How to make simple and fancy ProgressDialogs (Updated with androidx package)

You want to download a file from internet or load all the resources of your game or do any other task which will take some time, and simultaneously you also have to entertain the user. What will you do?

Here is the ProgressDialog class which will show a nice loading icon until your task gets completed.

This example shows three types of ProgressDialog, and further you can enhance as per your wish:

The Xml file loading_activity.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#81D4FA"
    android:gravity="center_vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="80dp"
        android:orientation="horizontal"
        android:gravity="top"
        android:weightSum="2">

        <Button
            android:id="@+id/spin_progressBTN"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:background="#0288D1"
            android:text="Spin"
            android:onClick="spinProgressDialog"
            android:textSize="15sp"
            android:layout_marginRight="5dp"
            android:textColor="#ffffff"/>

        <Button
            android:id="@+id/bar_progressBtn"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:background="#4FC3F7"
            android:text="Bar"
            android:layout_marginLeft="5dp"
            android:onClick="barProgressDialog"
            android:textSize="15sp"/>

    </LinearLayout>


    <Button
        android:layout_marginTop="5dp"
        android:padding="5dp"
        android:id="@+id/fancy_bar_progressBtn"
        android:layout_width="match_parent"
        android:layout_height="80dp"
        android:background="#0091EA"
        android:text="Fancy Bar"
        android:layout_marginLeft="5dp"
        android:onClick="fancyBarProgressDialog"
        android:textSize="15sp"
        android:textColor="#ffffff"/>


</LinearLayout>

The fancy_progress_bar.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:id="@android:id/background">
        <shape>
            <gradient
                android:startColor="#0277BD"
                android:centerColor="#0b131e"
                android:centerY="1.0"
                android:endColor="#0d1522"
                android:angle="270"
                />
        </shape>
    </item>

    <item android:id="@android:id/progress">
        <clip>
            <shape>
                <gradient
                    android:startColor="#80D8FF"
                    android:centerColor="#0091EA"
                    android:centerY="1.0"
                    android:endColor="#06101d"
                    android:angle="270"
                    />
            </shape>
        </clip>
    </item>
</layer-list>

The LoadingActivity.java:

package com.apps.yourappname;

import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;

public class LoadingActivity extends AppCompatActivity {

    private ProgressDialog mProgressDialog;

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

    public void spinProgressDialog(View v) {
        mProgressDialog = new ProgressDialog(LoadingActivity.this);
        mProgressDialog.setMessage("Simple Spin Progress Dialog");
        doProgress();
    }

    public void barProgressDialog(View v) {
        mProgressDialog = new ProgressDialog(LoadingActivity.this);
        mProgressDialog.setMessage("Simple Bar Progress Dialog");
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setMax(100);
        doProgress();
    }

    public void fancyBarProgressDialog(View v) {
        mProgressDialog = new ProgressDialog(LoadingActivity.this);
        mProgressDialog.setMessage("Fancy Bar Progress Dialog");
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        mProgressDialog.setProgressDrawable(getResources().getDrawable(R.drawable.fancy_progress_bar));
        mProgressDialog.setMax(100);
        doProgress();
    }

    void doProgress() {
        mProgressDialog.show();
        new Thread(){
            @Override
            public void run() {
                while(mProgressDialog.getProgress()<mProgressDialog.getMax()) {

                    try{
                        Thread.sleep(300);
                    }catch (InterruptedException e) {
                        e.printStackTrace();
                    }

                    handler.sendMessage(handler.obtainMessage());
                    if(mProgressDialog.getProgress()>=mProgressDialog.getMax()) {
                        mProgressDialog.dismiss();
                    }
                }
            }
        }.start();
    }

    Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            mProgressDialog.incrementProgressBy(1);
        }
    };
}

Just add the LoadingActivity's entry in Manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.app.yourappname">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".LoadingActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

No changes in the gradle files.
