如何添加那些依赖于TextView的文本在ListView的ImageView [英] How to add ImageView's that are depending on the text of the TextView in a ListView

问题描述

我有一个自定义的的ListView 与 RowItem 包含的TextView 和的ImageView 。
在 RowItems 将被动态添加。

I have a custom ListView with a RowItem that contains TextView and a ImageView . The RowItems will be added dynamically.

我只是想知道如何添加的ImageView 来在一个特定的文本的TextView 。

I just want to know how to add the ImageView to a specific text in the TextView.

所以，如果在的TextView 表示标题1时，的ImageView R.drawable.ic_title1应该是添加到 RowItem 。

So if in the TextView stands "Title1" ,the ImageView "R.drawable.ic_title1" should be added to the RowItem .

下面是我的code

class SessionItemAdapter extends ArrayAdapter<Map> {

        final ArrayList<Map> values;
        Context context;

        SessionItemAdapter(Context context, ArrayList<Map> values) {
            super(context, R.layout.session_list_layout_row, values);
            this.values = values;
            this.context = context;
        }


        @Override
        public View getView(final int position, View view, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View rowView = inflater.inflate(R.layout.session_list_layout_row, parent, false);

            TextView tv = (TextView) rowView.findViewById(R.id.stepTime);
            final int rowId = (Integer) values.get(position).get("id");
            int beepStringId = getResources().getIdentifier("exercise_typ_" + values.get(position).get("type"), "string", getPackageName());

            rowView.setTag(rowId);

            tv.setText(getResources().getString(beepStringId));
            ImageView image =(ImageView) rowView.findViewById(R.id.imageView2);


                switch(position){

                case 1 : image.setImageResource(R.drawable.ic_title1);
                    break;

                case 2 : image.setImageResource(R.drawable.ic_title2);
                    break;
            }

            ImageButton deleteSession = (ImageButton) rowView.findViewById(R.id.session_item_del);
            deleteSession.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    /*if (!startStopToggle.isChecked()) {*/
                    sessionAdapter.remove(values.get(position));
                    sessionAdapter.notifyDataSetChanged();


                }
            });

            return rowView;
        }

        //in your adapter getAllPlayers() would be something like this
        public List<String> getAllPlayers() {
            List<String> list = new ArrayList<String>();
            for (Map item : values) {
                int beepStringId = context.getResources().getIdentifier("exercise_typ_"
                        + item.get("type"), "string", context.getPackageName());
                String str = context.getResources().getString(beepStringId);
                list.add(str);
            }
            return list;
        }


    }

我的切换语句试图将其与位置但只设置的ImageView 到 RowItem 是上的位置多数民众赞成写在情况。

I tried it with the Switch statement with position but that only set the ImageView to the RowItem that is on the position thats written in the case .

推荐答案

您可以根据的文本中的switch-case 语句的TextView 像下面

You can make a switch-case statement based on the text of the TextView like below

switch(tv.getText().toString()){

                case "Title1" : image.setImageResource(R.drawable.ic_title1);
                    break;

                case "Title2" : image.setImageResource(R.drawable.ic_title2);
                    break;

                default:
                    //Default image here, if no case found
                break;
}
