Question

我试图在TabLayout的2个片段中使用this第三方库来显示自定义进度条。我在后台显示进度条我正在进行排球请求。问题是即使从Web服务加载结果后，进度条也没有隐藏。当我使用常规progressdialog与TabLayout时不会发生此问题。虽然此自定义进度条在正常布局中工作正常，但它在TabLayout中不起作用。这有什么特别的原因吗？感谢。

Answer 1

试试这个，

  public void hideProgress() {
    if (m_Dialog != null) {
        m_Dialog.setVisible(View.GONE);
        m_Dialog = null;
    }
}

或onResponse()

 cShowProgress.setVisible(View.GONE);

Answer 2

我在自定义进度对话框类中进行了一些更改，现在它可以正常运行...

＆＃13;

public class CShowProgress extends Dialog{
    private Dialog mpd = null;
    private LayoutInflater inflater = null;

    public CShowProgress(Context context) {
        super(context)
    }

    

    public void showProgress(Context context) {
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        final View view = inflater.inflate(R.layout.custom_progress_layout, null);

        mpd = new Dialog(context);
        mpd.requestWindowFeature(Window.FEATURE_NO_TITLE);
        mpd.setContentView(view);
        mpd.findViewById(R.id.progress_bar).setVisibility(View.VISIBLE);
        mpd.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
        mpd.setCancelable(true);
        mpd.show();
    }

    public void hideProgress() {
        if (mpd != null) {
            if (mpd.isShowing()){
                mpd.dismiss();
            }
        }
    }
}
