[英]Start an activity from notification over the secure lockScreen
我試圖在安全鎖屏中顯示通知中的活動(在非安全鎖屏中我實現了這一點)。
我遵循 StackOverflow 的一些問題和答案,但沒有解決我的問題。
我將發布部分代碼。
這是在onCreate() 中執行的
Intent intentService = new Intent(this,NotificationService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
startForegroundService(intentService);
} else {
startService(intentService);
}
這是在onStartCommand 中執行的(在 onCreate 中嘗試過)
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);
}
這是在onCreate 中執行的
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" />
希望這部分代碼可以幫助您理解我的問題。 我在其他一些問題中讀到了人們做同樣的事情,但我不能。 怎么了? 如果您有其他解決方案,例如我可以在 lockScreen 中打開的小部件,請告訴我。
嘗試從通知創建中刪除
.setContentIntent(pendingIntent)
而是添加
rmv.setOnClickPendingIntent(R.id.layoutID, pendingIntent);
在通知上設置自定義視圖之前。 R.id.layoutID 應該是您的自定義通知布局的相對布局的 ID。
