Question

E/AndroidRuntime（5149）：android.view.InflateException：バイナリXMLファイル行＃44：エラーが発生しましたクラスcom.android.demoapp.View.GridCustomView E/AndroidRuntime（5149）：android.view.LayoutInflater.createViewFromTag（LayoutInflater.java:757）

で....

<com.android.demoapp.customView.GridCustomView 
       android:id="@+id/myId" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:gravity="center"

       android:numColumns="4" 
       android:stretchMode="columnWidth" 
       android:verticalSpacing="20dp" /> 

アダプタビューを作成する：

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

      // Check if an existing view is being reused, otherwise inflate the view 
     ContactBlock user = getItem(position); 

     if(convertView==null) 
       { 
       convertView = inflter.inflate(R.layout.viewtemplate,null); 

       } 


     conviewname = (TextView) convertView.findViewById(R.id.conname); 
      conviewnumb = (TextView) convertView.findViewById(R.id.connumber); 
     // TextView al = (TextView) convertView.findViewById(R.id.alpha); 
     // grid = (GridView) convertView.findViewById(R.id.grid_view); 

     gridCustomView = (GridCustomView) convertView.findViewById(R.id.myId); 
     gridCustomView.setExpanded(true); 


      //al.setText(user.name.substring(0, 1)); 
     // al.setText(alpha); 
     conviewname.setText(user.getInitial().toUpperCase()); 
     //conviewnumb.setText(""+user.getContacts().size()); 

     gridadapter= new GridAdapter(context, user.getContacts()); 

     // grid.setAdapter(gridadapter); 

      gridCustomView.setAdapter(gridadapter); 




     return convertView; 
    } 

......................

public class GridCustomView extends GridView { 
    boolean expanded = false; 

    public GridCustomView(Context context) { 
     super(context); 
     // TODO Auto-generated constructor stub 
    } 

    public GridCustomView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     // TODO Auto-generated constructor stub 
    } 

    public GridCustomView(Context context, AttributeSet attrs, int defaultStyle) { 
     super(context); 
    } 

    public boolean isExpanded() { 

     return expanded; 
    } 

    @Override 
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     // HACK! TAKE THAT ANDROID! 
     if (isExpanded()) { 
      // Calculate entire height by providing a very large height hint. 
      // viewCustom.MEASURED_SIZE_MASK represents the largest height possible. 
      int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK, 
        MeasureSpec.AT_MOST); 
      super.onMeasure(widthMeasureSpec, expandSpec); 

      ViewGroup.LayoutParams params = getLayoutParams(); 
      params.height = getMeasuredHeight(); 
     } else { 
      super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
     } 
    } 

    public void setExpanded(boolean expanded) { 
     this.expanded = expanded; 
    } 

}

はコードの下に試してみてください：

@Override 
public View getView(final int position, View convertView, ViewGroup parent{ 
    final ViewHolder holder; 
    ContactBlock user = getItem(position); 
    if (convertView == null) { 
     holder = new ViewHolder(); 

     convertView = inflter.inflate(R.layout.viewtemplate,null); 
     holder.conviewname = (TextView) convertView.findViewById(R.id.conname); 
     holder.conviewnumb = (TextView) convertView.findViewById(R.id.connumber); 
     holder.gridCustomView = (GridCustomView) convertView.findViewById(R.id.myId); 
     holder.gridCustomView.setExpanded(true); 
    } else { 
     holder = (ViewHolder) convertView.getTag(); 
    } 

    holder.conviewname.setText(user.getInitial().toUpperCase()); 
    //holder.conviewnumb.setText(""+user.getContacts().size()); 

    gridadapter= new GridAdapter(context, user.getContacts()); 

    // holder.grid.setAdapter(gridadapter); 

    holder.gridCustomView.setAdapter(gridadapter); 

    return convertView; 
} 


static class ViewHolder { 
    TextView conviewname; 
    TextView conviewnumb; 
    GridCustomView gridCustomView; 

}
