Binding acquisition of specific data of Item in ListView

Problem Description

• In the case of unknown number of data and network delay, there may be differences before and after the data is obtained, and the corresponding acquisition, display, and transmission [this is the key point: how to obtain the non-interfering data corresponding to this item]

problem solved

• wrong solution
  • Record with Map, then click on the corresponding item to get data from the map through position
    • Error reason: network delay, indeterminate order

• The correct solution [Android official]

  @Override
  public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
      ListView listView = (ListView) adapterView;
      实体类 entity = (实体类) listView.getItemAtPosition(i);
  
      Intent intent = new Intent();
      intent.putExtra("key", 实体类.get属性名());
      intent.setClass(FirstActivity.this, NextActivity.class);
      FirstActivity.this.startActivity(intent);
  }
