android - ConstraintLayout: Realign baseline constraint in case if dependent view visibility was set to GONE -


is there way realign baseline constraint textview in case if dependent view visibility set gone?

my layout code:

<android.support.constraint.constraintlayout     android:layout_width="match_parent"     android:layout_height="wrap_content">      <textview         android:id="@+id/title"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="test title"         android:textcolor="@color/black"         android:textsize="24sp"         app:layout_constraintleft_toleftof="parent"         app:layout_constraintright_torightof="parent"/>      <textview         android:id="@+id/subtitle1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="subtitle 1"         android:textsize="11sp"         app:layout_constraintbaseline_tobaselineof="@+id/subtitle2"         app:layout_constrainthorizontal_chainstyle="packed"         app:layout_constraintleft_toleftof="parent"         app:layout_constraintright_toleftof="@+id/subtitlespace"         app:layout_constraintright_torightof="parent"/>      <android.support.v4.widget.space         android:id="@+id/subtitlespace"         android:layout_width="12dp"         android:layout_height="wrap_content"         app:layout_constraintleft_torightof="@+id/subtitle1"         app:layout_constraintright_toleftof="@+id/subtitle2"/>      <textview         android:id="@+id/subtitle2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_margintop="4dp"         android:text="subtitle 2"         android:textsize="14sp"         app:layout_constraintleft_torightof="@+id/subtitlespace"         app:layout_constraintright_torightof="parent"         app:layout_constrainttop_tobottomof="@+id/title"/>  </android.support.constraint.constraintlayout>

in case, layout looks this: enter image description here

when i'm setting subtitle2 textview visibility gone layout this: enter image description here

so i'm wondering if there constraint can realign baseline in case if dependent view missing.

alternate margins can specified gone widgets (see margins when connected gone widget), not aware of such alternative baselines.

one way satisfy requirement specify 0dp invisible textview has same characterisics of gone textview placed next same view. subtitle1 , subtitle2 tie baseline of new textview. though new textview doesn't show on screen , takes 0 width, still maintains baseline.

now, when subtitle2 made gone, subtitle1 move center maintain vertical position. (specifying 0dp , invisible null text redundant makes clear widget should not appear.)

here xml these changes:

<android.support.constraint.constraintlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="wrap_content">      <textview         android:id="@+id/title"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="test title"         android:textcolor="#ff000000"         android:textsize="24sp"         app:layout_constraintleft_toleftof="parent"         app:layout_constraintright_torightof="parent" />      <textview         android:id="@+id/subtitle1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="subtitle 1"         android:textsize="11sp"         app:layout_constraintbaseline_tobaselineof="@+id/viewforbaseline"         app:layout_constrainthorizontal_chainstyle="packed"         app:layout_constraintleft_toleftof="parent"         app:layout_constraintright_toleftof="@+id/subtitlespace"         app:layout_constraintright_torightof="parent" />      <android.support.v4.widget.space         android:id="@+id/subtitlespace"         android:layout_width="12dp"         android:layout_height="wrap_content"         app:layout_constraintleft_torightof="@+id/subtitle1"         app:layout_constraintright_toleftof="@+id/subtitle2" />      <textview         android:id="@+id/subtitle2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_margintop="4dp"         android:text="subtitle 2"         android:textsize="14sp"         android:visibility="gone"         app:layout_constraintbaseline_tobaselineof="@+id/viewforbaseline"         app:layout_constraintleft_torightof="@+id/subtitlespace"         app:layout_constraintright_torightof="parent"         app:layout_constrainttop_tobottomof="@+id/title" />      <textview         android:id="@+id/viewforbaseline"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_margintop="4dp"         android:textsize="14sp"         android:visibility="invisible"         app:layout_constraintright_torightof="parent"         app:layout_constrainttop_tobottomof="@+id/title" />  </android.support.constraint.constraintlayout>

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

android - Unable to generate FCM token from dynamically instantiated Firebase -

our business logic requires instantiate firebase during runtime. fetch firebase credentials (app id, api key etc.) default firebase location after knowing user's public key , create firebase instance using credentials. this means there 2 firebase instances used within app: the default "index" firebase gives credentials second the actual firebase intend use point forward the second firebase initialised this: firebaseapp app = firebaseapp.initializeapp(<context>, <options>, <app_label>); our problem traditional method of retrieving fcm token using firebaseinstanceidservice , ontokenrefresh() fails since ontokenrefresh() method called first firebase instance. directly calling string token = firebaseinstanceid.getinstance(app).gettoken(); returns null never ready when called. have tried polling test if token generated @ point. no luck. how can generate fcm token reliably firebase instance instantiated during runtime? i...
