本文給大家分享的是一段簡單的實(shí)現(xiàn)Android系統(tǒng)的鬧鈴的代碼，非常實(shí)用，想做Android開發(fā)的小伙伴們可以參考下。

1.鬧鈴activity

package com.example.myalarm;

import java.util.Calendar;

import java.util.Date;

import java.util.Locale;

import android.media.RingtoneManager;

import android.net.Uri;

import android.os.Bundle;

import android.provider.MediaStore;

import android.app.Activity;

import android.app.AlarmManager;

import android.app.PendingIntent;

import android.app.TimePickerDialog;

import android.app.TimePickerDialog.OnTimeSetListener;

import android.content.Intent;

import android.database.Cursor;

import android.util.Log;

import android.view.Menu;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.TimePicker;

public class AlarmActivity extends Activity {

    private static final String TAG = "AlarmActivity";

    AlarmManager alarmManager;

    Calendar calendar = Calendar.getInstance(Locale.CHINESE);

    Button setTime;

    Button setRing;

    Button setOver;

    Uri ringUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_alarm);

        alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        setTime = (Button) findViewById(R.id.setTime);

        setRing = (Button) findViewById(R.id.setRing);

        setOver = (Button) findViewById(R.id.setOver);

        //setTime();

        //setRingtone();

        setTimeAndRing();

    }

    private void setTimeAndRing(){

        setTime.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View view) {

                setTime();

            }

        });

        setRing.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View view) {

                setRingtone();

            }

        });

        setOver.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View view) {

                setAlarm(calendar);

            }

        });

    }

    //啟動鬧玲，設(shè)置鬧玲

    private void setAlarm(Calendar calendar){

        Intent intent = new Intent();

        intent.setClass(this, AlarmBroadcastReceiver.class);

        intent.putExtra("msg", "Get up!Get up!");

        intent.putExtra("ringURI", ringUri.toString());

        Log.d(TAG, ringUri.toString());

        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

        alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(), pendingIntent);

    }

    //設(shè)置時間

    private void setTime(){

        Date date = new Date();

        calendar.setTime(date);

        int hour = calendar.get(Calendar.HOUR);

        int minute = calendar.get(Calendar.MINUTE);

        new TimePickerDialog(this, new OnTimeSetListener() {

            @Override

            public void onTimeSet(TimePicker timePicker, int hour, int minute) {

                calendar.set(Calendar.HOUR,hour);

                calendar.set(Calendar.MINUTE,minute);

            }

        }, hour, minute, true).show();

    }

    //設(shè)置鬧玲鈴聲

    private void setRingtone(){

        Intent intent = new Intent();

        intent.setAction(RingtoneManager.ACTION_RINGTONE_PICKER);

        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, false);

        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "設(shè)置鬧玲鈴聲");

        intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_ALL);

        Uri pickedUri = RingtoneManager.getActualDefaultRingtoneUri(this,RingtoneManager.TYPE_ALARM);

        if (pickedUri!=null) {

            intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,pickedUri);

            ringUri = pickedUri;

        }

        startActivityForResult(intent, 1);

    }

    @Override

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);

        if (resultCode!=RESULT_OK) {

            return;

        }

        switch (requestCode) {

        case 1:

            //獲取選中的鈴聲的URI

            Uri pickedURI = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);

            Log.i(TAG,pickedURI.toString());

            RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, pickedURI);

            getName(RingtoneManager.TYPE_ALARM);

            break;

        default:

            break;

        }

    }

    private void getName(int type){

        Uri pickedUri = RingtoneManager.getActualDefaultRingtoneUri(this, type);

        Log.i(TAG,pickedUri.toString());

        Cursor cursor = this.getContentResolver().query(pickedUri, new String[]{MediaStore.Audio.Media.TITLE}, null, null, null);

        if (cursor!=null) {

            if (cursor.moveToFirst()) {

                String ring_name = cursor.getString(0);

                Log.i(TAG,ring_name);

                String[] c = cursor.getColumnNames();

                for (String string : c) {

                    Log.i(TAG,string);

                }

            }

            cursor.close();

        }

    }

    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.alarm, menu);

        return true;

    }

}

2，布局文件

復(fù)制代碼代碼如下:

3.廣播接收鬧鈴信息：

復(fù)制代碼代碼如下:

package com.example.myalarm;

import java.io.IOException;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.media.MediaPlayer;

import android.net.Uri;

import android.util.Log;

import android.widget.Toast;

public class AlarmBroadcastReceiver extends BroadcastReceiver {

    Uri ringUri;

    @Override

    public void onReceive(Context context, Intent intent) {

        String msg = intent.getStringExtra("msg");

        Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();

        MediaPlayer mp = new MediaPlayer();

        String uri = intent.getStringExtra("ringURI");

        if (uri!=null) {

            ringUri = Uri.parse(uri);

            Log.d("AlarmActivity", ringUri.toString());

        }

        try {

            mp.setDataSource(context, ringUri);

            mp.prepare();

        } catch (IllegalArgumentException e) {

            e.printStackTrace();

        } catch (SecurityException e) {

            e.printStackTrace();

        } catch (IllegalStateException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

        mp.start();

    }

}
