昨天对饼状图的绘制进行了改进，对其增加了更多的消费类型，和相关的颜色。
遇到的问题：在界面显示比较模糊
今天准备做：写一个方法调用数据库的方法，获取数据库中的数据，将数据赋值给每个对应的消费类型中。
private void initView() {
        mLny = findViewById(R.id.lnyOut);
//        etCanyin = findViewById(R.id.etCanyin);

//        etCHuxing = findViewById(R.id.etChuxing);
//        etFushi = findViewById(R.id.etFushi);
//        etShenghuo = findViewById(R.id.etShenghuo);

        btnUpdate = findViewById(R.id.btnUpdate);
        btnUpdate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                uodatePieChart();
