Generate 3D Pie Chart using Google Chart Tools

By using Google Chart Tools, we can generate 3D pie chart easily.

Java Code:

package com.Android3dPieChart;
 
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
 
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.Toast;
 
public class Android3dPieChartActivity extends Activity {
  
 final static String urlGoogleChart
  = "http://chart.apis.google.com/chart";
 final static String urlp3Api
  = "?cht=p3&chs=400x150&chl=A|B|C&chd=t:";
  
 EditText inputA, inputB, inputC;
 Button generate;
 ImageView pieChart;
  
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        inputA = (EditText)findViewById(R.id.adata);
        inputB = (EditText)findViewById(R.id.bdata);
        inputC = (EditText)findViewById(R.id.cdata);
        generate = (Button)findViewById(R.id.generate);
        pieChart = (ImageView)findViewById(R.id.pie);
        generate.setOnClickListener(generateOnClickListener);
    }
     
    Button.OnClickListener generateOnClickListener
    = new Button.OnClickListener(){
 
  @Override
  public void onClick(View arg0) {
   // TODO Auto-generated method stub
   String A = inputA.getText().toString();
   String B = inputB.getText().toString();
   String C = inputC.getText().toString();
   String urlRqs3DPie = urlGoogleChart
     + urlp3Api
     + A + "," + B + "," + C;
    
   Bitmap bm3DPie = loadChart(urlRqs3DPie);
   if(bm3DPie == null){
    Toast.makeText(Android3dPieChartActivity.this,
      "Problem in loading 3D Pie Chart",
      Toast.LENGTH_LONG).show();
   }else{
    pieChart.setImageBitmap(bm3DPie);
   }
  }};
   
 private Bitmap loadChart(String urlRqs){
  Bitmap bm = null;
  InputStream inputStream = null;
   
  try {
   inputStream = OpenHttpConnection(urlRqs);
   bm = BitmapFactory.decodeStream(inputStream);
   inputStream.close();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
   
  return bm;
 }
      
 private InputStream OpenHttpConnection(String strURL) throws IOException{
  InputStream is = null;
  URL url = new URL(strURL);
  URLConnection urlConnection = url.openConnection();
        
  try{
   HttpURLConnection httpConn = (HttpURLConnection)urlConnection;
   httpConn.setRequestMethod("GET");
   httpConn.connect();
    
   if (httpConn.getResponseCode() == HttpURLConnection.HTTP_OK) {
    is = httpConn.getInputStream(); 
   }
  }catch (Exception ex){
  }
   
  return is; 
 }
}
