AppCompat-Extension-Library

Google's AppCompat Design Library provides some awesome components for your development and design needs. For some applications though those just aren't enough. This library tries to fill the gap and provides additional common components building on the official AppCompat Design Library. If you have any additional features you'd like to see as part of this ongoing effort feel free to open a new issue.

Currently there are the following components:

There are wikis for every component that explain the setup in more depth, so be sure to check them out. Here's a link to the Wiki Home Page

Importing the library

This library is available as a gradle dependency via JitPack.io. Just add the following lines to your app module build.gradle:

repositories { 
    maven { url "https://jitpack.io" }
}
dependencies {
    compile 'com.github.TR4Android:AppCompat-Extension-Library:v0.5.1'
}

The latest Release is Release 0.5.1. You can download a sample.apk with this release.

AccountHeaderView

The AccountHeaderView is a component that allows easy switching between accounts in the navigation drawer by clicking on the avatars on the header or by choosing from the dropdown list.

Main features:

Works seamlessly with the AppCompat Design Library's NavigationView so you have full access to its features and can easily switch to an official account header implementation as soon as Google releases it.
Includes a dropdown list of accounts (and optionally account addition and managment items) by hooking up to the internal ListView of the AppCompat Design Library's NavigationView in an almost magical way!
Automatically creates placeholder avatars with the name's initials when an image is not set to an Account (see Google's Gmail).

Basic setup:

Use the following layout as the app:headerLayout of the AppCompat Design Library's NavigationView:

<com.tr4android.support.extension.widget.AccountHeaderView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@drawable/account_header_cover_background"
    android:layout_width="match_parent"
    android:layout_height="@dimen/account_header_height" />

Then add your accounts to the AccountHeaderView and add a listener for account selections:

accountHeaderView.addAccounts(new Account().setName("TR4Android").setEmail("[email protected]").setIconResource(R.drawable.account_drawer_profile_image_tr4android), ...);
accountHeaderView.setAccountSelectedListener(new AccountHeaderView.OnAccountSelectedListener() {
    @Override
    public void onAccountSelected(Account account) {   }

    @Override
    public void onAccountAddSelected() {   }

    @Override
    public void onAccountManageSelected() {   }
});

For the full documentation and customization options head over to the AccountHeaderView wiki.

FloatingActionMenu

The FloatingActionMenu is a wrapper for multiple FloatingActionButtons that takes the first FloatingActionButton as the main button that stays on screen and flings out all other FloatingActionButtons in speed dial fashion.

Main features:

Uses the AppCompat Design Library FloatingActionButton and thus has native elevation on Lollipop and above devices and even a shadow animation on pre-Lollipop devices!
Allows easy configuration of you main FloatingActionButton's icon animation: apply any rotation and optionally an alpha transition to a second icon (see Google's Inbox).
Works on all devices back to API level 7 just like the AppCompat Design Library!

Basic setup

<com.tr4android.support.extension.widget.FloatingActionMenu
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom" >
    
    <!-- Floating Action Buttons -->
    
</com.tr4android.support.extension.widget.FloatingActionMenu>

For the full documentation and customization options head over to the FloatingActionMenu wiki.

CircleImageView

The CircleImageView is a supercharged ImageView that provides the ability to set circular images as well as placeholders.

Main features:

Creates circular images using the AppCompat Support Library's RoundedBitmapDrawable which provides the best performance possible by using Romain Guys techniques!
Allows easy creation of placeholders with a colored circle and a letter (or letters) or an icon if an image should not available (see Google's Gmail email avatars).

Basic setup:

Instead of the default ImageView use the following in your layouts:

<com.tr4android.support.extension.widget.CircleImageView
    android:layout_width="40dp"
    android:layout_height="40dp" />

Then use setImage...() to set a circular image or setPlaceholder() to set a placeholder.

For the full documentation and customization options head over to the CircleImageView wiki.

Picker Dialogs

The AppCompatDatePickerDialog and AppCompatTimePickerDialog are native Android implementations of the picker dialogs detailed in the official Material Design guidelines.

Main features:

Uses the design presented in the Pickers section of the Material Design guidelines for a fully Material Design compliant user experience!
Works all the way back to API level 7 while maintaining important features (such as accessibility and right-to-left support) on API levels that support those.

Basic setup:

Setup your app theme by including the following lines (for dark themes remove the .Light part):

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- other attributes -->
    <item name="datePickerDialogTheme">@style/Theme.AppCompat.Light.DatePickerDialog</item>
    <item name="timePickerDialogTheme">@style/Theme.AppCompat.Light.TimePickerDialog</item>
</style>

Then use the AppCompatDatePickerDialog or AppCompatTimePickerDialog inside a DialogFragment (this example shows the AppCompatDatePickerDialog, but the process is quite similiar with the AppCompatTimePickerDialog):

public static class DatePickerFragment extends DialogFragment implements AppCompatDatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Create a new instance of AppCompatDatePickerDialog and return it
        return new AppCompatDatePickerDialog(getActivity(), this, 2017, 3, 13);
    }

    public void onDateSet(AppCompatDatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
    }
}

And later show this DialogFragment anywhere you need it:

DialogFragment datePicker = new DatePickerFragment();
datePicker.show(getSupportFragmentManager(), "datePicker");

For the full documentation and customization options head over to the Picker Dialogs wiki.

FlexibleToolbarLayout

The FlexibleToolbarLayout is a more advanced alternative to the already powerful CollapsingToolbarLayout that excels by also providing a scaled icon and subtitle along with the title.

Main features:

Collapses more than just a title! You can display a title, a subtitle and even an image which will all be scaled and animated while scrolling and you can style them to fit your personal needs.
Introduces more advanced elevation handling. The elevation you specified will no longer disappear when you have a solid background, but it still will if you have an immersive image.

Basic setup:

<android.support.design.widget.CoordinatorLayout>
    ...
    <android.support.design.widget.AppBarLayout>
        
        <com.tr4android.support.extension.widget.FlexibleToolbarLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:title="My title"
            app:subtitle="My subtitle"
            app:icon="@drawable/ic_my_icon"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <android.support.v7.widget.Toolbar
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin" />
        </com.tr4android.support.extension.widget.FlexibleToolbarLayout>
    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

Then update your FlexibleToolbarLayout at runtime by using setTitle(), setSubtitle or setIcon().

For the full documentation and customization options head over to the FlexibleToolbarLayout wiki.

Delightful Detail Drawables

The Delightful Detail Drawables provide ready-to-use implementations of the beautifully crafted animations presented in the Delightful Details section of the Material Design guidelines.

Main features:

Let your users control their media with style by using the MediaControlDrawable which animates between the icons for media playback control (play, pause and stop) and works back to API level 7.
Indulge your users while they are waiting for their content to load by using the IndeterminateProgressDrawable which provides a compatibility implementation of the progress animation that works back to API level 7.

Basic setup:

// build a new MediaControlDrawable
final MediaControlDrawable drawable = new MediaControlDrawable.Builder(this)
        .setColor(Color.WHITE) // ... more options
        .build();
// build a new IndeterminateProgressDrawable
final IndeterminateProgressDrawable drawable = new IndeterminateProgressDrawable.Builder(this)
        .setColor(Color.WHITE) // ... more options
        .build();

TypefaceCompat

The TypefaceCompat utility has been removed in version 0.5.0 of this library. The official downloadable fonts or FontsContractCompat should be used instead. While apps will continue to compile, the Roboto typeface will no longer be applied on pre-Lollipop devices as the associated resources have been removed to conserve space.

The TypefaceCompat is a utility for supporting the newest Typography. It automatically sets the text size, color and typeface for the styles specified in the guidelines.

Main features:

Easily setup with one line of code in your Activity.
Use one of the TextAppearance.AppCompat.xxx styles or use your own styles!
Automatically sets textSize, textColor and fontFamiliy for the TextAppearance.AppCompat.xxx styles and loads the new Roboto typeface on pre-Lollipop devices using a cache!

Basic setup:

In your Activity (for ease of use in your BaseActivity, if you have one) add the following line before super.onCreate():

public class SampleActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        TypefaceCompatFactory.installViewFactory(this);
        super.onCreate(savedInstanceState);
        ...
    }
}

Then use one of the TextAppearance.AppCompat.xxx styles via android:textAppearance="@style/TextAppearance.AppCompat.xxx" on your TextViews.

To achieve the correct line height use one of the predefined line_spacing_extra_xxx values via android:lineSpacingExtra="@dimen/line_spacing_extra_xxx" on your TextView.

For the full documentation and customization options head over to the TypefaceCompat wiki.
