MaterialDialog library is built upon Google's Material Design library. This API will be useful to create rich, animated, beautiful dialogs in Android app easily. This library implements Airbnb's Lottie library to render After Effects animation in app. Refer this for Lottie documentation.
MaterialDialog library provides two types of dialog i.e.
Implementation of Material Dialog library is so easy. You can check /app directory for demo. Let's have look on basic steps of implementation.
In Build.gradle
of app module, include these dependencies. If you want to show animations, include Lottie animation library.
dependencies {
// Material Dialog Library
implementation 'com.shreyaspatil:MaterialDialog:1.0.0'
// Material Design Library
implementation 'com.google.android.material:material:1.0.0'
// Lottie Animation Library
implementation 'com.airbnb.android:lottie:3.0.6'
}
Setting Material Theme to app is necessary before implementing Material Dialog library. To set it up, update styles.xml
of values
directory in app.
<resources>
<style name="AppTheme" parent="Theme.MaterialComponents.Light">
<!-- Customize your theme here. -->
...
</style>
</resources>
These are required prerequisites to implement Material Dialog library.
As there are two types of dialogs in library. Material Dialogs are instantiated as follows.
MaterialDialog
class is used to create Material Dialog. Its static Builder
class is used to instantiate it. After building, to show the dialog, show()
method of MaterialDialog
is used.
MaterialDialog mDialog = new MaterialDialog.Builder(this)
.setTitle("Delete?")
.setMessage("Are you sure want to delete this file?")
.setCancelable(false)
.setPositiveButton("Delete", R.drawable.ic_delete, new MaterialDialog.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
// Delete Operation
}
})
.setNegativeButton("Cancel", R.drawable.ic_close, new MaterialDialog.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
dialogInterface.dismiss();
}
})
.build();
// Show Dialog
mDialog.show();
BottomSheetMaterialDialog
class is used to create Bottom Sheet Material Dialog. Its static Builder
class is used to instantiate it. After building, to show the dialog, show()
method of BottomSheetMaterialDialog
is used.
BottomSheetMaterialDialog mBottomSheetDialog = new BottomSheetMaterialDialog.Builder(this)
.setTitle("Delete?")
.setMessage("Are you sure want to delete this file?")
.setCancelable(false)
.setPositiveButton("Delete", R.drawable.ic_delete, new BottomSheetMaterialDialog.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
Toast.makeText(getApplicationContext(), "Deleted!", Toast.LENGTH_SHORT).show();
dialogInterface.dismiss();
}
})
.setNegativeButton("Cancel", R.drawable.ic_close, new BottomSheetMaterialDialog.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
Toast.makeText(getApplicationContext(), "Cancelled!", Toast.LENGTH_SHORT).show();
dialogInterface.dismiss();
}
})
.build();
// Show Dialog
mBottomSheetDialog.show();

Animations in this library are implemented using Lottie animation library. You can get free animations files here. You can find varieties of animation files on https://lottiefiles.com.
*.json
file downloaded from LottieFiles should be placed in android project. There are two ways to place animation file (*.json
).
For example, here delete_anim.json
animation file is used to show file delete animation.
Downloaded json file should placed in raw
directory of res
.
In code, setAnimation()
method of Builder
is used to set Animation to the dialog.
Prototype :
setAnimation(int resourceId)
Resource file should be passed to method. e.g. R.raw.delete_anim
.
MaterialButton mDialog = new MaterialDialog.Builder(this)
// Other Methods to create Dialog........
.setAnimation(R.raw.delete_anim)
//...
Downloaded json file should placed in asset
directory.
In code, setAnimation()
method of Builder
is used to set Animation to the dialog.
Prototype:
setAnimation(String fileName)
Only file name with extensions should passed to method.
MaterialButton mDialog = new MaterialDialog.Builder(this)
// Other Methods to create Dialog........
.setAnimation("delete_anim.json")
//...
To get View
of Animation for any operations, there is a method in Material Dialogs which returns LottieAnimationView
of dialog.
// Get Animation View
LottieAnimationView animationView = mDialog.getAnimationView();
// Do operations on animationView
There are three callback events and listeners for Dialog.
Following are interfaces for implementations:
OnShowListener()
- Listens for dialog Show event. ItsonShow()
is invoked when dialog is displayed.OnCancelListener()
- Listens for dialog Cancel event. ItsonCancel()
is invoked when dialog is cancelled.OnDismissListener()
- Listens for dialog Dismiss event. ItsonDismiss()
is dismiss when dialog is dismissed.
...
mDialog.setOnShowListener(this);
mDialog.setOnCancelListener(this);
mDialog.setOnDismissListener(this);
}
@Override
public void onShow(DialogInterface dialogInterface) {
// Dialog is Displayed
}
@Override
public void onCancel(DialogInterface dialogInterface) {
// Dialog is Cancelled
}
@Override
public void onDismiss(DialogInterface dialogInterface) {
// Dialog is Dismissed
}
}
This library is built using following open-source libraries.
