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);
}
});
}
}
