问题描述
我正在处理包含两个按钮的自定义通知。我正在使用RemoteViews，并使用了PendingIntent，以便它将在广播接收器中接收。在华为设备上可以正常工作，但在Oppo和Infinix设备上不能正常工作。
我正在清单中注册这样的广播接收器：
<receiver android:name="com.appedia.flashlight.torch.Notification_Receiver">
<intent-filter>
<action android:name="Notification_Flashlight"></action>
<action android:name="Notification_SOS"></action>
<action android:name="Notification_Delete"></action>
</intent-filter>
</receiver>
public void Notification()
{
builder = new NotificationCompat.Builder(this);
builder.setAutoCancel(true)
.setCustomContentView(remoteViews)
.setDeleteIntent(delete_pending_intent)
.setContentIntent(pendingIntent);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
{
builder.setSmallIcon(R.drawable.flashlight);
}
else
{
builder.setSmallIcon(R.mipmap.ic_launcher);
}
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O)
{
int importance = notificationmanager.IMPORTANCE_HIGH;
NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID,NOTIFICATION_CHANNEL_NAME,importance);
assert notificationmanager != null;
builder.setChannelId(NOTIFICATION_CHANNEL_ID);
notificationmanager.createNotificationChannel(notificationChannel);
}
assert notificationmanager != null;
}
public void NotificationItemsClickIntent()
{
Intent notification_intent = new Intent(getApplicationContext(),MainActivity.class);
pendingIntent = PendingIntent.getActivity(getApplicationContext(),notification_intent,0);
Intent notification_deleted_intent = new Intent("Notification_Delete");
notification_deleted_intent.putExtra("notification_delete","notification_delete");
delete_pending_intent = PendingIntent.getbroadcast(getApplicationContext(),notification_deleted_intent,PendingIntent.FLAG_UPDATE_CURRENT);
/* Pending Intent for Notification Flashlight Button */
//Intent with flashlight button for triggering broadcast Receiver when clicked from notification bar
Intent notification_flashlight_intent = new Intent("Notification_Flashlight");
notification_flashlight_intent.putExtra("notification_flashlight","Flashlight");
//start flashlight when notification bar button is clicked
PendingIntent notification_flashlight_button = PendingIntent.getbroadcast(this,notification_flashlight_intent,PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setonClickPendingIntent(R.id.notification_flashlight_button,notification_flashlight_button);
/* Pending Intent for Notification SOS Button */
//Intent with sos button for triggering broadcast Receiver when clicked from notification bar
Intent notification_sos_intent = new Intent("Notification_SOS");
notification_sos_intent.putExtra("notification_sos","SOS");
//start flashlight when notification bar button is clicked
PendingIntent notification_sos_button = PendingIntent.getbroadcast(this,notification_sos_intent,PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setonClickPendingIntent(R.id.notification_sos_button,notification_sos_button);
}
//broadcast receiver for getting battery percentage
private broadcastReceiver mBatInfoReceiver = new broadcastReceiver(){
@Override
public void onReceive(Context ctx,Intent intent) {
boolean isPlugged;
int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL,0);
remoteViews.setTextViewText(R.id.notification_battery_percent,String.valueOf(level) + "%");
int plugged = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED,-1);
isPlugged = plugged == BatteryManager.BATTERY_PLUGGED_AC || plugged == BatteryManager.BATTERY_PLUGGED_USB;
if(isPlugged)
{
remoteViews.setTextViewText(R.id.notification_battery_text,"Charging");
}
else
{
remoteViews.setTextViewText(R.id.notification_battery_text,"discharging");
}
NotificationItemsClickIntent();
Notification();
notificationmanager.notify(0,builder.build());
unregisterReceiver(mBatInfoReceiver);
}
};
在MainActivity的onCreate中启动通知服务并为电池信息注册广播接收器：
//Starting Notification Service
notificationmanager = (notificationmanager) getSystemService(NOTIFICATION_SERVICE);
remoteViews = new RemoteViews(getPackageName(),R.layout.notification_bar);
//for getting battery percentage (shows notification)
this.registerReceiver(this.mBatInfoReceiver,new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
通知广播接收器：
public class Notification_Receiver extends broadcastReceiver {
String notification_flashlight,notification_sos,notification_delete;
@Override
public void onReceive(Context context,Intent intent) {
notification_flashlight = intent.getExtras().getString("notification_flashlight");
notification_sos = intent.getExtras().getString("notification_sos");
notification_delete = intent.getExtras().getString("notification_delete");
if (notification_flashlight != null) {
Toast.makeText(context,"Flashlight",Toast.LENGTH_SHORT).show();
}
else if (notification_sos != null) {
Toast.makeText(context,"SOS",Toast.LENGTH_SHORT).show();
}
else if (notification_delete != null) {
Toast.makeText(context,"Delete",Toast.LENGTH_SHORT).show();
}
}
有人可以帮助我吗？我不知道我在做什么错
解决方法
我正在发布答案，这样也会对其他人有所帮助。我对广播接收器使用了隐式意图，而Android Oreo不建议这样做。因此，我必须使用明确意图，然后它才能开始正常工作。
Manifest.xml：
<receiver android:name="com.appedia.flashlight.torch.Notification_Receiver" />
MainActivity.java：
public void NotificationItemsClickIntent()
{
Intent notification_intent = new Intent(this,MainActivity.class);
pendingIntent = PendingIntent.getActivity(getApplicationContext(),notification_intent,0);
Intent notification_deleted_intent = new Intent(this,Notification_Receiver.class);
notification_deleted_intent.putExtra("notification_delete","notification_delete");
delete_pending_intent = PendingIntent.getBroadcast(this,1,notification_deleted_intent,PendingIntent.FLAG_UPDATE_CURRENT);
/* Pending Intent for Notification Flashlight Button */
//Intent with flashlight button for triggering Broadcast Receiver when clicked from notification bar
Intent notification_flashlight_intent = new Intent(this,Notification_Receiver.class);
notification_flashlight_intent.putExtra("notification_flashlight","Flashlight");
PendingIntent notification_flashlight_button = PendingIntent.getBroadcast(this,2,notification_flashlight_intent,PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.notification_flashlight_button,notification_flashlight_button);
/* Pending Intent for Notification SOS Button */
//Intent with sos button for triggering Broadcast Receiver when clicked from notification bar
Intent notification_sos_intent = new Intent(this,Notification_Receiver.class);
notification_sos_intent.putExtra("notification_sos","SOS");
PendingIntent notification_sos_button = PendingIntent.getBroadcast(this,3,notification_sos_intent,PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.notification_sos_button,notification_sos_button);
}
在广播接收器中，您必须检查操作而不是getExtras.getString()
public class Notification_Receiver extends BroadcastReceiver {
String notification_flashlight,notification_sos,notification_delete;
@Override
public void onReceive(Context context,Intent intent) {
notification_flashlight = intent.getAction() == "notification_flashlight";
notification_sos = intent.getAction() == "notification_sos";
notification_delete = intent.getAction() == "notification_delete";
if (notification_flashlight != null && notification_flashlight == true) {
Toast.makeText(context,"Flashlight",Toast.LENGTH_SHORT).show();
}
else if (notification_sos != null && notification_sos== true) {
Toast.makeText(context,"SOS",Toast.LENGTH_SHORT).show();
}
else if (notification_delete != null && notification_delete == true) {
Toast.makeText(context,"Delete",Toast.LENGTH_SHORT).show();
}
}
}
