public static boolean isObjectSelected(Object object)
Filters objects against the ANDROID_OBJECT_FILTER
environment variable. This environment variable can filter objects
based on their class name and attribute values.
Here is the syntax for ANDROID_OBJECT_FILTER
:
ClassName@attribute1=value1@attribute2=value2...
Examples:
TextView
TextView@text=Loading.*@bottom=22
The class name and the values are regular expressions.
This class is useful for debugging and logging purpose:
if (DEBUG) { if (DebugUtils.isObjectSelected(childView) && LOGV_ENABLED) { Log.v(TAG, "Object " + childView + " logged!"); } }
NOTE: This method is very expensive as it relies heavily on regular expressions and reflection. Calls to this method should always be stripped out of the release binaries and avoided as much as possible in debug mode.
