在我的应用程序中，我尝试open a DialogBox two Spinner custom layout，我在arraylist中定义了open dialog box。对于Spinner的项目，我定义了带有下拉项的AlertDialog.Builder rdialog = new AlertDialog.Builder(MainActivity.this);
rdialog.setTitle("Flavours");
rdialog.setIcon(android.R.drawable.ic_input_get);
LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
alertView = inflater.inflate(R.layout.rptsetting,null);
Spinner fSpinner = (Spinner)findViewById(R.id.fSpinner);
ArrayList<String> arrayList1 = new ArrayList<String>();
arrayList1.add("Chocolate");
arrayList1.add("vanila");
ArrayAdapter<String> adp = new ArrayAdapter<String> (MainActivity.this,android.R.layout.simple_spinner_dropdown_item,arrayList1);
fSpinner.setAdapter(adp);
fSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
Spinner phSpinner = (Spinner)findViewById(R.id.phSpinner);
ArrayList<String> arrayList2 = new ArrayList<String>();
arrayList2.add("9991734971");
ArrayAdapter<String> adp1 = new ArrayAdapter<String> (MainActivity.this, android.R.layout.simple_spinner_dropdown_item,arrayList2);
phSpinner.setAdapter(adp1);
phSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
EditText phNumber = (EditText)findViewById(R.id.phNumber);
rdialog.setView(alertView);
rdialog.setNeutralButton("SUBMIT", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
AlertDialog rdialog1 = rdialog.create();
rdialog1.show();
，当选择执行特定功能时。在编译期间，它显示没有错误，但在尝试{{1}}应用程序崩溃时。
代码：
{{1}}

你应该替换这个
Spinner fSpinner = (Spinner)findViewById(R.id.fSpinner);
Spinner phSpinner = (Spinner)findViewById(R.id.phSpinner);
使用
Spinner fSpinner = (Spinner)alertView.findViewById(R.id.fSpinner);
Spinner phSpinner = (Spinner)alertView.findViewById(R.id.phSpinner);
如果EditText来自您的Custom Dialog layout，那么也会更改
EditText phNumber = (EditText)alertView.findViewById(R.id.phNumber);
