我希望列表项的背景像进度条一样工作.例如,在tTorrent文件列表中:

现在就是这样做的:我使用了relativelayout和两个线性输出.一个有textview,另一个有两个视图作为进度条.使用视图的权重更改"进度",这是在getView方法中动态设置的.然后将带有textview的linearlayout放在前面.这是代码:

布局:

<LinearLayout
    android:padding="5dp"
    android:id="@+id/catStatsRowLay"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <!-- textviews on the front -->
    ...
</LinearLayout>

<!-- views which work as progress bar -->
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignBottom="@id/catStatsRowLay"
    android:layout_alignLeft="@id/catStatsRowLay"
    android:layout_alignRight="@id/catStatsRowLay"
    android:layout_alignTop="@id/catStatsRowLay"
    android:layout_below="@id/catStatsRowLay"
    android:layoutDirection="rtl"
    android:orientation="horizontal" >

    <View
        android:id="@+id/catStatsRowBar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight=".70"
        android:background="#cc550000" />

    <View
        android:id="@+id/catStatsRowBar2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight=".30"
        android:background="@android:color/transparent" />
</LinearLayout>

</RelativeLayout>

和getView方法:

public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View rowView = inflater.inflate(R.layout.categories_stats_list_row,
                parent, false);

        //filling textviews
        ...

        //getting bars …
