Android Studio incorrectly flagging arguments annotated with Snackbar.Duration -


background

i wrote wrapper around default snackbar.make method apply custom styling snackbar instances. method signature of custom wrapper follows:

public static snackbar makecustom(         @nonnull view view,         @stringres int resid,         @snackbar.duration int duration)

where snackbar.duration annotation defined in android.support.design.widget.snackbar.java follows:

/**  * @hide  */ @intdef({length_indefinite, length_short, length_long}) @intrange(from = 1) @retention(retentionpolicy.source) public @interface duration {}

when invoke makecustom following arguments:

makecustom(         activity.findviewbyid(android.r.id.content),         messageresid,         snackbar.length_short);

i see following error in ide (android studio):

a screenshot android studio showing error associated parameter snackbar.length_short, reads: "value must >= 1 (was 01)"

i see no such error if directly invoke snackbar.make, has following signature:

public static snackbar make(         @nonnull view view,         @stringres int resid,         @duration int duration) {

a screenshot android studio showing no error associated parameter snackbar.length_short

it appear when used in own method signature, android studio fails recognize values satisfying either of following constraints

@intdef({length_indefinite, length_short, length_long}) @intrange(from = 1)

should considered valid, instead expecting values satisfy both of above constraints simultaneously (which impossible, since length_indefinite, length_short , length_long have values -2, -1 , 0 respectively).

questions

  • am applying snackbar.duration annotation properly?
  • if so:
    • is flagged error android studio bug?
    • is weird behavior perhaps why annotation marked hidden in source code?

delphi - Disable and change color of node in Treeview -

Image
i looking way of disabling proper nodes . let's have created simple treeview structure below: parent 1 (disable) parent 2 child 1 child 2 (disable) so far have found workaround how that, still doesn't work @ all. use onchanging event handler: procedure tform1.treeviewchanging(sender: tobject; node: ttreenode; var allowchange: boolean); begin if (node.text = 'parent 1') or (node.text = 'child 1') allowchange := false; end; it works, because can't click on node, issue after 'disabling' node way, color of parent 1 , child 1 nodes same other. way change color of nodes (grey)? or maybe know way disabling nodes in ttreeview component? to disable node, set enabled property false . disabled item displayed in gray color. to change normal color of nodes text, change ttreeview.font.color . to change color of disabled nodes text, use oncustomdrawitem event: procedure tform2.treeview1customdrawitem(sender: tcu...

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
