What I am trying to do: I am trying to make a custom dialog in android With rounded corners.
What is happening: I am able to make custom dialog but it doesn't have rounded corners. I tried adding a selector but still I couldn't achieve rounded corners.
Below is my code for the same:
Java code:
private void launchDismissDlg() {
dialog = new Dialog(getActivity(), android.R.style.Theme_Dialog);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dlg_dismiss);
dialog.setCanceledOnTouchOutside(true);
Button btnReopenId = (Button) dialog.findViewById(R.id.btnReopenId);
Button btnCancelId = (Button) dialog.findViewById(R.id.btnCancelId);
btnReopenId.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
btnCancelId.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
dialog.setCanceledOnTouchOutside(false);
dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
dialog.show();
}
xml code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

I made a new way without having a background drawable is that make it have CardView as parent and give it a app:cardCornerRadius="20dp"
and then add this in the java class dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
It's another way to make it .
You can use the shape for the background as-
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent"/>
<corners android:radius="10dp" />
<padding android:left="10dp" android:right="10dp"/>
</shape>
Have a look on this for the details.
I implemented rounded dialog using CardView in the custom layout and setting its corner radius.
Here's my xml code.
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView

android:layout_margin="@dimen/padding_5dp"
app:cardCornerRadius="@dimen/dimen_20dp"
android:layout_height="wrap_content">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/main_gradient_bg"
android:paddingBottom="32dp">
<TextView
android:id="@+id/subdomain_label"
android:layout_width="wrap_content"

app:layout_constraintTop_toBottomOf="@id/subdomain_edit_text_bottom_sheet" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
After that, i called it in Kotlin as follows :-
val builder = AlertDialog.Builder(mContext)
val viewGroup: ViewGroup = findViewById(android.R.id.content)
val dialogView: View =
LayoutInflater.from(mContext).inflate(R.layout.subdomain_bottom_sheet,
viewGroup, false)
val alertDialog: AlertDialog = builder.create()
alertDialog.setView(dialogView,0,0,0,0)
alertDialog.show()
val windowParam = WindowManager.LayoutParams()
windowParam.copyFrom(alertDialog.window!!.attributes)
windowParam.width = AppConstant.getDisplayMetricsWidth(mContext) - 100
windowParam.height = WindowManager.LayoutParams.WRAP_CONTENT
windowParam.gravity = Gravity.CENTER
alertDialog.window!!.attributes = windowParam
alertDialog.window!!.setBackgroundDrawable
(ColorDrawable(Color.TRANSPARENT))
Where last line is very important. Missing that would cause a color(mostly white) to show behind the corners.
In Kotlin, I am using a class DoubleButtonDialog.Java with line window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
as important one
class DoubleButtonDialog(context: Context) : Dialog(context, R.style.DialogTheme) {
private var cancelableDialog: Boolean = true
private var titleDialog: String? = null
private var messageDialog: String? = null
private var leftButtonDialog: String = "Yes"
// private var rightButtonDialog: String? = null
private var onClickListenerDialog: OnClickListener? = null
override fun onCreate(savedInstanceState: Bundle?) {
window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
//requestWindowFeature(android.view.Window.FEATURE_NO_TITLE)
setCancelable(cancelableDialog)
setContentView(R.layout.dialog_double_button)
// val btnNegative = findViewById<Button>(R.id.btnNegative)
// btnNegative.visibility = View.GONE
// if (rightButtonDialog != null) {
// btnNegative.visibility = View.VISIBLE
// btnNegative.text = rightButtonDialog
// btnNegative.setOnClickListener {
// dismiss()
// onClickListenerDialog?.onClickCancel()
// }
// }
val btnPositive = findViewById<Button>(R.id.btnPositive)
btnPositive.text = leftButtonDialog
btnPositive.setOnClickListener {
onClickListenerDialog?.onClick()
dismiss()
}
(findViewById<TextView>(R.id.title)).text = titleDialog
(findViewById<TextView>(R.id.message)).text = messageDialog
super.onCreate(savedInstanceState)
}
constructor(
context: Context, cancelableDialog: Boolean, titleDialog: String?,
messageDialog: String, leftButtonDialog: String, /*rightButtonDialog: String?,*/
onClickListenerDialog: OnClickListener
) : this(context) {
this.cancelableDialog = cancelableDialog
this.titleDialog = titleDialog
this.messageDialog = messageDialog
this.leftButtonDialog = leftButtonDialog
// this.rightButtonDialog = rightButtonDialog
this.onClickListenerDialog = onClickListenerDialog
}
}
interface OnClickListener {
// fun onClickCancel()
fun onClick()
}
In layout, we can create a dialog_double_button.xml
<?xml version="1.0" encoding="utf-8"?>

You need to do the following:
Create a background with rounded corners for the Dialog's background:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#fff" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
</shape>
Now in your Dialog's XML file in the root layout use that background with required margin:
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:background="@drawable/dialog_background"
finally in the java part you need to do this:
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(layoutResId);
View v = getWindow().getDecorView();
v.setBackgroundResource(android.R.color.transparent);
This works perfectly for me.
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
this works for me
Create a xml in drawable ,say customd.xml.
then set it at background in your custom Dialog layout xml:
android:background="@drawable/customd"
finally in the java part for custom Dialog class you need to do this:
public class Customdialoque extends DialogFragment {
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
View view = inflater.inflate(R.layout.activity_customdialoque, container, false);
return view;
}
If you use Material Components:
CustomDialog.kt
class CustomDialog: DialogFragment() {
override fun getTheme() = R.style.RoundedCornersDialog
}
styles.xml
<style name="RoundedCornersDialog" parent="Theme.MaterialComponents.Dialog">
<item name="dialogCornerRadius">dimen</item>
</style>
With the Androidx library and Material Components Theme you can override the getTheme()
method:
import androidx.fragment.app.DialogFragment
class RoundedDialog: DialogFragment() {
override fun getTheme() = R.style.RoundedCornersDialog
//....
}
with:
<style name="RoundedCornersDialog" parent="@style/Theme.MaterialComponents.Dialog">
<item name="dialogCornerRadius">16dp</item>
</style>
Or you can use the MaterialAlertDialogBuilder
included in the Material Components Library:
import androidx.fragment.app.DialogFragment
import com.google.android.material.dialog.MaterialAlertDialogBuilder
class RoundedAlertDialog : DialogFragment() {
//...
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
return MaterialAlertDialogBuilder(requireActivity(), R.style.MaterialAlertDialog_rounded)
.setTitle("Test")
.setMessage("Message")
.setPositiveButton("OK", null)
.create()
}
}
with:
<style name="MaterialAlertDialog_rounded" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="shapeAppearanceOverlay">@style/DialogCorners</item>
</style>
<style name="DialogCorners">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">16dp</item>
</style>
If you don't need a DialogFragment
just use the MaterialAlertDialogBuilder
.
For API level >= 28 available attribute android:dialogCornerRadius
. To support previous API versions need use
<style name="RoundedDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="android:windowBackground">@drawable/dialog_bg</item>
</style>
where dialog_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item >
<shape >
<solid android:color="@android:color/transparent" />
</shape>
</item>
<item
android:left="16dp"
android:right="16dp">
<shape>
<solid
android:color="@color/white"/>
<corners
android:radius="8dp" />
<padding
android:left="16dp"
android:right="16dp" />
</shape>
</item>
</layer-list>
Here is the complete solution if you want to control the corner radius of the dialog and preserve elevation shadow
Dialog:
class OptionsDialog: DialogFragment() {
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup, savedInstanceState: Bundle?): View {
dialog?.window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
return inflater.inflate(R.layout.dialog_options, container)
}
}
dialog_options.xml layout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<androidx.cardview.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="40dp"
app:cardElevation="20dp"
app:cardCornerRadius="12dp">
<androidx.constraintlayout.widget.ConstraintLayout
id="@+id/actual_content_goes_here"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
</FrameLayout>
The key is to wrap the CardView with another ViewGroup (here FrameLayout) and set margins to create space for the elevation shadow.
For anyone who like do things in XML, specially in case where you are using Navigation architecture component actions in order to navigate to dialogs
You can use:
<style name="DialogStyle" parent="ThemeOverlay.MaterialComponents.Dialog.Alert">
<!-- dialog_background is drawable shape with corner radius -->
<item name="android:background">@drawable/dialog_background</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
Setting
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
will prevent dialog to cast a shadow.
Solution is to use
dialog.getWindow().setBackgroundDrawableResource(R.drawable.dialog_rounded_background);
where is R.drawable.dialog_rounded_background
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" android:padding="10dp">
<solid
android:color="@color/dialog_bg_color"/>
<corners
android:radius="30dp" />
</shape>
</item>
</layer-list>
You can simply use MaterialAlertDialogBuilder to create custom dialog with rounded corners.
First create a style for the material dialog like this :
<style name="MyRounded.MaterialComponents.MaterialAlertDialog" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
<item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.App.CustomDialog.Rounded
</item>
<item name="colorSurface">@color/YOUR_COLOR</item>
</style>
<style name="ShapeAppearanceOverlay.App.CustomDialog.Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">10dp</item>
</style>
then create a Alert Dialog object in Java class like this :
AlertDialog alertDialog = new MaterialAlertDialogBuilder(this,R.style.MyRounded_MaterialComponents_MaterialAlertDialog) // for fragment you can use getActivity() instead of this
.setView(R.layout.custom_layout) // custom layout is here
.show();
final EditText editText = alertDialog.findViewById(R.id.custom_layout_text); // access to text view of custom layout
Button btn = alertDialog.findViewById(R.id.custom_layout_btn);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "onClick: " + editText.getText().toString());
}
});
That's all you need to do.
simplest way is to use from
CardView and its card:cardCornerRadius
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:id="@+id/cardlist_item"
android:layout_width="match_parent"
android:layout_height="130dp"
card:cardCornerRadius="40dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="5dp"
android:layout_marginBottom="5dp"
android:background="@color/white">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="12sp"
android:orientation="vertical"
android:weightSum="1">
</RelativeLayout>
</android.support.v7.widget.CardView>
And when you are creating your Dialog
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
