问题描述
海兰!
我的了Thread.interrupt不起作用。
code(我们是全球性的):
//调用我们=新UpdateState(参数,可以HUP);
us.start();// Interupt
@覆盖
公共布尔onOptionsItemSelected(菜单项项){ 如果(item.getItemId()== R.id.stopthread)
{
Log.e(杀,杀);
us.interrupt();
}
返回super.onOptionsItemSelected(项目);
}

公开处理程序处理程序;
公开处理程序插件; 公共UpdateState(列表<&的NameValuePair GT;参数,可以最终处理程序处理){
this.handler =处理程序;
this.params =参数;
this.ins =新的处理程序(){
@覆盖
公共无效的handleMessage(消息MSG){ 如果(msg.obj.toString()!= NULL)
{
JSONParse JSON = NULL;
尝试
{
消息MSG 2 =新的Message();
Log.e(Channel_State_Update,msg.obj.toString());
JSON =新JSONParse(msg.obj.toString());
字符串状态= json.getChannelState();
Log.e(Channel_State_Send状态);
msg2.obj =状态;
handler.sendMessage(MSG 2); }
赶上(最终例外五)
{
e.printStackTrace();
}
}
}
};
} @覆盖
公共无效的run(){ 而(真)
{
如果(!this.isInterrupted())
{
的HttpConnection CON =新的HttpConnection(参数,可以http://surfkid.redio.de/getChannelState,this.ins);
con.start();
尝试{
Log.e(睡眠,开始);
UpdateState.this.sleep(5000);
Log.e(睡眠,结束);
}赶上(InterruptedException的E){
// TODO自动生成catch块
Log.e(睡眠,错误);
e.printStackTrace();
}
}
//super.run();
}
}
}
请帮忙

解决方案
您需要打破一个循环时,线程被中断:
@覆盖
公共无效的run(){
而(!this.isInterrupted()){//当线程的中断标志设置退出
的HttpConnection CON =新的HttpConnection(参数,可以http://surfkid.redio.de/getChannelState,this.ins);
con.start();
尝试{
Log.e(睡眠,开始);
UpdateState.this.sleep(5000);
Log.e(睡眠,结束);
}赶上(InterruptedException的E){
Log.e(睡眠,错误);
e.printStackTrace(); //捕获InterruptedException的后恢复中断标志
//使循环条件为假
Thread.currentThread()中断()。
}
}
}
Hy!
My Thread.interrupt doesn't work.
Code (us is global):
//Call
us = new UpdateState(params, hup);
us.start();
//Interupt
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId()== R.id.stopthread)
{
Log.e("Kill", "Kill");
us.interrupt();
}
return super.onOptionsItemSelected(item);
}

Log.e("Channel_State_Update",msg.obj.toString());
json = new JSONParse(msg.obj.toString());
String state = json.getChannelState();
Log.e("Channel_State_Send",state);
msg2.obj = state;
handler.sendMessage(msg2);
}
catch (final Exception e)
{
e.printStackTrace();
}
}
}
};
}
@Override
public void run() {
while (true)
{
if (!this.isInterrupted())
{
HttpConnection con = new HttpConnection(params, "http://surfkid.redio.de/getChannelState", this.ins);

解决方案
You need to break a loop when thread is interrupted:
@Override
public void run() {
while (!this.isInterrupted()) { // Exit when thread's interrupt flag is set
HttpConnection con = new HttpConnection(params, "http://surfkid.redio.de/getChannelState", this.ins);
con.start();
try {
Log.e("Sleep", "Begin");
UpdateState.this.sleep(5000);
Log.e("Sleep", "End");
} catch (InterruptedException e) {
Log.e("Sleep", "Error");
e.printStackTrace();
// Restore interrupt flag after catching InterruptedException
// to make loop condition false
Thread.currentThread().interrupt();
}
}
}
