這是AccountListView,它檢索並顯示我已經添加到數據庫中的數據在列表視圖中,我添加了現金和銀行帳戶,當我點擊列表視圖中的現金時它打開交易意圖,其中有一個微調現金和銀行已被添加,我希望它顯示我點擊列表視圖的數據。請注意,現金和銀行顯示餘額只能用於微調。在Spinner上設置文本
public class AccountListActivity extends Activity implements OnClickListener, OnItemClickListener {

當交易的意圖是開放它採取使用以下代碼紡絲器的 Transaction.java
public class Transaction extends Activity implements OnClickListener{
private Spinner Category, Account, typerp;
private TextView tvSaveNew, tvDisplayDate;
private EditText ItemName, Amount, Notes;
private EditText Balance, Result;
private ImageButton TransDate, ImageButton1;
private Button save, newt;
private String bundledBankName;
private String bundledBankType;
private String bundledBankNumber;
private String bundledBankBalance;
private String bundledBankDate;
private String BankNameValue;
private String NewBankBalanceValue;
private String BankTypeValue;
private String BankNumberValue;
private String BankBalanceValue;
private String BankDateValue;
private int year;
private int month;
private int day;
static final int DATE_DIALOG_ID = 999;
private ArrayList<TransactionDetails> TransactionDetailsObjArrayList;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.transaction);
save = (Button) findViewById(R.id.TbtnSave);
newt = (Button) findViewById(R.id.btnNewTran);
TransDate = (ImageButton) findViewById(R.id.transDate);

Account = (Spinner) findViewById(R.id.TAccount);
typerp = (Spinner) findViewById(R.id.TypeR);

Amount = (EditText) findViewById(R.id.TransAmount);
Notes = (EditText) findViewById(R.id.tranNote);
Balance = (EditText) findViewById(R.id.RetrieveBalance);
Result = (EditText) findViewById(R.id.ResultBalance);
tvDisplayDate = (TextView) findViewById(R.id.ttvDisplayDate);
save.setOnClickListener(this);
newt.setOnClickListener(this);
setCurrentDateOnView();
TransDate.setOnClickListener(this);
TransactionDetailsObjArrayList = new ArrayList<TransactionDetails>();
loadSpinnerData();
Bundle takeBundledData = getIntent().getExtras();
bundledBankName = takeBundledData.getString("clickedBankName");
bundledBankBalance = takeBundledData.getString("clickedBankBalance");

}
首先了解微調http://developer.android.com/guide/topics/ui/controls/spinner.html –
紗廠是由處理數據的列表/顯示什麼當前被選中。這與僅僅設置文本不同。 – Shellum
在陣列的第一個「第0個」位置添加您的「標題」,並將該陣列設置爲您的微調器。 – MKJParekh
