Question

我在下面发布我的代码，在下面的布局中，布局中显示的顶部有一个空格。我只想删除顶部空间并尝试在顶部显示标题。但我很困惑如何设置它。请建议我解决。谢谢。

如果您只是询问顶部没有空格的两个文本对齐方式，那么下面的代码将适用于您

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:weightSum="100">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="top"
        android:orientation="horizontal" >

        <TextView
            android:id="@+id/folder_name"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:textSize="20sp"
            android:layout_weight="1"
            android:gravity="top|center"
            android:textColor="#115c28"/>

        <TextView
            android:id="@+id/folder_count"
            android:layout_width="0dp"
            android:layout_height="60dp"
            android:textSize="20sp"
            android:textStyle="bold"
            android:textColor="#115c28"
            android:gravity="top|center"
            android:layout_weight="1" />
    </LinearLayout>

    <ListView
        android:id="@+id/folder_display_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

请检查style.xml目录中values文件的保证金值。

它可能会占用你的主题参数。
