AndroidStudio_android通过自定义来实现倒计时的AlertDialog

截图,还是蛮漂亮的,当然大家可以按照自己的需求,去自己定义效果.

1.首先看一下:PromptDialog类,这个类中有些修改的地方,可以复制直接使用 ,当然也可以根据需要,去掉,倒计时的功能.

public class PromptDialog {

    public  void showConfirm(Activity content, String title, final AlertDialogBtnClickListener confirm) {
        //1.首先销毁上次的对话框
        if(dialog!=null){
            dialog.dismiss();
        }

        builder.setCancelable(true);   //返回键dismiss

        //创建对话框
        //final AlertDialog dialog = builder.create();

        dialog.setCancelable(false);

        dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
            @Override
            public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
                if (keyCode == KeyEvent.KEYCODE_SEARCH) {
                    return true;

        try{
            dialog.show();
        }catch (Exception e){

        }

    }

    public static void showNext(Activity content, String title, final AlertDialogBtnClickListener next1Listener) {
        View view = LayoutInflater.from(content).inflate(R.layout.dialog_next, null);
        TextView mTitle = view.findViewById(R.id.dialog_title);
        TextView dialog_next1_bt = view.findViewById(R.id.dialog_next1_bt);

        ImageView dialog_close = view.findViewById(R.id.dialog_close);
        mTitle.setText(title);

        AlertDialog.Builder builder = new AlertDialog.Builder(content);
        builder.setView(view);
        builder.setCancelable(true);   //返回键dismiss
        //创建对话框
        final AlertDialog dialog = builder.create();
        dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);//去掉圆角背景背后的棱角
        dialog.setCancelable(false);
        dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
            @Override
            public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
                if (keyCode == KeyEvent.KEYCODE_SEARCH) {
                    return true;
                } else {
                    return false; //默认返回 false
                }
            }
        });
//        dialog.setCanceledOnTouchOutside(cancelableTouchOut);   //失去焦点dismiss
        dialog_next1_bt.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.dismiss();
                next1Listener.clickNext1();
            }

                    return false; //默认返回 false
                }
            }
        });

        dialog.show();
    }
}

2.然后我们去看看这里面使用到的一些配置文件和图片等资源

用到的xml界面文件是这个:

D:\YdFaceApp\gatelibrary\src\main\res\layout\dialog_confrim.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/dialog_loading_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/x30"
        android:background="@drawable/bg_bai_r4"
        android:orientation="vertical">

        <TextView
            android:id="@+id/dialog_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:paddingTop="@dimen/x40"
            android:paddingBottom="@dimen/x40"
            android:text="确定退出测量？"
            android:textColor="@color/hei"
            android:textSize="@dimen/x16">

        </TextView>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="0.5dp"
            android:background="@color/hui">

        </TextView>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <TextView
                android:id="@+id/dialog_confirm_bt"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center"
                android:padding="@dimen/x20"
                android:text="确定"
                android:textColor="@color/main_select"
                android:textSize="@dimen/x16">

            </TextView>

            <TextView
                android:layout_width="0.5dp"
                android:layout_height="match_parent"
                android:layout_marginTop="5dp"
                android:layout_marginBottom="5dp"
                android:background="@color/hui"
                tools:ignore="Suspicious0dp"></TextView>

            <TextView
                android:id="@+id/dialog_cancel_bt"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:gravity="center"
                android:padding="@dimen/x20"
                android:text="取消"
                android:textSize="@dimen/x16">

            </TextView>
        </LinearLayout>
    </LinearLayout>


</LinearLayout>

3.然后里面使用到的一些dimen

D:\YdFaceApp\gatelibrary\src\main\res\values\lay_x.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <dimen name="x10">10dp</dimen>
    <dimen name="x12">12dp</dimen>
    <dimen name="x14">14dp</dimen>
    <dimen name="x16">16dp</dimen>
    <dimen name="x18">18dp</dimen>
    <dimen name="x20">20dp</dimen>
    <dimen name="x22">22dp</dimen>
    <dimen name="x24">24dp</dimen>
    <dimen name="x26">26dp</dimen>
    <dimen name="x28">28dp</dimen>
    <dimen name="x30">30dp</dimen>
    <dimen name="x40">40dp</dimen>
    <dimen name="x50">50dp</dimen>
    <dimen name="x60">60dp</dimen>
    <dimen name="x70">70dp</dimen>
    <dimen name="x80">80dp</dimen>
</resources>

4.然后使用到的颜色文件

D:\YdFaceApp\gatelibrary\src\main\res\values\colors.xml 可能有些用不到的,到时候复制过去,删除就可以了.

<?xml version="1.0" encoding="utf-8"?>
<!--
  ~ Copyright (C) 2018 Baidu, Inc. All Rights Reserved.
  -->
<resources>
    <color name="pay_bg">#f2f2f2</color>
    <color name="login_bg">#f4f7fa</color>
    <color name="login_edit_bg">#eeeeee</color>
    <color name="login_submit">#19aa8d</color>
    <color name="hei6">#666666</color>
    <color name="hui">#eeeeee</color>
    <color name="hui_48">#484848</color>
    <color name="white_blue">#b8f7e0</color>
</resources>

5.然后使用到的

@drawable/bg_bai_r4 这个自定义的图形

D:\YdFaceApp\gatelibrary\src\main\res\drawable\bg_bai_r4.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/white" />
            <!-- 圆角的半径 -->
            <corners android:radius="15dp" />
        </shape>
    </item>
</layer-list>

6.然后需要的

R.id.dialog_confirm_bt

R.id.dialog_cancel_bt

在 D:\YdFaceApp\gatelibrary\src\main\res\layout\dialog_confrim.xml 文件中已经有了,然后我们去看,如何使用这个alertDialog去.

7.可以看到下面就是使用的过程了

 //1.这里是采用自己设计的dialog画面来进行
                final boolean[] isNeedExit = {true};
                final Integer[] countTime = {32};
                final boolean isBooleanExit = false;
                final Timer timer = new Timer();
                final PromptDialog promptDialog =new PromptDialog();

                final TimerTask task = new TimerTask() {
                    @Override
                    public void run() {
                        /**
                         *要执行的操作
                         */
                        countTime[0] = countTime[0] - 1;
                        if(countTime[0]<=0){
                            if(promptDialog.timerExited){ // 通过这个promptDialog.timerExited可以判断,promptDialog内部的倒计时timer是否已经倒计时结束
                                // 实现页面跳转
                                .....要执行的业务逻辑
                                timer.cancel();
                                finish();
                            }
                        }
                    }
                };

                new Handler(new Handler.Callback() {
                    @Override
                    public boolean handleMessage(Message msg) {
                        try{
                            //实现页面跳转
                            promptDialog.showConfirm(FaceBodyCheckActivity.this, "确定退出测量？", new PromptDialog.AlertDialogBtnClickListener() {
                                @Override
                                public void clickNext1() {
                                    //确定按钮
                                    new Handler(new Handler.Callback() {
                                        @Override
                                        public boolean handleMessage(Message msg) {
                                            Toast.makeText(FaceBodyCheckActivity.this,"3秒后退出测量",Toast.LENGTH_LONG).show();
                                            //3.3秒以后调用退出接口
                                            isNeedExit[0] =false;

                                            new Handler(new Handler.Callback() {
                                                @Override
                                                public boolean handleMessage(Message msg) {
                                                    // 实现页面跳转
                                                    //下面是要实现的业务逻辑
                                                    commLock.lock();
                                                    logOutFrame();
                                                    commLock.unlock();
                                                    timer.cancel();
                                                    finish();
                                                    return  true;
                                                }
                                            }).sendEmptyMessageDelayed(0, 4000); //3秒以后,发送空消息

                                            return  true;
                                        }
                                    }).sendEmptyMessageDelayed(0, 600); //3秒以后,发送空消息
                                }

                                @Override
                                public void clickNext2() {
                                    //取消按钮
                                    isNeedExit[0] =false;
                                    timer.cancel();
                                }

                                @Override
                                public void closeListener() {
                                    //关闭按钮

                                }
                            });

                            //这里就是判断,当第一次进来的时候,先去开启timer,进行倒计时
                            //开启timer,注意在PromptDialog中也有一个timer,那个timer
                            //是用来显示倒计时用的.

                            if(isNeedExit[0]){
                                timer.schedule(task, 1000,1000);
                            }

                        }catch (Exception e){
                            e.printStackTrace();
                        }

                        return  true;
                    }
                }).sendEmptyMessageDelayed(0, 4000); //3秒以后,发送空消息

去看看代码,应该就能明白了,不过我还是要解释一下:

在PromptDialog中有个timer,我们可以在里面写上,需要显示倒计时多长时间,他就会自动倒计时了,然后

在PromptDialog中还有一个变量timerExited,如果PromptDialog中的那个timer倒计时完了,到0了,那么

它里面的这个PromptDialog,就把timerExited设置为true,表示已经倒计时结束.

然后可以看到使用这个PromptDialog的时候,同样我也用了一个timer倒计时,等这个倒计时完了以后,

我会去判断PromptDialog中的那个timerExited是不是true了,如果是true,表示promptDialog的timer也倒计时完了

这个时候,我就可以做业务处理, 比如倒计时结束后是自动退出界面啊...还是怎么样,上面是自动退出界面.
