android - 在带 Remote 的 Android 电视中无法选择和单击动态 TextView

Question

我已经在 ListView 的行中创建了动态 TextView ，但是电视 Remote 无法聚焦 TextView ，我想知道 TextView 是否有任何我需要设置的特定属性？

源代码在这里:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    final EventData item = list.get(position);
    ViewHolder holder = null;
    if (convertView == null) {
        holder = new ViewHolder();
        inflater = (LayoutInflater) ctx
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.list_item_livesports, null);

        holder.nameTV = (TextView) convertView.findViewById(R.id.nameTV);
        holder.teamsTV = (TextView) convertView.findViewById(R.id.teamsTV);
        holder.startsTV = (TextView) convertView.findViewById(R.id.startTV);
        holder.channelLL = (TableLayout) convertView
                .findViewById(R.id.channelLL);
        holder.catIV = (ImageView) convertView.findViewById(R.id.catIV);
        convertView.setTag(holder);
    } else
        holder = (ViewHolder) convertView.getTag();

    holder.nameTV.setText(item.getName() + " : " + item.getTeams());
    holder.teamsTV.setText(item.getTeams());
    holder.startsTV.setText(item.getStarts());


    setDrawals(holder.catIV, item);

    TableRow tr_head = null;
    holder.channelLL.removeAllViews();
    for (int i = 0; i < item.linkList.size(); i++) {
        TextView v = new TextView(ctx);

        final Spanned name = Html.fromHtml("<font color='#0000FF'>"
                + item.linkList.get(i).channelName + "</font>");
        final String link = item.linkList.get(i).channelLink;
        v.setText(name);

        if (i == 0 || i == 2 || i == 4 || i == 6 || i == 8 || i == 10) {
            tr_head = new TableRow(ctx);
            tr_head.setLayoutParams(new LayoutParams(
                    LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
        }
        v.setPadding(20, 15, 20, 15);
        tr_head.addView(v);


        v.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // Toast.makeText(ctx, name, 1).show();
                linkListener.onLinkClicked(link);

            }
        });
        if (i == 0 || i == 2 || i == 4 || i == 6 || i == 8 || i == 10)
            holder.channelLL.addView(tr_head, new TableLayout.LayoutParams(
                    LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

    }

    return convertView;
}

这是在 RecyclerView 中吗？

对于 DPAD，除非您手动覆盖并编写 onKeyDown 方法，否则无法将焦点放在 TextView 上，该方法在敲击回车键时执行点击。

您可能想为整个 View 编写一个onClickListener，然后在检测到回车键时获取当前 View 并执行点击。

回收 View :

convertView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Do stuff
        }
    });

在你的 Activity 中:

public boolean onKeyDown(int keyCode, KeyEvent event) {
  switch(keyCode) {
    case KeyEvent.KEYCODE_DPAD_CENTER:
            mRecyclerView.findViewHolderForAdapterPosition(index).itemView.performClick();
            break;
  }   
}
