Android Custom Bar Chart | Dynamic Chart with different color in Android | Bar Chart Sample Program in Android

Hello Friends,
I am sharing very important code for draw bar chart in Android in different color and size.
I have one more article on simple bar chart but this one is more good.

1)Print Screen

2)MainActivity

package com.manish.barchartdemo;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
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);
  int colerloop[] = { 1, 2, 2, 2, 3, 3, 3, 3, 1, 1 };
  int heightLoop[] = { 300, 200, 200, 200, 100, 100, 100, 100, 300, 300 };
  for (int j = 0; j < colerloop.length; j++) {
   drawChart(1, colerloop[j], heightLoop[j]);
  }
 }

 public void drawChart(int count, int color, int height) {
  System.out.println(count + color + height);
  if (color == 3) {
   color = Color.RED;
  } else if (color == 1) {
   color = Color.BLUE;
  } else if (color == 2) {
   color = Color.GREEN;
  }

  for (int k = 1; k <= count; k++) {
   View view = new View(this);
   view.setBackgroundColor(color);
   view.setLayoutParams(new LinearLayout.LayoutParams(25, height));
   LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) view
     .getLayoutParams();
   params.setMargins(3, 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:gravity="bottom"
        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>

Thanks!
