android闹铃简单实现
1.闹铃activity
packagecom.example.myalarm;
importjava.util.Calendar;
importjava.util.Date;
importjava.util.Locale;
importandroid.media.RingtoneManager;
importandroid.net.Uri;
importandroid.os.Bundle;
importandroid.provider.MediaStore;
importandroid.app.Activity;
importandroid.app.AlarmManager;
importandroid.app.PendingIntent;
importandroid.app.TimePickerDialog;
importandroid.app.TimePickerDialog.OnTimeSetListener;
importandroid.content.Intent;
importandroid.database.Cursor;
importandroid.util.Log;
importandroid.view.Menu;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.widget.Button;
importandroid.widget.TimePicker;
publicclassAlarmActivityextendsActivity{
privatestaticfinalStringTAG="AlarmActivity";
AlarmManageralarmManager;
Calendarcalendar=Calendar.getInstance(Locale.CHINESE);
ButtonsetTime;
ButtonsetRing;
ButtonsetOver;
UriringUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
@Override
protectedvoidonCreate(BundlesavedInstanceState){
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();
}
privatevoidsetTimeAndRing(){
setTime.setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewview){
setTime();
}
});
setRing.setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewview){
setRingtone();
}
});
setOver.setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewview){
setAlarm(calendar);
}
});
}
//启动闹玲，设置闹玲
privatevoidsetAlarm(Calendarcalendar){
Intentintent=newIntent();
intent.setClass(this,AlarmBroadcastReceiver.class);
intent.putExtra("msg","Getup!Getup!");
intent.putExtra("ringURI",ringUri.toString());
Log.d(TAG,ringUri.toString());
PendingIntentpendingIntent=PendingIntent.getBroadcast(this,0,intent,0);
alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),pendingIntent);
}
//设置时间
privatevoidsetTime(){
Datedate=newDate();
calendar.setTime(date);
inthour=calendar.get(Calendar.HOUR);
intminute=calendar.get(Calendar.MINUTE);
newTimePickerDialog(this,newOnTimeSetListener(){
@Override
publicvoidonTimeSet(TimePickertimePicker,inthour,intminute){
calendar.set(Calendar.HOUR,hour);
calendar.set(Calendar.MINUTE,minute);
}
},hour,minute,true).show();
}
//设置闹玲铃声
privatevoidsetRingtone(){
Intentintent=newIntent();
intent.setAction(RingtoneManager.ACTION_RINGTONE_PICKER);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT,false);
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE,"设置闹玲铃声");
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE,RingtoneManager.TYPE_ALL);
UripickedUri=RingtoneManager.getActualDefaultRingtoneUri(this,RingtoneManager.TYPE_ALARM);
if(pickedUri!=null){
intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,pickedUri);
ringUri=pickedUri;
}
startActivityForResult(intent,1);
}
@Override
protectedvoidonActivityResult(intrequestCode,intresultCode,Intentdata){
super.onActivityResult(requestCode,resultCode,data);
if(resultCode!=RESULT_OK){
return;
}
switch(requestCode){
case1:
//获取选中的铃声的URI
UripickedURI=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;
}
}
privatevoidgetName(inttype){
UripickedUri=RingtoneManager.getActualDefaultRingtoneUri(this,type);
Log.i(TAG,pickedUri.toString());
Cursorcursor=this.getContentResolver().query(pickedUri,newString[]{MediaStore.Audio.Media.TITLE},null,null,null);
if(cursor!=null){
if(cursor.moveToFirst()){
Stringring_name=cursor.getString(0);
Log.i(TAG,ring_name);
String[]c=cursor.getColumnNames();
for(Stringstring:c){
Log.i(TAG,string);
}
}
cursor.close();
}
}
@Override
publicbooleanonCreateOptionsMenu(Menumenu){
getMenuInflater().inflate(R.menu.alarm,menu);
returntrue;
}
}
2，布局文件
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Buttonandroid:id="@+id/setTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="设置时间"/>
<Buttonandroid:id="@+id/setRing"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/setTime"
android:text="设置铃声"/>
<Buttonandroid:id="@+id/setOver"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/setRing"
android:text="设置完成"/>
</RelativeLayout>
3.广播接收闹铃信息：
packagecom.example.myalarm;
importjava.io.IOException;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.media.MediaPlayer;
importandroid.net.Uri;
importandroid.util.Log;
importandroid.widget.Toast;
publicclassAlarmBroadcastReceiverextendsBroadcastReceiver{
UriringUri;
@Override
publicvoidonReceive(Contextcontext,Intentintent){
Stringmsg=intent.getStringExtra("msg");
Toast.makeText(context,msg,Toast.LENGTH_SHORT).show();
MediaPlayermp=newMediaPlayer();
Stringuri=intent.getStringExtra("ringURI");
if(uri!=null){
ringUri=Uri.parse(uri);
Log.d("AlarmActivity",ringUri.toString());
}
try{
mp.setDataSource(context,ringUri);
mp.prepare();
}catch(IllegalArgumentExceptione){
e.printStackTrace();
}catch(SecurityExceptione){
e.printStackTrace();
}catch(IllegalStateExceptione){
e.printStackTrace();
}catch(IOExceptione){
e.printStackTrace();
}
mp.start();
}
}
4.在manifest文件中注册广播
<receiverandroid:name="com.example.myalarm.AlarmBroadcastReceiver"></receiver>
以上代码就是实现Android闹钟的全部代码了，希望大家能够喜欢。
