Why doesn’t Android dialog title appear on Marshmallow in Android version?… here is a solution to the problem.
Why doesn’t Android dialog title appear on Marshmallow in Android version?
I’m trying to create a custom dialog, here’s my code :
val myDialog = Dialog(this)
myDialog.setContentView(R.layout.my_dialog)
myDialog.setTitle("My Dialog!")
myDialog.setCancelable(true)
myDialog.show()
This is my_dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:text="Hello world!"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:textSize="30sp"/>
</android.support.constraint.ConstraintLayout>
I’ve run it on the android version of lollipop and it works fine Here is the screenshot on lollipop:
As you can see, the dialog title is showing up, but when I try to run on the Android version, the marshmallow header stops showing up, here is the screenshot on marshmallow :
As you can see, the dialog title is not displayed on the Android version of Marshmallow. I tried adding this line to show the header:
myDialog.create()
But the title is still not displayed. What am I going to do?
Solution
Have you tried applying a custom style… The dialog box is styled by a parent activity that may have been set to NoTitle.
<style name="CustomDialog" parent="@style/Theme.AppCompat.Light.Dialog">
<item name="android:windowNoTitle">false</item>
</style>
About Java code
new AlertDialog.Builder(new ContextThemeWrapper(Context, R.style.Dialog))
