ViewConfiguration
()
Public Methods
Returns a configuration for the specified context. The configuration depends on
various parameters of the context, like the dimension of the display or the
density of the display.
Parameters

public
static
int
getKeyRepeatTimeout
()
Returns

getLongPressTimeout
()
Returns
- the duration in milliseconds before a press turns into
a long press
public
static
int
getMaximumDrawingCacheSize

in milliseconds.
public
boolean
hasPermanentMenuKey
()
Report if the device has a permanent menu key available to the user.
As of Android 3.0, devices may not have a permanent menu key available.
Apps should use the action bar to present menu options to users.
However, there are some apps where the action bar is inappropriate
or undesirable. This method may be used to detect if a menu key is present.
If not, applications should provide another on-screen affordance to access
functionality.
Returns
- true if a permanent menu key is present, false otherwise.
