如何围绕gridview行和列创建边框

Question

我使用了一个带有自定义适配器的gridview和用于行的textViews。以下是代码：

ScheduleListActivity.java

    public class ScheduleListActivity extends android.app.Activity 
    {
        GridView gridView;
        ScheduleModel  aSchedulObj;
        ArrayList<ScheduleModel> schedul_arr;
        GetCityFromAsync cityAsync;
        AdapterScheduleList myAdapter;

        @Override
        public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_view_schedule);
           schedul_arr = new ArrayList<ScheduleModel>();
           gridView = (GridView) findViewById(R.id.lst_all_schedule);

            cityAsync =new GetCityFromAsync();
            cityAsync.execute();
        }

        private class GetCityFromAsync extends AsyncTask<Void, Void, String>
        {
            Context context;

            @Override
            protected void onPreExecute() 
                { super.onPreExecute();     }

            @Override
            protected String doInBackground(Void... arg0) 
                { return null; }

            @Override
            protected void onPostExecute(String result) 
              {
                super.onPostExecute(result);

                    try {
                        aSchedulObj = new ScheduleModel("Shaon", "23-Sep-2015", "12:58", "1:00", "92.800", "101.02", "Mirpur, kazipara");
                        schedul_arr.add(aSchedulObj);

                        aSchedulObj = new ScheduleModel("aaaa", "bbb", "12:58", "1:00", "92.800", "101.02", "rokeya sharani, kazipara");
                        schedul_arr.add(aSchedulObj);

                        aSchedulObj = new ScheduleModel("xxx", "yyy", "1:58", "2:00", "55.00", "60.55", "panthapath, kalabagan");
                        schedul_arr.add(aSchedulObj);

                            myAdapter = new AdapterScheduleList(getApplicationContext(), schedul_arr);
                            gridView.setAdapter(myAdapter);
                        }
                     catch (Exception e) {
                        e.printStackTrace();    }
            }
        }
    }

ScheduleListActivity的

gridview适配器

    public class AdapterScheduleList extends BaseAdapter {

        Context _adapterContext;
        ArrayList<ScheduleModel> sch_arr;

        public AdapterScheduleList(Context context,
                ArrayList<ScheduleModel> scheduls) {
            _adapterContext = context;
            this.sch_arr = scheduls;
        }

        public void updateList() {  notifyDataSetChanged(); }

        @Override
        public int getCount() {     return sch_arr.size();  }

        @Override
        public ScheduleModel getItem(int position) { return sch_arr.get(position);  }

        @Override
        public long getItemId(int position) {return Long.valueOf(sch_arr.get(position).getScheduleID());    }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) _adapterContext
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View rowView = inflater.inflate(R.layout.listitem_schedule, parent,false);

            final ScheduleModel _aSchdl = (ScheduleModel) getItem(position);

            TextView txtVwName = (TextView) rowView.findViewById(R.id.grid_item_name);
            txtVwName.setText(_aSchdl.getClientName());

            TextView txtVwDate = (TextView) rowView.findViewById(R.id.grid_item_date);
            txtVwDate.setText(String.valueOf(_aSchdl.getScheduleDate()));

            TextView txtVwStartTime = (TextView) rowView.findViewById(R.id.grid_item_label_starttime);
            txtVwStartTime.setText(String.valueOf(_aSchdl.getScheduleStartTime()));

            TextView txtVwEndTIme = (TextView) rowView.findViewById(R.id.grid_item_endTime);
            txtVwEndTIme.setText(String.valueOf(_aSchdl.getScheduleEndTime()));

            TextView txtVwAddress = (TextView) rowView.findViewById(R.id.grid_item_address);
            txtVwAddress.setText(String.valueOf(_aSchdl.getScheduleAddress()));

            return rowView;
        }

    }

行项目布局 - listitem_schedule.xml

现在我需要的是行和列的边框。怎么可能？由于我尝试了几种解决方案而失败了，所以最后不得不使用视图作为下划线边框。

请帮帮我： - ）

Answer 1

为您的gridview提供一个边距，使其小于其容器。

然后“边框”将成为容器本身，显示其背景颜色/图像。

这就是你如何围绕gridview制作边框

希望它有所帮助。

Answer 2

在drawable文件夹中创建以下可绘制资源border.xml，并将其设置为listitem_schedule.xml

的背景

<强> border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
   <!-- use this for transparent -->
   <!-- <solid android:color="#00000000" /> -->
   <!-- use this for a background colour -->
   <solid android:color="#FFF" />
   <stroke android:width="2dip" android:color="#FF0000" />
</shape>

并在您的listitem_schedule.xml aprent LinearLayout设置背景中，如下所示 android:background="@drawable/border"
