Answer 1

原来是因为自定义的textView导致崩溃。

我删除了它并用普通（android SDK）textView 替换了它，现在它工作正常:)

我删除的代码如下：

class MyCustomizedTextView : AppCompatTextView {
    constructor(context: Context) : super(context)

    constructor(context: Context, attrs: AttributeSet) : super(context, attrs) {
        init(context, attrs)
    }

    constructor(context: Context, attrs: AttributeSet, defStyleAttr: Int) : super(context, attrs, defStyleAttr) {
        init(context, attrs)
    }

    private lateinit var iconTypefaceSpan: CalligraphyTypefaceSpan

    private fun init(context: Context, attrs: AttributeSet) {
        if(!isInEditMode) {
            iconTypefaceSpan = CalligraphyTypefaceSpan(
                TypefaceUtils.load(context.assets,
                               context.getString(R.string.font)
            )
        )
    }
  }
}
