出现此问题是由于dialog.show()之前调用了dialog.setContentView()或者dialog.getwindow()等，正确的应该是dialog.show()之后调用dialog.setContentView()

Caused by: Android.util.AndroidRuntimeException: requestFeature() must be called before adding content

[html]view plain copy
setContentView(R.layout.main);  
requestWindowFeature(Window.FEATURE_NO_TITLE);   

解决方法如下：顺序换一下

[html]view plain copy
requestWindowFeature(Window.FEATURE_NO_TITLE);   
  
setContentView(R.layout.main);
