Android Custom ProgressBar :

Custom ProgressBar, Android Progressbar is shown when there is a background task running and to show the user about the status of the task.

Indeterminate ProgressBar is used when fetching the data or a task where the time i.e., duration of the task is not known.It may be completed quickly or may take some time there will be a circular type of animation shown for a unknown period.

In this tutorial we will create a indeterminate progress bar.

 

      2. Determinate ProgressBar

Now lets design a circular progressbar to be shown

 

Custom ProgressBar :

Designing a custom progress bar view you can alter the values of color, gradient and shape accordingly.

 

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" >

<shape
    android:innerRadiusRatio="3"
    android:shape="oval"
    android:thicknessRatio="20"
    android:useLevel="false" >
    <size
        android:height="100dp"
        android:width="100dp" />

    <gradient
        android:centerY="0.50"
        android:endColor="#ea1924"
        android:startColor="#FFFFFF"
        android:type="sweep"
        android:useLevel="false" />
</shape>

</rotate>

 

then add this progress shape to progress dialog

 

activity_main

 

<ProgressBar
    android:id="@+id/progressbar"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_centerInParent="true"
    android:indeterminateDrawable="@drawable/customprogress" />

 

<?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"
    android:background="@android:color/transparent"
    android:clickable="true">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true">

        <ProgressBar
            android:id="@+id/progressbar"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:layout_centerInParent="true"
            android:indeterminateDrawable="@drawable/customprogress" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_below="@+id/progressbar"
            android:layout_marginTop="3dp"
            android:textColor="#ffffff"
            android:text="Please wait"/>
    </RelativeLayout>
</RelativeLayout>

 

then make a custom progress dialog class which can be used any where in the app where we need to show progress dialog.

 

CustomProgressDialog

 

import android.app.AlertDialog;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;

/**
 * Created by Android on 11/13/2017.
 */

public class CustomProgressDialog extends AlertDialog {
    public CustomProgressDialog(Context context) {
        super(context);
        getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
    }

    @Override
    public void show() {
        super.show();
        setContentView(R.layout.custom_progress_dialog);
    }
}

 

then we can use this progress dialog as

 

CustomProgressDialog progressdialog = new CustomProgressDialog(this);
progressdialog.show();

 

MainActivity :

Providing the full code for Custom ProgressBar  indicator. I am providing the basic implementation you may customize it according to your requirements.

 

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    CustomProgressDialog progressdialog;

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

        progressdialog = new CustomProgressDialog(this);
        progressdialog.show();

        //progressdialog.dismiss(); // Activate when you want to stop progressdialog

    }
}

[/et_pb_text][et_pb_text admin_label=”Text” background_layout=”light” text_orientation=”left” use_border_color=”off” border_color=”#ffffff” border_style=”solid”]

Output :
