Android开发闹钟(详细开发步骤)

1、一、MainActivity中的代码：package .daming;import java.util.Calendar;import android.app.Activity;import android.app.AlarmManager;import android.app.AlertDialog;import android.app.PendingIntent;import android.app.TimePickerDialog;import android.content.DialogInterface;import android.content.Intent;import and

2、roid.content.SharedPreferences;import android.os.Bundle;import android.view.KeyEvent;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;import android.widget.TimePicker

3、;import android.widget.Toast;public class MainActivity extends Activity TextView setTime1; TextView setTime2; TextView setTime3; Button mButton1; Button mButton2; Button mButton3; Button mButton4; Button mButton5; Button mButton6; String time1String = null; String time2String = null; String time3Str

4、ing = null; String defalutString = 目前无设置; AlertDialog builder = null; Calendar c=Calendar.getInstance(); Override public void onCreate(Bundle savedInstanceState) super.onCreate(savedInstanceState); setContentView(R.layout.main); /取得活动的Preferences对象 SharedPreferences settings = getPreferences(Activit

5、y.MODE_PRIVATE); time1String = settings.getString(TIME1, defalutString); time2String = settings.getString(TIME2, defalutString); time3String = settings.getString(TIME3, defalutString); InitButton1(); InitButton2(); InitButton3(); InitButton4(); InitButton5(); InitButton6(); setTime1.setText(time1Str

6、ing); setTime3.setText(time2String); setTime2.setText(time3String); public void InitButton1() setTime1=(TextView) findViewById(R.id.setTime1); mButton1=(Button)findViewById(R.id.mButton1); mButton1.setOnClickListener(new View.OnClickListener() public void onClick(View v) c.setTimeInMillis(System.cur

7、rentTimeMillis(); int mHour=c.get(Calendar.HOUR_OF_DAY); int mMinute=c.get(Calendar.MINUTE); new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() public void onTimeSet(TimePicker view,int hourOfDay, int minute) c.setTimeInMillis(System.currentTimeMillis(); c.set(Calendar.

8、HOUR_OF_DAY,hourOfDay); c.set(Calendar.MINUTE,minute); c.set(Calendar.SECOND,0); c.set(Calendar.MILLISECOND,0); Intent intent = new Intent(MainActivity.this, CallAlarm.class); PendingIntent sender=PendingIntent.getBroadcast( MainActivity.this,0, intent, 0); AlarmManager am; am = (AlarmManager)getSys

9、temService(ALARM_SERVICE); am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), sender ); String tmpS=format(hourOfDay)+：+format(minute); setTime1.setText(tmpS); /SharedPreferences保存数据，并提交 SharedPreferences time1Share = getPreferences(0); SharedPreferences.Editor editor = time1Share.edit(); editor.p

10、utString(TIME1, tmpS); mit(); Toast.makeText(MainActivity.this,设置大明闹钟时间为+tmpS, Toast.LENGTH_SHORT) .show(); ,mHour,mMinute,true).show(); ); public void InitButton2() mButton2=(Button) findViewById(R.id.mButton2); mButton2.setOnClickListener(new View.OnClickListener() public void onClick(View v) Inte

11、nt intent = new Intent(MainActivity.this, CallAlarm.class); PendingIntent sender=PendingIntent.getBroadcast( MainActivity.this,0, intent, 0); AlarmManager am; am =(AlarmManager)getSystemService(ALARM_SERVICE); am.cancel(sender); Toast.makeText(MainActivity.this,大明闹钟时间删除, Toast.LENGTH_SHORT).show();

12、setTime1.setText(目前无设置); SharedPreferences time1Share = getPreferences(0); SharedPreferences.Editor editor = time1Share.edit(); editor.putString(TIME1, 目前无设置); mit(); ); public void InitButton3() setTime3=(TextView) findViewById(R.id.setTime5); mButton3=(Button)findViewById(R.id.mButton5); mButton3.

13、setOnClickListener(new View.OnClickListener() public void onClick(View v) c.setTimeInMillis(System.currentTimeMillis(); int mHour=c.get(Calendar.HOUR_OF_DAY); int mMinute=c.get(Calendar.MINUTE); new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() public void onTimeSet(Ti

14、mePicker view,int hourOfDay, int minute) c.setTimeInMillis(System.currentTimeMillis(); c.set(Calendar.HOUR_OF_DAY,hourOfDay); c.set(Calendar.MINUTE,minute); c.set(Calendar.SECOND,0); c.set(Calendar.MILLISECOND,0); Intent intent = new Intent(MainActivity.this, CallAlarm.class); PendingIntent sender=P

15、endingIntent.getBroadcast( MainActivity.this,1, intent, 0); AlarmManager am; am = (AlarmManager)getSystemService(ALARM_SERVICE); am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), sender ); String tmpS=format(hourOfDay)+：+format(minute); setTime3.setText(tmpS); /SharedPreferences保存数据，并提交 SharedPre

16、ferences time2Share = getPreferences(1); SharedPreferences.Editor editor = time2Share.edit(); editor.putString(TIME2, tmpS); mit(); Toast.makeText(MainActivity.this,设置大明闹钟时间为+tmpS, Toast.LENGTH_SHORT) .show(); ,mHour,mMinute,true).show(); ); public void InitButton4() mButton4=(Button) findViewById(R

17、.id.mButton6); mButton4.setOnClickListener(new View.OnClickListener() public void onClick(View v) Intent intent = new Intent(MainActivity.this, CallAlarm.class); PendingIntent sender=PendingIntent.getBroadcast( MainActivity.this,0, intent, 0); AlarmManager am; am =(AlarmManager)getSystemService(ALAR

18、M_SERVICE); am.cancel(sender); Toast.makeText(MainActivity.this,大明闹钟时间删除, Toast.LENGTH_SHORT).show(); setTime3.setText(目前无设置); /SharedPreferences保存数据，并提交 SharedPreferences time2Share = getPreferences(1); SharedPreferences.Editor editor = time2Share.edit(); editor.putString(TIME2, 目前无设置); mit(); ); p

19、ublic void InitButton5() setTime2=(TextView) findViewById(R.id.setTime2); LayoutInflater factory = LayoutInflater.from(this); final View setView = factory.inflate(R.layout.timeset,null); final TimePicker tPicker=(TimePicker)setView .findViewById(R.id.tPicker); tPicker.setIs24HourView(true); final Al

20、ertDialog di=new AlertDialog.Builder(MainActivity.this) .setIcon(R.drawable.clock) .setTitle(设置) .setView(setView) .setPositiveButton(确定, new DialogInterface.OnClickListener() public void onClick(DialogInterface dialog, int which) EditText ed=(EditText)setView.findViewById(R.id.mEdit); int times=Int

21、eger.parseInt(ed.getText().toString() *1000; c.setTimeInMillis(System.currentTimeMillis(); c.set(Calendar.HOUR_OF_DAY,tPicker.getCurrentHour(); c.set(Calendar.MINUTE,tPicker.getCurrentMinute(); c.set(Calendar.SECOND,0); c.set(Calendar.MILLISECOND,0); Intent intent = new Intent(MainActivity.this, Cal

22、lAlarm.class); PendingIntent sender = PendingIntent.getBroadcast( MainActivity.this,1, intent, 0); AlarmManager am; am = (AlarmManager)getSystemService(ALARM_SERVICE); am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),times,sender); String tmpS=format(tPicker.getCurrentHour()+：+ format(tP

23、icker.getCurrentMinute(); String subStr = 设置大明闹钟时间为+tmpS+ 开始，重复间隔为+times/1000+秒; setTime2.setText(设置大明闹钟时间为+tmpS+ 开始，重复间隔为+times/1000+秒); /SharedPreferences保存数据，并提交 SharedPreferences time3Share = getPreferences(2); SharedPreferences.Editor editor = time3Share.edit(); editor.putString(TIME3, subStr);

24、 mit(); Toast.makeText(MainActivity.this,设置大明闹钟为+tmpS+ 开始，重复间隔为+times/1000+秒, Toast.LENGTH_SHORT).show(); ) .setNegativeButton(取消, new DialogInterface.OnClickListener() public void onClick(DialogInterface dialog, int which) ).create(); mButton5=(Button) findViewById(R.id.mButton3); mButton5.setOnCli

25、ckListener(new View.OnClickListener() public void onClick(View v) c.setTimeInMillis(System.currentTimeMillis(); tPicker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY); tPicker.setCurrentMinute(c.get(Calendar.MINUTE); di.show(); ); public void InitButton6() mButton6=(Button) findViewById(R.id.mButton4);

26、mButton6.setOnClickListener(new View.OnClickListener() public void onClick(View v) Intent intent = new Intent(MainActivity.this, CallAlarm.class); PendingIntent sender = PendingIntent.getBroadcast( MainActivity.this,1, intent, 0); AlarmManager am; am = (AlarmManager)getSystemService(ALARM_SERVICE);

27、am.cancel(sender); Toast.makeText(MainActivity.this,闹钟时间删除, Toast.LENGTH_SHORT).show(); setTime2.setText(目前无设置); /SharedPreferences保存数据，并提交 SharedPreferences time3Share = getPreferences(2); SharedPreferences.Editor editor = time3Share.edit(); editor.putString(TIME3, 目前无设置); mit(); ); Override public

28、 boolean onKeyUp(int keyCode, KeyEvent event) if(keyCode = KeyEvent.KEYCODE_BACK) builder = new AlertDialog.Builder(MainActivity.this) .setIcon(R.drawable.clock) .setTitle(温馨提示：) .setMessage(您是否要退出大明闹钟程序!) .setPositiveButton(确定, new DialogInterface.OnClickListener() public void onClick(DialogInterfa

29、ce dialog, int whichButton) MainActivity.this.finish(); ) .setNegativeButton(取消, new DialogInterface.OnClickListener() public void onClick(DialogInterface dialog, int whichButton) builder.dismiss(); ).show(); return true; private String format(int x) String s=+x; if(s.length()=1) s=0+s; return s; 二、CallAlarm中的代码：package .daming;import android.content.Context;import android.content.Intent;import android.content.BroadcastReceiver;import android.os.Bundle;public class CallAlarm extends BroadcastReceiver Override public void onReceive(Context context, Intent intent) Intent i = new Intent(context
