我有一個問題,當我去下一個活動,並通過數據意圖時,它只顯示我關閉數據庫的最後一項,而不是點擊的項目信息。意圖數據沒有顯示正確
的.java
public class TimsFavs extends ListActivity implements OnItemClickListener {
/** Called when the activity is first created. */
ArrayList<String> results = new ArrayList<String>();
// Database results
String col0,col1,col2,col3,col4,col5,col6,col7;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.timsfavs);
DBAdapter db = new DBAdapter(this);
//---get all Locations---
db.open();
Cursor c = db.getAllLocation();
if (c.moveToFirst())
{
do {
col0 = c.getString(c.getColumnIndex(DBAdapter.KEY_ROWID));
col1 = c.getString(1);
col2 = c.getString(2);
col3 = c.getString(3);
col4 = c.getString(4);
col5 = c.getString(5);
col6 = c.getString(6);
col7 = c.getString(7);
results.add(col0);
} while (c.moveToNext());
}
db.close();
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,results));
ListView lv;
lv = getListView();
lv.setTextFilterEnabled(true);
lv.setBackgroundColor(Color.rgb(83, 05, 14));
lv.setOnItemClickListener((OnItemClickListener) this);
}
public void onItemClick(AdapterView<?> TimsFavs, View view, int position, long id) {
Intent i = new Intent(getApplicationContext(), TimsFavsMore.class);
i.putExtra("ct_id_pass", col0);
i.putExtra("ct_storeid_pass", col1);
i.putExtra("ct_address_pass", col2);
i.putExtra("ct_city_pass", col3);
i.putExtra("ct_province_pass", col4);
i.putExtra("ct_country_pass", col5);
i.putExtra("ct_pcode_pass", col6);
i.putExtra("ct_phnum_pass", col7);
startActivity(i);
finish();
}
}
和我的其他活動是
`公共類TimsFavsMore延伸活動{ 將對DBAdapter分貝=新將對DBAdapter(本);
String rowId;
@Override
public void onCreate(Bundle savedInstanceState) {

button3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//---add 2 SQLite---
db.open();
if (db.deleteLocation(rowId))
Toast.makeText(getApplicationContext(), " Delete successful.",

else

}
}`
什麼想法?
是的,你現在我只需要找出它的編碼感謝您採取的方向。 – PsychoDogg 2011-04-10 17:10:55
看看記事本示例 - 它有一個簡單的列表視圖綁定到一個遊標,並應爲您提供一個很好的啓動點。 http://www.google.com/url?sa=t&source=web&cd=1&sqi=2&ved=0CBsQFjAA&url=http%3A%2F%2Fdeveloper.android.com%2Fresources%2Ftutorials%2Fnotepad%2F&rct=j&q=android%20notepad% 20example&ei = wEeiTfOgB5T2gAfz8tnaBQ&usg = AFQjCNGqDN3kFwMcsPBsIQbCFK69WM1cQg&cad = rja – jkhouw1 2011-04-11 00:14:12
我看了記事本,並且無法制作它的正面或反面。 – PsychoDogg 2011-04-14 03:21:30
