I have a styled TextView whose real text is populated dynamically at runtime. The Graphical Layout view is very useful for getting a feel on how this component works with others in terms of look and feel, etc. There is no sensible default to this text field and I wish it to be blank before being populated. If I don’t specify any text in the TextView declaration then the TextView is blank. I can set the text manually using:
<TextView ... android:text="Preview text"/>
and then switch to the Graphical Layout. However, I must remember to remove this or risk it being shipped in my production version.
Is there a way to specify text which is only seen in the Graphical Layout preview but not applicable at runtime?
EDIT: I’m using Eclipse ADT.
Yes you can with the design tools extension attributes in Android Studio.
Basically you define the tools namespace
Then use it to set your placeholder text.
<EditText tools:text="John Doe" android:layout_width="wrap_content" android:layout_height="wrap_content" />
This actually works with most (if not all xml attributes).
would set the preview visibility to “gone” but the runtime visibility would be unchanged.
I don’t believe there is, the only possible way is when you declare your TextView, you say after,
tv.setText(""); this way you will always find it blank at runtime
