Android Bar Chart Example | Simple Bar Chart Demo in Android | Charts in Android, Java

Hello Friends!
Today i am going to share very simple code for Draw Bar Chart in Android.
*No Library needed.
*No Canvas needed.
Just copy paste below code and enjoy :)

1)Print Screen


2)MainActivity


package com.manish.barchartdemo;

import android.os.Bundle;
import android.app.Activity;
import android.graphics.Color;
import android.view.View;
import android.widget.LinearLayout;

public class MainActivity extends Activity {
LinearLayout linearChart;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		linearChart=(LinearLayout)findViewById(R.id.linearChart);
		drawChart(5);
	}

	
	public void drawChart(int count) {
		System.out.println(count);
		
		for (int k = 1; k <= count; k++) {
			View view = new View(this);
			view.setBackgroundColor(Color.parseColor("#ff6233"));
			view.setLayoutParams(new LinearLayout.LayoutParams(30, 400));
			LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view
					.getLayoutParams();
			params.setMargins(5, 0, 0, 0); // substitute parameters for left,top, right, bottom
			view.setLayoutParams(params);
			linearChart.addView(view);
		}
	}
}

3)activity_main


<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" >

    <LinearLayout
        android:id="@+id/linearChart"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/view"
        android:layout_marginTop="50dp" >
    </LinearLayout>

    <View
        android:id="@+id/view"
        android:layout_width="match_parent"
        android:layout_height="25dp"
        android:layout_alignParentBottom="true"
        android:background="#00FF00" />

</RelativeLayout>
