变化在DialogFragment ProgressDialog的字体字样 [英] Change font typeface of ProgressDialog within DialogFragment

问题描述

我可以知道是否有可能改变 ProgressDialog 的消息显示的字体字样，在 DialogFragment ？

 公共类LoadFromCloudTaskFragment扩展DialogFragment {    @覆盖
    公共对话框onCreateDialog（捆绑savedInstanceState）{
        this.progressDialog =新ProgressDialog（this.getActivity（））;
        this.progressDialog.setMessage（progressMessage）;
        this.progressDialog.setCanceledOnTouchOutside（假）;        返回progressDialog;
    }
 

从 ProgressDialog 继承创建一个自定义类可能的途径之一。不过，我想知道有没有更好的选择吗？可悲的是，我们没有 ProgressDialog.Builder 。

一个我曾试图替代的是

  @覆盖
公共对话框onCreateDialog（捆绑savedInstanceState）{
    this.progressDialog =新ProgressDialog（this.getActivity（））;
    this.progressDialog.setMessage（progressMessage）;
    this.progressDialog.setCanceledOnTouchOutside（假）;    Utils.setCustomFont（this.progressDialog.findViewById（android.R.id.message），Utils.ROBOTO_LIGHT_FONT）;    返回progressDialog;
}
 

但是，这会给我误差

  

android.util.AndroidRuntimeException：requestFeature（）必须被调用
  添加内容之前

解决方案

一个建议的解决方案是如下。但我不认为这是一个好办法。任何进一步的建议都非常欢迎。

 公共类ProgressDialogEx扩展ProgressDialog {
    公共ProgressDialogEx（上下文的背景下）{
        超级（上下文）;
    }    @覆盖
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        查看查看= this.findViewById（android.R.id.message）;
        如果（查看！= NULL）{
            //不应为null。只是要偏执足够了。
            Utils.setCustomFont（查看，Utils.ROBOTO_LIGHT_FONT）;
        }
    }
}

 公共类LoadFromCloudTaskFragment扩展DialogFragment {    @覆盖
    公共对话框onCreateDialog（捆绑savedInstanceState）{
        this.progressDialog =新ProgressDialogEx（this.getActivity（））;
        this.progressDialog.setMessage（progressMessage）;
        this.progressDialog.setCanceledOnTouchOutside（假）;        返回progressDialog;
    }
 

May I know is it possible to change the font typeface of ProgressDialog's message display, within DialogFragment?

public class LoadFromCloudTaskFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        this.progressDialog = new ProgressDialog(this.getActivity());
        this.progressDialog.setMessage(progressMessage);
        this.progressDialog.setCanceledOnTouchOutside(false);

        return progressDialog;
    }

Create a custom class by inheriting from ProgressDialog might be one of the ways. However, I wish to know is there any better alternative? Sadly, we do not have ProgressDialog.Builder.

One of the alternative I had tried is

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    this.progressDialog = new ProgressDialog(this.getActivity());
    this.progressDialog.setMessage(progressMessage);
    this.progressDialog.setCanceledOnTouchOutside(false);

    Utils.setCustomFont(this.progressDialog.findViewById(android.R.id.message), Utils.ROBOTO_LIGHT_FONT);

    return progressDialog;
}

But this will give me error

android.util.AndroidRuntimeException: requestFeature() must be called before adding content

解决方案

One of the suggested solution is as follow. But I don't think this is a good way. Any further suggestion are very much welcomed.

public class ProgressDialogEx extends ProgressDialog {
    public ProgressDialogEx(Context context) {
        super(context);
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View view = this.findViewById(android.R.id.message);
        if (view != null) {
            // Shouldn't be null. Just to be paranoid enough.
            Utils.setCustomFont(view, Utils.ROBOTO_LIGHT_FONT);
        }
    }
}

public class LoadFromCloudTaskFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        this.progressDialog = new ProgressDialogEx(this.getActivity());
        this.progressDialog.setMessage(progressMessage);
        this.progressDialog.setCanceledOnTouchOutside(false);

        return progressDialog;
    }
