上面错误的意思是,在公司自定义的recyclerView这个控件中,在onAttachedToWindow这个方法中,用到了v4包中的ViewComat的getDisplay,而在目前引用的v4包中没有这个方法:

recyclerView中的方法

protected void onAttachedToWindow() {
        super.onAttachedToWindow();
        mLayoutOrScrollCounter = 0;
        mIsAttached = true;
        mFirstLayoutComplete = mFirstLayoutComplete && !isLayoutRequested();
        if (mLayout != null) {
            mLayout.dispatchAttachedToWindow(this);
        }
        mPostedAnimatorRunner = false;

        if (ALLOW_THREAD_GAP_WORK) {
            // Register with gap worker
            mGapWorker = GapWorker.sGapWorker.get();
            if (mGapWorker == null) {
                mGapWorker = new GapWorker();

                // break 60 fps assumption if data from display appears valid
                // NOTE: we only do this query once,statically,because it's very expensive (> 1ms)
                Display display = ViewCompat.getDisplay(this);
                float refreshRate = 60.0f;
                if (!isInEditMode() && display != null) {
                    float displayRefreshRate = display.getRefreshRate();
                    if (displayRefreshRate >= 30.0f) {
                        refreshRate = displayRefreshRate;
                    }
                }
                mGapWorker.mFrameIntervalNs = (long) (1000000000 / refreshRate);
                GapWorker.sGapWorker.set(mGapWorker);
            }
            mGapWorker.add(this);
        }
    }

原因是,在工程的compile中引入recyclerView的时候,去掉了v4包的引用:

compile('com.me.sdk:fme-recyclerview:2.0.+') {
        exclude module: 'support-v4'
        exclude module: 'support-annotations'
        exclude module: 'me-support-v4'
    }

exclude表示,去掉这个module的依赖
所以就找不到v4包里的那个方法了.

于是我把这个注释掉:

compile('com.mei.sdk:fme-recyclerview:2.0.+') {
        /*exclude module: 'support-v4'*/
        exclude module: 'support-annotations'
        exclude module: 'me-support-v4'
    }

这个异常就消失了

另外,附上,gradle依赖的学习资料:

跟我学Gradle-5.3:依赖-管理依赖的版本(传递(transitive)\排除(exclude)\强制(force)\动态版本(+))
