我的代码是这么写的：
<span style="font-size:14px;">View view = View.inflate(this, R.layout.layout_alert_dialog, null); AlertDialog alertDialog = new AlertDialog.Builder(this).create(); alertDialog.setContentView(view); alertDialog.show();</span>
很简单的一个添加，把AlertDialog换成Dialog就没有问题，但是还是想用AlertDialog，试了很多方式，还是报这个错误，后来解决了，由于alertDialog.show()之前调用了alertDialog.setContentView()了，正确的应该是alertDialog.show()之后调用alertDialog.setContentView(),两句换一下位置即可，迷茫了几个小时，原来这么解决！真让人蛋疼
