Java 自定义对话框有问题

我需要一些有关自定义对话框的帮助。这是我第一次构建自定义对话框，但由于某些原因，它一直崩溃。下面的代码是我的onCreate方法中的代码。我想点击编辑文本框，弹出对话框，然后输入股票代码或股票价格，点击确定，它将填充编辑文本框。请帮忙

public void test() {
    // Click on Stock Price to bring up dialog box
    myStockPrice.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            // Create the dialog
            final Dialog dialog = new Dialog(
                    OptionsPricingCalculatorActivity.this);

            // Set the content view to our xml layout
            dialog.setContentView(R.layout.enterstocksym);

            // Set the title of the dialog. this space is always drawn even
            // if blank so might as well use it
            dialog.setTitle("Ticker Symbol");

            dialog.setCancelable(true);
            // dialog.setMessage("Enter Company Ticker Symbol");

            // Here we add functionality to our dialog box's content. In
            // this example it's the two buttons

            // Set an EditText view to get user input
            input = (EditText) findViewById(R.id.StockSymbol);
            input2 = (EditText) findViewById(R.id.StockPrice);

            Button okButton = (Button) dialog.findViewById(R.id.BtnOk);

            okButton.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    Tickervalue = input.getEditableText().toString().trim();
                    // Do something with value!

                    // Toast.makeText(getApplicationContext(), value,
                    // Toast.LENGTH_SHORT).show();
                    // Send Stock Symbol into Request
                    SoapObject request = new SoapObject(NAMESPACE,
                            METHOD_NAME);
                    request.addProperty("symbol", Tickervalue);

                            SoapEnvelope.VER11);
                    envelope.setOutputSoapObject(request);
                    envelope.dotNet = true;
                    HttpTransportSE httpTransport = new HttpTransportSE(
                            SERVICE_URL);
                    // httpTransport.debug = true;
                    try {
                        httpTransport.call(SOAP_ACTION, envelope);
                        SoapPrimitive result = (SoapPrimitive) envelope

使用嵌套的匿名内部类很难判断，但我认为您的带有ids StockSymbol和StockPrice的小部件在对话框中。当您找到它们时，您可以这样做：

input = (EditText)findViewById(R.id.StockSymbol);       
input2 = (EditText)findViewById(R.id.StockPrice);

在活动中而不是在对话框中查看。未找到它们，因此单击按钮时输入为空。请尝试以下方法：

input = (EditText)dialog.findViewById(R.id.StockSymbol);       
input2 = (EditText)dialog.findViewById(R.id.StockPrice);

您可能希望将内部类拆分，以使所有这些内容更易于阅读和调试。

下面的代码非常有用，但是我希望自定义布局能够正常工作

谢谢

LinearLayout lila1= new LinearLayout(this);
lila1.setOrientation(1); //1 is for vertical orientation
final EditText input = new EditText(this); 
final EditText input1 = new EditText(this);
lila1.addView(input);
lila1.addView(input1);
alert.setView(lila1);
