推荐答案

您可以动态地生成一个GridView。

You can generate a GridView dynamically.

GridView控件将包含的ImageView和TextView中的按照您的需要。你将不得不使用自定义的适配器。在它的 getView 法，填充的ImageView和TextView的。

GridView would contain of ImageView and TextView as per your need. You will have to use your custom adapter. In it's getView method, populate the ImageView and TextView.

示例：

GridView控件item.xml：

GridView item.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/imgItem"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/txtItem"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:fontFamily="trebuchet"
        android:textColor="@android:color/black"
        android:textSize="15sp"
        android:textStyle="bold" />

</LinearLayout>

Java的code：

Java code:

一个POJO类项目：

public class Item
{
    String title;
    Drawable image;
    //getter setter
}

适配器类：

//getView method in your adapter class

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    View itemView = convertView;
    ViewHolder holder = null;

    if (itemView == null)
    {
        final LayoutInflater layoutInflater =
            (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        itemView = layoutInflater.inflate(resourceId, parent, false);

        holder = new ViewHolder();
        holder.imgItem = (ImageView) itemView.findViewById(R.id.imgItem);
        holder.txtItem = (TextView) itemView.findViewById(R.id.txtItem);
        itemView.setTag(holder);
    }
    else
    {
        holder = (ViewHolder) itemView.getTag();
    }

    Item item = getItem(position);
    holder.imgItem.setImageDrawable(item.getImage());
    holder.txtItem.setText(item.getTitle());

    return itemView;
}

现在在你的Activity类中添加适配器的数据，然后设置适配器的GridView。

Now add adapter data in your Activity class and then set that adapter to GridView.
