Scale And Align In Custom Android Analogclock Hands
Solution 1:
Was this ever working? Try to add this to Clock constructor:
setWillNotDraw(false);
"If this view doesn't do any drawing on its own, set this flag to allow further optimizations. By default, this flag is not set on View, but could be set on some View subclasses such as ViewGroup. Typically, if you override onDraw(android.graphics.Canvas) you should clear this flag."
Edit:
If you want to re draw your view, you should call invalidate()
method
"Invalidate the whole view. If the view is visible, onDraw(android.graphics.Canvas) will be called at some point in the future. "
@OverrideprotectedvoidonSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
mChanged = true;
this.invalidate();
}
You don't even have to call invalidate(); if you just want to for example rotate the view:
@OverrideprotectedvoidonSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
mChanged = true;
setRotation(20);
}
Edit 2:
When you are setting bounds for a Drawable, the "right" value should be higher than "left" for example:
minuteHand.setBounds(x - (w / 2), y - (h / 2), x + (w / 2) + 4, y + (h / 4));
or
minuteHand.setBounds(x - (w / 2), y - (h / 2), x + (w / 2) + minuteHand.getIntrinsicWidth(), y + (h / 4));
