滚动时listview行内的textview文本颜色会发生变化

Question

我有一个listview,它是通过自定义cursoradapter生成的

一切正常,除非我在列表中上下滚动,一些textview随机变为绿色.

继承我生成列表视图的代码:

private class AchievementAdapter extends CursorAdapter {
    public AchievementAdapter(Context context, Cursor c) {
        super(context, c);
    }

    @Override
    public void bindView(View v, Context context, Cursor cursor) {
        TextView tv = (TextView) v.findViewById(R.id.achView1);

        if(cursor.getString(cursor.getColumnIndex("completed")).equals("yes")) {
            tv.setText(cursor.getString(cursor.getColumnIndex("name"))+" (completed)");
            tv.setTextColor(Color.GREEN);
        }
        else {
            tv.setText(cursor.getString(cursor.getColumnIndex("name")));
        }
    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(context);
        View v = inflater.inflate(R.layout.achievements_item, parent, false);
        return v;
    }
}    

我读了一些关于setcachecolorhint的内容,但该方法不适用于textview.我如何解决这个问题,以便在我滚动时随意停止更改textview颜色？

您应该在else语句中将textView颜色设置为normal,如:

@Override
public void bindView(View v, Context context, Cursor cursor) {
    TextView tv = (TextView) v.findViewById(R.id.achView1);

    if(cursor.getString(cursor.getColumnIndex("completed")).equals("yes")) {
        tv.setText(cursor.getString(cursor.getColumnIndex("name"))+" (completed)");
        tv.setTextColor(Color.GREEN);
    }
    else {
        tv.setText(cursor.getString(cursor.getColumnIndex("name")));
        tv.setTextColor(Color.BLACK); // Set your textview color as you need
    }
}

希望这可以帮助
