Android 中的Theme和Style使用，还是比较简单的。
1、 首先在res/values/styles.xml的resource中定义三个样式，分别为：
<style name=
"TextView"
>
<item name=
"android:textSize"
>38sp</item>
<item name=
"android:textColor"
>#
128
</item>
<item name=
"android:shadowRadius"
>
1.0
</item>
<item name=
"android:background"
>#
035
</item>
</style>
<style name=
"EditText"
>
<item name=
"android:shadowColor"
>
@android
:color/black</item>
<item name=
"android:shadowRadius"
>
1.0
</item>
<item name=
"android:background"
>#
312
</item>
<item name=
"android:foreground"
>#
432
</item>
<item name=
"android:textAppearance"
>?android:attr/textAppearanceMedium</item>
<item name=
"android:height"
>80dp</item>
</style>
<style name=
"Button"
>
<item name=
"android:background"
>
@android
:drawable/edit_text</item>
<item name=
"android:textAppearance"
>?android:attr/textAppearanceMedium</item>
</style>
|
然后在res/layout文件下的activity_main.xml中的控件中引用刚才定义的Style。
<TextView
android:id=
"@+id/textView1"
style=
"@style/TextView"
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:text=
"@string/hello_world"
/>
<Button
android:id=
"@+id/button1"
style=
"@style/Button"
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:layout_alignLeft=
"@+id/textView1"
android:layout_below=
"@+id/editText1"
android:layout_marginTop=
"18dp"
android:text=
"@string/hello_world"
/>
<EditText
android:id=
"@+id/editText1"
style=
"@style/EditText"
android:layout_width=
"wrap_content"
android:layout_height=
"wrap_content"
android:layout_alignLeft=
"@+id/button1"
android:layout_below=
"@+id/textView1"
android:layout_marginTop=
"19dp"
android:ems=
"10"
android:text=
"@string/hello_world"
/>
|
2、Android的Theme的使用
首先在res/values/themes.xml中定义Theme。
<?xml version=
"1.0"
encoding=
"utf-8"
?>
<resources xmlns:android=
"http://schemas.android.com/apk/res/android"
>
<style name=
"Theme"
parent=
"android:Theme.Light"
>
<item name=
"android:windowFullscreen"
>
true
</item>
<item name=
"android:windowTitleSize"
>60dip</item>
<item name=
"android:windowTitleStyle"
>
@style
/WindowTitle</item>
<item name=
"android:background"
>#
234
</item>
</style>
<style name=
"WindowTitle"
>
<item name=
"android:singleLine"
>
true
</item>
<item name=
"android:shadowColor"
>#
658
</item>
<item name=
"android:shadowRadius"
>
2.75
</item>
</style>
</resources>
|
然后在AndroidManifest.xml中使用刚才定义的主题。
只要定义application的android:theme属性为style/Theme即可。
<application
android:allowBackup=
"true"
android:icon=
"@drawable/ic_launcher"
android:label=
"@string/app_name"
android:theme=
"@style/Theme"
>
<activity
android:name=
"com.example.themedemo.MainActivity"
android:label=
"@string/app_name"
>
<intent-filter>
<action android:name=
"android.intent.action.MAIN"
/>
<category android:name=
"android.intent.category.LAUNCHER"
/>
</intent-filter>
</activity>
</application>
|
也可以用setTheme(R.style.Theme)来调用主题。效果图就不上传了。
