setvisibility（view.oneible）在setvisibility之后无效（view.gone）

Question

I saw some post about this and I understood the problem. But how can go around it? I have ListView with item that can be expanded but once the view is gone it cannot be visible again, unless it has a free space. How to make that space?

private void mySetOnItemListener() {
    l.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View view,
            int position, long arg3) {
        Log.d("onItemClick","called");
        LinearLayout ll = (LinearLayout)view.findViewById(R.id.llOpenedField);
        ll.setVisibility(View.VISIBLE);
    }
    });
}

my viewLayout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" 
    android:descendantFocusability="blocksDescendants">

    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="horizontal"
        android:weightSum="5" >

        <TextView
            android:id="@+id/tv_name"
            android:layout_width="0px"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="4"
            android:padding="7dp"
            android:text="item"
            android:textColor="@android:color/background_dark"
            android:textSize="25dp" />
    </LinearLayout>

      <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/llOpenedField"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="horizontal"

         >

        <ImageButton
            android:id="@+id/ibInformation"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:src="@drawable/info" />

    </LinearLayout>

</LinearLayout>

the LinearLayout android:id="@+id/llOpenedField" is what im trying to make gone at start .

i put the gone attribute in the getView() inside BaseAdapter .

Answer 1

If you put the code making an element visible into its onClickListener, it won't be reachable (if it consumes none of the screen-space, you won't be able to click on it). You should put a layout with a minimal height below it, and when your view l becomes gone, the new layout shell become visible, and it should get the visible-making onClickListener. This way, after your View becomes gone, this new layout will be able to bring it back.

please check this answer. This answer work for me.

TranslateAnimation translateAnimation = new TranslateAnimation(0, 50, 0, 0);
          int animationTime = 200;
          translateAnimation.setDuration(animationTime);
          translateAnimation.setFillEnabled(true);
          translateAnimation.setFillAfter(true);
          yourView.startAnimation(translateAnimation);
          yourView.setVisibility(View.VISIBLE);

Answer 3

try this and modify according to your need ,this is not list item on which i am clicking

Make Linear layout android:visibility="gone" ; first and do this this.

@Override
    public void onClick(View v)
    {
        LinearLayout ll = (LinearLayout)findViewById(R.id.vis);

        if(v == ex)
        {
            if(ll.getVisibility() == View.VISIBLE)
                ll.setVisibility(View.GONE);
            else
                ll.setVisibility(View.VISIBLE);
        }

update :- These are lines for you.. which will make proper expand and collapse ,and no free space will be there

if(ll.getVisibility() == View.VISIBLE)
                    ll.setVisibility(View.GONE);
                else
                    ll.setVisibility(View.VISIBLE);
