Image Reflection in android

Hi,fellas

Working on my one of android project i got stuck on how to get image reflection on android

after messing a lot i successfully created image reflection with a little bit complicated android coding stuff. so as usual m goona describe how  to achieve this

Here we go..

1.Start fresh project name it  as ImageReflectionDemo

2.Create xml file

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    <ImageView

        android:id="@+id/bpsingh"

        android:layout_width="127dp"

        android:layout_height="wrap_content"

        android:layout_weight="0.21"

        

        android:src="@drawable/rihanna" />

</LinearLayout>

I just took one imageview with drawable image name bpsingh

3.Modify your Activity as

package com.parallelminds.appstore;

import android.app.Activity;

import android.graphics.Bitmap;

import android.graphics.Bitmap.Config;

import android.graphics.BitmapFactory;

import android.graphics.Canvas;

import android.graphics.LinearGradient;

import android.graphics.Matrix;

import android.graphics.Paint;

import android.graphics.Shader.TileMode;

import android.os.Bundle;

import android.widget.ImageView;

public class ImageReflection extends Activity{

ImageView imageview;

/** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.imagereflectiondemo); 

        

        //The gap we want between the reflection and the original image

        final int reflectionGap = 4;

        

        //Get you bit map from drawable folder

        Bitmap originalImage = BitmapFactory.decodeResource(getResources(), 

                R.drawable.bpsingh);

        

        int width = originalImage.getWidth();

        int height = originalImage.getHeight();

        

       

        //This will not scale but will flip on the Y axis

        Matrix matrix = new Matrix();

        matrix.preScale(1, -1);

        

        //Create a Bitmap with the flip matix applied to it.

        //We only want the bottom half of the image

        Bitmap reflectionImage = Bitmap.createBitmap(originalImage, 0, height/2, width, height/2, matrix, false);

        

            

        //Create a new bitmap with same width but taller to fit reflection

        Bitmap bitmapWithReflection = Bitmap.createBitmap(width 

          , (height + height/2), Config.ARGB_8888);

      

       //Create a new Canvas with the bitmap that's big enough for

       //the image plus gap plus reflection

       Canvas canvas = new Canvas(bitmapWithReflection);

       //Draw in the original image

       canvas.drawBitmap(originalImage, 0, 0, null);

       //Draw in the gap

       Paint deafaultPaint = new Paint();

       canvas.drawRect(0, height, width, height + reflectionGap, deafaultPaint);

       //Draw in the reflection

       canvas.drawBitmap(reflectionImage,0, height + reflectionGap, null);

       

       //Create a shader that is a linear gradient that covers the reflection

       Paint paint = new Paint(); 

       LinearGradient shader = new LinearGradient(0, originalImage.getHeight(), 0, 

         bitmapWithReflection.getHeight() + reflectionGap, 0x70ffffff, 0x00ffffff, 

         TileMode.CLAMP); 

       //Set the paint to use this shader (linear gradient)

       paint.setShader(shader); 

       //Set the Transfer mode to be porter duff and destination in

      // paint.setXfermode(new PorterDuffXfermode(Mode.DST_IN)); 

       

       //Draw a rectangle using the paint with our linear gradient

       canvas.drawRect(0, height, width, 

         bitmapWithReflection.getHeight() + reflectionGap, paint); 

       

       //Create an Image view and add our bitmap with reflection to it

       imageview=(ImageView) findViewById(R.id.rihana);

      // ImageView imageView = new ImageView(this);

       imageview.setImageBitmap(bitmapWithReflection);

}

}

       

4. Now run your project and you can see out put as

that's all

enjoy coding
