I write my own text display component, which similar to TextView, but I wanna handle the spacing between words, and show cursor if user clicked on spacing, or show selection mark if user clicked on word.
I suppose this implementation is an easy job, I should write my own component extended from TextView, and overrides a few functions, such as onDraw(), onTouch(), etc. However, I found it's more difficult than my anticipation, after I study the source code of TextView. Because the TextPaint is a private member in TextView, and be used everywhere. That means if I wanna override onDraw(), I have to create my own TextPaint member, and override each functions which use the private TextPaint member. I don't understand why the TextPain member in TextView is private? I don't know why TextView do not allows subclass to use its members (TextPaint just one of them)? I just know this design is unfavorable to extend from standard component to develop my own component. Eventually, I write my own component extended from View, and write each function manually. I think components in SDK should not with private member, it is not convenient for Android designer, I suggests to review it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
