Setup Instructions

Add the following to your root (project) level build.gradle:

	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Add the library to your app's build.gradle

	dependencies {
		implementation 'com.github.AdityaAnand1:Morphing-Material-Dialogs:0.0.1-alpha2'
	}

Since we'll be morphing a floating action button into a dialog, you should also have the design support library:

	dependencies {
   		implementation "com.android.support:design:26.01"
	}

In your styles.xml, override the MorphDialog.Base themes (at least one, both if you wish to support light and dark themes for your app)

    <style name="MorphDialog.Custom.Light" parent="MorphDialog.Base.Light">
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
        <item name="colorAccent">@color/accent</item>
    </style>

    <style name="MorphDialog.Custom.Dark" parent="MorphDialog.Base.Dark">
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
        <item name="colorAccent">@color/accent</item>
    </style>

In your app's manifest file, add the following (at least one, both if you wish to support light and dark themes for your app)

   <activity
       android:name="in.adityaanand.morphdialog.MorphDialogActivity"
       android:theme="@style/MorphDialog.Custom.Light">
   </activity>
   <activity
       android:name="in.adityaanand.morphdialog.MorphDialogActivityDark"
       android:theme="@style/MorphDialog.Custom.Dark">
   </activity>

Usage instructions

This library mirror's a subset of afollestad/material-dialogs API. Currently, you can specify the title, content, positive button text and negative button text (all as CharSequences or string resource IDs).

new MorphDialog.Builder(this, fabView)
               .title("Title")
               .content("This is a sentence. Here is another one.") 
               .positiveText(R.string.ok)
               .useDarkTheme(true) //optional, default is false
               .show();

For example, if you have a floating action button in your activity

       <android.support.design.widget.FloatingActionButton
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:onClick="morph"/>

Then your morph() might look like:

    public void morph(View view) {
        new MorphDialog.Builder(this, (FloatingActionButton) view)
                .title("Title")
                .content("This is a sentence. Here is another one.")
                .show();
    }

Misc

P.S: We're at v0.0.1-alpha2 pre-release. Except things to change and break and evolve :)

What happens below API 21 (<Lollipop)?

Nothing. Since this library uses activity transitions which are properly supported only for Lollipop and up, the dialog pops up normally without any morphing animation below Lollipop.

Why does the library not support all of Material Dialogs features?

Doing so will mean that this library would have to duplicate the entire API of MaterialDialogs. I'm currently looking for a cleaner and leaner alternative to accomplishing this (Suggestions welcome)

I want to morph from something other than a fab/ I want to morph to something other than MorphDialog

Currently, this library does not support something-other-than-a-fab-to-something-other-than-a-material-dialog transition. If you'd like for it to work in another setting, say a custom view, head over to the standalone and check out the minimal implementation that will point you in the direction of a custom solution. Although, I'm certainly open to all ideas, including turning this into a generic morph-anything-to-anything library but doing so may or may not even be possible. Suggestions welcome
