我在我的（主要活动）中创建了一个Button（1）当我点击按钮（1）时它会显示一个包含自定义ListView的AlertDialog（1）。在那个Custom ListView中有一个Button，当点击它时它也会显示一个AlertDialog（2），它包含一个ImageView（Clickable）。我要做的是如何将图像设置为我的ImageView。这是我的代码：
MainActivity.java - 这是按钮的OnClick（1）
public void PayInvoice(View view){
String minAmount = null;
myDbHelper = new DBHelper(this);
try {
myDbHelper.createDataBase();
myDbHelper.openDataBase();
CustomerID = "1600050";
minAmount = myDbHelper.getMinAmountDue(CustomerID);
} catch (Exception e) {
e.getMessage();
}
myDbHelper.close();
if (TotalAmountET.getText().equals("") || TotalAmountET.getText().length() == 0) {
Toast.makeText(this, "PUT PAYMENT AMOUNT FIRST...", Toast.LENGTH_SHORT).show();
} else if (Float.parseFloat(minAmount) > Float.parseFloat(TotalAmountET.getText().toString()) ) {
Toast.makeText(this, "TOTAL AMOUNT IS NOT ENOUGH...", Toast.LENGTH_SHORT).show();
} else {
AlertDialog.Builder alertdialogbuilder = new AlertDialog.Builder(PaymentHeader.this);
LayoutInflater inflater = getLayoutInflater();
View alertLayout = inflater.inflate(R.layout.sales_invoice_list, null);
alertdialogbuilder.setView(alertLayout);
final ListView SalesInvoiceList = (ListView) alertLayout.findViewById(R.id.invoiceList);
final Button Cancel = (Button) alertLayout.findViewById(R.id.cancelBTN);
final Button PayInvoice = (Button) alertLayout.findViewById(R.id.payinvoiceBTN);
final AlertDialog alertDialog = alertdialogbuilder.create();
alertDialog.setCanceledOnTouchOutside(false);
alertDialog.show();
myDbHelper = new DBHelper(this);
try {
myDbHelper.createDataBase();
myDbHelper.openDataBase();
CustomerID = "1600050";
try {
invoiceLists = myDbHelper.retrieveInvoices(CustomerID);
customListView_invoiceList = new CustomListView_InvoiceList
(this, invoiceLists,Float.parseFloat(TotalAmountET.getText().toString()));
SalesInvoiceList.setAdapter(customListView_invoiceList);
} catch (Exception e) {
e.getMessage();
}
} catch (Exception e) {
e.getMessage();
}
Cancel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
alertDialog.dismiss();
}
});
PayInvoice.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
insertPaymentLine();
}
});
}
}
CustomListView_InvoiceList.java - 这是我如何在AlertDialog（1）中填充ListView。

根据您的要求创建自定义对话框类和实现接口，请遵循此示例对话框类代码
public class AddFlightDialog extends Dialog {
@Bind(R.id.edtTxtflightnumber)
EditText edtTxtflightnumber;
@Bind(R.id.btnAddComment)
Button btnAddComment;
@Bind(R.id.btnCancelComment)
Button btnCancelComment;
private Context mContext;
FlightNumberListner flightNumberListner;
@OnClick(R.id.btnAddComment)
void btnAddComment() {
flightNumberListner.addflightnumber(edtTxtflightnumber.getText().toString());
dismiss();
}
@OnClick(R.id.btnCancelComment)
void closeDialog() {
flightNumberListner.noflightNumber();
dismiss();
}
String comment = "";
public AddFlightDialog(String comment, Context context, FlightNumberListner flightNumberListner) {
super(context, R.style.Theme_Custom);
this.flightNumberListner = flightNumberListner;
this.comment = comment;
this.mContext = context;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dialog_add_flight);
ButterKnife.bind(CustomDialog.this);
}
public interface FlightNumberListner {
public void addflightnumber(String flightnum);
public void noflightNumber();
}
}
对话调用方法
new AddFlightDialog(comment, getActivity(), new AddFlightDialog.FlightNumberListner() {
@Override
public void addflightnumber(String flightnum) {
//your code
}
@Override
public void noflightNumber() {
//your code
}
}).show();
