今天把方法整合了一下，之前定义的对象是分开定义的，显示起来不好调用

public class zong extends AppCompatActivity {

    TextView textView;

    double zong;

    List<thing> thingList;

    Button button;

    Intent intent = new Intent();

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_zong);

        button = findViewById(R.id.button);

        webs web = new webs();

        thing2 thing2 = new thing2();

        Thread mythread = new Thread(thing2);

        mythread.start();

        try {

            mythread.join();

        } catch (InterruptedException e) {

            e.printStackTrace();

        }

        thingList = thing2.getThingList();

//        thing2 thing2 = new thing2();

        textView = findViewById(R.id.zong);

//        thingList = thing2.getThingList();

        zong=0;

        for (thing thing : thingList){

            zong = zong+Double.parseDouble(thing.getMoney());

            System.out.println(zong);

        }

        String str = String.valueOf(zong);

        textView.setText(str);

        button.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                intent.setClass(zong.this,MainActivity.class);

                startActivity(intent);

            }

        });

    }

}
