java - Android - Image zoom library -


i have kind of use-case

user looking @ imageview, imageview should implement 2 types of gestures:

  • swipe left/right move previous/next image
  • zoom image (two-fingers, double-tap)

for swipe i've used implementation here https://stackoverflow.com/a/8806468/492624
can see here: https://github.com/smarek/simple-dilbert/blob/master/src/com/mareksebera/dilbert/activityswipedetector.java

for double-tap, two-fingers i've used library named photoview
can see here: https://github.com/smarek/simple-dilbert/blob/master/src/com/mareksebera/dilbert/imagezoomactivity.java

the problem is, i'm not able combine these 2 implementations.
i'd user have both options on 1 page, 1 idea rewrite "single imageview" "viewpager", implement paging on lower level (not ontouchlistener) , use photoview library provide zoom function.

possible user-scenario me:

  • if image not zoomed, user can use swipe gestures move through images
  • if image zoomed, user can work zoom , move in zoomed image, left-right swipe not work in case, user forced un-zoom able display another

so 2 qeustions on table

  1. whether user-scenario right , understandable
  2. if there option combine these or use library without need rewrite viewpager

can't use code sample of photoview?

this works me: https://play.google.com/store/apps/details?id=uk.co.senab.photoview.sample

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
