checkbox 可以切换页面（Activity）：

private CheckBox checkBox;
CheckBox checkBox = findViewById(R.id.checkbox);
        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    // 当复选框被选中时，切换到另一个Activity或更改布局
                    Intent intent = new Intent(MainActivity3.this, AnotherMainActivity.class);
                    startActivity(intent);
                } else {
                    // 当复选框未被选中时，做相应的操作
                    finish();
                }
            }
        });
