问题描述

当使用SimpleCursorAdaptor显示它如何改变项目的文本的ListView?
这里是我的code。

How to change text of items in ListView when it is displayed using SimpleCursorAdaptor?Here is my code.

Cursor allTaskcursor = databaseHelper.getAllTasks();
String[] from = {"name", "date"};
int[] to = new int[] {android.R.id.text1, android.R.id.text2};
SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(context, android.R.layout.simple_list_item_2, allTaskcursor, from, to, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
allTaskListView.setAdapter(cursorAdapter);

getAllTask​​s(),它显示在的 android.R.id.text2 的返回游标其中date是一个整数值(例如10)。我想改变的文本(例如10日)。

getAllTasks() returns a cursor where date is an Integer value (example 10) which is displayed in android.R.id.text2. I want to change that text (example "10 days").

SimpleCursorAdapter.ViewBinder did the job. As answered here, I changed the code to..

Cursor allTaskcursor = databaseHelper.getAllTasks();
    String[] from = {"name", "date"};
    int[] to = new int[] {android.R.id.text1, android.R.id.text2};
    SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(context, android.R.layout.simple_list_item_2, allTaskcursor, from, to, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
    cursorAdapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
        @Override
        public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
            if (view.getId() == android.R.id.text2) {
                int getIndex = cursor.getColumnIndex("date");
                int date = cursor.getInt(getIndex);
                TextView dateTextView = (TextView) view;
                dateTextView.setText(date + " days");
                return true;
            }
            return false;
        }
    });
    allTaskListView.setAdapter(cursorAdapter);
