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。

另一种解决方案

我想从用户体验的角度提出另一个答案。

为什么要在单击按钮时阻止对话框关闭？大概是因为您有一个自定义对话框，用户尚未在其中做出选择或尚未完全填写所有内容。如果他们还没有完成，那么你根本不应该让他们点击肯定按钮。只要禁用它，直到一切就绪。

这里的其他答案提供了许多技巧来覆盖积极的按钮点击。如果这一点很重要的话，安卓系统难道不会提供一个方便的方法吗？他们没有。

相反，Dialogs设计指南显示了这种情况的一个示例。在用户做出选择之前，“确定”按钮将被禁用。根本不需要任何压倒一切的技巧。用户很明显，在继续之前，仍需要做一些事情。

如何禁用正极按钮

有关创建自定义对话框布局的信息，请参阅Android文档。它建议您将AlertDialog放在DialogFragment中。然后，您需要做的就是在布局元素上设置侦听器，以知道何时启用或禁用肯定按钮。

如果自定义对话框具有单选按钮，请使用RadioGroup.OnCheckedChangeListener。如果自定义对话框有复选框，请使用CompoundButton.OnCheckedChangeListener。如果自定义对话框具有EditText，则使用TextWatcher。

正面按钮可以这样禁用：

AlertDialog dialog = (AlertDialog) getDialog();
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);

这是一个完整的正在工作的DialogFragment，带有一个禁用的肯定按钮，如上图所示。

import android.support.v4.app.DialogFragment;
import android.support.v7.app.AlertDialog;

public class MyDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        // inflate the custom dialog layout
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.my_dialog_layout, null);

        // add a listener to the radio buttons
        RadioGroup radioGroup = (RadioGroup) view.findViewById(R.id.radio_group);
        radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup radioGroup, int i) {
                // enable the positive button after a choice has been made
                AlertDialog dialog = (AlertDialog) getDialog();
                dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(true);
            }
        });

        // build the alert dialog
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setView(view)
                .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int id) {
                        // TODO: use an interface to pass the user choice back to the activity
                    }
                })
                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        MyDialogFragment.this.getDialog().cancel();
                    }
                });
        return builder.create();
    }

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

        // disable positive button by default
        AlertDialog dialog = (AlertDialog) getDialog();
        dialog.getButton(AlertDialog.BUTTON_POSITIVE).setEnabled(false);
    }
}

自定义对话框可以从如下活动运行：

MyDialogFragment dialog = new MyDialogFragment();
dialog.show(getFragmentManager(), "MyTag");

笔记

为了简洁起见，我省略了将用户选择信息传递回活动的通信接口。不过，文档显示了如何做到这一点。该按钮在onCreateDialog中仍然为空，因此我在onResume中禁用了它。如果用户切换到另一个应用程序，然后在不关闭对话框的情况下返回，则会再次禁用它。这可以通过取消选择任何用户选项或从onCreateDialog调用Runnable来在下次运行循环中禁用按钮来解决。view.post（newRunnable（）{@覆盖公共空运行（）{AlertDialogdialog=（AlertDialog）getDialog（）；dialog.getButton（AlertDialog.BUTTON.POSITIVE）.setEnabled（false）；}});

带有一个、两个和三个按钮的Android警报对话框如何在Android警报对话框中显示列表视图？

编辑：这只适用于一些评论中提到的API 8+。

这是一个迟到的回答，但您可以在AlertDialog中添加一个onShowListener，然后可以覆盖按钮的onClickListener。

final AlertDialog dialog = new AlertDialog.Builder(context)
        .setView(v)
        .setTitle(R.string.my_title)
        .setPositiveButton(android.R.string.ok, null) //Set to null. We override the onclick
        .setNegativeButton(android.R.string.cancel, null)
        .create();

dialog.setOnShowListener(new DialogInterface.OnShowListener() {

    @Override
    public void onShow(DialogInterface dialogInterface) {

        Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // TODO Do something

                //Dismiss once everything is OK.
                dialog.dismiss();
            }
        });
    }
});
dialog.show();

我找到了另一种方法来实现这一点。。。

步骤1：将对话框打开代码放入方法（或C中的函数）。步骤2：在onClick of yes（您的positiveButton）中，调用此对话框打开如果条件不满足，则递归使用方法（通过使用if…else…）。如下所示：

private void openSave() {
   
    final AlertDialog.Builder builder=new AlertDialog.Builder(Phase2Activity.this);

    builder.setTitle("SAVE")
            .setIcon(R.drawable.ic_save_icon)
            .setPositiveButton("Save", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    
                        if((!editText.getText().toString().isEmpty() && !editText1.getText().toString().isEmpty())){

                                createPdf(fileName,title,file);
                            
                        }else {
                            openSave();
                            Toast.makeText(Phase2Activity.this, "Some fields are empty.", Toast.LENGTH_SHORT).show();
                        }

                    
            })
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
               dialogInterface.dismiss();
            }
        })
            .setCancelable(false)
            .create()
            .show();

}

但这将使对话框消失片刻，并立即再次出现。：）

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

我编写了一个简单的类（AlertDialogBuilder），您可以使用它在按下对话框按钮时禁用自动关闭功能。

它还与Android 1.6兼容，因此它不使用OnShowListener（仅API>=8可用）。

因此，您可以使用此CustomAlertDialogBuilder，而不是使用AlertDialogBuilder。最重要的部分是不应该调用create（），而应该只调用show（）方法。我添加了setCanceledOnTouchOutside（）和setOnDismissListener等方法，这样您仍然可以直接在生成器上设置它们。

我在Android 1.6、2.x、3.x和4.x上测试了它，所以它应该工作得很好。如果你发现一些问题，请在这里评论。

            });
        }

        return alertDialog;
    }   
}

EDIT下面是一个关于如何使用CustomAlertDialogBuilder的小示例：

// Create the CustomAlertDialogBuilder
CustomAlertDialogBuilder dialogBuilder = new CustomAlertDialogBuilder(context);

// Set the usual data, as you would do with AlertDialog.Builder
dialogBuilder.setIcon(R.drawable.icon);
dialogBuilder.setTitle("Dialog title");
dialogBuilder.setMessage("Some text..");

// Set your buttons OnClickListeners
dialogBuilder.setPositiveButton ("Button 1", new DialogInterface.OnClickListener() {
    public void onClick (DialogInterface dialog, int which) {
        // Do something...

        // Dialog will not dismiss when the button is clicked
        // call dialog.dismiss() to actually dismiss it.
    }
});

// By passing null as the OnClickListener the dialog will dismiss when the button is clicked.               
dialogBuilder.setNegativeButton ("Close", null);

// Set the OnDismissListener (if you need it)       
dialogBuilder.setOnDismissListener(new DialogInterface.OnDismissListener() {
    public void onDismiss(DialogInterface dialog) {
        // dialog was just dismissed..
    }
});

// (optional) set whether to dismiss dialog when touching outside
dialogBuilder.setCanceledOnTouchOutside(false);

// Show the dialog
dialogBuilder.show();
