Привет. Я хочу установить уведомление о тревоге, когда экран мобильного телефона выключен. Мой код "
package com.my.timeout;
import java.util.Calendar;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.widget.Toast;
public class ScreenON_OFF_ACTIVITY extends Activity
{
AlarmManager am;
private static final int REQUEST_CODE = 0;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
onCreate1();
}
public void onCreate1() {
// initialize receiver
System.out.println("onCreate1 ");
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new ScreenReceiver();
registerReceiver(mReceiver, filter);
System.out.println("onCreate ");
}
@Override
protected void onPause() {
// when the screen is about to turn off
if (ScreenReceiver.screenOff) {
// this is the case when onPause() is called by the system due to a screen state change
System.out.println("SCREEN TURNED OFF");
} else {
// this is when onPause() is called when the screen state has not changed
System.out.println("this is when onPause() is called when the screen state has not changed ");
display_alarm();
}
super.onPause();
}
@Override
protected void onResume() {
// only when screen turns on
if (!ScreenReceiver.screenOff) {
// this is when onResume() is called due to a screen state change
System.out.println("SCREEN TURNED ON");
} else {
// this is when onResume() is called when the screen state has not changed
System.out.println(" this is when onResume() is called when the screen state has not changed ");
}
super.onResume();
}
}
ScreenReceiver.java
package com.my.timeout;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class ScreenReceiver extends BroadcastReceiver
{
public static boolean screenOff;
@Override
public void onReceive(Context context, Intent intent) {
System.out.println("onReceive ");
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
screenOff = true;
System.out.println("SCREEN TURNED OFF on BroadcastReceiver");
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
screenOff = false;
System.out.println("SCREEN TURNED ON on BroadcastReceiver");
}
Intent i = new Intent(context, UpdateService.class);
i.putExtra("screen_state", screenOff);
context.startService(i);
}
}
UpdateService.java
package com.my.timeout;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
public class UpdateService extends Service {
public void onCreate() {
super.onCreate();
// register receiver that handles screen on and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new ScreenReceiver();
registerReceiver(mReceiver, filter);
}
@Override
public void onStart(Intent intent, int startId) {
boolean screenOn = intent.getBooleanExtra("screen_state", false);
if (!screenOn) {
System.out.println("Screen is off");
} else {
System.out.println("Screen is on");
}
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
Теперь я хочу установить будильник, когда экран выключен. Как я могу это сделать. Может кто-нибудь сказать мне? заранее спасибо.
