ProgressDialog 解决“第一次执行图标转动，第二次执行不转动”代码：

@Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case PROGRESS_DIALOG:
            progressDialog = new ProgressDialog(LoginActivity.this);
            progressDialog.setMessage("正在登陆，请稍等...");
            progressDialog.setCancelable(true);
            // 设置ProgressDialog 是否可以按退回按键取消
            return progressDialog;
        default:
            return null;
        }
    }

    @Override
    protected void onPrepareDialog(int id, Dialog dialog) {
        switch (id) {
        case PROGRESS_DIALOG:
            dialog
                    .setOnDismissListener(new DialogInterface.OnDismissListener() {
                        @Override
                        public void onDismiss(DialogInterface dialog) {
                            removeDialog(PROGRESS_DIALOG);//这个起作用
                            if (progressThread != null) {
                                progressThread = null;
                            }
                        }
                    });
        }
    }
