copied!<p>It seems this is a bug in the API. I did tests for 4 attributes: <code>gravity</code>, <code>text</code>, <code>textSize</code> and <code>textColor</code>. Here is the code I used:</p> <pre><code>private void processAndroidAttributes(final Context context, final AttributeSet attrs) { ATTRS = new Integer[] { android.R.attr.textSize, android.R.attr.text, android.R.attr.textColor, android.R.attr.gravity }; Arrays.sort(ATTRS); do { printPermutation(ATTRS); tryApplyingStyles(context, attrs, ATTRS); ATTRS = nextPermutation(ATTRS); } while ((ATTRS = nextPermutation(ATTRS)) != null); } </code></pre> <p>The method <code>processAndroidAttributes</code> tries applying all the listed attributes and checks if they were applied or defaults were used. For each iteration I print the array <code>ATTRS</code> contents and whether the real value was used (flagged with <code>1</code>) or default was used (flagged with <code>0</code>). Here is what I get after I run the above code (every iteration prints couple of lines):</p> <pre><code>[16842901,16842904,16842927,16843087] 1111 [16842901,16842904,16843087,16842927] 1110 [16842901,16842927,16842904,16843087] 1101 [16842901,16842927,16843087,16842904] 1101 [16842901,16843087,16842904,16842927] 1100 [16842901,16843087,16842927,16842904] 1100 [16842904,16842901,16842927,16843087] 1011 [16842904,16842901,16843087,16842927] 1010 [16842904,16842927,16842901,16843087] 1011 [16842904,16842927,16843087,16842901] 1011 [16842904,16843087,16842901,16842927] 1010 [16842904,16843087,16842927,16842901] 1010 [16842927,16842901,16842904,16843087] 1001 [16842927,16842901,16843087,16842904] 1001 [16842927,16842904,16842901,16843087] 1001 [16842927,16842904,16843087,16842901] 1001 [16842927,16843087,16842901,16842904] 1001 [16842927,16843087,16842904,16842901] 1001 [16843087,16842901,16842904,16842927] 1000 [16843087,16842901,16842927,16842904] 1000 [16843087,16842904,16842901,16842927] 1000 [16843087,16842904,16842927,16842901] 1000 [16843087,16842927,16842901,16842904] 1000 [16843087,16842927,16842904,16842901] 1000 </code></pre> <p>As you see this is almost as if expecting the array to be sorted, with only several outliers. I think it is a bug in the Android API as the documentation of <a href="http://developer.android.com/reference/android/content/res/Resources.Theme.html#obtainStyledAttributes%28int,%20int%5B%5D%29"><code>obtainStyledAttributes</code></a>, does not specify to expect any ordering of the attribute ids.</p>
