在AlertDialog上使用DialogFragment:

Since the introduction of API level 13: the showDialog method from Activity is deprecated. Invoking a dialog elsewhere in code is not advisable since you will have to manage the the dialog yourself (e.g. orientation change). Difference DialogFragment - AlertDialog Are they so much different? From Android reference regarding DialogFragment: A DialogFragment is a fragment that displays a dialog window, floating on top of its activity's window. This fragment contains a Dialog object, which it displays as appropriate based on the fragment's state. Control of the dialog (deciding when to show, hide, dismiss it) should be done through the API here, not with direct calls on the dialog. Other notes Fragments are a natural evolution in the Android framework due to the diversity of devices with different screen sizes. DialogFragments and Fragments are made available in the support library which makes the class usable in all current used versions of Android.

你可以创建一般的DialogFragment子类，如YesNoDialog和OkDialog，并传入标题和消息，如果你在应用程序中使用对话框很多。

public class YesNoDialog extends DialogFragment
{
    public static final String ARG_TITLE = "YesNoDialog.Title";
    public static final String ARG_MESSAGE = "YesNoDialog.Message";

    public YesNoDialog()
    {

    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        Bundle args = getArguments();
        String title = args.getString(ARG_TITLE);
        String message = args.getString(ARG_MESSAGE);

        return new AlertDialog.Builder(getActivity())
            .setTitle(title)
            .setMessage(message)
            .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int which)
                {
                    getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_OK, null);
                }
            })
            .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int which)
                {
                    getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_CANCELED, null);
                }
            })
            .create();
    }
}

然后使用以下命令调用它:

    DialogFragment dialog = new YesNoDialog();
    Bundle args = new Bundle();
    args.putString(YesNoDialog.ARG_TITLE, title);
    args.putString(YesNoDialog.ARG_MESSAGE, message);
    dialog.setArguments(args);
    dialog.setTargetFragment(this, YES_NO_CALL);
    dialog.show(getFragmentManager(), "tag");

并在onActivityResult中处理结果。

使用Dialog进行简单的是或否对话框。

当你需要更复杂的视图，其中你需要获得生命周期，如oncreate，请求权限，任何生命周期覆盖我将使用一个对话框片段。因此，您可以分离权限和对话框需要操作的任何其他代码，而不必与调用活动通信。

DialogFragment基本上是一个可以用作对话框的片段。

使用DialogFragment而不是Dialog的原因如下: 在配置更改和保存&恢复流程后，自动重新创建DialogFragment DialogFragment继承了完整的Fragment生命周期 不再有illegalstateexception和泄漏的窗口崩溃。当活动被警报对话框破坏时，这是非常常见的 还在那里。

更详细地

我建议使用DialogFragment。

当然，用它创建一个“Yes/No”对话框是相当复杂的，因为它应该是相当简单的任务，但用dialog创建一个类似的对话框也是令人惊讶地复杂。

(活动的生命周期使它变得复杂-你必须让Activity管理对话框的生命周期-没有办法传递自定义参数，例如自定义消息给Activity。如果使用API级别低于8)

这样做的好处是，你通常可以很容易地在DialogFragment之上构建自己的抽象。

我可以建议简化一下@ashishduh的回答吗:

public class AlertDialogFragment extends DialogFragment {
public static final String ARG_TITLE = "AlertDialog.Title";
public static final String ARG_MESSAGE = "AlertDialog.Message";

public static void showAlert(String title, String message, Fragment targetFragment) {
    DialogFragment dialog = new AlertDialogFragment();
    Bundle args = new Bundle();
    args.putString(ARG_TITLE, title);
    args.putString(ARG_MESSAGE, message);
    dialog.setArguments(args);
    dialog.setTargetFragment(targetFragment, 0);
    dialog.show(targetFragment.getFragmentManager(), "tag");
}

public AlertDialogFragment() {}

@NonNull
@Override
public AlertDialog onCreateDialog(Bundle savedInstanceState)
{
    Bundle args = getArguments();
    String title = args.getString(ARG_TITLE, "");
    String message = args.getString(ARG_MESSAGE, "");

    return new AlertDialog.Builder(getActivity())
            .setTitle(title)
            .setMessage(message)
            .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int which)
                {
                    getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_OK, null);
                }
            })
            .create();
}

它消除了(类的)用户熟悉组件内部结构的需要，并使使用变得非常简单:

AlertDialogFragment.showAlert(title, message, this);

附注:在我的情况下，我需要一个简单的警告对话框，所以这就是我所创建的。您可以将该方法应用于Yes/No或您需要的任何其他类型。
