我有一个使用自定义cursoradaptor的sqldatabase列表视图。我想回到我在ListView中单击项时用来创建项的活动,以便编辑项。但是,当我在cursoradapter上实现onitemclick方法和getitemid()时,什么也不会发生,即使我不确定我是否正确。这是我的代码:

public void onItemClick(AdapterView<?> adapview, View view, int position, long rowId) {

        Cursor c = adapter.retrieveRow(rowId); // retrieve row from Database
            Intent edit = new Intent(this,NewItem.class);
        edit.putExtra(DBAdapter.KEY_ID, rowId);
            edit.putExtra(DBAdapter.Title, c.getString(c.getColumnIndex(DBAdapter.Title)));
      edit.putExtra(DBAdapter.DATE, c.getString(c.getColumnIndex(DBAdapter.DATE)));
            startActivity(edit);
        }

public long getItemId(int id){
            return id;
        }

最佳答案

我认为您需要在listview上设置一个onitemclicklistener,而不是尝试在adapter类中实现它。
例子:

mListView = (ListView)findViewbyId(R.id.whatever)
mListView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View view, int position,
                    long rowId) {
                Cursor c = adapter.retrieveRow(rowId); // retrieve row from Database
                Intent edit = new Intent(this,NewItem.class);
                edit.putExtra(DBAdapter.KEY_ID, rowId);
                edit.putExtra(DBAdapter.Title, c.getString(c.getColumnIndex(DBAdapter.Title)));
                edit.putExtra(DBAdapter.DATE, c.getString(c.getColumnIndex(DBAdapter.DATE)));
                startActivity(edit);
            }
        });

这就是你要做的吗?
