莫名其妙的报错

错误原因是不在主线程调用了弹窗方法

解决方法很简单

创建Handler

static final int REFRESH_COMPLETE = 0X1112;

    private Handler mHandler = new Handler() {public void handleMessage(android.os.Message msg) {switch (msg.what) {case REFRESH_COMPLETE:ObServernotice.getInstance().notifyObserver(211,1,"",null);
//todo...在这里调用弹窗break;}}};

子线程调用mHandler

if (MainActivity.this instanceof Activity) {if ( (MainActivity.this).isFinishing()) {return ;}
}

mHandler.sendEmptyMessageDelayed(REFRESH_COMPLETE, 1000);
