Re: [android-developers] Re: How to draw or write a text like MS-Paint in android using onTouch Event?
ACTION_MOVE in my app - I could be able to draw but not visible when im drawing and while moving my finger on a screen . Once after i release my finger , i can be able to see what i drew on the screen completely. When i'm trying to draw with my mouse, continuity is not good . Appearing as dots when iam moving my finger on the screen. Once i released my finger what i drew it appears fine !

[android-developers] Re: How to draw or write a text like MS-Paint in android using onTouch Event?
Why do you say MotionEvent.ACTION_MOVE is not working properly? Are you redrawing after a move event? You probably need to call invalidate().

I have tried alot, googled and as many possibilities coded on. No use. please anyone help/suggest about this issue ! Can refer this Video - http://www.youtube.com/watch?v=v65AUWyfjo0 I have created a panel with the collection of different colors, pencil, eraser and different shapes similar to MS-Paint. I could be able to draw or write on a screen using Touch Event method. But when i draw something on a screen (when i touch the screen), MotionEvent.ACTION_Down method is calling. So it works fine. When i release my finger from the screen, MotionEvent.ACTION_up method is calling and works fine. So, my problem is, like MS-PAINT i couldnt be able to see what i drew or wrote before i releasing the finger on a screen. For an example, can refer this video link- Using pencil. User can see when he dragged the shapes or trying to draw a pencil. Also, in this link user draws using pencil and it is visible without releasing a finger on the screen. But, when i draw something on the screen, once i released the finger only it appears. What i need is, when user touch the screen itself if he/she moves the finger on the screen, user must be able to see what they are trying to draw or write on the screen. For an Example : If i try to write some word like Apple on a screen , i am trying to put A . But when i write letter A, it is invisible unless i take my finger from the screen. Once if i released my finger from the screen after i drew letterA then only the text or picture has been appeared on a screen what i drew. So, I have done MotionEvent.ACTION_DOWN and MotionEVent.ACTION_UP. Its work fine. But, MotionEvent.ACTION_MOVE is not working properly. Can you suggest me or any ideas ?
