android - Invalidating 1 Custom View Causes All Custom Views In A View Group To Be Invalidated? -

-

i have custom view group. in custom view group number of custom views. custom views overlap each other in layout.

the overlapping views intential create "layers". 1 layer may create static content, layered view creates different animated content. problem comes when call .postinvalidate thread on 1 view animation runs @ 60fps. outside of layered views 60fps achievable device i'm using (galaxy s3).

inside custom view group, .invalidate causes 1 out of 2 hardware rendered views invalidate, , of software views invalidate it.

invalidate on view chain invalidate calls parents in view hierarchy. if hardware accelerated, may invalidate depending on flag in hardwarerenderer class. optimization. can check invalidate implementation. here link relevant call - invalidate() -check hardware acceleration

to sure, can check value of hardwarerenderer.render_dirty_regions on device in application.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
