吐司没有显示

Question

我使用的凌空抽射为网络呼叫吐司没有显示

---

土司凌空请求没有显示。我不知道如何从片段中获取警报对话框中的上下文。所以请给我一个解决方案，让我可以在凌空响应中打印吐司。

public class TiffinMenuFragment extends DialogFragment { 
@Override 
public Dialog onCreateDialog(Bundle savedInstanceState) { 
    final AlertDialog.Builder alertdialog = new AlertDialog.Builder(getActivity()); 
     LayoutInflater inflater = (LayoutInflater) getActivity().getBaseContext() 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    View v = inflater.inflate(R.layout.fragment_tiffinlayout, null); 
    alertdialog.setView(v); 
    alertdialog.setCancelable(false); 


    final AlertDialog dialog = alertdialog.create(); 

    add.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(final View view) { 
      String type=selectmenu.getSelectedItem().toString(); 
      Log.v("java1",type); 


      String url_menu=UrlString.url_string; 
      url_menu = url_menu.replace(" ", "%20"); 
      Log.v("url",url_menu); 
      final StringRequest stringRequest=new StringRequest(Request.Method.GET, url_menu, new Response.Listener<String>() { 
       @Override 
       public void onResponse(String response) { 
        Log.v("Response",response); 
        JSONObject obj= null; 
        try { 
         obj = new JSONObject(response); 
         String objResponse=obj.getString("success"); 
         Log.v("Response1",objResponse); 
         Toast.makeText(view.getContext(),"Task is Completed",Toast.LENGTH_LONG).show(); 
        } catch (JSONException e) { 
         e.printStackTrace(); 
        } 

       } 
      }, new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
       Log.v("type",error.getMessage()); 
       } 
      }); 
      MySingleton.getInstance(getActivity().getApplicationContext()).addToRequestque(stringRequest); 
      dialog.dismiss(); 

     } 
    }); 
    cancle.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      dialog.dismiss(); 

     } 
    }); 




    return dialog; 

} 
} 

Answer 1

只是做你用吐司

Toast.makeText(getActivity(),"Text!",Toast.LENGTH_SHORT).show(); 

Answer 2

您背景下，不低于一个

Toast.makeText(getActivity(),"Task is Completed",Toast.LENGTH_LONG).show(); 

Answer 3

   Toast.makeText(dialog.getContext(),"Task is Completed",Toast.LENGTH_LONG).show(); 

使用此正确使用。

Answer 4

你不能触摸UI从后台线程

要显示敬酒使用此代码

activity.runOnUiThread(new Runnable() { 
    public void run() { 
     Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show(); 
    } 
}); 

或请求得到失败，而不是调用该onResponse功能。

Answer 5

使用：

Toast.makeText(getActivity().getApplicationContext(),"Task is 
Completed",Toast.LENGTH_LONG).show(); 

Answer 6

Toast.makeText(dialog.getActivity(),"Task is Completed",Toast.LENGTH_LONG).show();
