请求焦点不起作用

requestFocus not working(请求焦点不起作用)

问题描述

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="20dp" >

    <AutoCompleteTextView
        android:id="@+id/autocomplete_zone"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:dropDownVerticalOffset="0.2dp"
        android:ems="10"
        android:hint="@string/zone_hint"
        android:inputType="text"
        android:lines="1"
        android:maxLines="1"
        android:popupBackground="#00ffffff"
        android:textColor="#ffffff"
        android:textColorHint="#ffffff" >

        <requestFocus />
    </AutoCompleteTextView>

    <ProgressBar
        android:id="@+id/progressBar1"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignBottom="@id/autocomplete_zone"
        android:layout_alignRight="@id/autocomplete_zone"
        android:layout_alignTop="@id/autocomplete_zone"
        android:paddingBottom="5dp"
        android:visibility="invisible" />
</RelativeLayout>

在上面的标记中

<requestFocus />

不起作用.活动启动时，文本视图未聚焦.这是因为覆盖文本视图的进度条吗?任何想法如何解决这个问题?

does not work. The text view is not focused when the activity is started. Is this because of the progress bar which overlays the text view? Any ideas how to fix this?
