解决之道：在EditText的父级控件中找一个，设置成
android:focusable="true"
android:focusableInTouchMode="true"
这样，就把EditText默认的行为截断了！
<LinearLayout style="@style/FillWrapWidgetStyle" android:orientation="vertical" android:background="@color/black" android:gravity="center_horizontal" android:focusable="true" android:focusableInTouchMode="true" <ImageView android:id="@+id/logo" style="@style/WrapContentWidgetStyle" android:background="@drawable/dream_dictionary_logo" /> <RelativeLayout style="@style/FillWrapWidgetStyle" android:background="@drawable/searchbar_bg" android:gravity="center_vertical" > <EditText android:id="@+id/searchEditText" style="@style/WrapContentWidgetStyle" android:background="@null" android:hint="Search" android:layout_marginLeft="40dp" android:singleLine="true" /> </RelativeLayout> </LinearLayout>
