从新的Runnable（）获取价值

Question

How can I get the value accessed inside a Runnable ?
I'm trying to get the height from a LinearLayout and I able to see it with Log.d() but I'm just can't store the value in a member var.

This is the code where I see the height:

final ScrollView scrollView = (ScrollView) findViewById(R.id.scrollView);

scrollView.post(new Runnable() {
    @Override
    public void run() {
        setHeight(scrollView.getHeight());
        Log.d("height", scrollView.getHeight());
    }
});

Then I've tried to store it with a function but it always returns 0 :

protected void setHeight(int value){
    height = value;
}

How can I store the height value in the height var?

Answer 1

this is a classic case of inner class. Basically indirectly we are trying to store a value inside a non final variable height. Hence it could not store the variable. This is the route cause why you cant store the value of height.You should use other ways from setting the values inside the inner class.
