Activity code

package com.vj.screencapture;

import com.google.android.gms.maps.GoogleMap;

import com.google.android.gms.maps.SupportMapFragment;

import android.support.v4.app.FragmentActivity;

import android.graphics.Bitmap;

import android.graphics.drawable.BitmapDrawable;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.ImageView;

import android.widget.LinearLayout;

public class MainActivity extends FragmentActivity {

        ImageView im;

         LinearLayout linerlay;

         GoogleMap gMap;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

       

        SupportMapFragment mapFrag = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);

          gMap = mapFrag.getMap();

          gMap.setMyLocationEnabled(true);

          gMap.getUiSettings().setZoomControlsEnabled(true);

          gMap.getUiSettings().setCompassEnabled(true);

          linerlay = (LinearLayout)findViewById(R.id.linearLayout);

       

          im = (ImageView)findViewById(R.id.imageView1);

        Button btn = (Button)findViewById(R.id.button1);

        btn.setOnClickListener(new OnClickListener() {

                    

                     @Override

                     public void onClick(View v) {

                            View v1 = im.getRootView().findViewById(R.id.map);

                 v1.setDrawingCacheEnabled(true);

                 Bitmap bm = v1.getDrawingCache();

                 BitmapDrawable bitmapDrawable = new BitmapDrawable(bm);

                           im.setImageBitmap(bm);

                     }

              });

      

    }

  

}

im.setImageBitmap(bm);
