Question

我创建了一个listView，其中有2个Item_separator和多个item_element。我想隐藏我的item_element的一部分，然后点击我的Item_separator的减号按钮元素（被红色包围的元素），如下所示：

这是我的项目元素布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="8dp"
    android:id="@+id/Item_Layout_Container">
    <!-- Icon -->

    <RelativeLayout
            android:id="@+id/Item_Layout_Icon"
            android:layout_width="81dp"
            android:layout_height="79dp"
            android:layout_alignParentLeft="true"
            android:layout_marginRight="8dp"
            android:background="@drawable/green_circle">
        <ImageView
            android:id="@+id/icon_symbol"
            android:layout_gravity="center"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerVertical="true"
            android:layout_centerHorizontal="true" />
    </RelativeLayout>
    <!-- Title -->
    <TextView
        style="@style/AppTheme.Text.Large"
        android:id="@+id/Item_Layout_Title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/Item_Layout_Icon"
        android:layout_toRightOf="@+id/Item_Layout_Icon"
        android:text="Title"
       />
    <!-- Description -->
    <TextView
        style="@style/AppTheme.Text.Medium"
        android:id="@+id/Item_Layout_Description"
        android:layout_below="@id/Item_Layout_Title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="description"
        android:layout_toRightOf="@+id/Item_Layout_Icon"
        />

  <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="15.30"
        android:id="@+id/Item_Layout_Time"
        android:layout_below="@+id/Item_Layout_Icon"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignRight="@+id/Item_Layout_Icon"
        android:layout_alignEnd="@+id/Item_Layout_Icon"
        android:gravity="center" />

</RelativeLayout>

在我的活动中，我使用了一个适配器来设置我的元素，我尝试这样做但它不起作用：

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;
    int type = getItemViewType(position);
    if (convertView == null) {
        holder = new ViewHolder();
        switch (type) {
            case TYPE_ITEM:
                convertView = mInflater.inflate(R.layout.item_layout, null);
                holder.Title = (TextView) convertView.findViewById(R.id.Item_Layout_Title);
                holder.Description = (TextView) convertView.findViewById(R.id.Item_Layout_Description);
                holder.Time = (TextView) convertView.findViewById(R.id.Item_Layout_Time);
                holder.Icon = (RelativeLayout) convertView.findViewById(R.id.Item_Layout_Icon);
                holder.IconState = (ImageView) convertView.findViewById(R.id.icon_symbol);    
                break;
            case TYPE_SEPARATOR:
                convertView = mInflater.inflate(R.layout.separator, null);
                holder.Title = (TextView) convertView.findViewById(R.id.textSeparator);
                holder.ButtonHide = (Button) convertView.findViewById(R.id.btnminus)
                break;
        }
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    switch (type) {
        case TYPE_ITEM:
            holder.Title.setText(mData.get(position).title);
            holder.Description.setText(mData.get(position).description);
            holder.Time.setText(mData.get(position).time);
            holder.Icon.setBackgroundResource(mData.get(position).iconLayout);
            holder.IconState.setImageResource(mData.get(position).iconImage);
            holder.Icon.setTag(mData.get(position).iconLayout);
            holder.Icon.setOnClickListener(myImageClickListener);
            break;
        case TYPE_SEPARATOR:
            holder.Title.setText(mData.get(position).title);
            textTag = mData.get(position).title;
            holder.ButtonHide.setOnClickListener(hideElement);
            break;
    }

    return convertView;
}

public View.OnClickListener hideElement = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        v.setVisibility(View.GONE);
    }
};

这是一个测试，但它不起作用;如何在第二个item_separator之后隐藏元素？谢谢

Answer 1

使用SearchResponse response = client.prepareSearch("my_index") .setTypes("my_output") .setSearchType(SearchType.DFS_QUERY_THEN_FETCH) .setQuery(QueryBuilders.queryStringQuery(query)) .setFrom(page).setSize(size) .execute() .actionGet();，您应该使用此块GONE容器。这样的事情：v.setVisibility(View.GONE); 你可以这样做：

public View.OnClickListener hideElement = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        holder.Description.setVisibility(View.GONE);
    }
};

并使用它：private class OnHideElementClickListener implements View.OnClickListener { private TextView mDescriptionBlockText; public OnHideElementClickListener(TextView descriptionBlock) { mDescriptionBlockText = descriptionBlock; } @Override public void onClick(View v) { mDescriptionBlockText.setVisibility(View.GONE); } }

Answer 2

您应该使用

 v.setVisibility(View.GONE);

而不是

v.setVisibility(View.INVISIBLE);

根据我的建议，如果你想隐藏视图，最好使用LinearLayout而不是RelativeLayout
