void onKey (int primaryCode,
int[] keyCodes)
发送按键给听众。
| Parameters | |
|---|---|
primaryCode |
int: this is the key that was pressed |
keyCodes |
int: the codes for all the possible alternative keys with the primary code being the first. If the primary key code is a single character such as an alphabet or number or symbol, the alternatives will include other characters that may be on the same key or adjacent keys. These codes are useful to correct for accidental presses of a key adjacent to the intended key. |
void onPress (int primaryCode)
当用户按下某个键时调用。 这是在调用onKey(int, int[])之前发送的。 对于重复的键，这只会被调用一次。
| Parameters | |
|---|---|
primaryCode |
int: the unicode of the key being pressed. If the touch is not on a valid key, the value will be zero. |
void onRelease (int primaryCode)
当用户释放密钥时调用。 这是在onKey(int, int[])被调用后发送的。 对于重复的键，这只会被调用一次。
| Parameters | |
|---|---|
primaryCode |
int: the code of the key that was released |
void onText (CharSequence text)
向侦听器发送一系列字符。
| Parameters | |
|---|---|
text |
CharSequence: the sequence of characters to be displayed. |
