Hint Not Displaying When numeric=“integer” in EditText

阅读更多关于 Hint Not Displaying When numeric=“integer” in EditText

The title is the question. Anybody know any solution? Please help me. Shaiful The XML attribute android:numeric is not a boolean value and "true" is not a valid parameter, it must be one ore more of "integer", "signed", "decimal". Per the sample you've posted, your issue is due to the choice of adding gravity to center the text. There is a known bug in the SDK that, as of 2.3, it looks like is still not fixed. This bug hides the hint text when android:singleLine and any custom value of android:gravity are set together. Your choice at this juncture really is to remove one or the other. Some

问题 I'm having a problem that I've never had before in almost three years of developing with Android... I want to take a picture and after the picture is taked, the EditText s of the activity become clear. What I'm doing is set the values of the EditText to Strings using getText().toString() to restore them after taking the picture.

Line Numbers, Code Highlighting in TextView

阅读更多关于 Line Numbers, Code Highlighting in TextView

I'm working on an 'IDE' for Android - it could be useful for editing short scripts / making quick adjustments to files. At the moment I'm just using a simple EditText, but I am wanting to add several features, for example Line Numbering down the left hand side of the EditText and Code Highlighting.

For the line numbering, could I have a thin vertical TextView that has the same text size as the EditText?? Yes, I'm aware editing code on a mobile

问题 I know there are a couple of questions already been asked, but I have a little different query. How do we put a limit on the maximum number of characters to be inputted in EditText ? Whether I do this android:maxLength="7" or this ((EditText)findViewById(R.id.zip)).setFilters(new InputFilter[] { new InputFilter.LengthFilter(7) }); I can still type into the text field, though it's not visible and not taken into account. If I keep typing, the input becomes invisible after the limit, but the
