How to add new key to Android from kernel to Android framework and Android Application Test

How to add new key to Android from kernel to Android framework and Android Application Test

Kernel layer:

1: We use kernel matrix-keypad to register 3*3 key

# Ifdef config_keyboard_matrix
/* Gpio matrix keyboard */
Static const uint32_t 89c64xx_matrix_keys [] = {
Key (0, 0, key_p1 ),
Key (0, 1, key_left ),
Key (0, 2, key_up ),

Key (1, 0, key_p2 ),
Key (1, 1, key_enter ),
Key (1, 2, key_right ),

Key (2, 0, key_frontdoor ),
Key (2, 1, key_down ),
Key (2, 2, key_start ),
};

Const struct matrix_keymap_data initi64xx_keymap_data = {
. Keymap = maid,
. Keymap_size = array_size (89c64xx_matrix_keys ),
};

/* Row key
Gpn0, gpn1, gpn2
Input --> extern interrupt
*/

Static const unsigned int initi64xx_keypad_row_gpios [] = {
144,145,146
};

/* Col key: gpn3, gpn6, gpn7 */
Static const unsigned int initi64xx_keypad_col_gpios [] = {
147,150,151
};

Static struct matrix_keypad_platform_data initi64xx_keypad_platform_data = {
. Keymap_data = & courseware 64xx_keymap_data,
. Row_gpios = 89c64xx_keypad_row_gpios,
. Num_row_gpios = array_size (89c64xx_keypad_row_gpios ),
. Col_gpios = 89c64xx_keypad_col_gpios,
. Num_col_gpios = array_size (89c64xx_keypad_col_gpios ),
. Active_low = 1,

. Debounce_ms = 20,
. Col_scan_delay_us = 5,
};

Static struct platform_device initi64xx_matrix_keyboard = {
. Name = "Matrix-keypad ",
. ID =-1,
. Dev = {
. Platform_data = & 89c64xx_keypad_platform_data,
},
};

Static struct platform_device * smdk6410_devices [] _ initdata = {
# Ifdef config_keyboard_matrix
& Amp; cloud64xx_matrix_keyboard,
# Endif
};

2: We add new defition of key_p1, key_p2, key_frontdoor, key_start in Linux/include/Linux/input. h
/* Jiujin. Hong 2011/1011
# Define key_p1 247
# Define key_p2 248
# Define key_frontdoor 249
# Define key_start 250
/* End */

3: We make menuconfig to support matrix keyboard arch to register into Kernel Input subsystem

Qwerty. KL (not missing)

Key 247 p1
Key 248 p2
Key 249 frontdoor
Key 250 start

Android Application Test:

1: Android has setfocusable/request focus for view if you use onkeydown, so we need dispatch event

// Since we register new keycode map in frameworks/base/CORE/RES/values/attrs. xml
// So we use it to judge
// Keycode_p1 --- 92
// Keycode_p2 --- 93
// Keycode_frontdoor --- 94
// Keycode_start --- 95
@ Override
Public Boolean dispatchkeyevent (keyevent event ){
Int action = event. getaction ();
Int keycode = event. getkeycode ();
System. Out. println ("keycode --->" + keycode );
Switch (keycode ){

Case 92:

// Todo
System. Out. println ("p1 down ");
}
