隐藏和显示视图在视图上单击android BaseAdapter以解决listview问题

我试图在BaseAdapter的Listview的listitem的文本视图单击上显示隐藏的TextView。listitem的Textview在单击其他一些textviw时可见，但是列表中所有其他隐藏的Textview也可见，而不是listview中的特定项。我想让一个特定的列表项视图可见，而不是每个列表项的所有文本视图

下面是我的listitem的XML文件

listitem.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
        <TextView
            android:id="@+id/tvShowView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Textview to Click"          
            />
        <TextView
            android:id="@+id/tvToGetVisiable"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="This Textview will get visiable on tvShowView click"
            android:visibility="gone"
            />
</LinearLayout>

下面是我的适配器类：-

RewardsAdapter.java

public class RewardsAdapter extends BaseAdapter {

    private List<Rewards> liRewards;
    private Context mContext;  

    public RewardsAdapter(Context context, List<Rewards> liRewards) {
        mContext = context;
        liRewards = liRewards;      
    }

    @Override
    public int getCount() {
        return (liRewards == null || liRewards.isEmpty()) ? 0 : liRewards.size();
    }

    @Override
    public Object getItem(int position) {
        return liRewards;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;
        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            viewHolder = new ViewHolder();
            convertView = inflater.inflate(R.layout.listitem, null);
            viewHolder.tvShowView = (TextView) convertView.findViewById(R.id.tvShowView);
            viewHolder.tvToGetVisiable = (TextView)convertView.findViewById(R.id.tvToGetVisiable);

            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        final Rewards rewards = liRewards.get(position);

        viewHolder.tvShowView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                viewHolder.tvToGetVisiable.setVisibility(View.VISIBLE);
            }
        });

        return convertView;
    }

    private class ViewHolder {
        private TextView tvShowView;
        private TextView tvToGetVisiable;
    }
}

任何帮助都将不胜感激。

请使用此…

 @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;

            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            viewHolder = new ViewHolder();
            convertView = inflater.inflate(R.layout.listitem, null);
            viewHolder.tvShowView = (TextView) convertView.findViewById(R.id.tvShowView);
            viewHolder.tvToGetVisiable = (TextView)convertView.findViewById(R.id.tvToGetVisiable);

          //  convertView.setTag(viewHolder);

        final Rewards rewards = liRewards.get(position);

        viewHolder.tvShowView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                viewHolder.tvToGetVisiable.setVisibility(View.VISIBLE);
            }
        });

        return convertView;
    }

希望复制问题能够得到解决……

您必须保存文本视图的可见性状态。在保存

ViewHolder

并重用现有

ViewHolder

时。

 @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;

            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            viewHolder = new ViewHolder();
            convertView = inflater.inflate(R.layout.listitem, null);
            viewHolder.tvShowView = (TextView) convertView.findViewById(R.id.tvShowView);
            viewHolder.tvToGetVisiable = (TextView)convertView.findViewById(R.id.tvToGetVisiable);

          //  convertView.setTag(viewHolder);

        final Rewards rewards = liRewards.get(position);

        viewHolder.tvShowView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                viewHolder.tvToGetVisiable.setVisibility(View.VISIBLE);
            }
        });

        return convertView;
    }

在

getView

方法中

// set a default visibility to View for position
// apply visibility to view 
// When visibility change for any event then change visibility and save it for position
// when getView is called for a position then use previously saved visibility for position

谢谢，这很有帮助。
