    <p>My application is calling an image from gallery and when you click on a place of the image, it voice out the colour. I'm facing a problem; I'm using a these codes to get the colour value for each place on the image. The funny thing is, it detects the colour values correctly (i.e. for red it shows r=255, g=0, b=0) but when it comes to saying the colour name (which I used 'TextToSpeech' for saying the colour name), it mostly says" The colour is black (unless you click on white, which it says Colour is white. Here is my code:</p> <pre><code> if ((Color.red(pixel) &amp; Color.blue(pixel) &amp; Color.green(pixel))&gt; 220) { if(TTSInitialized){ mTts.speak("Color is White", TextToSpeech.QUEUE_FLUSH, null); } textViewCol.setText("Color is White."); return true;} if ((Color.red(pixel) &amp; Color.blue(pixel) &amp; Color.green(pixel)) &lt; 10) { if(TTSInitialized){ mTts.speak("Color is Black", TextToSpeech.QUEUE_FLUSH, null); } textViewCol.setText("Color is Black."); return true;} if ((Color.red(pixel) &amp; Color.blue(pixel)) &gt; 120) { if(TTSInitialized){ mTts.speak("Color is Purple", TextToSpeech.QUEUE_FLUSH, null); } textViewCol.setText("Color is Purple."); return true;} if (Color.red(pixel) &gt; (Color.blue(pixel) &amp; Color.green(pixel))) { if(TTSInitialized){ mTts.speak("Color is RED", TextToSpeech.QUEUE_FLUSH, null); } textViewCol.setText("Color is Red."); return true;} </code></pre> <p>My application has Red, Green, Blue, Yellow, Purple, Cyan, Black and White. Now the question is: Is the way I'm writing the code correct? if not, what do you suggest? And Why is it always saying Black, no matter you click on red, blue or any other colour?!</p>

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.
