一个Alert弹出框的工具类:AlertUtils

最近在做Android项目的时候总觉得系统提供的Alert弹出框代码过于繁琐, 因此对系统Alert的代码进行了二次封装，这样以后开发的时候再也不用写很多代码了。代码如下:

import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;

/**
 * Alert工具类
 *
 * @author Samoy

 */

public final class AlertUtils {
    private static AlertDialog dialog;
    
    public static void showProgress(Activity activity, String title, String message) {
        if (dialog != null) {
            dismiss();
        }
        dialog = ProgressDialog.show(activity, title, message, false, false);
    }

    public static void dismiss() {
        if (dialog != null) {
            dialog.dismiss();
            dialog = null;
        }
    }

    public static void showAlert(Activity activity, String title, String message) {
        if (dialog != null) {
            dismiss();
        }
        dialog = new AlertDialog.Builder(activity)
                .setTitle(title)
                .setMessage(message)
                .setPositiveButton("确定", null)
                .show();
    }

    public static void showAlert(Activity activity, String title, String message, DialogInterface.OnClickListener onEnsureClick) {
        if (dialog != null) {
            dismiss();
        }
        dialog = new AlertDialog.Builder(activity)
                .setTitle(title)
                .setMessage(message)
                .setPositiveButton("确定", onEnsureClick)
                .show();
    }

    public static void showAlert(Activity activity, String title, String message, DialogInterface.OnClickListener onEnsureClick, DialogInterface.OnClickListener onCancelClick) {
        if (dialog != null) {
            dismiss();
        }
        dialog = new AlertDialog.Builder(activity)
                .setTitle(title)
                .setMessage(message)
                .setPositiveButton("确定", onEnsureClick)
                .setNegativeButton("取消", onCancelClick)
                .show();
    }

    public static void showAlert(Activity activity, String title, String message, DialogInterface.OnClickListener onEnsureClick, DialogInterface.OnClickListener onCancelClick, DialogInterface.OnClickListener onNeutralClick) {
        if (dialog != null) {
            dismiss();
        }
        dialog = new AlertDialog.Builder(activity)
                .setTitle(title)
                .setMessage(message)
                .setPositiveButton("确定", onEnsureClick)
                .setNegativeButton("取消", onCancelClick)
                .setNeutralButton("以后再说", onNeutralClick)
                .show();
    }
}

后记:单项和多项选择以后再实现,这样的需求不是很多。
