受汤姆的回答启发，我认为这里的想法是：

在创建对话框期间将onClickListener设置为null然后在显示对话框后设置onClickListener。

您可以像Tom一样重写onShowListener。或者，您可以

调用AlertDialog的show（）后获取按钮按如下方式设置按钮的onClickListener（我认为稍微可读一些）。

代码：

AlertDialog.Builder builder = new AlertDialog.Builder(context);
// ...
final AlertDialog dialog = builder.create();
dialog.show();
// now you can override the default onClickListener
Button b = dialog.getButton(AlertDialog.BUTTON_POSITIVE);
b.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Log.i(TAG, "ok button is clicked");
        handleClick(dialog);
    }
});

超简单的Kotlin方法

 with(AlertDialog.Builder(this)) {
        setTitle("Title")
        setView(R.layout.dialog_name)
        setPositiveButton("Ok", null)
        setNegativeButton("Cancel") { _, _ -> }
        create().apply {
            setOnShowListener {
                getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener {
                    //Validate and dismiss
                    dismiss()
                }
            }
        }
    }.show()

public class ComentarDialog extends DialogFragment{
private EditText comentario;

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = LayoutInflater.from(getActivity());
    View v = inflater.inflate(R.layout.dialog_comentar, null);
    comentario = (EditText)v.findViewById(R.id.etxt_comentar_dialog);

    builder.setTitle("Comentar")
           .setView(v)
           .setPositiveButton("OK", null)
           .setNegativeButton("CANCELAR", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int id) {

               }
           });

    return builder.create();
}

@Override
public void onStart() {
    super.onStart();

    //Obtenemos el AlertDialog
    AlertDialog dialog = (AlertDialog)getDialog();

    dialog.setCanceledOnTouchOutside(false);
    dialog.setCancelable(false);//Al presionar atras no desaparece

    //Implementamos el listener del boton OK para mostrar el toast
    dialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if(TextUtils.isEmpty(comentario.getText())){
               Toast.makeText(getActivity(), "Ingrese un comentario", Toast.LENGTH_SHORT).show();
               return;
            }
            else{
                ((AlertDialog)getDialog()).dismiss();
            }
        }
    });

    //Personalizamos
    Resources res = getResources();

    //Buttons
    Button positive_button = dialog.getButton(DialogInterface.BUTTON_POSITIVE);
    positive_button.setBackground(res.getDrawable(R.drawable.btn_selector_dialog));

    Button negative_button =  dialog.getButton(DialogInterface.BUTTON_NEGATIVE);
    negative_button.setBackground(res.getDrawable(R.drawable.btn_selector_dialog));

    int color = Color.parseColor("#304f5a");

    //Title
    int titleId = res.getIdentifier("alertTitle", "id", "android");
    View title = dialog.findViewById(titleId);
    if (title != null) {
        ((TextView) title).setTextColor(color);
    }

    //Title divider
    int titleDividerId = res.getIdentifier("titleDivider", "id", "android");
    View titleDivider = dialog.findViewById(titleDividerId);
    if (titleDivider != null) {
        titleDivider.setBackgroundColor(res.getColor(R.color.list_menu_divider));
    }
}
}

它可以用最简单的方法构建：

带有自定义视图和两个按钮（正和负）的警报对话框。

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()).setTitle(getString(R.string.select_period));
builder.setPositiveButton(getString(R.string.ok), null);

 builder.setNegativeButton(getString(R.string.cancel), new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    // Click of Cancel Button

   }
 });

  LayoutInflater li = LayoutInflater.from(getActivity());
  View promptsView = li.inflate(R.layout.dialog_date_picker, null, false);
  builder.setView(promptsView);

  DatePicker startDatePicker = (DatePicker)promptsView.findViewById(R.id.startDatePicker);
  DatePicker endDatePicker = (DatePicker)promptsView.findViewById(R.id.endDatePicker);

  final AlertDialog alertDialog = builder.create();
  alertDialog.show();

  Button theButton = alertDialog.getButton(DialogInterface.BUTTON_POSITIVE);
  theButton.setOnClickListener(new CustomListener(alertDialog, startDatePicker, endDatePicker));

警报日志正面按钮的CustomClickLister：

private class CustomListener implements View.OnClickListener {
        private final Dialog dialog;
        private DatePicker mStartDp, mEndDp;
    public CustomListener(Dialog dialog, DatePicker dS, DatePicker dE) {
        this.dialog = dialog;
        mStartDp = dS;
        mEndDp = dE;
    }

    @Override
    public void onClick(View v) {

        int day1  = mStartDp.getDayOfMonth();
        int month1= mStartDp.getMonth();
        int year1 = mStartDp.getYear();
        Calendar cal1 = Calendar.getInstance();
        cal1.set(Calendar.YEAR, year1);
        cal1.set(Calendar.MONTH, month1);
        cal1.set(Calendar.DAY_OF_MONTH, day1);


        int day2  = mEndDp.getDayOfMonth();
        int month2= mEndDp.getMonth();
        int year2 = mEndDp.getYear();
        Calendar cal2 = Calendar.getInstance();
        cal2.set(Calendar.YEAR, year2);
        cal2.set(Calendar.MONTH, month2);
        cal2.set(Calendar.DAY_OF_MONTH, day2);

        if(cal2.getTimeInMillis()>=cal1.getTimeInMillis()){
            dialog.dismiss();
            Log.i("Dialog", "Dismiss");
            // Condition is satisfied so do dialog dismiss
            }else {
            Log.i("Dialog", "Do not Dismiss");
            // Condition is not satisfied so do not dialog dismiss
        }

    }
}

Done

防止对话框在单击时关闭，并且仅在internet可用时关闭

我也在尝试做同样的事情，因为我不希望对话框在互联网连接之前关闭。

这是我的代码：

AlertDialog.Builder builder=new AlertDialog.Builder(MainActivity.this); builder.setTitle("Internet Not Connected");
    if(ifConnected()){

        Toast.makeText(this, "Connected or not", Toast.LENGTH_LONG).show();
    }
    else{
        builder.setPositiveButton("Retry", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
               if(!ifConnected())
               {
                   builder.show();
               }
            }
        }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                finish();
            }
        });
        builder.show();

    }

这是我的连接管理器代码：

 private boolean ifConnected()
{
    ConnectivityManager connectivityManager= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo=connectivityManager.getActiveNetworkInfo();
   return networkInfo!=null && networkInfo.isConnected();
}

科特林

val dialogView = LayoutInflater.from(requireContext()).inflate(R.layout.dialog_userinput, null)
        val dialogBuilder = MaterialAlertDialogBuilder(requireContext(), R.style.AlertDialogTheme)
   
        dialogBuilder.setView(dialogView)
        dialogBuilder.setCancelable(false)
        dialogBuilder.setPositiveButton("send",null)
        dialogBuilder.setNegativeButton("cancel") { dialog,_ ->
        dialog.dismiss()
        }


        val alertDialog = dialogBuilder.create()
        alertDialog.show()

        val positiveButton = alertDialog.getButton(AlertDialog.BUTTON_POSITIVE)
        positiveButton.setOnClickListener {
            val myInputText = dialogView.etxt_userinput.text.toString().trim()
            if(myInputText.isNotEmpty()){
             //Do something
            }else{
                //Prompt error
                dialogView.etxt_userinput.error = "Please fill this"
            }
        }

我们只需使用dialogBuilder创建一个AlertDialog，然后根据需要设置肯定按钮
