ここにヘッドスクラッチャーがあります...（少なくとも私にとっては）私のデータベースからの連絡先のリストを表示する連絡先リストがあります。ユーザーが連絡先の 1 つをクリックすると、編集アクティビティが表示されます。現在のレイアウトどおりにすべてが完全に機能しますが、編集アクティビティで名の前に姓のエントリを表示する必要があります。すべてのフィールドが 1 対 1 の関係を持つ必要があると考えて、先に進み、編集アクティビティで姓の editText(XML) を名の上に移動しました。これは EditText の ID で参照する必要があると考えました。その後、プログラムは姓フィールドに名を表示し、その逆も同様です。エミュレーターでユーザーデータを消去してみましたが、違いはありません。私はすでにこれがおそらくそれらの 1 つであることを理解しています。質問を入力しますが、誰かが私にとって明白なことを指摘できる場合は、それはありがたいです。表示されているすべてのコードは、現在動作中の状態です。
私の問題とは関係のないチャンクをいくつか削除しました。私のためにこれを見てくれた人に感謝します！ケン
XML:
<EditText
android:id="@+id/contact_edit_first_name"
android:inputType="textPersonName"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:hint="@string/contact_edit_first_name"
android:imeOptions="actionNext"
android:background="@color/warn" >
</EditText>
<EditText
android:id="@+id/contact_edit_last_name"
android:inputType="textPersonName"
android:layout_width="fill_parent"

</EditText>
これは、listView 行を表示し、行を追加、編集、または削除するインテントを送信する createContact を呼び出す contact アクティビティです。
public class ContactsActivity extends ListActivity implements
LoaderManager.LoaderCallbacks<Cursor> {
private SimpleCursorAdapter adapter;
/** Called when the activity is first created. */
@Override
public void onCreate //DO THE ON CREATE STUFF -removed
fillData();
registerForContextMenu(getListView());
Button add_contact = (Button) findViewById(R.id.add_contact_button);
add_contact.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
createContact();
}
});
}
// Create the options menu to INSERT from the XML file
// removed - not relevant
// return true for the menu to be displayed
}
// When the insert menu item is selected, call CreateContact
//Removed
createContact();
return true;
}
return super.onOptionsItemSelected(item);
}
private void createContact() {
Intent i = new Intent(this, ContactEditActivity.class);
startActivity(i);
}
//The onListItemClick sends a URI which flags the contactEditActivity
//that this is an edit rather than a new insert.
@Override
protected void onResume() {
super.onResume();
//Starts a new or restarts an existing Loader in this manager
getLoaderManager().restartLoader(0, null, this);
}
//The fillData method binds the simpleCursorAadapter to the listView.
private void fillData() {
//The desired columns to be bound:
String[] from = new String[] { ContactsDB.COLUMN_LAST_NAME, ContactsDB.COLUMN_FIRST_NAME };
//The XML views that the data will be bound to:
int[] to = new int[] {R.id.label2, R.id.label};
// The creation of a loader using the initLoader method call.
getLoaderManager().initLoader(0, null, this);
adapter = new SimpleCursorAdapter(this, R.layout.contact_row, null, from,
to, 0);
setListAdapter(adapter);
}
// Sort the names by last name, then by first name
String orderBy = ContactsDB.COLUMN_LAST_NAME + " COLLATE NOCASE ASC"
+ "," + ContactsDB.COLUMN_FIRST_NAME + " COLLATE NOCASE ASC" ;
// Creates a new loader after the initLoader () call
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
//ETC
}
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
adapter.swapCursor(data); //Call requires Min API 11
}
@Override
public void onLoaderReset(Loader<Cursor> loader) {
// swap the cursor adapter
}
そして最後に、これはおそらく私の悲しみの原因である連絡先編集コードです...おそらくそうではありません。保存状態がIDにマップされていない可能性がありますか?
