Android:关注 TimePicker 元素

Question

如何将焦点放在时间选择器元素上？我正在开发电视应用程序，因此需要远程操作。所以我需要关注每个元素。TimePicker 有 3 个元素 - 小时列、分钟列和 AM/PM 列。

那么我如何才能专注于这 3 列中的每一列？

谢谢

你可以获取TimePicker的每一个NumberPicker，然后做任何你想做的修改，请求焦点等等。

NumberPicker hourPicker = (NumberPicker) mTimePicker.findViewById(Resources.getSystem().getIdentifier("hour",
     "id", "android"));

NumberPicker minutePicker = (NumberPicker) mTimePicker.findViewById(Resources.getSystem().getIdentifier("minute",
     "id", "android"));

NumberPicker amPmPicker = (NumberPicker) mTimePicker.findViewById(Resources.getSystem().getIdentifier("amPm",
     "id", "android"));

// this is a number picker modified and there is one for each NumerPicker above
View numberPickerModified = (View) mTimePicker.findViewById(Resources.getSystem().getIdentifier("numberpicker_input",
     "id", "android"));
