Keyboard
public Keyboard (Context context, int layoutTemplateResId, CharSequence characters, int columns, int horizontalPadding)
Creates a blank keyboard from the given resource file and populates it with the specified characters in left-to-right, top-to-bottom fashion, using the specified number of columns.
If the specified number of columns is -1, then the keyboard will fit as many keys as possible in each row.
| Parameters | |

layoutTemplateResId |
int: the layout template file, containing no keys. |
characters |
CharSequence: the list of characters to display on the keyboard. One key will be created
for each character. |
columns |
int: the number of columns of keys to display. If this number is greater than the
number of keys that can fit in a row, it will be ignored. If this number is -1, the
keyboard will fit as many keys as possible in each row. |
