MaterialDatePicker 不适用于 Android [英] MaterialDatePicker not working on Android

问题描述

我想将我的项目的日期选择器更改为 Material Components for Android 提供的日期选择器，但它不起作用.

I want to change the date picker of my project to the date picker provided by the Material Components for Android, but it is not working.

这是我试过的代码:

MaterialDatePicker.Builder<Long> builder = MaterialDatePicker.Builder.datePicker();

MaterialDatePicker<Long> picker = builder.build();

picker.show(getSupportFragmentManager(), picker.toString());

Can anybody tell me what's missing?

推荐答案

问题出在 colorPrimary.

The problem was in the colorPrimary.

我的项目 colorPrimary 的默认颜色是白色"，材质日期选择器样式使用该 colorPrimary 为按钮的背景和文本着色.由于标题文本的颜色也是白色，所以看起来什么都没有.

The default color of my project to colorPrimary was "white" and the Material Date Picker style uses that colorPrimary to color the background and the text of the buttons. Since the color of the header text was also white, it appear that there was nothing there when there was everything.

我通过将样式文件导入我的项目并对我的项目中的样式进行一些调整来解决它.

I solved it by importing the styles file to my project and making some adjustments to the styles in my project.
