Android TimePicker 每隔5分钟

Question

我的问题是我需要每隔 5 分钟执行一次 TimePicker。

我在这里寻找的所有示例

Android - TimePicker minutes to 15

这里

How do i change the Android TimePicker minute intervals?

对我来说不起作用。

如果可以的话，我想看一个完整的工作示例。

这个代码可以，但是我不知道怎么打发这里安装的时间，也不知道怎么获取时间

import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.AttributeSet;
import android.view.View;
import android.widget.NumberPicker; 
import android.widget.TextView; 
import android.widget.TimePicker;
import java.lang.reflect.Field;
import java.util.ArrayList; 
import java.util.Calendar;
import java.util.Date;
import java.util.List;

public class MainActivity extends AppCompatActivity {

    TimePicker pickStartTime;
    TextView textwiew;
    private int TIME_PICKER_INTERVAL = 5;
    NumberPicker minutePicker;
    List<String> displayedValues;


    final Calendar cal = Calendar.getInstance();

    private int myHourS = cal.get(Calendar.HOUR_OF_DAY);
    private int myMinuteS = cal.get(Calendar.MINUTE);

    int nextMinute = 0;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textwiew =(TextView)findViewById(R.id.text1);

        pickStartTime = (TimePicker)findViewById(R.id.timePicker1);
        pickStartTime.setIs24HourView(true);

        setTimePickerInterval(pickStartTime);
    }


    private void setTimePickerInterval(TimePicker timePicker) {
        try {
            Class<?> classForid = Class.forName("com.android.internal.R$id");
            // Field timePickerField = classForid.getField("timePicker");

            Field field = classForid.getField("minute");
            minutePicker = (NumberPicker) timePicker
                    .findViewById(field.getInt(null));

            minutePicker.setMinValue(0);
            minutePicker.setMaxValue(11);
            displayedValues = new ArrayList<String>();
            for (int i = 0; i < 60; i += TIME_PICKER_INTERVAL) {
                displayedValues.add(String.format("%02d", i));
            }
            //  for (int i = 0; i < 60; i += TIME_PICKER_INTERVAL) {
            //      displayedValues.add(String.format("%02d", i));
            //  }
            minutePicker.setDisplayedValues(displayedValues
                    .toArray(new String[0]));
            minutePicker.setWrapSelectorWheel(true);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public void onClick (View v) {
      int   Minut = pickStartTime.getCurrentMinute();
        textwiew.setText(Minut);
    }


}

do not know how to get the time

使用OnTimeChangedListener

pickStartTime = (TimePicker)findViewById(R.id.timePicker1);
pickStartTime.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {

    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
        Log.d("Time", "You picked "
                + String.valueOf(view.getCurrentHour()) + ":"
                + String.valueOf(view.getCurrentMinute()));
    }

});
