在运行时在DialogFragment中设置可见性视图

我试图在运行时更新DialogFragment显示,根据某些条件将视图的可见性设置为可见或消失。

基本上,我在DialogFragment中膨胀布局,在执行一些后台请求时显示进度条,并根据请求的结果更新DialogFragment布局。

有时它可以工作,有时它不会相应地更新我的UI,即使日志显示调用了该方法并且线程是主线程。 知道为什么吗?

在DialogFragment中

@Override
public void showData(List<MyDataViewModel> data) {
    Timber.d("Fragment Show data " + (Looper.myLooper() == Looper.getMainLooper()));
    Timber.d("Fragment Show data " + this);
    Timber.d("Fragment Show data " + data.size());

    if (mConnectedContainer.getVisibility() != View.VISIBLE) {
        mConnectedContainer.setVisibility(View.VISIBLE);
    }
}

活动中

@Override
public void showDialog() {
    // DialogFragment.show() will take care of adding the fragment
    // in a transaction.  We also want to remove any currently showing
    // dialog, so make our own transaction and take care of that here.
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    Fragment prev = getSupportFragmentManager().findFragmentByTag("dialog");
    if (prev != null) {
        ft.remove(prev);
    }
    ft.addToBackStack(null);

    // Create and show the dialog.
    DialogFragment newFragment = MyDialogFragment.newInstance();
    newFragment.show(ft, "dialog");
}

也尝试过这种方式

@Override
public void showDialog() {
    // Create and show the dialog.
    DialogFragment newFragment = MyDialogFragment.newInstance();
    newFragment.show(getSupportFragmentManager(), "dialog");
}
