Android笔记之线程使用

1、线程消息处理：

private Handler handler = new Handler(){
        public void handleMessage(Message msg) {

            if (!Thread.currentThread().isInterrupted()) {
                switch (msg.what) {
                case 1:
                   //break;
                case -1:
                    //break;
                }
            }
            super.handleMessage(msg);
        }
    };

创建线程：

download(path,Environment.getExternalStorageDirectory());
.....
private void download(final String path,final File saveDir) {
        new Thread(new Runnable() {
            @Override
            public void run() {
               //
            }
        }).start();
    }
}
