Alerter

General

This library aims to overcome the limitations of Toasts and Snackbars, while reducing the complexity of your layouts.

A customisable Alert view is dynamically added to the Decor View of the Window, overlaying all content.

Gradle

dependencies {
    implementation 'com.tapadoo.android:alerter:2.0.6'
}

Usage

With simplicity in mind, the Alerter employs the builder pattern to facilitate easy integration into any app.

From an Activity -

Alerter.create(this)
       .setTitle("Alert Title")
       .setText("Alert text...")
       .show();

Or from a Fragment -

Alerter.create(getActivity())
       .setTitle("Alert Title")
       .setText("Alert text...")
       .show();

To check if an alert is showing -

Alerter.isShowing();

To hide a currently showing Alert -

Alerter.hide();

Customisation

Background Colour

Alerter.create(this)
       .setTitle("Alert Title")
       .setText("Alert text...")
       .setBackgroundColorRes(R.color.colorAccent) // or setBackgroundColorInt(Color.CYAN)
       .show();

Icon

Alerter.create(this)
       .setText("Alert text...")
       .setIcon(R.drawable.alerter_ic_mail_outline)
       .setIconColorFilter(0) // Optional - Removes white tint
       .show();

On screen duration, in milliseconds

Alerter.create(this)
       .setTitle("Alert Title")
       .setText("Alert text...")
       .setDuration(10000)
       .show();

Without title

Alerter.create(this)
       .setText("Alert text...")
       .show();

Adding an On Click Listener

 Alerter.create(ExampleActivity.this)
        .setTitle("Alert Title")
        .setText("Alert text...")
        .setDuration(10000)
        .setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(ExampleActivity.this, "OnClick Called", Toast.LENGTH_LONG).show();
            }
        })
        .show();

Verbose text

 Alerter.create(ExampleActivity.this)
        .setTitle("Alert Title")
        .setText("The alert scales to accommodate larger bodies of text. " +
                 "The alert scales to accommodate larger bodies of text. " +
                 "The alert scales to accommodate larger bodies of text.")
        .show();

Visibility Callbacks

 Alerter.create(ExampleActivity.this)
        .setTitle("Alert Title")
        .setOnShowListener(new OnShowAlertListener() {
            @Override
            public void onShow() {
                Toast.makeText(ExampleActivity.this, "Alert Shown", Toast.LENGTH_LONG).show();
            }
        })
        .setOnHideListener(new OnHideAlertListener() {
            @Override
            public void onHide() {
                Toast.makeText(ExampleActivity.this, "Alert Hidden", Toast.LENGTH_LONG).show();
            }
         })
        .show();

Custom Fonts and Text Appearance

 Alerter.create(ExampleActivity.this)
                .setTitle("Alert Title")
                .setTitleAppearance(R.style.AlertTextAppearance_Title)
                .setTitleTypeface(Typeface.createFromAsset(getAssets(), "Pacifico-Regular.ttf"))
                .setText("Alert text...")
