本文详细介绍了如何避免在Activity的onRestoreInstanceState方法中出现闪退错误，特别是在自定义View时。通过重写onSaveInstanceState和onRestoreInstanceState方法，正确保存和恢复状态，避免不同类型的View具有相同ID的问题。

activity的onRestoreInstanceState 方法抛出This usually happens when two views of different type have the same id in the same hierarchy
protected void onRestoreInstanceState(Bundle savedInstanceState)

注意检查当前界面自定义view

onSaveInstanceState() 以及onRestoreInstanceState(Parcelable state)方法

参考如下（不要使用网上说的可以用bundle的方式，那样照样闪退）

 @Override
    protected Parcelable onSaveInstanceState() {
        Parcelable superState = super.onSaveInstanceState();
        SavedState savedState = new SavedState(superState);
        savedState.textColor = getTextColor();
        savedState.progressSize = getProgressTextSize();
        savedState.reachedBarHeight = getReachedBarHeight();
        savedState.unReachedBarHeight = getUnreachedBarHeight();
        savedState.reachedBarColor = getReachedBarColor();
        savedState.unReachedBarColor = getUnreachedBarColor();
        savedState.max = getMax();
        savedState.progress = getProgress();
        savedState.suffix = getSuffix();
        savedState.prefix = getPrefix();
        savedState.progressTextVisibile = getProgressTextVisibility() == true ? 1 : 0;
        return savedState;
    }

    @Override
    protected void onRestoreInstanceState(Parcelable state) {
        SavedState savedState = (SavedState) state;
        super.onRestoreInstanceState(savedState.getSuperState());
        mTextColor = savedState.textColor;
        mTextSize = savedState.progressSize;
        mReachedBarHeight = savedState.reachedBarHeight;
        mUnreachedBarHeight = savedState.unReachedBarHeight;
        mReachedBarColor = savedState.reachedBarColor;
        mUnreachedBarColor = savedState.unReachedBarColor;
        initializePainters();
        setMax(savedState.max);
        setProgress(savedState.progress);
        setPrefix(savedState.prefix);
        setSuffix(savedState.suffix);
        setProgressTextVisibility(savedState.progressTextVisibile == 1 ? ProgressTextVisibility.Visible : ProgressTextVisibility.Invisible);
    }
