Question

如图所示，使用gridview

生成界面

正如你所看到的，他在队伍中有这些跳跃。

Answer 1

试试这个..

 <?xml version="1.0" encoding="utf-8"?>
 <GridView xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/grid"
   android:layout_width="fill_parent"
   android:layout_height="fill_parent"
   android:numColumns="2"
   android:verticalSpacing="10dp"
   android:horizontalSpacing="10dp"
   android:scrollbarStyle="outsideOverlay"
   android:verticalScrollbarPosition="right"
   android:scrollbars="vertical">
</GridView>

Answer 2

将空数据添加到列表中

ArrayList<Data> list=new ArrayList<Data>
list.add(new Data(G13));
list.add(new Data(G23));
list.add(new Data(0);//set id=0
list.add(new Data(G43));

在适配器getView（）

中

public View getView(int position, View convertView, ViewGroup parent) {  
    if(list.get(position).getId().equals("0")){//empty data
        view.setVisibility(View.INVISIBLE)
    }else{
        view.setVisibility(View.VISIBLE)
    }
}

Answer 3

试试我的解决方案，

以编程方式在gridview布局行和列之间显示笔划

在网格视图项之间显示边框，将GridView分开项目，以便每个项目单独查看。在本教程中我们正在创建自定义字符串数组并设置该字符串数组使用数组适配器类进入网格视图。现在我们是动态的为每个字符串元素创建textview并设置该元素里面的网格视图一个接一个。所以这是完整的一步一步如何显示GridView项之间的分隔符/边框的教程在Android中。

MainActivity.java文件的代码

       public class MainActivity extends Activity {

         GridView gridView;
         List<String> ItemsList;
         String[] itemsName = new String[]{
         "ONE", "TWO", "THREE", "FOUR", "FIVE", "SIX", "SEVEN", "EIGHT","NINE"};
         @Override
         protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         gridView = (GridView)findViewById(R.id.gridView1);
         ItemsList = new ArrayList<String>(Arrays.asList(itemsName));
         gridView.setAdapter(new TextAdapter(this));
         }

         private class TextAdapter extends BaseAdapter
         {
         Context context;
         public TextAdapter(Context context) 
         {
         this.context = context;
         }

         @Override
         public int getCount() {

         return itemsName.length;
         }

         @Override
         public Object getItem(int position) {
         // TODO Auto-generated method stub
         return itemsName[position];
         }

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

         @Override
         public View getView(int position, View convertView, ViewGroup parent) {
         // TODO Auto-generated method stub
         TextView text = new TextView(this.context);
         text.setText(itemsName[position]);
         text.setGravity(Gravity.CENTER);
         text.setBackgroundColor(Color.parseColor("#fbdcbb"));
         text.setLayoutParams(new GridView.LayoutParams(144, 144));
         text.setBackgroundResource(R.layout.grid_items_border);

         return text;
          }
         }
        }

</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
