Fragmandan Android Dialog

Question

Fragment'da LinearLayout'a tıklayarak diyaloğu açmaya çalıştım. Aslında bu eğiticiyi takip ediyorum: https://github.com/codepath/android_guides/wiki/Using-DialogFragment ve bununla birlikte, Etkinlik'te (oncreate) diyalog gösterisi var. Eğer onu parçalara ayırmaya çalışırsam işe yaramıyor.

package com.hgyghyfghyu.apkana40; 

import android.os.Bundle; 
import android.support.annotation.Nullable; 
import android.support.v4.app.DialogFragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.view.WindowManager; 
import android.widget.EditText; 
// ... 

public class EditNameDialog extends DialogFragment { 

    private EditText mEditText; 

    public EditNameDialog() { 
    } 

    public static EditNameDialog newInstance(String title) { 
     EditNameDialog frag = new EditNameDialog(); 
     Bundle args = new Bundle(); 
     args.putString("title", title); 
     frag.setArguments(args); 
     return frag; 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     return inflater.inflate(R.layout.fragment_edit_name, container); 
    } 

    @Override 
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { 
     super.onViewCreated(view, savedInstanceState); 
     mEditText = (EditText) view.findViewById(R.id.txt_your_name); 
     String title = getArguments().getString("title", "Enter Name"); 
     getDialog().setTitle(title); 
     mEditText.requestFocus(); 
     getDialog().getWindow().setSoftInputMode(
       WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE); 
    } 
} 

ve Fragment.java geçerli::

Dialog.java olduğunu

package com.hgyghyfghyu.apkana40;

import android.graphics.Color; 
import android.os.Bundle;

/**

*/ 
public class TrainerMenu extends Fragment { 


    public TrainerMenu() { 
     // Required empty public constructor 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 

     SharedPreferences pref = this.getActivity().getSharedPreferences("pref", Context.MODE_PRIVATE); 

     View v = inflater.inflate(R.layout.fragment_trainer_menu, container, false); 
     v.findViewById(R.id.trainermenuadbtn).setBackgroundColor(Color.parseColor(pref.getString(TRANSP_KEY, "#CC") + pref.getString(FCOLOR_KEY, "33777F"))); 
     v.findViewById(R.id.trainermenutrainersbtn).setBackgroundColor(Color.parseColor(pref.getString(TRANSP_KEY, "#CC") + pref.getString(FCOLOR_KEY, "33777F"))); 
     v.findViewById(R.id.trainermenusettingsbtn).setBackgroundColor(Color.parseColor(pref.getString(TRANSP_KEY, "#CC") + pref.getString(FCOLOR_KEY, "5556FF"))); 
     v.findViewById(R.id.trainermenuinfobtn).setBackgroundColor(Color.parseColor(pref.getString(TRANSP_KEY, "#CC") + pref.getString(FCOLOR_KEY, "5556FF"))); 
     v.findViewById(R.id.trainermenugroupsbtn).setBackgroundColor(Color.parseColor(pref.getString(TRANSP_KEY, "#CC") + pref.getString(FCOLOR_KEY, "5556FF"))); 


     return v; 
    } 

    public void onViewCreated (View view, Bundle savedInstanceState) { 
     LinearLayout btn = (LinearLayout) view.findViewById(R.id.pomocniczy); 
     btn.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       //DialogFragment dialog = new DialogFragment(getActivity()); 
       showEditDialog(); 
       return true; 
      } 
     }); 

    } 
    private void showEditDialog() { 
     android.support.v4.app.FragmentManager fm = getSupportFragmentManager(); 
     EditNameDialog editNameDialog = EditNameDialog.newInstance("Some Title"); 
     editNameDialog.show(fm, "fragment_edit_name"); 
    } 

} 

Ben bu sorunu yazdım hata

Error:(63, 53) error: cannot find symbol method getSupportFragmentManager() 

orada olduğunu ben yerine Fragment uzatmak kullandığından FragmentActivity ancak parçamı kontrol ettiğimde uzatmıyor, çalışmaz:

SharedPreferences pref = this.getActivity().getSharedPreferences("pref", Context.MODE_PRIVATE); 

Diyalog penceresinden açmanın en iyi yolu nedir?

Answer 1

kullanımı bu:

android.support.v4.app.FragmentManager fm = getActivity().getSupportFragmentManager(); 

aktivite bağlamı
