android中的dialog 中也就是说child已经有一个parent,必须进行removeView(),出错的具体原因我也不是特别的清楚不过下面是我解决的方法,可以从window窗口中直接继承过来!

public void afterContextInput() {AlertDialog builder = new AlertDialog.Builder(mActivity).create(); builder.show();builder.getWindow().setContentView(R.layout.edittext_input);builder.setCancelable(false);}

这样的话可以从window中直接继承就不用在从你的类中继承了!

讲的不是清晰,知道怎么解决就好,如果不明白可以留言!
