关于timepicker 设定定时闹钟的问题

[wyhzjr]

最近想做一个关于闹钟的小东西，但是不知道为什么用timepicker为什么不能设定呢？

这是主程序：

package com.example.clockdemo2;


import java.util.Calendar;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TimePicker;
import android.widget.Toast;


public class MainActivity extends Activity {
	private int my_hour;
	private int my_minute;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn=(Button)findViewById(R.id.button1);
        btn.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				Intent it=new Intent(MainActivity.this,Next.class);
				PendingIntent pi=PendingIntent.getActivity(MainActivity.this, 0, it, 0);
				TimePicker tp=(TimePicker)findViewById(R.id.timePicker1);
				my_hour=tp.getCurrentHour();
				my_minute=tp.getCurrentMinute();
				Calendar c=Calendar.getInstance();
				c.setTimeInMillis(System.currentTimeMillis());
				c.set(Calendar.HOUR, my_hour);
				c.set(Calendar.MINUTE,my_minute);
				AlarmManager a=(AlarmManager) getSystemService(Service.ALARM_SERVICE);
				a.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),pi);
				Toast.makeText(MainActivity.this, "设置成功", Toast.LENGTH_SHORT).show();
			}
		});
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

这是跳转的页面（就相当于定时闹铃提示作用，用跳转页面代替了）

package com.example.clockdemo2;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class Next extends Activity {

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

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.next, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		int id = item.getItemId();
		if (id == R.id.action_settings) {
			return true;
		}
		return super.onOptionsItemSelected(item);
	}
}

布局相当简单，就不贴了，一个button和一个timepicker 有没有前辈用timepicker获取时间做一个定时的闹钟？帮我看看哪里出错了，谢谢，分不多了。。希望大家给帮帮忙

楼主那个其实是可以的、由于模拟器时间延迟。多等1分钟就会看到效果了。不过建议把这个 c.set(Calendar.HOUR, my_hour); 改为c.set(Calendar.HOUR_OF_DAY, my_hour); 这是我自己写的代码: package com.example.vince; import java.util.Calendar; import android.app.Activity; import android.app.AlarmManager; import android.app.PendingIntent; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.widget.TimePicker; import android.widget.Toast; public class MainActivity extends Activity { private TimePicker timePicker; private Calendar c; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); c=Calendar.getInstance(); c.setTimeInMillis(System.currentTimeMillis()); timePicker=(TimePicker) findViewById(R.id.timePicker); timePicker.setIs24HourView(true); /*//由于timePicker会自动显示系统默认的当前时间。以下2个可不写 timePicker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY));//设置当前的小时 timePicker.setCurrentMinute(c.get(Calendar.MINUTE));//设置当前的分钟 */ } public void settingAlarm(View v){ Intent intent=new Intent(this,AlarmActivity.class); PendingIntent pendingIntent=PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); AlarmManager alarmManager=(AlarmManager) getSystemService(ALARM_SERVICE); c.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour()); c.set(Calendar.MINUTE, timePicker.getCurrentMinute()); alarmManager.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent); Toast.makeText(this, "设置成功", 2000).show(); } } 跳转页面的代码: import android.app.Activity; import android.os.Bundle; public class AlarmActivity extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.alarm_layout); } }
