Question

我的应用程序中有一个对话框。当我点击忘记密码textview时，对话框打开。但布局顶部有一条水平线，同时给布局充气。我想删除那条水平线。下面是对话框的xml代码。

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

您可以在setContentView（）之前使用它删除水平线：

requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.your_dialog);

Answer 2

Dialog dialog = new Dialog(Main_Activity.this);    
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.your_dialog);

Android对话框，删除水平线
