Question

我有一个ListView，每个项目包含TextView和ProgressBar，使用自定义Adapter填充，如下所示：

String[] actions = new String[] {
        "Stretch", "Walk",
        "Drink water", "Eat fruit(s)" };

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    final RoutineArrayAdapter arrayAdapter = 
            new RoutineArrayAdapter(getActivity(), actions);
    setListAdapter(arrayAdapter);     
}

public class RoutineArrayAdapter extends ArrayAdapter<String> {
    private final Context context;
    private final String[] values;

    public RoutineArrayAdapter(Context context, String[] values) {
        super(context, -1, values);
        this.context = context;
        this.values = values;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.routine_list_layout, parent, false);
        TextView textView = (TextView) rowView.findViewById(R.id.action);
        textView.setText(values[position]);

        return rowView;
    }
}

但每个ProgressBar会有所不同，具体取决于与之关联的文字。

如何以编程方式单独修改每个ProgressBar（大小，颜色，进度值等）？

Answer 1

 ProgressBar progressBar = (ProgressBar) rowView.findViewById(R.id.progress_bar);

您可以在getView（..）中获取此progressBar，就像访问textview

一样

单独修改ListView中的ProgressBars
