Question

HY！

My Thread.interrupt不起作用。

代码（我们是全球性的）：

//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);
    }

线程中断时需要断开循环：

@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();
        }
    }
}

您期望发生什么？在大量的while循环中你有中断异常:)你需要写中断;在异常部分内部，它退出循环。 if !this.isInterrupted()行仅通过消除内部代码使循环非常紧，但循环仍在外部。

Thread.interrupt（）不起作用
