我需要将String的值传递给另一个类 从我的活动到使用服务的课程
我尝试过一个界面，但它不能，你只能附加一个片段，我不能尝试，因为它是一个在后台运行的类
我怎么能这样做？
主要活动
public class SettingsActivity extends AppCompatActivity {
private TriStateToggleButton mNotifications;
private ImageButton mButtonFinish;
private CardView mCardTermsPrivacy;
private CardView mCardLicenses;
private CardView mCardLogOut;
private CardView mCardDonations;
private FirebaseUser mUser;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
w.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
super.onCreate(savedInstanceState);
setContentView(R.layout.acitvity_settings);
mUser = FirebaseAuth.getInstance().getCurrentUser();
initPantalla();
CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
.setDefaultFontPath("fonts/RobotoLight.ttf")
.setFontAttrId(R.attr.fontPath)
.build()
);
}
private void initPantalla(){
mButtonFinish = (ImageButton) findViewById(R.id.imageButtonRegresaMeet);
mButtonFinish.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
mNotifications = (TriStateToggleButton) findViewById(R.id.triStateToggleNotifications);
mCardTermsPrivacy = (CardView) findViewById(R.id.cardViewTemrsPrivacy);
mCardLicenses = (CardView) findViewById(R.id.cardViewLicenses);
mCardDonations = (CardView) findViewById(R.id.cardViewDonations);
mCardLogOut = (CardView) findViewById(R.id.cardViewLogOut);
mCardTermsPrivacy.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
TermsDialogs termsDialogs = new TermsDialogs();
termsDialogs.setCancelable(true);
termsDialogs.show(getSupportFragmentManager(), null);
}
});
mCardLicenses.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
EasyLicensesDialog easyLicensesDialog = new EasyLicensesDialog(SettingsActivity.this);
easyLicensesDialog.setTitle("Licenses");
easyLicensesDialog.setCancelable(true);
easyLicensesDialog.show();
}
});
mCardLogOut.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
FirebaseAuth.getInstance().signOut();
if (AccessToken.getCurrentAccessToken() != null) {
LoginManager.getInstance().logOut();
}
Intent serviceIntent = new Intent(SettingsActivity.this ,FirebaseBackgroundService.class);
SettingsActivity.this.stopService(serviceIntent);
Intent intent = new Intent(SettingsActivity.this, RegisterActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
});
mNotifications.setOnToggleChanged(new TriStateToggleButton.OnToggleChanged() {
@Override
public void onToggle(TriStateToggleButton.ToggleStatus toggleStatus, boolean b, int i) {
switch(toggleStatus){
case on:
break;
case off:
break;
}
}
});
}
@Override
protected void attachBaseContext(Context newBase) {
super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
}
}
服务类，我需要在此
中传递一个字符串公共类FirebaseBackgroundService扩展了服务{
private FirebaseUser mUser;
private SharedPreferences preferences;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
super.onCreate();
FirebaseApp.initializeApp(getApplicationContext());
mUser = FirebaseAuth.getInstance().getCurrentUser();
if（mUser！= null）{
FirebaseUtils.getCHATSOLICITUDRef(mUser.getUid()).addChildEventListener(new ChildEventListener() {
@Override
public void onChildAdded(final DataSnapshot dataSnapshot, final String s) {
postNotif();
}
@Override
public void onChildChanged(DataSnapshot dataSnapshot, String s) {
}
@Override
public void onChildRemoved(DataSnapshot dataSnapshot) {
}
@Override
public void onChildMoved(DataSnapshot dataSnapshot, String s) {
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
}
private void postNotif(){
Intent notificationIntent = new Intent(getApplicationContext(), UserActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
Notification noti = new Notification.Builder(this)
.setContentTitle("Chat request")
.setContentText("You have pending chat requests")
.setSmallIcon(R.drawable.ic_dry_cleaning_with_mineral_spirits)
.setContentIntent(contentIntent)
.setSound(soundUri)
.build();
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
noti.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(0, noti);
}
}
