形式はデバイスです。タイプコード値、つまり、デバイス、入力デバイスタイプ、キースキャンコード、および追加コード。これらは、kernel / include / linux / input.h（Androidソースコード）で具体的に定義されています。
Type: Input device type, keyboard and keypad (kaypad) frequently used in mobile phone systems are key settings EV_KEY, the trackball belongs to the relative device EV_REL, and the touch screen belongs to the absolute device EV_ABS Code: Key scan code, which is different from ASCII code and key code of KeyEvent in SDK. Value: additional code, 1/0 down/up Line 1: It can be understood as the beginning of a touch Line 2: Can be understood as a click start Line 3: Touch point x coordinates Line 4: Touch point y coordinate Line 5: Can be understood as the touch point size Line 6: Event synchronization (click to end) Line 7: End of touch Line 8: Event synchronization (end of event) Touching this 8 lines at a time is a must. If it is a longTouch, on the basis of the touch, repeat the 2nd to 6th lines several times, that is, look 放送イベント
