如果你使用的是材料设计，我建议你查看材料对话框。它为我修复了几个与当前打开的Android bug相关的问题（参见78088），但最重要的是，对于这个问题，它有一个autoDismiss标志，可以在使用生成器时设置。

这可能是一个很晚的回复，但使用setCancelable就可以了。

alertDial.setCancelable(false);

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()

对于API 8之前的版本，如果editText的内容不正确，我使用一个布尔标志、一个关闭监听器并再次调用dialog.show来解决这个问题。这样地：

case ADD_CLIENT:
        LayoutInflater factoryClient = LayoutInflater.from(this);
        final View EntryViewClient = factoryClient.inflate(
                R.layout.alert_dialog_add_client, null);

        EditText ClientText = (EditText) EntryViewClient
                .findViewById(R.id.client_edit);

        AlertDialog.Builder builderClient = new AlertDialog.Builder(this);
        builderClient
                .setTitle(R.string.alert_dialog_client)
                .setCancelable(false)
                .setView(EntryViewClient)
                .setPositiveButton("Save",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {
                                EditText newClient = (EditText) EntryViewClient
                                        .findViewById(R.id.client_edit);
                                String newClientString = newClient
                                        .getText().toString();
                                if (checkForEmptyFields(newClientString)) {
                                    //If field is empty show toast and set error flag to true;
                                    Toast.makeText(getApplicationContext(),
                                            "Fields cant be empty",
                                            Toast.LENGTH_SHORT).show();
                                    add_client_error = true;
                                } else {
                                    //Here save the info and set the error flag to false
                                    add_client_error = false;
                                }
                            }
                        })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int id) {
                                add_client_error = false;
                                dialog.cancel();
                            }
                        });
        final AlertDialog alertClient = builderClient.create();
        alertClient.show();

        alertClient
                .setOnDismissListener(new DialogInterface.OnDismissListener() {

                    @Override
                    public void onDismiss(DialogInterface dialog) {
                        //If the error flag was set to true then show the dialog again
                        if (add_client_error == true) {
                            alertClient.show();
                        } else {
                            return;
                        }

                    }
                });
        return true;

这个链接的答案是一个简单的解决方案，它与API 3兼容。它与Tom Bollwitt的解决方案非常相似，但没有使用兼容性较差的OnShowListener。

是的，你可以。您基本上需要：使用DialogBuilder创建对话框show（）对话框在显示的对话框中查找按钮并覆盖其onClickListener

自从我扩展EditTextPreference以来，我对Kamen的代码进行了一些小的修改。

@Override
protected void showDialog(Bundle state) {
  super.showDialog(state);

  class mocl implements OnClickListener{
    private final AlertDialog dialog;
    public mocl(AlertDialog dialog) {
          this.dialog = dialog;
      }
    @Override
    public void onClick(View v) {

        //checks if EditText is empty, and if so tells the user via Toast
        //otherwise it closes dialog and calls the EditTextPreference's onClick
        //method to let it know that the button has been pressed

        if (!IntPreference.this.getEditText().getText().toString().equals("")){
        dialog.dismiss();
        IntPreference.this.onClick(dialog,DialogInterface.BUTTON_POSITIVE);
        }
        else {
            Toast t = Toast.makeText(getContext(), "Enter a number!", Toast.LENGTH_SHORT);
            t.show();
        }

    }
  }

  AlertDialog d = (AlertDialog) getDialog();
  Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
  b.setOnClickListener(new mocl((d)));
}

真有趣！

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
