android GridView網格布局，高度問題

標籤：android   gridview寬度   網格布局   

 項目中，遇到這樣問題，

網格布局寬度自適應，但是高度設不了，文字和圖片下面有一大片空白，將高度寫死為306dp也不可以，

多方尋找，得到答案，需要在適配器中 設定layoutparams設定高度，

代碼如下

public class ServiceGridBaseAdapter extends BaseAdapter{


private Context mContext;
private List<StaffEntity> mList;
private StaffEntity entity;
 
public ServiceGridBaseAdapter() {
super();
}
 
public ServiceGridBaseAdapter(Context mContext, List<StaffEntity> mList ) {
super();
this.mContext = mContext;
this.mList = mList;
}


@Override
public int getCount() {
// TODO Auto-generated method stub
return mList.size();
}


@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return mList.get(position);
}


@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}


@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
entity = mList.get(position);
convertView = LayoutInflater.from(mContext).inflate(R.layout.item_staff_grid, null);
if(holder !=null){
holder = (ViewHolder) convertView.getTag();
} else {
holder = new ViewHolder();
holder.imageView = (ImageView)convertView.findViewById(R.id.item_service_photo);
holder.name = (TextView)convertView.findViewById(R.id.item_service_name);
holder.cell = (TextView)convertView.findViewById(R.id.item_service_cell);
   
AbsListView.LayoutParams params = new AbsListView.LayoutParams(
               android.view.ViewGroup.LayoutParams.FILL_PARENT, 306
               );
convertView.setLayoutParams(params);
    convertView.setTag(holder);
}
if(entity!=null){
holder.name.setText(entity.getName());
holder.cell.setText(entity.getTel());
// holder.imageView.setImageResource(Drawable.createFromPath(entity.getPhoto()));
}
  
return convertView;
}


class ViewHolder{

TextView name,cell;
        ImageView imageView;
}



}
