An easy to use wrapper of the native Android Snackbar which stays visible across multiple activities. It provides different themes to start with, and allows you to easily manage common scenarios like success, warning, error, info.

Install

In your root/build.gradle:

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

In your app/build.gradle

dependencies {
  compile 'com.github.loregr:lgsnackbar:1.0.2'
}

Preparing

Setup with a default theme

Define your default theme using LGSnackbarManager.prepare(...), in your Application class in the #onCreate() method.

@Override
public void onCreate() {
    super.onCreate();
    LGSnackbarManager.prepare(getApplicationContext(),
                LGSnackBarThemeManager.LGSnackbarThemeName.SHINE);
                //....
}

You can check the available themes here.

Note: You can simply call LGSnackbarManager.prepare(getApplicationContext()), in this case SHINE theme will be automatically applied.

Setup with a custom theme

Create your own LGSnackbarTheme by passing 4 LGSnackBarStyle instances (one for each scenario of the theme) and the minHeight and the duration values that you want to apply to the Snackbar.

@Override
public void onCreate() {
    super.onCreate();
    LGSnackbarManager.prepare(getApplicationContext(),
                    customTheme());
                //....
}

//...

LGSnackBarTheme customTheme() {
    LGSnackBarStyle successStyle = new LGSnackBarStyle(successCustomColor,
            Color.WHITE,
            actionSuccessCustomColor,
            R.drawable.ic_done_white);

    LGSnackBarStyle warningStyle = new LGSnackBarStyle(warningCustomColor,
            Color.WHITE,
            actionWarningCustomColor,
            R.drawable.ic_warning_white);

    LGSnackBarStyle errorStyle = new LGSnackBarStyle(errorCustomColor,
            Color.WHITE,
            actionErrorCustomColor,
            R.drawable.ic_error_outline_white);

    LGSnackBarStyle infoStyle = new LGSnackBarStyle(infoCustomColor,
            Color.WHITE,
            actionInfoCustomColor,
           R.drawable.ic_info_outline_white);

    return new LGSnackBarTheme(successStyle, warningStyle, errorStyle, infoStyle, 60, Snackbar.LENGTH_LONG);
}

Usage

After preparing is done, in order to show a snackbar you can simply call:

LGSnackbarManager.show(SUCCESS, "Everything is looking good! Awesome!");

Woooo, done! :-)

Callbacks and actions

You can add a callback and/or an action to your snackbar by calling:

Callback:

LGSnackbarManager.show(SUCCESS, "Everything is looking good! Awesome!",
  new Snackbar.Callback() {
      @Override
      public void onShown(Snackbar sb) {
          super.onShown(sb);
          // LGSnackbar is now visible
      }

      @Override
      public void onDismissed(Snackbar transientBottomBar, int event) {
          super.onDismissed(transientBottomBar, event);
          // LGSnackbar is now hidden
      }
});

Action:

LGSnackbarManager.show(SUCCESS, "Everything is looking good! Awesome!",
  new LGSnackbarAction("Action", new View.OnClickListener() {
     @Override
     public void onClick(View view) {
       // Action fired
     }
}));

Custom snackbar

If for any reason you may need to display a custom snackbar without setting a whole new theme, you can use an LGSnackbarBuilder

new LGSnackbar.LGSnackbarBuilder(getApplicationContext(), "This is a custom bar")
        .duration(Snackbar.LENGTH_LONG)
        .actionTextColor(Color.GREEN)
        .backgroundColor(Color.GRAY)
        .minHeightDp(50)
        .textColor(Color.WHITE)
        .iconID(R.drawable.ic_info_outline_white)
        .callback(null)
        .action(null)
        .show();
