我的做法:
- 在dependencies中添加
implementation 'com.google.android.material:material:1.1.0'
- 将应用程序主题的父级设置为
Theme.MaterialComponents.Light.Bridge
<style name="AppTheme" parent="Theme.MaterialComponents.Light.Bridge">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
- 尝试在片段中显示日期选择器。
MaterialDatePicker.Builder<Pair<Long, Long>> builder = MaterialDatePicker.Builder.dateRangePicker();
Calendar now = Calendar.getInstance();
now.set(Calendar.YEAR, 2020);
now.set(Calendar.MONTH, 1);
now.set(Calendar.DAY_OF_MONTH, 10);
long first = now.getTimeInMillis();
now.set(Calendar.YEAR, 2020);
now.set(Calendar.MONTH, 5);
now.set(Calendar.DAY_OF_MONTH, 20);
long last = now.getTimeInMillis();
builder.setSelection(new Pair<>(first, last));
MaterialDatePicker<Pair<Long, Long>> picker = builder.build();
picker.show(fragmentActivity.getSupportFragmentManager(), "RangePicker");
当我运行代码时,出现了这个错误
java.lang.IllegalArgumentException: com.google.android.material.datepicker.MaterialDatePicker
requires a value for the com.example:attr/materialCalendarFullscreenTheme attribute to be set
in your app theme. You can either set the attribute in your theme or update your theme to
inherit from Theme.MaterialComponents (or a descendant).
Theme.MaterialComponents.*
主题,它应该会自动包含所需的主题和样式。 - EdricmaterialCalendarStyle
应该是 attr,而不是 item。 - IgorGanapolsky
