Question

进度对话框微调器无缝旋转。我希望它是这样的 - 用户单击“Check For Root”按钮，微调器将旋转5秒并显示“Please wait”消息，然后显示带有结果的对话框。请帮忙！

您的代码似乎没问题。我不确定那是什么问题。我想建议以下内容。值得一试。

    private static final int SHOW_PROGRESS = 0x1;
    private static final int STOP_PROGRESS = 0x2;

  Root.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {

    mHandler.sendEmptyMessageDelayed(SHOW_PROGRESS);
    mHandler.sendEmptyMessage(STOP_PROGRESS, 5000);
        }
    });

// Handler
private Handler mHandler = new Handler() {

    @Override
    public void handleMessage(Message msg) {
        // TODO Auto-generated method stub
        switch (msg.what) {
        case SHOW_PROGRESS:
             // Show your progress Bar here.
            mHandler.removeMessages(SHOW_PROGRESS);
            break;

        case STOP_PROGRESS:
            progressDialog.dismiss();
              if (RootTools.isAccessGiven()) {
                AlertDialog.Builder builder = new         AlertDialog.Builder(MainActivity.this);
                builder.setIcon(R.drawable.ic_launcher);
                builder.setTitle("Congratulations!");
                builder.setMessage("You Have Root Access!");

                builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                });

                AlertDialog dialog = builder.create();
                dialog.show();
            }

        else  {
             AlertDialog.Builder builder1 = new AlertDialog.Builder(MainActivity.this);
                builder1.setIcon(R.drawable.ic_launcher);
                builder1.setTitle("Oops!");
                builder1.setMessage("No Root Access!");
                builder1.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {

                    public void onClick(DialogInterface dialog, int which) {

                        dialog.cancel();
                    }
                });

                AlertDialog dialog = builder1.create();
                dialog.show();  
            mHandler.removeMessages(STOP_PROGRESS);
            break;
        }
        super.handleMessage(msg);
    }
};
