Android: Align Vertical and Raise 60 dp

Question

JavaScript

Hello!
There is a RelativeLayout layer:

<RelativeLayout
        android:id="@+id/redcircle"
        android:layout_width="8dp"
        android:layout_height="8dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:background="@drawable/circle" >
</RelativeLayout>

The question is how to "raise" it another 60dp relative to this center?

Answer 1

returnonly makes sense in synchronous functions. Like this:

function calc (a, b) {
    return a + b;
}

var c = calc (2, 2); // 4

In asynchronous functions, return does not make sense, since nothing is returned at the time the code is executed.
Think for yourself, in your case, before the onset of the mousemove event, it can take a very long time.
Therefore, they work differently with asynchronous code. Here is an example on callbacks:

document.addEventListener("mousemove", function (e) {
  var coord = [];
  coord[0] = e.clientX+'px';
  coord[1] = e.clientY+'px';

  next(coord); // вызов коллбэка
});

function next (coord) {
  console.log(coord);
}

There are other approaches besides callbacks, such as promises . jQuery has a cross browser implementation .

Answer 2

In the first variant, you have coord as a local variable.
And in the second option, you override the global coord with the local one.
Delete the selection and you will be happy

Answer 3

The problem was solved like this:

<RelativeLayout
        android:layout_width="8dp"
        android:layout_height="68dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" >
   	
      <ImageView
    android:id="@+id/redcircle"
          android:layout_width="8dp"
          android:layout_height="8dp"
          android:src="@drawable/circle" />        
  </RelativeLayout>

Thanks to all!
