求解setOnCheckedChangeListener在androidstudio中不出现提示代码？

Question

Answer 1

【原因】setOnCheckedChangeListener()是CheckBox的方法，不是View的方法。我说下该怎么修改，看代码:private View checkBox;//此处View应该改为CheckBox【示例】private CheckBox checkBox; @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_main);     checkBox = (CheckBox)findViewById(R.id.check_box);     checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {         @Override         public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {         }     }); }
