推荐答案

如果你需要一个简单的解决方案，您可以添加边框在绘制每个网格项自定义视图来绘制。

If you need a simpler solution, you could add the border to be drawn in your custom views drawn for each grid item.

举例code：

public class ExampleAdapter extends BaseAdapter {
    private Activity activity;
    private LayoutInflater inflater;
    public ExampleAdapter(Activity activity)
    {
        this.activity = activity;
        this.inflater = activity.getLayoutInflater();
    }

    @Override
    public View getView(int pos, View convertView, ViewgGroup parent) {
        ViewHolder holder = null;
        if(converView == null) {
            convertView = inflater.inflate(R.layout.view_example);      
            holder = new ViewHolder();
            //Set holder ids here
            holder.title = convertView.findViewById(R.id.title)
        }
        //Populate your holder here with data here.
        holder.title.setText("My Awesome Title!");
        convertView.setTag(holder);
        return convertView;
    } 
}

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="@dimen/grid_item_width"
    android:layout_height="@dimen/grid_item_height"
    android:background="@color/grid_border"
    android:padding="1dip" >
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/white" >
        <TextView android:id="@+id/title" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content">
    </FrameLayout>
</FrameLayout>
