Question

在我的项目中，我使用 TimePicker 对话框 来允许用户 select 时间。但我不希望他们 select 分钟。所以，我只想 禁用（或隐藏）分钟 selection。那么，如何做到这一点？

Answer 1

简短的回答是你不能。您必须创建自己的自定义对话框。

长话短说，您可能可以，但不应该。您可以找到视图的 ID 并禁用或隐藏它，但每个版本和制造商可能为此对话框使用不同的 ID，因此您将运行遇到许多问题和错误。

Answer 2

我使用 Material TimePickerDialog Library.

解决了我的问题

我的解决方案：

public class home extends AppCompatActivity implements TimePickerDialog.OnTimeSetListener, ... {
    ...
    private EditText time;
    private TimePickerDialog timePickerDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        ...

        timePickerDialog = TimePickerDialog.newInstance(home.this, new Date().getHours(), new Date().getMinutes(), false);
        timePickerDialog.enableMinutes(false);

        time = (EditText) findViewById(R.id.time);
        time.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                timePickerDialog.show(getFragmentManager(), "TimePickerDialog");
            }
        });
    }

    @Override
    public void onTimeSet(TimePickerDialog view, int hourOfDay, int minute, int second) {
        String form;
        if (hourOfDay > 12) {
            hourOfDay = hourOfDay - 12;
            form = "PM";
        } else {
            if (hourOfDay == 0) {
                hourOfDay = 12;
            }
            form = "AM";
        }
        time.setText(String.valueOf(hourOfDay) + " " + form);
    }

    ...
}

没有库和简单的时间选择器

time_picker.setIs24HourView(true)
time_picker.currentMinute = 0
time_picker.currentHour = 0
time_picker.findViewById<View>(Resources.getSystem()
       .getIdentifier("hour", "id", "android"))
       .visibility = View.GONE

将 id 标识符更改为您需要隐藏或显示的内容

Answer 4

这解决了我的本地时间选择器组件问题
1. 禁用分钟选择
2.隐藏时间分隔符
3. 当用户选择小时

时禁用从小时到分钟的转换

代码在 kotlin 中。

// Disbale time picker minutes
time_picker.findViewById<View>(Resources.getSystem()
            .getIdentifier("minutes", "id", "android"))
            .visibility = View.GONE
// Disbale time seperator
time_picker.findViewById<View>(Resources.getSystem()
            .getIdentifier("separator", "id", "android"))
            .visibility = View.INVISIBLE

val delegateField = time_picker.javaClass.getDeclaredField("mDelegate")
delegateField.isAccessible = true;
val autoAdvance = delegateField.get(time_picker)
val autoAdvanceField = autoAdvance.javaClass.getDeclaredField("mAllowAutoAdvance")

autoAdvanceField.isAccessible = true
autoAdvanceField.set(autoAdvance, false)

输出：

Android - 在 TimePicker 对话框中禁用（或隐藏）分钟选择
