android - ProgressDialog 工作但在图标(滚轮)中没有进展

Question

我正在使用一个简单的 progressDialog，它运行正常但轮子没有进步:

    //Progress Dialog
            final ProgressDialog dialog = ProgressDialog.show(TravelPharm.this, "Searching","Please wait ...", true);
            ((ProgressDialog) dialog)
            .setProgressStyle(ProgressDialog.BUTTON_NEUTRAL);

            final Handler handler = new Handler() {
                       public void handleMessage(Message msg) {
                          dialog.dismiss();
                          }
                       };
                    Thread checkUpdate = new Thread() {  
                       public void run() {

                          handler.sendEmptyMessage(0);
                          }
                       };
                    checkUpdate.start();

我错过了什么？？

像这样创建你的进度对话框:

final ProgressDialog progress = new ProgressDialog(context);

向其中添加一些文本/图标:

progress.setTitle("Loading");
progress.setMessage("Loading, please wait");
progress.setIcon(R.drawable.icon);

显示它:

progress.show();
