一：效果图

六步即可完成GridView不同背景色，并且每个单元格可点击

• GridView布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#EAEBEB">

    <GridView
        android:id="@+id/gridview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#EAEBEB"
        android:numColumns="5" />
</RelativeLayout>

• GridView Item布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll_item"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/tv_item"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_gravity="center"
        android:layout_margin="1px"
        android:background="#95c5ef"
        android:gravity="center"
        android:singleLine="true" />
</LinearLayout>

• 添加表头

    public void addHeader() {
        String items[] = {"", "迟到", "早退", "缺席", "请假"};
        for (String strText : items) {
            //booleans列表记录状态，改变表格颜色
            booleans.add(0);
            list.add(strText);
        }
        adapter.notifyDataSetChanged(); //更新数据
    }

• 添加数据

  public void addData() {

        String titles[] = {"早操", "早自习", "上课", "晚自习", "晚寝", "活动点到"};
        for (int i = 0; i < 6; i++) {
            for (int j = 0; j < 5; j++) {
                if (j == 0) {
                    list.add(titles[i]);
                } else {
                    list.add("i=" + i + "j=" + j);
                }
                if (i % 2 == 0) {
                    booleans.add(1);

                } else {
                    booleans.add(2);
                }
            }
        }
        adapter.notifyDataSetChanged(); //更新数据
    }

• 为GridView设置适配器

@Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder = null;
            if (convertView == null) {
                convertView = View.inflate(MainActivity.this, R.layout.grid_item, null);
                holder = new ViewHolder();
                convertView.setTag(holder);
                holder.tv_item = (TextView) convertView.findViewById(R.id.tv_item);
                holder.ll_item = (LinearLayout) convertView.findViewById(R.id.ll_item);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }

            holder.tv_item.setText(list.get(position));

            if (booleans.get(position) == 0) {
                //表头颜色
                holder.tv_item.setBackgroundColor(Color.parseColor("#95c5ef"));
                holder.ll_item.setBackgroundColor(Color.WHITE);
            } else if (booleans.get(position) == 1) {
                //奇数行颜色
                holder.tv_item.setBackgroundColor(Color.parseColor("#EAEBEB"));
                holder.ll_item.setBackgroundColor(Color.parseColor("#dadada"));
            } else {
                //偶数行颜色
                holder.tv_item.setBackgroundColor(Color.parseColor("#FFFFFF"));
                holder.ll_item.setBackgroundColor(Color.parseColor("#dadada"));
            }
            return convertView;
        }

        class ViewHolder {
            private TextView tv_item;
            private LinearLayout ll_item;
        }

• GridView设置item点击事件

    //表格点击事件
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Toast.makeText(MainActivity.this, list.get(position), Toast.LENGTH_SHORT).show();
    }
