Questions:
I have a ImageView object inside a LinearLayout. I’m setting an animation to the ImageView which will move image view from point x to y. Now, starting point should be right corner of parent container. My question is , how do i get the dimension of the container in which the view is present. I don’t see view.getParent().getWidth() kind of method in view hierachy.
How to&Answers:
Perhaps you don’t need to because you can use % for animation like this:
<set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator">
<translate android:fromXDelta="100%p" android:toXDelta="0" android:duration="150" />
Answer：
Try this:
View parent = (View)view.getParent();
int width = parent.getWidth();
Answer：
Call after view added in a parent view, otherwise you would this exeption
java.lang.NullPointerException: Attempt to invoke virtual method ‘int android.view.View.getHeight()’
int height = ((View) view.getParent()).getHeight();
int width = ((View) view.getParent()).getWidth();
int mHeight = ((View) view.getParent()).getMeasuredHeight();
int mWidth = ((View) view.getParent()).getMeasuredWidth();
