自定義視圖 - 條件視圖 - ViewStub和單選按鈕

我正在創建一個自定義視圖，該視圖基於條件「是」或「否」填充，通過RadioButtons & ViewStub實現。不幸的事情不會按計劃進行：自定義視圖 - 條件視圖 - ViewStub和單選按鈕

CustomView - artooConditional：

public artooConditional(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     setAttributes(attrs); 
    } 

    private void setAttributes(AttributeSet attrs) { 
     TypedArray a = getContext().obtainStyledAttributes(attrs, 
       R.styleable.artooConditional); 
     mLayout = a.getResourceId(R.styleable.artooConditional_layout, NO_ID); 

     LayoutInflater inflater = (LayoutInflater) getContext() 
       .getSystemService(getContext().LAYOUT_INFLATER_SERVICE); 

     View v = inflater.inflate(R.layout.types_conditional, null, false); 
     addView(v, new LayoutParams(LayoutParams.FILL_PARENT, 
       LayoutParams.WRAP_CONTENT)); 

     RadioGroup group = (RadioGroup) v 
       .findViewById(R.id.types_conditional_group); 
     layout = (ViewStub) v.findViewById(R.id.types_conditional_layout); 

     group.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

      @Override 
      public void onCheckedChanged(RadioGroup group, int checkedId) { 
       if (checkedId == R.id.types_conditional_yes) { 
        if (!inflated) { 
         layout.setLayoutResource(mLayout); 
         layout.inflate(); 
         inflated = true; 
        } 
        // layout.setVisibility(View.VISIBLE); 
       } else { 
        // if (layout.getVisibility() != View.GONE) 
        layout.setVisibility(View.GONE); 
        inflated = false; 
       } 

      } 
     }); 
     a.recycle(); 
    }

支持XML佈局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:a="http://schemas.android.com/apk/res/com.android.artoo.types.buttondialog" 
    android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical"> 
    <RadioGroup android:layout_width="fill_parent" 
     android:layout_height="wrap_content" android:orientation="horizontal" android:id="@+id/types_conditional_group"> 
     <RadioButton android:layout_width="wrap_content" 
      android:layout_height="wrap_content" android:text="Yes" android:layout_weight="1" android:id="@+id/types_conditional_yes"/> 
     <RadioButton android:layout_width="wrap_content" 
      android:layout_height="wrap_content" android:text="No" android:layout_weight="1" android:id="@+id/types_conditional_no"/> 
    </RadioGroup> 
    <ViewStub android:layout_width="fill_parent" 
     android:layout_height="wrap_content" android:id="@+id/types_conditional_layout" android:visibility="gone"/> 
</LinearLayout>

我可以看到，第一當ViewStub被誇大時，其父項變爲空值，因此在單擊「Y」時會導致錯誤點擊「否」後點擊「es」。什麼是創建這種觀點的最佳方式？

任何幫助將不勝感激。由於

薩米爾做你解決了這個根觀的好處？你能幫我指導一下嗎？我面臨着類似的情況。請幫忙。 – 2012-07-20 11:06:20

我有類似的問題發佈http://stackoverflow.com/questions/11578653/viewstub-raises-error-while-inflating-more-than-one-layouts-conditionally請回答。 – 2012-07-20 13:02:36

使用

View importPanel = ((ViewStub) findViewById(R.id.stub_import)).inflate();

爲inflate()方法返回充氣佈局
