android - How to know if the keyboard layout changes between numbers and letters? -


i have edittext users normaly enter numbers. therefore i'm using inputtype.type_class_number numerical soft keyboard. occationally though, users may want enter letters, have button switches between inputtype.type_class_number , inputtype.type_class_text.

works fine, found behaviour becomes strange on devices hardware keyboard. found this answer solves issue, can exclude keyboard switching functionality devices.

but there devices, e.g. asus transformer prime tablet, never changes software keyboard layout when switching between inputtype.type_class_number , inputtype.type_class_text. how can know if software keyboard change layout or not?

how can know if software keyboard change layout or not?

you can't. inputtype hint, not demand. input method editors ("software keyboards") don't have buttons (see graffiti). there no means of interrogating system determine capability of input method editors, largely because authors of input method editors not have declare capabilities. can honor or ignore inputtype, etc. see fit.

keyboard - C++ GetAsyncKeyState alternative -

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
