如何使用微调器制作警报对话框[关闭]

Question

我知道如何制作警报对话框，但我需要使用微调器制作一个，这样当它弹出时，人们可以选择发生什么。有没有人知道带有微调器的警报对话框的代码或知道任何好的教程？

提前致谢

Answer 1

LayoutInflater li = LayoutInflater.from(context);

View promptsView = li.inflate(R.layout.my_dialog_layout, null);

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);

alertDialogBuilder.setView(promptsView);

// set dialog message

alertDialogBuilder.setTitle("My Dialog..");
alertDialogBuilder.setIcon(R.drawable.ic_launcher);
// create alert dialog
final AlertDialog alertDialog = alertDialogBuilder.create();

final Spinner mSpinner= (Spinner) promptsView
        .findViewById(R.id.mySpinner);
final Button mButton = (Button) promptsView
        .findViewById(R.id.myButton);

// reference UI elements from my_dialog_layout in similar fashion

mSpinner.setOnItemSelectedListener(new OnSpinnerItemClicked());

// show it
alertDialog.show();
alertDialog.setCanceledOnTouchOutside(false);

在哪里

my_dialog_layout 是包含 Spinner mySpinner

的弹出式布局

编辑：

public class OnSpinnerItemClicked implements OnItemSelectedListener {

        @Override
        public void onItemSelected(AdapterView<?> parent,
                View view, int pos, long id) {
            Toast.makeText(parent.getContext(), "Clicked : " +
                    parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();


        }

        @Override
        public void onNothingSelected(AdapterView parent) {
            // Do nothing.
        }
    }
