Not all view of elements in LinearLayout

  • jeanid

    There's a cardView there's a linearLayout with six elements. 

    <LinearLayout
                android:orientation="vertical"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

        &lt;/LinearLayout&gt;

    Initially, his visibility is gone, but when I press the button, I'm making LinearLayout Visible (View.Visible) and animating cardView, but instead of seeing all the elements, only one second element becomes visible.

    Here's animation code and height location. 

    package ru.landmarkstd.educt.FunctionalClass;
    

    import android.support.v7.widget.CardView;
    
import android.util.Log;
    
import android.view.View;
    
import android.view.ViewGroup;
    
import android.view.animation.Animation;
    
import android.view.animation.Transformation;
    

    import java.lang.reflect.Method;
    

    public class ExpandAndCollapce
    
{
    
public static void expand(CardView cardView,final ViewGroup v, int duration)
    
{
    
slide(cardView,v, duration, true);
    
}
    

    public static void collapse(CardView cardView,final ViewGroup v, int duration)
{
    slide(cardView,v, duration, false);
}

private static void slide(final CardView cardView, final ViewGroup v, int duration, final boolean expand)
{
    try
    {
        Method m = v.getClass().getDeclaredMethod("onMeasure", int.class, int.class);
        m.setAccessible(true);
        m.invoke(
                v,
                View.MeasureSpec.makeMeasureSpec(((View) v.getParent()).getMeasuredWidth(), View.MeasureSpec.AT_MOST),
                View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED)
        );
    } catch (Exception e) {
        Log.e("slideAnimation", e.getMessage(), e);
    }

    final int initialHeight = v.getMeasuredHeight();

    if (expand)
    {
        v.getLayoutParams().height = 0;
    }
    else
    {
        v.getLayoutParams().height = initialHeight;
    }
    v.setVisibility(View.VISIBLE);

    Animation a = new Animation()
    {
        @Override
        protected void applyTransformation(float interpolatedTime, Transformation t)
        {
            int newHeight = 0;
            if (expand)
            {
                newHeight = (int) (initialHeight * interpolatedTime);
            }
            else
            {
                newHeight = (int) (initialHeight * (1 - interpolatedTime));
            }
            v.getLayoutParams().height = newHeight;
            v.requestLayout();

            if (interpolatedTime == 1 &amp;&amp; !expand)
            {
                v.setVisibility(View.GONE);
            }
        }

        @Override
        public boolean willChangeBounds()
        {
            return true;
        }
    };

    a.setDuration(duration);
    v.startAnimation(a);
}

    

    }

    It's a full cardView.

&lt;/android.support.v7.widget.CardView&gt;

    

    </LinearLayout>

    And this is animation code from the main activation.

    open = (ImageView) itemView.findViewById(R.id.open);
    
cv = (CardView) itemView.findViewById(R.id.card_view);
    
linearLayoutDetails = (LinearLayout) itemView.findViewById(R.id.CardDetail);
    

    holder.open.setOnClickListener(new View.OnClickListener()
    
{
    
@Override
    
public void onClick(View v)
    
{
    
if (holder.linearLayoutDetails.getVisibility() == View.GONE)
    
{
    
ExpandAndCollapce.expand(holder.cv,holder.linearLayoutDetails, 500);
    

                    ObjectAnimator rotation = ObjectAnimator.ofFloat(v, "rotation", 180);
                rotation.setDuration(500);
                rotation.start();
            }
            else
            {
                ExpandAndCollapce.collapse(holder.cv,holder.linearLayoutDetails, 500);

                ObjectAnimator rotation = ObjectAnimator.ofFloat(v, "rotation", 0);
                rotation.setDuration(500);
                rotation.start();
            }
        }
    });
