【安卓开发】Gridview网格布局+Webview

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

activity_numlock.xml

• 总体是垂直线性布局
• 里面放1个textview作为标题，1个textview作为获取密码的寄存地，1个gridview网格布局

bg_lock.xml

• 总体是垂直线性布局
• 里面一个textview文本框

numlock.java

• 锁屏界面相关制作,代码尚未优化，凑合看
• 用到 list 和 simpleadapter 适配器

public class numlock extends AppCompatActivity {

    private ListView listview;
    private ArrayList<Map<String, Object>> list;
    private SimpleAdapter simpleadapter;
    private GridView gridview;

            list.add(map);

        }
