my listview.xml

我的列表视图.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/RelativeLayout01"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" xmlns:myapp="http://schemas.android.com/apk/res/zaid.quotes.dlama">
    <ListView android:id="@+id/ListView01" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:layout_alignParentTop="true"
        android:layout_marginBottom="50dp" android:paddingTop="50dp"></ListView>
    <Button android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:id="@+id/Back"
        android:layout_alignParentBottom="true" android:text="Go Back"></Button>

    <LinearLayout android:layout_width="wrap_content"
        android:id="@+id/LinearLayout01" android:layout_height="wrap_content"
        android:layout_alignParentTop="true">
        <com.admob.android.ads.AdView android:id="@+id/ad"
            android:layout_width="fill_parent" android:layout_height="wrap_content"
            myapp:backgroundColor="#000000" myapp:primaryTextColor="#FFFFFF"
            myapp:secondaryTextColor="#CCCCCC" android:layout_alignParentTop="true" />
    </LinearLayout>


</RelativeLayout>

the current size of the text in the listview is large. and i cant seem to figure out how to change the text size.

列表视图中文本的当前大小很大。我似乎无法弄清楚如何更改文本大小。

What really matters here is the row Viewyou return in BaseAdapter's getView(..)or CursorAdapter's newView(..).

这里真正重要的是View您在BaseAdapter'sgetView(..)或CursorAdapter's 中返回的行newView(..)。

You can copy simple_list_item_1.xmlor simple_list_item_2.xmlfrom Android sources and customize it to your needs.
Say, change
android:textAppearance="?android:attr/textAppearanceLarge"
to
android:textAppearance="?android:attr/textAppearanceMedium".

您可以复制simple_list_item_1.xml或simple_list_item_2.xml从 Android 源中复制并根据您的需要对其进行自定义。
说，
android:textAppearance="?android:attr/textAppearanceLarge"
改为
android:textAppearance="?android:attr/textAppearanceMedium"。

The other option is to change text appearance right in the Adapterby calling setTextAppearance(context, android.R.attr.textAppearanceMedium)on the TextView.

另一种选择是改变文本外观正确Adapter调用setTextAppearance(context, android.R.attr.textAppearanceMedium)的TextView。

I'm not sure if I'm getting what you want, but a listView doesn't have text size, the elements inside it are the ones that will define their text size.

我不确定我是否得到了您想要的东西，但是 listView 没有文本大小，其中的元素将定义其文本大小。

That is, if you add a textview to the list, define the text size in the textView.

也就是说，如果在列表中添加一个 textview，则在 textView 中定义文本大小。

Yanchenko's answer works perfect, if you rename your local simple_list_item_1.xml

Yanchenko 的回答很完美，如果你重命名你的本地 simple_list_item_1.xml

MyActivity.java:

MyActivity.java：

ArrayAdapter<String> filesAdapter = new ArrayAdapter<String>(this, 
    R.layout.simplest_list_item_1, topFilesArray);
filesList.setDivider(null);

simplest_list_item_1.xml:

simplest_list_item_1.xml：

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="7pt"
    android:paddingLeft="6dip" />

layout_height="wrap_content"is used here for 10 list items only.

layout_height="wrap_content"此处仅用于 10 个列表项。

I think you have the wrong approach to using a ListView. Use an adapter to feed the list to the view, and in the ListView layout file, you don't define the rows, you only define the listview itself and a default textview which will show when there are no items in the list. Then you define a separate xml file which will render each row. Then in this row layout you're free to set the text size as you wish.

我认为您使用 ListView 的方法是错误的。使用适配器将列表提供给视图，在 ListView 布局文件中，您不定义行，您只定义列表视图本身和默认文本视图，该文本视图将在列表中没有项目时显示。然后定义一个单独的 xml 文件，它将呈现每一行。然后在此行布局中，您可以随意设置文本大小。

Here's an example of the listview xml (notice the special id's given to the listview and textview, these ARE required):

下面是一个 listview xml 的例子（注意给了 listview 和 textview 的特殊 id，这些是必需的）：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:scrollbars="horizontal" android:orientation="vertical"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:paddingLeft="8dp" android:paddingRight="8dp">

    <ListView android:id="@+id/android:list" android:layout_width="fill_parent"
        android:layout_height="fill_parent" android:layout_weight="1"
        android:drawSelectorOnTop="false" />

    <TextView android:id="@+id/android:empty"
        android:layout_width="fill_parent" android:layout_height="fill_parent"
        android:text="No records found" />
</LinearLayout>

Then your row layout would be your file without the listview:

那么你的行布局将是没有列表视图的文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/RelativeLayout01"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android" xmlns:myapp="http://schemas.android.com/apk/res/zaid.quotes.dlama">
    <Button android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:id="@+id/Back"
        android:layout_alignParentBottom="true" android:text="Go Back"></Button>

    <LinearLayout android:layout_width="wrap_content"
        android:id="@+id/LinearLayout01" android:layout_height="wrap_content"
        android:layout_alignParentTop="true">
        <com.admob.android.ads.AdView android:id="@+id/ad"
            android:layout_width="fill_parent" android:layout_height="wrap_content"
            myapp:backgroundColor="#000000" myapp:primaryTextColor="#FFFFFF"
            myapp:secondaryTextColor="#CCCCCC" android:layout_alignParentTop="true" />
    </LinearLayout>
</RelativeLayout>

And here's a sample of the adapter's getView() method where you will set the row layout file:

这是适配器的 getView() 方法的示例，您将在其中设置行布局文件：

public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.row_layout, null);
        }
            //Now, assuming your adapter has the list of objects to be displayed in 'records':
            if(records != null) {
                    YourRecord r = records.get(position);
                    if(r != null) {
                            // Populate your views in your row.xml based on data from your record selected (r)
                    }
                    ...
             }

}
