private void loadStatesView(LayoutInflater inflater, ViewGroup container) {
    mSuccessView = loadSuccessView(inflater, container);
    mBaseContainer.addView(mSuccessView);
    mLoadingView = loadLoadingView(inflater, container);
    mBaseContainer.addView(mLoadingView);
    mErrorView = loadErrorView(inflater, container);
    mBaseContainer.addView(mErrorView);

    setUpState(State.EMPTY);
}

debug之后，发现createView会重复调用，loadData也就重复调用，导致之前SUCCESS值被冲掉，会在覆盖一层EMPTY的界面。也就看到了这些表象。希望高人指点！
