修改Gallery2記錄

 

1. 修改ActionBar的背景色,本例爲修改成紅色#ffff0000，也能夠指定到/res/drawable/xx.png
1). 在Gallery2/res/values/ 增長本身的資源文件theme.xml

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <style name="TestAppTheme" parent="android:Theme.Holo.Light">
            <item name="android:actionBarStyle">@style/WindCustomActionbar</item>
        </style>

        <style name="WindCustomActionbar" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
            <item name="android:background">#ffff0000</item>
        </style>
    </resources>

2). 在AndroidManifest.xml裏指定使用這個Style

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/TestAppTheme">
        ...
    </application>

2. 修改ActionBar上字體顏色，相似上面的，本例修改成白色
1). 在Gallery2/res/values/ 增長本身的資源文件theme.xml

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <style name="TestAppTheme" parent="android:Theme.Holo.Light">
            <item name="android:actionBarStyle">@style/WindCustomActionbar</item>
        </style>

        <style name="WindCustomActionbar" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
            <item name="android:titleTextStyle">@style/WindCustomTitleTextColor</item>
        </style>

        <style name="WindCustomTitleTextColor" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
            <item name="android:textColor">@*android:color/white</item>
        </style>
    </resources>

2). 在AndroidManifest.xml裏指定使用這個Style

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/TestAppTheme">
        ...
    </application>

    
3. 修改選中模式下的ActionBar的背景色，即View.startActionMode後的ActionBar背景色
1). 在Gallery2/res/values/ 增長本身的資源文件theme.xml

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <style name="TestAppTheme" parent="android:Theme.Holo.Light">
            <item name="android:actionModeBackground">@drawable/ic_launcher</item>
        </style>
    </resources>

2). 在AndroidManifest.xml裏指定使用這個Style

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/TestAppTheme">
        ...
    </application>

    
4. 將畫布背景從黑色改成白色
修改文件Gallery2/src/com/android/gallery3d/ui/StaticBackground.java

protected void render(GLCanvas canvas) {
        //canvas.fillRect(0, 0, getWidth(), getHeight(), 0xFF000000);   //0xFF000000爲黑色
        canvas.fillRect(0, 0, getWidth(), getHeight(), 0xFFFFFFFF); //0xFFFFFFFF爲白色
    }

5. 將縮略圖的左邊距，上邊距，右邊距，下邊距設定爲20dp的空隙
Gallery2/src/com/android/gallery3d/app/AlbumSetPage.java

private final GLView mRootPane = new GLView() {
        private final float mMatrix[] = new float[16];


        @Override
        protected void onLayout(
                boolean changed, int left, int top, int right, int bottom) {
           ...


            //mAlbumSetView.layout(0, slotViewTop, slotViewRight, slotViewBottom);  //源代碼
            //加入左邊距，右邊距，上邊距，下邊距
            mAlbumSetView.layout(20, slotViewTop + 20, slotViewRight - 20, slotViewBottom - 20);
            PositionRepository.getInstance(mActivity).setOffset(
                    0, slotViewTop);
        }
        ...
      }

6.將原來的豎屏模式下4行顯示改成3行顯示，修改縮略圖相冊間的間隔
Gallery2/res/values/dimensions.xml

<!-- configuration for album set page -->
    <integer name="albumset_rows_land">2</integer>
    <integer name="albumset_rows_port">4</integer>  <!--將4修改成3 -->
<dimen name="albumset_slot_gap">1dp</dimen>     <!-- 相冊縮略圖的間隙-->
