GoogleProgressBar

Android library to display different kind of google related animations for the progressBar.

The demo app can be found in the play store.

These animations have been finished so far:

TODO

Different colors for the already existing `GoogleMusicDicesDrawable'. Either the whole dice or his faces.

I also would love to receive your pull requests to create any of the following animations or others that you think fit on this library:

NEXUS_CIRCLES:

Nexus 5 circles boot progress animation (Just the circles bouncing)
NEXUS_CROSS:

Galaxy nexus shinny cross boot animation

Usage

######Dynamically Add a ProgressBar to the xml layout:

     <ProgressBar
            android:id="@+id/google_progress"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_gravity="center"/>

Choose from the list of Drawables the one you want to use and place it in your code:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.inject(this);
        mProgressBar.setIndeterminateDrawable(new your_list_option.Builder(this)
                    .build());
        //...
    }

your_list_option can be replace for:

FoldingCirclesDrawable
GoogleMusicDicesDrawable
NexusRotationCrossDrawable

The more custom Drawables finished, the more options in this list.

Attributes depending on the drawable:

######Color

    mProgressBar.setIndeterminateDrawable(new you_list_option.Builder(this)
                                                             .colors(getResources().getIntArray(R.array.colors) //Array of 4 colors
                                                             .build());

FoldingCirclesDrawable
NexusRotationCrossDrawable

So far GoogleMusicDicesDrawable doesn't have color options. The animation speed can be modified easily with android:indeterminateDuration in the xml.

If not colors are define the 4 default google colors (red,blue, yellow and green) will be used.

######From XML

When you want to use the GoogleProgresBar from XML you need to add the following view to your layout:

    <com.jpardogo.android.googleprogressbar.library.GoogleProgressBar
            android:id="@+id/google_progress"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_gravity="center"
            gpb:type="your_list_option"/>

The require attribute gpb:type will specify the type of ProgressBar to display

your_list_option can be replace for:

folding_circles
nexus_rotation_cross
google_music_dices

The more custom Drawables finished, the more options in this list.

Each type of GoogleProgressBar have different attributes:

Attributes depending on type: ######Color

folding_circles
nexus_rotation_cross
- gpb:colors="@array/colors"
  - Optional, If not colors are define the 4 default google colors (red,blue, yellow and green) will be used.
  - It needs to be an array of 4 colors

So far google_music_dices doesn't have color options. The animation speed can be modified easily with android:indeterminateDuration in the xml.

Including in your project

You can either add the library to your application as a library project or add the following dependency to your build.gradle:

dependencies {
    compile 'com.jpardogo.googleprogressbar:library:(latest version)'
}

Proguard

In order to use this library with proguard you need to add this line to your proguard.cfg:

-keep class com.jpardogo.android.googleprogressbar.** { *; }
