requestWindowFeature(Window.FEATURE_NO_TITLE);
}
privatevoidHideStatusBar(){

requestWindowFeature(Window.FEATURE_NO_TITLE);

样式化的定型对象
Style样式的定义
①新建工程
②定义一个style.xml存放样式
③在string.xml中添加字符串
④修改布局main.xml，添加两个TextView
<?xmlversion="1.0"encoding="utf-8"?>
<resources>
<stylename="myStyle_Text1">
<itemname="android:textSize">25sp</item>
<itemname="android:textColor">#80FF00</item>
</style>
<stylename="myStyle_Text2">
<itemname="android:textSize">18sp</item>
<itemname="android:textColor">#0C688E</item>
<itemname="android:fromAlpha">0.0</item>
<itemname="android:toAlpha">0.0</item>
</style>
</resources>
<?xmlversion="1.0"encoding="utf-8"?>
<resources>
<stringname="string_A">应用myStyle_Text1</string>
<stringname="string_B">应用myStyle_Text2</string>
</resources>
<TextView
android:id="@+id/TextView01"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:text="@string/string_A"></TextView>
<TextView
android:id="@+id/TextView02"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:gravity="center_vertical|center_horizontal"
android:text="@string/string_B"></TextView>

⑤加入Style
⑥结果：
<?xmlversion="1.0"encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
