step1 创建窗体

final AlertDialog dialog =new Builder(this).create();

step2 获取View

View viewDialog =View.inflate(this, R.layout.userinfo_dialog_edit, null);            final EditText txtUserName=(EditText)viewDialog.findViewById(R.id.txtUserName);            final EditText txtBirthday=(EditText)viewDialog.findViewById(R.id.txtBirthday);            final EditText txtPhoneNumber=(EditText)viewDialog.findViewById(R.id.txtPhoneNumber);            final EditText txtAddress=(EditText)viewDialog.findViewById(R.id.txtAddress);            txtUserName.setText(userDto.getUserName());            txtBirthday.setText(userDto.getBirthday());            txtPhoneNumber.setText(userDto.getPhoneNumber());            txtAddress.setText(userDto.getAddress());            Button btnSave =(Button)viewDialog.findViewById(R.id.btnSave);            Button btnClose =(Button)viewDialog.findViewById(R.id.btnClose);            btnSave.setOnClickListener(new OnClickListener(){                @Override                public void onClick(View arg0) {                    UserInfoDto dto =new UserInfoDto();                    dto.setUserName(txtUserName.getText().toString());                    dto.setBirthday(txtBirthday.getText().toString());                    dto.setPhoneNumber(txtPhoneNumber.getText().toString());                    dto.setAddress(txtAddress.getText().toString());                    InsertOneTest(dto);                }            });            btnClose.setOnClickListener(new OnClickListener(){                @Override                public void onClick(View arg0) {                    dialog.dismiss();                }            });

step3 show窗体

dialog.setView(viewDialog, 0, 0, 0, 0);

dialog.show();
