Question

我在对话框中使用自定义布局。这是util java（非活动）中的一种方法。

public void showLoadingProgress(String msg){
    Log.d("EditorUtil", "show loading progress"+progressDialog);//No i18n
    if(progressDialog!=null && progressDialog.isShowing()){
        TextView message = (TextView)progressDialog.findViewById(R.id.progressmsg);
        message.setText(msg);
        return;
    }

Context context = EditorActivity.getActivity().getApplicationContext();
progressDialog = new Dialog(EditorActivity.getActivity().getApplicationContext());
progressDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
progressDialog.setCancelable(false);
progressDialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
progressDialog.setContentView(R.layout.customprogress);

TextView message = (TextView)progressDialog.findViewById(R.id.progressmsg);
message.setText(msg);

progressDialog.show();
Log.d("",progressDialog.isShowing()+""); //No i18n

}

我有一个像

要显示来自非Activity调用的progressDialog，您需要将当前活动上下文而不是Application Context传递给Dialog Constructor。您可以通过添加一个参数来将Activity上下文传递给showLoadingProgress：

public void showLoadingProgress(String msg,Context context){

 //.....
progressDialog = new Dialog(context);
 //.....

}

现在将EditorActivity.getActivity()作为第二个参数传递给showLoadingProgress方法

显示对话框时出现异常
