[英]Start an activity from notification over the secure lockScreen
我试图在安全锁屏中显示通知中的活动(在非安全锁屏中我实现了这一点)。
我遵循 StackOverflow 的一些问题和答案,但没有解决我的问题。
我将发布部分代码。
这是在onCreate() 中执行的
Intent intentService = new Intent(this,NotificationService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
startForegroundService(intentService);
} else {
startService(intentService);
}
这是在onStartCommand 中执行的(在 onCreate 中尝试过)
public void crearNotificacion(){
RemoteViews rmv = new RemoteViews(getPackageName(),R.layout.notification_custom);
/*Intent intent = new Intent(this, wPerfil.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pIntent = PendingIntent.getActivity(this, 54, intent,PendingIntent.FLAG_UPDATE_CURRENT);*/
Intent intent = new Intent(this,NotificationIntentService.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getService(this,54,intent,
PendingIntent.FLAG_UPDATE_CURRENT);
createNotificationChannel();// Este trozo de codigo es para versiones +26
NotificationCompat.Builder builder = new NotificationCompat.Builder(this,CHANNEL_ID)
.setStyle(new NotificationCompat.DecoratedCustomViewStyle())
.setCustomContentView(rmv)
.setSmallIcon(R.drawable.ic_trasnparent)
.setPriority(NotificationCompat.PRIORITY_LOW)
.setContentIntent(pendingIntent)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setShowWhen(false)
.setGroupSummary(false)
.setAutoCancel(true);
startForeground(intentID,builder.build());
}
// CODIGO DE LA DOC DE ANDROID para versiones +26
private void createNotificationChannel() {
// Create the NotificationChannel, but only on API 26+ because
// the NotificationChannel class is new and not in the support library
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "Notificacion +26";
String description = "Notificacion para 26+";
int importance = NotificationManager.IMPORTANCE_LOW;
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, name, importance);
channel.setDescription(description);
// Register the channel with the system; you can't change the importance
// or other notification behaviors after this
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}
@Override
protected void onHandleIntent(Intent intent) {
if (intent != null) {
handleNotfication();
}
}
private void handleNotfication(){
Intent intent = new Intent(this,wPerfil.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
这是在onCreate 中执行的
if (Build.VERSION.SDK_INT >= 27) {
setShowWhenLocked(true);
setTurnScreenOn(true);
}else{
getWindow().addFlags(
WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON |
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON |
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-permission android:name="android.permission.ACTION_MANAGE_OVERLAY_PERMISSION" />
希望这部分代码可以帮助您理解我的问题。 我在其他一些问题中读到了人们做同样的事情,但我不能。 怎么了? 如果您有其他解决方案,例如我可以在 lockScreen 中打开的小部件,请告诉我。
尝试从通知创建中删除
.setContentIntent(pendingIntent)
而是添加
rmv.setOnClickPendingIntent(R.id.layoutID, pendingIntent);
在通知上设置自定义视图之前。 R.id.layoutID 应该是您的自定义通知布局的相对布局的 ID。
