我如何在android中设置微调器内的警告对话框？
我正在制作listview，如果您点击任何项目，则应显示alertbox。在alertBox中有微调器，按钮edittext等。我想要在alertbox内部制作微调器，但是我无法为这种情况编写正确的代码。我listitem也来自json.Now请帮我把微调器放在警告对话框中？
这是我的SubMenu活动：
public class SubMenu extends AppCompatActivity {
JSONObject jsonobject;

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// Get the view from listview_main.xml

使用spinner，button edittext等创建布局，并在对话框视图中将此布局设置为： -
Dialog dialog = new Dialog(AddCardScreen.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.alert_dialog);
Button dialogButton = (Button) dialog.findViewById(R.id.btn_ok);
TextView tv_status = (TextView) dialog.findViewById(R.id.tv_status);
dialog.show();
