Question

这是我的代码

class BuatPeminjaman extends AsyncTask<String, String, String> {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(DetailsActivity.this);
        pDialog.setMessage("Booking...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();
    }

    @Override
    protected String doInBackground(String... arg) {
        int success;
        try {
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            params.add(new BasicNameValuePair("gedung", gedung));
            params.add(new BasicNameValuePair("lantai", lantai));
            params.add(new BasicNameValuePair("nim", nim));
            params.add(new BasicNameValuePair("nama", nama));
            params.add(new BasicNameValuePair("jumlah peserta", peserta));
            params.add(new BasicNameValuePair("keperluan", keperluan));
            params.add(new BasicNameValuePair("ruang", ruang));
            Log.d("request!", "starting");
            JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "GET", params);
            // checking log for json response
            Log.d("proses membuat", json.toString());
            // success tag for json
            success = json.getInt(TAG_SUCCESS);
            if (success == 1) {
                Log.d("Berhasil membuat !", json.toString());
                return json.getString(TAG_MESSAGE);
            } else {
                return json.getString(TAG_MESSAGE);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String message) {
        pDialog.dismiss();
        Toast.makeText(DetailsActivity.this, "Berhasil meminjam kelas", Toast.LENGTH_SHORT).show();
        Intent i = new Intent(DetailsActivity.this, MainActivity.class);
        startActivity(i);
    }
}

我不知道错误是什么意思。 我已经在我的对话框中调用了dismiss ，但它仍然无效。它显示了对话框，但在此之后强制关闭。我有错误是因为我试图发布的JSON还是什么？

这是我的logcat

请帮忙。或者，如果您有任何建议如何将数据发布到数据库而没有错误，那就没问题

Answer 1

您退出活动后尝试显示对话框。

在退出之前，在您创建的Dialog实例上调用dismiss（）活动，例如在onPause（）或onDestroy（）
