XML tags in Android- Is there a reference

[ciliSuica]

I'm doing an Android XML GUI layout: \[code\]<EditTextPreferenceandroid:key="PREF_LT_500"android:title="Step 1"android:summary="aaaaa"android:inputType="number" android:defaultValue="http://stackoverflow.com/questions/12537404/0"android:dialogTitle="yyy" />\[/code\]1)I want the inputType to be a decimal. I'm struggling to find the XML value that can provide this. inputType="number" only permits the digits, not the ".". What must the inputType value be to force the input to be a decimal number? 2)In general, I find it time wasting and difficult to try and figure out the XML tags and permitted values. I'm wading through the Android references, and sometimes the tags are listed, but often not. Is there a reference for the XML GUI schema?3)I'm using Eclipse, and if I use the XML editor, it seems that some of the values are not resolving. It doesnt show the possible values for "inputType". Maybe my Eclipse is missing something?Thanks
