--------------------

**解决方案**  
`直接上最简单的方法`

*  在布局中引入id  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MjQ3MzIyOA_size_16_color_FFFFFF_t_70 1]
 *  删除冗余代码  
    ![在这里插入图片描述][20210319161818207.png]
 *  然后如是用

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
    	...
        weatherBinding= ActivityWeatherBinding.inflate(layoutInflater)
        setContentView(weatherBinding.root)
        ...
    }
    
    //用法
    weatherBinding.includeNow.placeName.text=viewModel.placeName
