以下是我的代碼:安卓:ListView的onItemClick()事件沒有得到所謂的
public class TestActivity extends ListActivity {
private Cursor cursor;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
fillData();
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
// Get the item that was clicked
Object o = this.getListAdapter().getItem(position);
String keyword = o.toString();
Toast.makeText(this, "You selected: " + keyword, Toast.LENGTH_LONG)
.show();
}
private void fillData() {
TermsData_DataHelper termsDataHelper = new TermsData_DataHelper(
TestActivity.this);
cursor = termsDataHelper.fetchAllCategories();
startManagingCursor(cursor);
String[] names = new String[] { "name" };
int[] to = new int[] { R.id.label };
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter categories = new SimpleCursorAdapter(this,
R.layout.terms_row, cursor, names, to);
setListAdapter(categories);
}
}
當我在ListView點擊一排,我看不出有任何吐司。有人可以告訴我我在哪裏犯了一個錯誤。
在此先感謝。
別人可能會轉起來很快解決這個問題,而只是提的是:放置一個斷點'onListItemClick()'和運行在調試模式將允許您以確保方法是否被稱爲所有,這可能會縮小可能出現的問題的範圍。 – 2011-05-25 17:27:34
@Viking:我在'onListItemClick()'處添加了一個斷點,我發現當我單擊列表視圖行時,控件不會到達那裏。可以告訴我可能有什麼錯誤? – 2011-05-25 17:35:28
