alerter克服了toast和snackbar的缺点，并布局很简单

生成

为了简单起见，Alerter采用了builder模式，以便于轻松集成到任何应用程序中。

可自定义的警报视图将动态添加到窗口的装饰视图中，覆盖所有内容。

安装配置

allprojects {

 repositories {

    jcenter()

    maven { url "https://jitpack.io" }

 }

}

build.gradle

dependencies {

    implementation 'com.github.tapadoo:alerter:$current-version'

}

使用

Activity -

Alerter.create(this@DemoActivity)

       .setTitle("Alert Title")

       .setText("Alert text...")

       .show()

Fragment -

Alerter.create(activity)

       .setTitle("Alert Title")

       .setText("Alert text...")

       .show()

展示 -

Alerter.isShowing()

隐藏 -

Alerter.hide()

定制

背景颜色

Alerter.create(this@DemoActivity)

       .setTitle("Alert Title")

       .setText("Alert text...")

       .setBackgroundColorRes(R.color.colorAccent) // or setBackgroundColorInt(Color.CYAN)

       .show()

图标

Alerter.create(this@DemoActivity)

       .setText("Alert text...")

       .setIcon(R.drawable.alerter_ic_mail_outline)

       .setIconColorFilter(0) // Optional - Removes white tint

       .setIconSize(R.dimen.custom_icon_size) // Optional - default is 38dp

       .show()

自定义屏幕持续时间（毫秒）

Alerter.create(this@DemoActivity)

       .setTitle("Alert Title")

       .setText("Alert text...")

       .setDuration(10000)

       .show()

无标题

Alerter.create(this@DemoActivity)

       .setText("Alert text...")

       .show()

添加 Click Listener

 Alerter.create(this@DemoActivity)

        .setTitle("Alert Title")

        .setText("Alert text...")

        .setDuration(10000)

        .setOnClickListener(View.OnClickListener {

            Toast.makeText(this@DemoActivity, "OnClick Called", Toast.LENGTH_LONG).show();

        })

        .show()

长的文本

 Alerter.create(this@DemoActivity)

        .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()

自定义进入/退出动画

  Alerter.create(this@KotlinDemoActivity)

         .setTitle("Alert Title")

         .setText("Alert text...")

         .setEnterAnimation(R.anim.alerter_slide_in_from_left)

         .setExitAnimation(R.anim.alerter_slide_out_to_right)

         .show()

可见性回调

 Alerter.create(this@KotlinDemoActivity)

        .setTitle("Alert Title")

        .setText("Alert text...")

        .setDuration(10000)

        .setOnShowListener(OnShowAlertListener {

            Toast.makeText(this@KotlinDemoActivity, "Show Alert", Toast.LENGTH_LONG).show()

        })

        .setOnHideListener(OnHideAlertListener {

            Toast.makeText(this@KotlinDemoActivity, "Hide Alert", Toast.LENGTH_LONG).show()

        })

        .show()

自定义字体和文本外观

 Alerter.create(this@DemoActivity)

        .setTitle("Alert Title")

        .setTitleAppearance(R.style.AlertTextAppearance_Title)

        .setTitleTypeface(Typeface.createFromAsset(getAssets(), "Pacifico-Regular.ttf"))

        .setText("Alert text...")

        .setTextAppearance(R.style.AlertTextAppearance_Text)

        .setTextTypeface(Typeface.createFromAsset(getAssets(), "ScopeOne-Regular.ttf"))

        .show()

退出

 Alerter.create(this@DemoActivity)

        .setTitle("Alert Title")

        .setText("Alert text...")

        .enableSwipeToDismiss()

        .show()

Progress Bar

 Alerter.create(this@DemoActivity)

        .setTitle("Alert Title")

        .setText("Alert text...")

        .enableProgress(true)

        .setProgressColorRes(R.color.colorAccent)

        .show()

带按钮

 Alerter.create(this@KotlinDemoActivity)

        .setTitle(R.string.title_activity_example)

        .setText("Alert text...")

        .addButton("Okay", R.style.AlertButton, View.OnClickListener {

            Toast.makeText(this@KotlinDemoActivity, "Okay Clicked", Toast.LENGTH_LONG).show()

        })

        .addButton("No", R.style.AlertButton, View.OnClickListener {

            Toast.makeText(this@KotlinDemoActivity, "No Clicked", Toast.LENGTH_LONG).show()

        })

        .show()

自定义layout

 Alerter.create(this@KotlinDemoActivity, R.layout.custom_layout)

        .setBackgroundColorRes(R.color.colorAccent)

        .also { alerter ->

            val tvCustomView = alerter.getLayoutContainer()?.tvCustomLayout
