this.dialog.show();         

    }

    protected Boolean doInBackground(final String... args) {
        try {
            downloadFile(b.getString("URL"));
            return true;
        } catch (Exception e) {
            Log.e("tag", "error", e);
            return false;
        }
    }

    @Override
    protected void onPostExecute(final Boolean success) {

        if (dialog.isShowing()) {
            dialog.dismiss();
        }

        if (success) {
            Toast.makeText(ShowDescription.this,
                    "File successfully downloaded", Toast.LENGTH_LONG)
                    .show();
            imgDownload.setVisibility(8);
        } else {
            Toast.makeText(ShowDescription.this, "Error", Toast.LENGTH_LONG)
                    .show();
        }
    }

}
