首先写一个函数来实现弹出框的功能 function myAlert ( text , time ) { if (! document . getElementById ( 'alertBg' )) { let _time = time || 1000 ; let parent = document . createElement ( 'div' ); parent . setAttribute ( 'id' , 'alertBg' ); let child = document . createElement ( 'p' ); child . setAttribute ( 'class' , 'text' ); let _text = document . createTextNode ( text ); child . appendChild ( _text ); parent . appendChild ( child ); document . body . appendChild ( parent ); setTimeout ( function () { document . body . removeChild ( parent ); }, _time ) }; } 然后写css样式 /*弹出提示框*/ #alertBg { position : absolute ;

Toast.LENGTH_SHORT 和 Toast.LENGTH_LONG 两种，前者是2s，后者是显示3.5s。嗯，有些页面的确显示有问题，short太短，long太短，搞得比较尴尬，所以需要分析一下，这Toast到底是怎么运行的，我能不能修改这个时间，让它要多长有多长呢? 我希望你读完这篇文章之后，能了解深层次的Toast运行原理。 Toast .makeText (activity, "hello world" , Toast .LENGTH _SHORT) .show () ; // or Toast .makeText (activity, "hello world" , Toast .LENGTH _LONG) .show () ; 通过源码分析，makeText()方法中，主要是获取LayoutInflater获取一个TextView，这个TextView就是我们的Toast需要显示的View，这个很简单，就不说了，主要来看一下show()方法： /** * 显示特定时长的View */ public void show () { //代码省略 INotificationManager service = getService(); String pkg = mContext.getOpPackageName(); TN tn = mTN; tn.mNextView

Ŀ¼ Ŀ¼ 但是只有广播接收者可以使用java代码的方法来动态注册 。 BroadcastReceiver是用于接收广播的组件用于组件与组件之间进行通信，可以跨应用程序传递. 如操作系统电池电量低会发送一个广播，这样我们的程序里面可以去监听这个广播，可以关 闭程序里面比较耗电的功能,提示用户注意保存进度什么的,还如其它安装新应用等,还有普通应 用程序,例如启动特定线程,文件下载完毕等。 广播的发送的一般应用场合：发送频率低的情况可以使用，数据量小的情况可以使用。 在onReceive方法内，我们可以获取随广播而来的Intent中的数据，这非常重要，就像无线电一样，包含很多有用的信息。 在创建完我们的BroadcastReceiver之后，还不能够使它进入工作状态，我们需要为它注册一个指定的 广播地址 。没有注册广播地址的BroadcastReceiver就像一个缺少选台按钮的收音机，虽然功能俱备，但也无法收到电台的信号。所以创建类后就要对BroadcastReceiver进行注册。 public class MyBroadcastReceiver extends BroadcastReceiver { @Override public void onReceive (Context context, Intent intent) { //对接收到的广播进行处理
