android 延时执行的几种方式

1. new<wbr>Thread(</wbr>new<wbr>Runnable(){<wbr><wbr></wbr></wbr></wbr>
2. <wbr><wbr><wbr><wbr><span style="word-wrap:normal; word-break:normal; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; border-top-style:none; border-right-style:none; border-bottom-style:none; border-left-style:none; border-width:initial; border-color:initial; color:rgb(0,102,153); background-color:inherit"><strong>public</strong></span><span style="word-wrap:normal; word-break:normal; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; border-top-style:none; border-right-style:none; border-bottom-style:none; border-left-style:none; border-width:initial; border-color:initial; background-color:inherit"><wbr></wbr></span><span style="word-wrap:normal; word-break:normal; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; border-top-style:none; border-right-style:none; border-bottom-style:none; border-left-style:none; border-width:initial; border-color:initial; color:rgb(0,102,153); background-color:inherit"><strong>void</strong></span><span style="word-wrap:normal; word-break:normal; padding-top:0px; padding-right:0px; padding-bottom:0px; padding-left:0px; margin-top:0px; margin-right:0px; margin-bottom:0px; margin-left:0px; border-top-style:none; border-right-style:none; border-bottom-style:none; border-left-style:none; border-width:initial; border-color:initial; background-color:inherit"><wbr>run(){<wbr><wbr></wbr></wbr></wbr></span></wbr></wbr></wbr></wbr>
3. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>Thread.sleep(XXXX);<wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
4. <wbr><wbr><wbr><wbr><wbr><wbr><wbr><wbr>handler.sendMessage();----告诉主线程执行任务<wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr></wbr>
5. <wbr><wbr><wbr><wbr>}<wbr><wbr></wbr></wbr></wbr></wbr></wbr></wbr>
6. }).start<wbr><wbr></wbr></wbr>

② 利用定时器

5. };<wbr><wbr></wbr></wbr>
6. Timer timer = new Timer();
   timer.schedule(task, delay);
