Android原生控件中时间日期是分开的,但是有时我们的实际工作中可能是需要两个联动选择的,这时就需要我们自己将两个控件组合起来封装了一个工具类.

一. 创建工具类
关于控件主题以原生为主,大家可以修改themeId进行对应修改,上图就分别是主题2和主题4.绑定控件直接将TextView类型修改为对应控件对象就行.

    }
}

二. 使用:

4
// 1.创建工具类对象
final DateTimePicker dateTimePicker = new DateTimePicker();
//2.引用对象的init方法
dateTimePicker.init(context, textView);
  • context: 上下文对象
  • textview: 我们需要绑定textview对象,如果想要适应editText,那么需要将第一步工具类里面的数据类型也换成edittext.

三. 如果还需要获取事件日期选择完的事件,那么可以采用addTextChangedListener监听.

textView.addTextChangedListener(new TextWatcher() {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        
    }

    @Override
    public void afterTextChanged(Editable s) {
        
    }
});
