好的，所以使用textView的技巧不适用于此。所以我知道这必须简单......对吧？因为我可能会帮助我以后添加图片。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/logo"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    >

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textView1"
        android:layout_alignParentBottom="true"
        android:layout_below="@+id/textView1"
        android:paddingLeft="8dp"
        android:paddingRight="8dp" >

    </ListView>

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:text="@string/welcome"
        android:textColor="#b70000"
        android:textSize="16sp" />

</RelativeLayout>

我用它来调用它并添加到java代码中的listview。

您已使用项目布局android.R.layout.simple_list_item_1指定了内置适配器（ArrayAdapter）。

如果您想要自定义布局，可以将Android SDK中的simple_list_item_1.xml布局（在platforms / android-18 / data / res / layout文件夹中查找）复制到项目中并进行修改。例如，您将其命名为my_simple_list_item_1.xml。

然后修改你的代码以使用你的布局，而不是android.R.layout.simple_list_item_1：

setListAdapter(new ArrayAdapter<String>(this, R.layout.my_simple_list_item_1, CHOICES));

您会看到Androids simple_list_item_1布局只是一个 TextView ，您可以将textColor属性添加到它并根据自己的喜好进行修改。
