progress-activity

If you are tired of constantly having to set up progress bars, empty views and error views, than this library is for you.

About

Using progress-activity which extends from RelativeLayout, you can easily add states like

• progress bar while the content is loading,
• empty view to indicate when there are no data to display,
• error view to indicate when something goes wrong with a button to try again.

Screenshots

Features

• show/hide progress bar,
• show/hide empty view,
• show/hide error view,
• show content when the data is ready to be displayed,

Usage

Add com.vlonjatg.progressactivity.ProgressActivity to your layout.

<com.vlonjatg.progressactivity.ProgressActivity
	android:id="@+id/progressActivity"
    android:layout_width="match_parent"
	android:layout_height="match_parent"
    android:layout_below="@+id/activityToolbar"
    progressActivity:loadingStateBackgroundColor="#FFFFFF"
    progressActivity:progressEmptyStateBackgroundColor="#fbc02d"
    progressActivity:progressErrorStateBackgroundColor="#42a5f5">

        <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:gravity="center"
            android:text="@string/hello_world" />

    </com.vlonjatg.progressactivity.ProgressActivity>

Then in your code:

To display the loading view:

progressActivity.showLoading();

To display the empty view:

progressActivity.showEmpty(emptyDrawable, "Empty Shopping Cart", 
		"Please add things in the cart to continue.");

To display the error view:

progressActivity.showError(errorDrawable, "No Connection",
		"We could not establish a connection with our servers. Try again when you are connected to the interne.",
        "Try Again", errorClickListener);
