本文介绍了解决Android中AutoCompleteTextView下拉菜单显示不正确的问题，特别是在320*240分辨率设备上的异常表现。通过调整布局属性，确保了下拉列表能够正确显示。

android widgets:

1: AutoCompleteTextView

1.1 AutoCompleteTextView dropdown item can not be shown correctly .

in 320*240 phonens it may show above AutoCompleteTextView not bellow.

this problem is caused by an attibute: android:layout_margin

this code will cause err showing as upper:

	<AutoCompleteTextView android:id="@+id/wf_input_edit"
				android:layout_width="180dip" 
				android:layout_height="wrap_content"
				android:textSize="14dip" 
				android:layout_margin="20dip"
				android:layout_gravity="center"
				android:singleLine="true"
				android:completionThreshold="1"
				android:hint="@string/citysearch_hint2"  />

after change it to follws every thing seems to be fine (on 320*240 & 800*480 ) the only thing i changed is the "layout_margin"

<AutoCompleteTextView android:id="@+id/wf_input_edit"
				android:layout_width="180dip" 
				android:layout_height="wrap_content"
				android:textSize="14dip" 
				android:layout_marginLeft="20dip"
				android:layout_marginRight="20dip"
				android:layout_gravity="center"
				android:singleLine="true"
				android:completionThreshold="1"
				android:hint="@string/citysearch_hint2"  />
