我想爲我的適配器設置onItemClickListener,它可以工作,但現在我不知道如何獲取點擊對象?我有一個列表與筆記,並點擊我想開始與點擊筆記ID的新活動。如何獲取來自SimpleCursorAdapter的OnItemClickListener中的數據
private DatabaseHelper dbhelper;
SimpleCursorAdapter adapter = null;
public OnItemClickListener listener = new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "it works", Toast.LENGTH_SHORT).show();
}
};
@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
setContentView(R.layout.first);
dbhelper = new DatabaseHelper(getApplicationContext());
Cursor cursor = dbhelper.getAllNotes();
startManagingCursor(cursor);
ListView lv = (ListView)findViewById(android.R.id.list);
String[] columns = new String[] {"NoteTitle", "NoteDate"};
int[] to = new int[] { R.id.title_entry, R.id.date_entry};
adapter = new SimpleCursorAdapter(this, R.layout.note_entry, cursor, columns, to);
lv.setAdapter(adapter);
lv.setOnItemClickListener(listener);
}
...
public Cursor getAllNotes()
{
SQLiteDatabase db=this.getReadableDatabase();
return db.query(noteTable, new String [] {colID, colTitle, colDesc, colDate}, null, null, null, null, null);
}
...
我應該在onItemClick中插入什麼來獲取note標識(Toast僅用於檢查它是否工作)?提前/

您能否告訴我如何在另一活動中接收意圖?我想在另一個activity的edittext中設置listview項目的內容。我已經按照你的回答,但我不知道如何在另一個活動中獲取所選項目的ID和數據庫內容。 – Apurva 2015-02-01 10:12:03
