我想我在这里做了一些非常基本的错误。我无法编辑由我的列表适配器生成的任何editText字段（文本框显示，我可以将光标放在字段上，但我无法键入/删除任何文本）。这是我的代码。此ListAdapter编辑文本有什么问题？
我ListAdaptor 公共类LoanRepaymentListAdapter扩展ArrayAdapter {
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) {
String repaymentAmount = arg0.toString();
loansForRepayment.get(position).setRepaymentAmount(Float.parseFloat(repaymentAmount));
}
@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) {
// TODO Auto-generated method stub
}
});
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;
}
}
我的XML loan_repayments
<TextView android:id="@+id/screenTitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</TextView>
<ListView

</RelativeLayout>
我的活动代码
public void onCreate(Bundle savedInstanceState){
lastKnownLocation = Utility.getLastKnownLocation(this);
super.onCreate(savedInstanceState);
Intent intent = getIntent();
loansForRepayment = (ArrayList<CurrentRepaymentInstallment>)intent.getSerializableExtra(Constants.CURRENT_REPAYMENT_INSTALLMENT);
ArrayAdapter<CurrentRepaymentInstallment> adapter = new LoanRepaymentListAdapter(this, loansForRepayment);
View footer = getLayoutInflater().inflate(R.layout.loan_disbursement_footer, null);
getListView().addFooterView(footer);
setListAdapter(adapter);
Button button = (Button)findViewById(R.id.disburse);
button.setOnClickListener(this);
}
也想知道我如何在我的列表onChange中设置编辑的文本的值。谢谢
这不是一个代码问题。问题是，当我选择editText时，键盘弹出在我的模拟器上，并取消选择editText。这是因为我在模拟器上执行它还是有办法严格控制它？ –
@Arvind Sridharan：对不起，我不能说出是什么原因，你需要在真实的设备上试用它。 –
会在真实设备上试用并回复。 –
