安卓获取线程id

错误的做法：

    @Override
    public void onCreate() {
        mContext = getApplicationContext();
        mHandler = new Handler();
        mMainThreadid = android.os.Process.myPid(); 6         super.onCreate();
    }

正确的做法：

    @Override
    public void onCreate() {
        mContext = getApplicationContext();
        mHandler = new Handler();
        mMainThreadid = android.os.Process.myTid(); 6         super.onCreate();
    }
