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:

• 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

######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.

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)'
}

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

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