Step 4

Now, open your project and you will go to activity_main.xml and afterwards, you will build the design. You should choose toolbox and if you want some options (ProgressBar(small),ProgressBar(large), button), the drag and drop method is there to help.

Now, we can see Graphical User Interface design.

Step 5

Here, you need to build on the design and write .XML code.

activity_main.xml code.

<?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:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="xyz.rvconstructions.www.progresbarapp.MainActivity">
<Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="start" android:id="@+id/button" android:padding="10dp" android:background="#ee00ff" android:textColor="#fff" android:layout_centerVertical="true" android:layout_centerHorizontal="true" />
<ProgressBar style="?android:attr/progressBarStyleHorizontal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/progressBar" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
</RelativeLayout>

Step 6

Now, you will go to MainActivity.java page and build the Java code.

First of all, you will declare a file, which is an extension file.

android

Now, we can see the MainActivity.java code.

package xyz.rvconstructions.www.progresbarapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.graphics.Color;
import android.widget.ProgressBar;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ProgressBar firstProgressBar = (ProgressBar) findViewById(R.id.progressBar);
Button startButton = (Button) findViewById(R.id.button);
startButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
firstProgressBar.setVisibility(View.VISIBLE);
}
});
}
}

Step 7

Here, you will go to run it and select Run-> Run app option.

android

Here, you will choose Emulator or the devices and it is Nokia Nokia _X.

android

Step 8

Here, you can see the output.

android

You will see that ProgressBar(Normal) output Window.

android

Now, you will choose the ProgressBar (Horizontal) and then you can see that horizontal xml.code

<ProgressBar android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/progressBar" android:background="#fff700" android:layout_alignParentTop="true" android:max="100" android:progress="50" style="@style/Widget.AppCompat.ProgressBar.Horizontal" android:padding="20dp" android:layout_alignParentRight="true" android:layout_alignParentEnd="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true" />
