本文将通过一个实例讲解怎么实现在4.0及以上系统版本中实现自定义TitleBar,这只是我自己找到的一种方法;
xml布局文件
activity_main.xml
- <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
- xmlns:tools="http://schemas.android.com/tools"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:paddingBottom="@dimen/activity_vertical_margin"
- android:paddingLeft="@dimen/activity_horizontal_margin"
- android:paddingRight="@dimen/activity_horizontal_margin"
- android:paddingTop="@dimen/activity_vertical_margin"
- tools:context=".MainActivity" >
- <TextView
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="@string/hello_world" />
- </RelativeLayout>
自定义的Titlebar的布局文件titlebar.xml
- <?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="48dp"
- android:orientation="horizontal" >
- <ImageView
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_gravity="center"
- android:layout_weight="1.5"
- android:src="@drawable/ic_action_search" />
- <TextView
- android:layout_width="wrap_content"
- android:layout_height="48dp"
- android:layout_weight="1.5"
- android:paddingTop="1dp"
- android:text="@string/app_name"
- android:textSize="14sp" />
- <EditText
- android:id="@+id/searchparameter"
- android:layout_width="wrap_content"
- android:layout_height="48dp"
- android:layout_margin="1dp"
- android:layout_weight="5"
- android:text="ABCDEFGHIJ"
- android:textSize="14sp" />
- <Button
- android:id="@+id/button"
- android:layout_width="wrap_content"
- android:layout_height="48dp"
- android:layout_margin="1dp"
- android:layout_weight="2"
- android:text="OK"
- android:textSize="14sp" />
- </LinearLayout>
为布局文件修改style.xml
此处的style.xml在values-11或者value-14中,否侧会报错:you cannot combine custom titles with other title features
- <?xml version="1.0" encoding="utf-8"?>
- <resources xmlns:android="http://schemas.android.com/apk/res/android">
- <style name="CustomizedWindowTitleBackground">
- <item name="android:background">#047BF0</item>
- </style>
- <style name="titlebarstyle" parent="android:Theme">
- <item name="android:windowTitleSize">48dp</item>
- <item name="android:windowTitleBackgroundStyle">@style/CustomizedWindowTitleBackground</item>
- <!-- All customizations that are NOT specific to a particular API-level can go here. -->
- </style>
- </resources>
在AndroidManifest.xml添加主题样式
android:theme="@style/titlebarstyle"
- <?xml version="1.0" encoding="utf-8"?>
- <manifest xmlns:android="http://schemas.android.com/apk/res/android"
- package="com.example.titlebardemo"
- android:versionCode="1"
- android:versionName="1.0" >
- <uses-sdk
- android:minSdkVersion="8"
- android:targetSdkVersion="17" />
- <application
- android:allowBackup="true"
- android:icon="@drawable/ic_launcher"
- android:label="@string/app_name" >
- <activity
- android:name="com.example.titlebardemo.MainActivity"
- android:label="@string/app_name"
- android:theme="@style/titlebarstyle" >
- <intent-filter>
- <action android:name="android.intent.action.MAIN" />
- <category android:name="android.intent.category.LAUNCHER" />
- </intent-filter>
- </activity>
- </application>
- </manifest>
MainActivity.java中添加实现代码
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
- setContentView(R.layout.activity_main);
- getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
- R.layout.titlebar);
- }
代码中requestWindowFeature(Window.FEATURECUSTOMTITLE);和getWindow().setFeatureInt(Window.FEATURECUSTOMTITLE, R.layout.titlebar);位置是固定的.
希望读者朋友们通过这个例子能够对怎么实现在4.0及以上系统版本中自定义TitleBar有深刻理解和掌握。
