带有文本和图像的android网格视图

Question

我想创建一个总共有7列的网格视图。网格中的第一行是文本，它是动态的，并且连续的行包含图像，这些图像也是动态的。第一，我尝试了单独的动态图像，并成功，但在添加文本视图后，我收到错误。

我对网格视图适配器是这样

private Context mContext; 
private int[] colors = new int[] { Color.WHITE, 0x30aaaaaa }; 
private int[] dotColors = new int[7]; 
private int[] sta= new int[100]; 
private TasksDataSource datasource; 
private int con=1000; 
TextView textview1; 
public Integer[] mThumbIds = new Integer[con]; 
String[] dday = {"S","M","T","W","T","F","S"}; 
int[] day7; 

public ImageAdapter(Context context, int[] content,int[] content2){ 
    sta = content; 
    day7=content2; 
    datasource = new TasksDataSource(context); //here 
    datasource.open(); 
    mContext=context; 
}s 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    int[] st = new int[sta.length]; 
    int ii=0,jj=0; 
    View myView = null; 
    if(convertView==null) { 
     LayoutInflater li = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     myView = li.inflate(R.layout.gridmenu, null); 
    }else{ 
     myView = convertView; 
    } 

    TextView tv = (TextView) myView.findViewById(R.id.grid_item_text); 
    if(position<7) { 
     tv.setText(dday[position]); 
     tv.setTextColor(day7[position]); 
    } 
    else { 
     ImageView imageView =(ImageView) myView.findViewById(R.id.grid_item_image); 
     imageView.setImageResource(sta[position]); 
     imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); 
    } 

    return myView; 
} 

我的网格布局是这样的

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/GridItem" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:gravity="center_horizontal"> 

    <TextView android:id="@+id/grid_item_text" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:gravity="center_horizontal" 
     android:layout_centerHorizontal="true"> 
    </TextView> 

    <ImageView android:id="@+id/grid_item_image" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content"> 
    </ImageView> 

</RelativeLayout> 

我得到的问题是图像不适合。他们失去了。处理职位时我的代码是否正确？

创建文本图的布局和膨胀是与使用该适配器...

public static class ImageAdapter extends BaseAdapter { 
       Context MyContext; 
       List<Buttons> list; 
       private LayoutInflater mInflater; 
       int pos; 

       public ImageAdapter(Context _MyContext, List<Buttons> _list) { 
        MyContext = _MyContext; 
        mInflater = LayoutInflater.from(_MyContext); 
        list = _list; 
       } 

       public int getCount() { 
        return list.size(); 
       } 

       public View getView(int position, View convertView, ViewGroup parent) { 
        ViewHolder holder; 

        if (convertView == null) { 
         convertView = mInflater.inflate(R.layout.grid_item, null); 
         holder = new ViewHolder(); 

         holder.text= (Textview) convertView 
           .findViewById(R.id.grid_item_text); 
         holder.image = (ImageView) convertView.findViewById(R.id.grid_item_image); 
         holder.image.setImageResource(list.get(position).getIconid()); 
         holder.text.setText(list.get(position).getText); 
        } else { 
         convertView = mInflater.inflate(R.layout.grid_item, null); 
         holder = new ViewHolder(); 
         holder.text= (Textview) convertView 
           .findViewById(R.id.grid_item_text); 
         holder.image = (ImageView) convertView 
           .findViewById(R.id.grid_item_image); 
         holder.image.setImageResource(list.get(position).getIconid()); 
holder.text.setText(list.get(position).getText); 
        } 
        convertView.setBackgroundDrawable(null); 
        return convertView; 
       } 

       public Object getItem(int arg0) { 
        return arg0; 
       } 

       public long getItemId(int arg0) { 
        return arg0; 
       } 

       static class ViewHolder { 
        ImageView image; 
        Textview text; 
       } 
      }
