当我们创建一个带EditText 或 AutoCompleteTextView的视图时，在加载视图时总是会把输入的焦点自动移动到第一个输入框。如下图所示：
下面是mail.xml布局文件：
1 . <!--? xml version = " 1.0 " encoding = " utf-8 " ?-->
2 . < linearlayout android:layout_height = " fill_parent " android:layout_width = " fill_parent " android:orientation = " vertical " xmlns:android = " http://schemas.android.com/apk/res/android " >
3 . < button android:id = " @+id/Button01 " android:layout_height = " wrap_content " android:layout_width = " wrap_content " android:text = " @string/button_text " >
4 . < / button>
5 . < edittext android:hint = " @string/hint " android:id = " @+id/EditText01 " android:layout_height = " wrap_content " android:layout_width = " wrap_content " android:text = "" >
6 . < / edittext>
7 . < button android:id = " @+id/Button02 " android:layout_height = " wrap_content " android:layout_width = " wrap_content " android:text = " @string/button_text " >
8 . < / button>
9 . < / linearlayout>
10 .
我们如何才能把焦点从EditText上移除呢？最简单的方法是创建一个不可见的（invisible）LinearLayout，LinearLayout将会把焦点从EditText上移走。
我们修改mail.xml布局文件，在EditText之前增加一个LinearLayout ，如下所示：
1 . <!--? xml version = " 1.0 " encoding = " utf-8 " ?-->
2 . < linearlayout android:layout_height = " fill_parent " android:layout_width = " fill_parent " android:orientation = " vertical " xmlns:android = " http://schemas.android.com/apk/res/android " >
3 . < button android:id = " @+id/Button01 " android:layout_height = " wrap_content " android:layout_width = " wrap_content " android:text = " @string/button_text " >
4 . < / button>
5 . < linearlayout android:focusable = " true " android:focusableintouchmode = " true " android:layout_height = " 0px " android:layout_width = " 0px " >
6 . < edittext android:hint = " @string/hint " android:id = " @+id/EditText01 " android:layout_height = " wrap_content " android:layout_width = " wrap_content " android:text = "" >
7 . < / edittext>
8 . < button android:id = " @+id/Button02 " android:layout_height = " wrap_content " android:layout_width = " wrap_content " android:text = " @string/button_text " >
9 . < / button>
10 . < / linearlayout>
11 . < / linearlayout>
最终效果如下所示：
不需要任何代码就把焦点移除了，是不是最简单的解决方案？
