Hello Android Developer!

Sometimes you need to show full screen loading dialog to prevent the user from input. In this part you will see a way to Display Full Screen Loading Dialog.

Step 1: Create Project

Create a new project in Android Studio from File ⇒ New Project and select Empty Activity from the templates.

Step 2: Create Loading Layout

Create a layout file in the layout resource directory.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_loading_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#835C5C5C"
    android:clickable="true"
    android:focusable="true"
    android:orientation="vertical"
    android:gravity="center">

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Loading..."
        android:textColor="#000000"
        android:layout_marginTop="5dp"/>
</LinearLayout>

Step 3: Modify Activity

Now open the activity layout where you want the full screen loading dialog to appear. Include the loading layout in it.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="www.CodestringZ.com" />

    <!--Other Views-->

    <!--Full Screen Progress Layout-->
    <include
        android:id="@+id/my_loading_layout"
        layout="@layout/my_loading_layout" />

</RelativeLayout>

Next open the Activity and modify it as follows:

package com.codestringz.mytestapp;

import android.os.Bundle;
import android.view.View;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity
{

    private View mLoading;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        setUIRef();

        //Display Loading
        showLoading();
    }

    private void setUIRef()
    {
        //Create a Instance of the Loading Layout
        mLoading = findViewById(R.id.my_loading_layout);
    }

    private void showLoading()
    {
        /*Call this function when you want progress dialog to appear*/
        if (mLoading != null)
        {
            mLoading.setVisibility(View.VISIBLE);
        }
    }

    private void hideLoading()
    {
        /*Call this function when you want progress dialog to disappear*/
        if (mLoading != null)
        {
            mLoading.setVisibility(View.GONE);
        }
    }
}

That’s it. Happy coding!
