Method Detail

getTargetRadius

public static float getTargetRadius(@NonNull
                                    android.content.Context context)

Gets the default target radius (in pixels). This is the radius of the circular area that can be touched in order to activate the handle.

Parameters:

context - the Context

Returns:

the target radius (in pixels)

getPressedHandle

@Nullable
public static Handle getPressedHandle(float x,
                                                float y,
                                                float left,
                                                float top,
                                                float right,
                                                float bottom,
                                                float targetRadius)

Determines which, if any, of the handles are pressed given the touch coordinates, the bounding box, and the touch radius.

Parameters:

x - the x-coordinate of the touch point

y - the y-coordinate of the touch point

left - the x-coordinate of the left bound

top - the y-coordinate of the top bound

right - the x-coordinate of the right bound

bottom - the y-coordinate of the bottom bound

targetRadius - the target radius in pixels

Returns:

the Handle that was pressed; null if no Handle was pressed

getOffset

@Nullable
public static android.util.Pair<java.lang.Float,java.lang.Float> getOffset(@Nullable
                                                                                     Handle handle,
                                                                                     float x,
                                                                                     float y,
                                                                                     float left,
                                                                                     float top,
                                                                                     float right,
                                                                                     float bottom)

Calculates the offset of the touch point from the precise location of the specified handle.

Returns:

the offset as a Pair where the x-offset is the first value and the y-offset is the second value; null if the handle is null
