андроид фрагмент может не setvisibility RelativeLayout

Question

I usging фрагментов, и в своей деятельности я хочу показать/скрыть в RelativeLayout (последний: xk1), когда я коснуться EditText:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/xMLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/linearborder" > 


    <RelativeLayout 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/xsubLayout" 
     android:keepScreenOn="true" 
     android:orientation="vertical" 
     android:layout_below="@+id/RL_boutton" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" > 
     <EditText 
      android:id="@+id/editText_code_d" 
      android:layout_width="304dp" 
      android:layout_height="wrap_content" 
      android:layout_below="@+id/RL_boutton" 
      android:layout_centerHorizontal="true" 
      android:background="@drawable/plaquehaut" 
      android:ems="4" 
      android:gravity="center_vertical|center_horizontal" 
      android:inputType="number" 
      android:maxLength="4" 
      android:text="123" 
      android:textSize="80sp" 
      android:focusableInTouchMode="true" 
      /> 

     <EditText 
      android:id="@+id/editText_code_m" 
      android:layout_width="304dp" 
      android:layout_height="wrap_content" 
      android:layout_alignLeft="@+id/editText_code_d" 
      android:layout_below="@+id/editText_code_d" 
      android:background="@drawable/plaquebas" 
      android:ems="4" 
      android:gravity="center_vertical|center_horizontal" 
      android:inputType="number" 
      android:maxLength="4" 
      android:text="1337" 
      android:textSize="80sp" 
      /> 
    </RelativeLayout> 
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="wrap_content" 
       android:id="@+id/xK1" 
     android:layout_height="wrap_content" 
       android:orientation="vertical" 
     android:visibility="gone"> 
     <include android:id="@+id/xKeyBoard" 
        layout="@layout/keyboard"> 
       </include> 
    </RelativeLayout> 
</RelativeLayout> 

Вот код:

public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    { 
     View view = inflater.inflate(R.layout.fragment_rsslist_overview,container, false); 
       try { 
        mLayout = (RelativeLayout) view.findViewById(R.id.xK1); 
        mKLayout = (RelativeLayout) view.findViewById(R.id.xKeyBoard); 

       } catch (Exception e) { 
        Log.w(getClass().getName(), e.toString()); 
       } 
     mEt = (EditText) view.findViewById(R.id.editText_code_d); 
     mEt.setOnClickListener(new View.OnClickListener() 
     { 
      @Override 
      public void onClick(View v) 
      { 
       edittext_onClick(v); 
      } 
     });  
     mEt1 = (EditText) view.findViewById(R.id.editText_code_m); 
     mEt1.setOnClickListener(new View.OnClickListener() 
     { 
      @Override 
      public void onClick(View v) 
      { 
       edittext_onClick(v); 
      } 
     }); 
     mEt.setOnTouchListener(this); 
     return view; 
    } 

    public boolean onTouch(View v, MotionEvent event) { 
      enableKeyboard(); 
      return true; 
    } 

    private void enableKeyboard() { 
     mLayout.setVisibility(RelativeLayout.VISIBLE); 
     mKLayout.setVisibility(RelativeLayout.VISIBLE); 

    } 

деятельность прекращается, когда программа работает здесь: mLayout.setVisibility (RelativeLayout.VISIBLE);

Как я могу решить эту проблему?

thx, заранее.

Answer 1

Вы должны только определить следующие за вид сверху: Xmlns: андроид = "http://schemas.android.com/apk/res/android" Я думаю, что это, почему ты получить nullpointerexception, поскольку layoutinflater не может найти правильный взгляд на hierachy.
