android已经将UI操作放入主线程，仍然报错

Question

在activity里就没问题，到了自定义class里就不行了 ，弹框之后，点 取消按钮 就报错：Only the original thread that created a view hierarchy can touch its views.

创建与引用时必须在同一线程，这个地方可能要调整

public BluetoothListDialog(Activity activity, BLEClickListener listener1) {
  ...
  dialog = new Dialog(activity);
