如何在myAdapter中的AlertDialog中創建的ImageView中設置圖像？我使用基本適配器

我在我的（主要活動）中創建了一個按鈕（1）當我點擊按鈕（1）時會發生什麼，它將顯示包含自定義ListView的AlertDialog（1）。在該自定義ListView中有一個按鈕，單擊它時也會顯示一個AlertDialog（2），它包含一個ImageView（可點擊）。我想要做的是如何設置圖像到我的ImageView。這裏是我的代碼：如何在myAdapter中的AlertDialog中創建的ImageView中設置圖像？我使用基本適配器

MainActivity.java - 這是我的按鈕（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的OnClick - 這是我如何填充ListView在我的AlertDialog（1）。

@Override

    //View v = View.inflate(mContext, R.layout.sales_invoice_custom,null);
