Question

I have the following code in my activity:

......  
DataCell[i] = new TextView(context,null,R.style.TitleRow);
DataCell[i].setText(data[i]);
......

这里是我的风格。

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TitleRow" parent="@android:style/TextAppearance.Medium">
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:textColor">#A0A0A0</item>
        <item name="android:layout_marginTop">5dp</item>
        <item name="android:layout_marginBottom">5dp</item>
        <item name="android:paddingLeft">2dp</item>
        <item name="android:paddingRight">2dp</item>
    </style>
</resources>

No value is getting displayed.. But if I use DataCell[i] = new TextView(context) , its working fine. I know there is some problem with the fact that I am using null for attribute set. But after searching for a long time I am unable to find a perfect example of how to do it. I hope someone could clarify this to me once and for all.

Answer 1

通常,我最终只能建立一个简单的排他性文件,其中要包含我想要即时提出的内容(对你案例的文字意见),该文本适用了适当的风格,并且使用排他性来为我创造榜样。

编外文件:风格_textview.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView ... style="@+style/MyStyle" ... />

法典:

activity.getLayoutInflater().inflate(R.layout.styled_textview, <root_node>, true);

附上您的案文。与此类似:

layout/cell_row.xml

<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    style="@style/TitleRow">

YourActivity.java

......  
LayoutInflater inflater = getLayoutInflater(); // called from activity
......
DataCell[i] = inflater.inflate(R.layout.cell_row, null); 
// or inflater.inflate(R.layout.cell_row, root, false);   where root is a parent view for created TexView 
DataCell[i].setText(data[i]);
......
