How to use Line chart graph in android?

This example demonstrate about How to use Line chart graph in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Open build.gradle(module level) and add library dependency.

apply plugin: 'com.android.application'
android {
   packagingOptions {
      exclude 'META-INF/proguard/androidx-annotations.pro'
   packagingOptions {
      exclude 'META-INF/LICENSE'
      exclude 'META-INF/LICENSE.txt'
      exclude 'META-INF/license.txt'
      exclude 'META-INF/NOTICE'
      exclude 'META-INF/NOTICE.txt'
      exclude 'META-INF/notice.txt'
      exclude 'META-INF/ASL2.0'
   compileSdkVersion 28
   defaultConfig {
      applicationId "com.example.andy.myapplication"
      minSdkVersion 15
      targetSdkVersion 28
      versionCode 1
      versionName "1.0"
      testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
   buildTypes {
      release {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   implementation 'com.android.support:appcompat-v7:28.0.0'
   implementation 'com.android.support.constraint:constraint-layout:1.1.3'
   implementation 'com.github.PhilJay:MPAndroidChart:v3.1.0-alpha'
   testImplementation 'junit:junit:4.12'
   androidTestImplementation 'com.android.support.test:runner:1.0.2'
   androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

Step 3 − Open build.gradle(application level) and add library dependency.

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
   repositories {
   dependencies {
      classpath 'com.android.tools.build:gradle:3.2.1'
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
allprojects {
   repositories {
      maven { url 'https://jitpack.io' }
task clean(type: Delete) {
   delete rootProject.buildDir

Step 4 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   xmlns:app = "http://schemas.android.com/apk/res-auto"
   xmlns:tools = "http://schemas.android.com/tools"
   android:layout_width = "match_parent"
   android:layout_height = "match_parent"
   tools:context = ".MainActivity">
      android:id = "@+id/lineChart"
      android:layout_width = "fill_parent"
      android:layout_height = "fill_parent" />

In the above code, we have taken Line Chart view to show Line chart

Step 4 − Add the following code to src/MainActivity.java

package com.example.andy.myapplication;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import com.github.mikephil.charting.charts.LineChart;
import com.github.mikephil.charting.data.Entry;
import com.github.mikephil.charting.data.LineData;
import com.github.mikephil.charting.data.LineDataSet;
import com.github.mikephil.charting.utils.ColorTemplate;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
   LineChart lineChart;
   LineData lineData;
   LineDataSet lineDataSet;
   ArrayList lineEntries;
   protected void onCreate(Bundle savedInstanceState) {
      lineChart = findViewById(R.id.lineChart);
      lineDataSet = new LineDataSet(lineEntries, "");
      lineData = new LineData(lineDataSet);
   private void getEntries() {
      lineEntries = new ArrayList<>();
      lineEntries.add(new Entry(2f, 0));
      lineEntries.add(new Entry(4f, 1));
      lineEntries.add(new Entry(6f, 1));
      lineEntries.add(new Entry(8f, 3));
      lineEntries.add(new Entry(7f, 4));
      lineEntries.add(new Entry(3f, 3));

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –

In the above result, it is showing Line chart as per our data set values.
