让手机振动时，屏幕关闭

本文介绍了让手机振动时，屏幕关闭的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我要寻找一种方式，让我的程序，使手机震动后屏幕已经超时关闭。我已经做了很多的研究，并没有发现一些作品。我已经看过了电源管理器类，更具体的WakeLock机制。从很多帖子的声音，我需要使用WakeLock类的PARTIAL_WAKE_LOCK变量。

  

PARTIAL_WAKE_LOCK - 唤醒锁，保证了CPU运行

。

不过，我不能把它当屏幕关闭振动手机。我知道我使用正确WakeLock，因为我可以得到SCREEN_DIM_WAKE_LOCK工作。是PARTIAL_WAKE_LOCK什么，我找？

解决方案

@覆盖     公共无效的onCreate（）{         super.onCreate（）;         //注册接收器，手柄屏幕上，屏幕关闭逻辑         IntentFilter的过滤器=新的IntentFilter（Intent.ACTION_SCREEN_ON）;         filter.addAction（Intent.ACTION_SCREEN_OFF）;         BroadcastReceiver的mReceiver =新ScreenReceiver（）;         registerReceiver（mReceiver，过滤器）;     }     @覆盖     公共无效ONSTART（意向意图，诠释startId）{         布尔screenOn = intent.getBooleanExtra（screen_state，假）;         如果（！screenOn）{             //获取振动器的情况下，从当前上下文             振动器V =（震动）getSystemService（Context.VIBRATOR_SERVICE）;            //这个例子将导致手机震动SOS的莫尔斯code            //在莫尔斯code，S=点 - 点 - 点，O=破折号，破折号，破折号            //有停顿，以独立的点/破折号，字母和单词            //下面的数字重新present毫秒长度             INT点= 200; //的莫尔斯code以毫秒为单位点长度            INT破折号= 500; //在毫秒莫尔斯code冲刺长             INT short_gap = 200; //峡长点/破折号之间            INT medium_gap = 500; //间隙长度字母之间            INT long_gap = 1000; //间隙长度词的             长[]模式= {              0，//立即开始              点，short_gap，圆点，short_gap，圆点，//小号              medium_gap，              破折号，short_gap，破折号，short_gap，破折号，//Ø             medium_gap，             点，short_gap，圆点，short_gap，圆点，//小号            long_gap            };            //只有执行该模式的一个时间（-1表示不重复）           v.vibrate（图案，-1）;         } 其他 {             //你的code         }     }

请注意û必须添加使用，允许行到你的Manifest.xml文件，块之外。

＆LT;舱单的xmlns：机器人=htt​​p://schemas.android/apk/res/android包=...＆GT; ＆LT;使用-权限的Andr​​oid：名称=android.permission.VIBRATE/＆GT;

请注意：您还必须在真正的手机测试这个code，仿真器将无法viberate

I am looking for a way to allow my program to make the phone vibrate after the screen has turned off from timing out. I have done lots of research, and have not found something that works. I have looked at the PowerManager class and more specifically the WakeLock mechanism. From the sound of many posts, I would need to use the PARTIAL_WAKE_LOCK variable of the WakeLock class.

PARTIAL_WAKE_LOCK - Wake lock that ensures that the CPU is running.

However, I cannot get it to vibrate the phone when the screen turns off. I know I am using the WakeLock correctly because I can get SCREEN_DIM_WAKE_LOCK to work. Is PARTIAL_WAKE_LOCK what I am looking for?

解决方案

@Override public void onCreate() { super.onCreate(); // REGISTER RECEIVER THAT HANDLES SCREEN ON AND SCREEN OFF LOGIC IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON); filter.addAction(Intent.ACTION_SCREEN_OFF); BroadcastReceiver mReceiver = new ScreenReceiver(); registerReceiver(mReceiver, filter); } @Override public void onStart(Intent intent, int startId) { boolean screenOn = intent.getBooleanExtra("screen_state", false); if (!screenOn) { // Get instance of Vibrator from current Context Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); // This example will cause the phone to vibrate "SOS" in Morse Code // In Morse Code, "s" = "dot-dot-dot", "o" = "dash-dash-dash" // There are pauses to separate dots/dashes, letters, and words // The following numbers represent millisecond lengths int dot = 200; // Length of a Morse Code "dot" in milliseconds int dash = 500; // Length of a Morse Code "dash" in milliseconds int short_gap = 200; // Length of Gap Between dots/dashes int medium_gap = 500; // Length of Gap Between Letters int long_gap = 1000; // Length of Gap Between Words long[] pattern = { 0, // Start immediately dot, short_gap, dot, short_gap, dot, // s medium_gap, dash, short_gap, dash, short_gap, dash, // o medium_gap, dot, short_gap, dot, short_gap, dot, // s long_gap }; // Only perform this pattern one time (-1 means "do not repeat") v.vibrate(pattern, -1); } else { // YOUR CODE } }

note u must Add the uses-permission line to your Manifest.xml file, outside of the block.

<manifest xmlns:android="schemas.android/apk/res/android" package="..."> <uses-permission android:name="android.permission.VIBRATE"/>

note : you must also test this code on a real phone , emulator can't viberate
