Question

我尝试使用自定义列表视图中的点击按钮。但它不能正常工作。当我单击按钮来执行（例如，将文本更改为另一个按钮）时，它的工作方式，但它也适用于listview中的其他行！这是我在课堂上的onclick listener：

holder.btnLike.setOnClickListener( new OnClickListener() {
                int clicks = 0;
                @Override
                public void onClick(View arg0) {


                    clicks = clicks + 1;
                    if(clicks == 1){

                    }else if(clicks == 2) {
                        LikeToast.makeText(context, "Liked" , Toast.LENGTH_SHORT).show();
                        holder.btnLike.setText("Liked");
                        Drawable image = context.getResources().getDrawable( R.drawable.ic_action_liked );
                        int hlike = image.getIntrinsicHeight(); 
                        int wlike = image.getIntrinsicWidth();   
                        image.setBounds( 0, 0, wlike, hlike );
                        holder.btnLike.setCompoundDrawables( image, null, null, null );
                        //holder.btnLikes.setBackgroundDrawable(R.drawable.ic_action_liked);
                    } else{
                       clicks = 2;
                   }
                }
            });

和我的VoteListAdapter.class：

package com.skyline.jimmy;


public class VoteListAdapter extends BaseAdapter {

    ViewHolder holder;
    protected static final String CLIPBOARD_SERVICE = null;
    private final String TAG = "*** VoteListAdapter ***";
    private Context context;
    private ArrayList<Vote> votes;
    int showHideBtn = 0;
    public VoteListAdapter(Context context,List<Vote> voteList) {
        this.context =context;
        this.votes =(ArrayList<Vote>) voteList;

    }

    @Override
    public int getCount() {
        return votes.size();
    }

    @Override
    public Object getItem(int position) {
        return votes.get(position);
    }

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

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

        if (convertView == null) {
            holder      = new ViewHolder();
            convertView = LayoutInflater.from(context).inflate(R.layout.row, null);
            holder.tvName      = (TextView) convertView.findViewById(R.id.user);
            holder.tvComment   = (TextView) convertView.findViewById(R.id.tvComment);

            holder.tvLikes      = (TextView) convertView.findViewById(R.id.tvLikes);
            holder.ratingBar   = (RatingBar)convertView.findViewById(R.id.ratingBar);
            holder.share   = (ImageButton) convertView.findViewById(R.id.sharebtn);
            holder.copyJoke  = (Button) convertView.findViewById(R.id.copybtn);
            holder.btnLike  = (Button) convertView.findViewById(R.id.likebtn);
            holder.btnLiked  = (Button) convertView.findViewById(R.id.likedbtn);
            holder.btnLike.setTag(position);


            holder.copyJoke.setOnClickListener( new OnClickListener() {

                @Override
                public void onClick(View v) {

                    android.text.ClipboardManager clipboard = (android.text.ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE);
                    String Joke = votes.get(position).getComment();
                    clipboard.setText(Joke);

                    Toast toast3 = MyToast.makeText(context, "جک مورد نظر کپی شد", Toast.LENGTH_SHORT);
                    toast3.show();

                }
            });

            holder.btnLike.setOnClickListener( new OnClickListener() {
                int clicks = 0;
                @Override
                public void onClick(View arg0) {


                    clicks = clicks + 1;
                    if(clicks == 1){

                    }else if(clicks == 2) {
                        LikeToast.makeText(context, "Liked" , Toast.LENGTH_SHORT).show();
                        holder.btnLike.setText("Liked");
                        Drawable image = context.getResources().getDrawable( R.drawable.ic_action_liked );
                        int hlike = image.getIntrinsicHeight(); 
                        int wlike = image.getIntrinsicWidth();   
                        image.setBounds( 0, 0, wlike, hlike );
                        holder.btnLike.setCompoundDrawables( image, null, null, null );

请帮帮我。

Answer 1

您需要返回您单击的行并为该位置设置onclick侦听器，目前您的onclick将触发所有行

l.setAdapter(bAdaptor);

        l.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Batches bi = (Batches) parent.getAdapter().getItem(position);

                //Do what you want here

            }
        });

Answer 2

在你的xml文件中添加以下内容，你已经声明了按钮......这种情况正在发生，因为按钮点击监听器无法工作它实际上是整个listview的工作......

android:focusable="false"
android:focusableInTouchMode="false"

希望它有所帮助...
