    <p>Check out the <a href="http://xjaphx.wordpress.com/learning/tutorials/" rel="nofollow">Image Processing</a> to apply various effects on Image. It provides various effects to be applied on Image after capturing. </p> <p>Suppose i want to apply contrast effect on image then i will use the below method:</p> <blockquote> <pre><code>public static Bitmap createContrast(Bitmap src, double value) { // image size int width = src.getWidth(); int height = src.getHeight(); // create output bitmap Bitmap bmOut = Bitmap.createBitmap(width, height, src.getConfig()); // color information int A, R, G, B; int pixel; // get contrast value double contrast = Math.pow((100 + value) / 100, 2); // scan through all pixels for(int x = 0; x &lt; width; ++x) { for(int y = 0; y &lt; height; ++y) { // get pixel color pixel = src.getPixel(x, y); A = Color.alpha(pixel); // apply filter contrast for every channel R, G, B R = Color.red(pixel); R = (int)(((((R / 255.0) - 0.5) * contrast) + 0.5) * 255.0); if(R &lt; 0) { R = 0; } else if(R &gt; 255) { R = 255; } G = Color.red(pixel); G = (int)(((((G / 255.0) - 0.5) * contrast) + 0.5) * 255.0); if(G &lt; 0) { G = 0; } else if(G &gt; 255) { G = 255; } B = Color.red(pixel); B = (int)(((((B / 255.0) - 0.5) * contrast) + 0.5) * 255.0); if(B &lt; 0) { B = 0; } else if(B &gt; 255) { B = 255; } // set new pixel color to output bitmap bmOut.setPixel(x, y, Color.argb(A, R, G, B)); } } // return final image return bmOut; } </code></pre> </blockquote> <p>Use above method as:</p> <blockquote> <pre><code> BitMap bmp =BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length); //Here you can define your image and convert it into Bitmap. bmp = createContrast(bm,75); mImageView.setImageBitmap(bmp); </code></pre> </blockquote>

    1. COThanks for your suggestion, I want to apply affects at run time only not after capturing Image.

    2. COYes you can do that using the codes which are provided in the link. After capturing you can set image in `ImageView` and apply the effects on it by creating method for different effects which are available in the given link.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
