我想實現一個帶有標題的ListView。但是,使用下面的代碼,會發生以下情況:如何使用ListView在我的佈局中設置標題?

標題顯示在第一個列表元素上。 有一個EditText出現在頂部其他人的前面。

我的Android活動

public class LoanRepaymentActivity extends ListActivity implements View.OnClickListener { 

private Location lastKnownLocation; 
private ArrayList<CurrentRepaymentInstallment> loansForRepayment; 
@Override 
public void onCreate(Bundle savedInstanceState){ 
    lastKnownLocation = Utility.getLastKnownLocation(this); 
    super.onCreate(savedInstanceState); 

    Intent intent = getIntent(); 

    RepaymentInfo repaymentInfo = (RepaymentInfo)intent.getSerializableExtra(Constants.CURRENT_REPAYMENT_INSTALLMENT); 
    loansForRepayment = repaymentInfo.getLoansForRepayment(); 
    boolean repaymentsNotPresent = loansForRepayment == null || loansForRepayment.isEmpty(); 
    if(repaymentsNotPresent){ 
     Dialog dialog = Utility.getDialogWithText(LoanRepaymentActivity.this, getText(R.string.noLoansForRepayment).toString()); 
     Utility.getDialogButton(dialog, LoanRepaymentActivity.this, PartnerGroupListActivity.class, intent.getStringExtra(Constants.ACECSS_TOKEN_PARAM)); 
     dialog.show(); 
    } 

    setContentView(R.layout.loan_repayments); 

    ArrayAdapter<CurrentRepaymentInstallment> adapter = new LoanRepaymentListAdapter(this, loansForRepayment); 

    View footer = getLayoutInflater().inflate(R.layout.loan_disbursement_footer, null); 
    getListView().addFooterView(footer); 

    setListAdapter(adapter); 
     if(!repaymentsNotPresent) { 
     TextView textView = (TextView)findViewById(R.id.screenTitle); 
     String currentInstallmentLabel = getText(R.string.currentInstallmentLabel).toString() + repaymentInfo.getCurrentGroupInstallment(); 
     textView.setText(currentInstallmentLabel); 
    } 

    Button button = (Button)findViewById(R.id.disburse); 
    button.setOnClickListener(this); 
} 

的XML

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:orientation="vertical" 
> 

<TextView android:id="@+id/screenTitle" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" > 
</TextView> 

<ListView 
    android:id="@android:id/list" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_above="@+layout/loan_disbursement_footer" 
    /> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:orientation="vertical" > 
<TextView 
    android:id="@+id/borrowerName" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@+id/label" 
    android:textSize="14sp" 
    > 
</TextView> 

<TextView 
    android:id="@+id/loanAmount" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@+id/label" 
    android:textSize="14sp" 
    > 
</TextView> 

<TextView 
    android:id="@+id/installmentNumber" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@+id/label" 
    android:textSize="12sp" 
    > 
</TextView> 

<TextView 
    android:id="@+id/estimatedTotal" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@+id/label" 
    android:textSize="12sp" 
    > 
</TextView> 

</LinearLayout> 
<EditText 
    android:id="@+id/repaymentAmount" 
    android:layout_width="100sp" 
    android:layout_height="wrap_content" 
    android:layout_alignParentRight="true" 
    android:inputType="numberDecimal" 
    android:textSize="12sp" 
    > 
</EditText> 

自定義數組適配器

public class LoanRepaymentListAdapter extends ArrayAdapter<CurrentRepaymentInstallment> { 

private final List<CurrentRepaymentInstallment> loansForRepayment; 
private final Activity context; 

public LoanRepaymentListAdapter(Activity context, List<CurrentRepaymentInstallment> loansForRepayment) { 
    super(context, R.layout.loan_repayments, loansForRepayment); 
    this.context = context; 
    this.loansForRepayment = loansForRepayment; 
} 

static class ViewHolder { 
    protected TextView borrowerName; 
    protected TextView loanAmount; 
    protected TextView installmentNumber; 
    protected TextView estimatedTotal; 
    protected EditText repaymentAmount; 
} 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    View view = null; 
    if (convertView == null) { 
     LayoutInflater inflator = context.getLayoutInflater(); 
     view = inflator.inflate(R.layout.loan_repayments, null); 
     final ViewHolder viewHolder = new ViewHolder(); 
     viewHolder.borrowerName = (TextView) view.findViewById(R.id.borrowerName); 
     viewHolder.loanAmount = (TextView) view.findViewById(R.id.loanAmount); 
     viewHolder.installmentNumber = (TextView) view.findViewById(R.id.installmentNumber); 
     viewHolder.estimatedTotal = (TextView) view.findViewById(R.id.estimatedTotal); 
     viewHolder.repaymentAmount = (EditText) view.findViewById(R.id.repaymentAmount); 
//   viewHolder.repaymentAmount.setEditableFactory(Editable.Factory.getInstance()); 
     viewHolder.repaymentAmount.addTextChangedListener(new TextWatcher() { 

      @Override 
      public void afterTextChanged(Editable arg0) { 

      } 

      @Override 
      public void beforeTextChanged(CharSequence s, int start, 
        int count, int after) { 
       // TODO Auto-generated method stub 

      } 

      @Override 
      public void onTextChanged(CharSequence s, int start, int before, int count) { 
       String repaymentAmount = s.toString(); 
       try { 
        loansForRepayment.get(position).setRepaymentAmount(Float.parseFloat(repaymentAmount)); 
       } catch (Exception ex){ 
        loansForRepayment.get(position).setRepaymentAmount(0.0F); 
       } 
      } 


     }); 
     view.setTag(viewHolder); 
     viewHolder.repaymentAmount.setTag(loansForRepayment.get(position)); 
    } else { 
     view = convertView; 
     ((ViewHolder) view.getTag()).repaymentAmount.setTag(loansForRepayment.get(position)); 
    } 
    ViewHolder holder = (ViewHolder) view.getTag(); 
    holder.borrowerName.setText(loansForRepayment.get(position).getLoanProfileBasicInfo().getBorrowerBasicInfo().getFirstName()); 
    holder.loanAmount.setText("Rs. " + Float.toString(loansForRepayment.get(position).getLoanProfileBasicInfo().getLoanAmountInPaisa()/100)); 
    holder.estimatedTotal.setText("Rs. " + Float.toString(loansForRepayment.get(position).getEstimatedTotalAmount()/100)); 
    holder.installmentNumber.setText("Inst no : " + Integer.toString(loansForRepayment.get(position).getInstallmentNumber())); 
    float repaymentAmt = loansForRepayment.get(position).getRepaymentAmount(); 
    if(repaymentAmt != 0.0) holder.repaymentAmount.setText(Float.toString(repaymentAmt)); 
    return view; 
     } 
    } 

將是巨大的,如果有人能告訴我如何做到這一點。

爲標題設置一個新佈局,並將其作爲標題添加到ListView中。

XML

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_alignParentBottom="true" 
    > 

<TextView android:id="@+id/repaymentScreenTitle" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/repaymentsTitle" > 
</TextView> 
</LinearLayout> 

在活動替換它下面的一個此塊

 if(!repaymentsNotPresent) { 
    TextView textView = (TextView)findViewById(R.id.screenTitle); 
    String currentInstallmentLabel = getText(R.string.currentInstallmentLabel).toString() + repaymentInfo.getCurrentGroupInstallment(); 
    textView.setText(currentInstallmentLabel); 
} 

    View headerView = getLayoutInflater().inflate(R.layout.loan_repayment_title, null); 
    TextView titleView = (TextView) headerView.findViewById(R.id.repaymentScreenTitle); 
    String titlePrefix = (String) getText(R.string.groupInstallmentLabel); 
    titleView.setText(titlePrefix + " " + repaymentInfo.getCurrentGroupInstallment()); 
    getListView().addHeaderView(headerView);
