Easy way to implement 404 screens for android.

Including in your project


Gradle

Add Below codes to your root build.gradle file! (Not your module's build.gradle file).

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

And add a dependency code to your module's build.gradle file.

dependencies {
    implementation 'com.github.BlueCat-Community:View404:v1.0.0'
}

Usage

Make Layout XML File for Showing Error inside your project's res/layout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white">

    <TextView
        android:id="@+id/text_404"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:text="There is no results!"
        android:textSize="16sp"
        android:textStyle="bold" />

</RelativeLayout>

..And Add Error Layout Space in Your Layout.

<RelativeLayout
    android:id="@+id/errorLayout"
    android:background="#000000"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="50dp" />

Import following Package inside your Class.

import com.bluecat.view404.View404
import com.bluecat.view404.show404

Make Variable for View404.

private var view404: View404? = null

If you want to overlay 'not found' View on your ViewGroup,

if(view404 == null) {
    view404 = View404(this, R.layout.layout_404)
    errorLayout.show404(view404!!, R.anim.view404_fade_in_default)
}

If you want to dismiss 'not found' View on your ViewGroup,

if(view404 != null) {
    view404?.dismiss(R.anim.view404_fade_out_default)
    view404 = null
}
