今日总结0420

今天是周四，上午在APP中增加了商品列表的展示，代码如下：

public class BuhuoActivity extends AppCompatActivity implements View.OnClickListener {

    private ListView mSimpleList;
    private SimpleAdapter mSimpleAdapter;
    private List<Map<String, Object>> mList;
    private int[] imgs = {
            R.drawable.img,
            R.drawable.img1,
            R.drawable.img2,
            R.drawable.img3,
    };
    int number = new Random().nextInt(10) + 1;
    String[] eqs = {"是", "否"};

    public String eqq(int t) {
        t = number;
        if (t <= 4) {
            return eqs[0];
        } else {
            return eqs[1];
        }
    }

    private Button btnmap, btntoadd;

    @SuppressLint("MissingInflatedId")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_buhuo);
        btnmap = findViewById(R.id.btn_map);
        btntoadd = findViewById(R.id.btn_ToAdd);
        btnmap.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                intent.setClass(BuhuoActivity.this, MapActivity.class);
                startActivity(intent);
            }

        });

        btntoadd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                intent.setClass(BuhuoActivity.this, ShenqingActivity.class);
                startActivity(intent);
            }

        });

        mSimpleList = findViewById(R.id.lv1);
        mList = new ArrayList<>();

        for (int i = 1; i < 12; i++) {
            Map<String, Object> map = new HashMap();
            map.put("img", imgs[i % imgs.length]);
            map.put("title", "商品" + i);
            map.put("content1", "当前剩余：" + number);
            map.put("content2", "是否需要补货：" + eqq(number));
            mList.add(map);
        }

        mSimpleAdapter = new SimpleAdapter(this,
                mList,
                R.layout.list_item_layout,
                new String[]{"img", "title", "content1", "content2"},
                new int[]{R.id.iv_img, R.id.tv_title, R.id.tv_content1, R.id.tv_content2}
        );
        mSimpleList.setAdapter(mSimpleAdapter);
    }
遇到的问题：本来想写一个柱状图，但是导入的接口文件中的一个方法参数只有可读权限，没办法依照此项目进行修改。
明天要干什么：在原本的地图接口上接入导航接口。
