1.在Resources——values下新建styles.xml,新增內容如下:
<resources xmlns:android="http://schemas.android.com/apk/res/android"> <style name="AppTheme" parent="@android:style/Theme"> <item name="android:windowNoTitle">true</item> <!-- 設定沒有標題 --> <item name="android:textSize">20sp</item> <!-- 設定文字大小 --> <item name="android:textColor">#F34141</item> <item name="android:background">@android:color/background_light</item> <!-- 設定activity切換動畫 --> <item name="android:windowAnimationStyle">@style/activityAnimation</item> </style> <!-- animation 樣式 --> <style name="activityAnimation" parent="@android:style/Animation"> <item name="android:activityOpenEnterAnimation">@anim/slide_right_in</item> <item name="android:activityCloseExitAnimation">@anim/slide_right_out</item> <item name="android:activityOpenExitAnimation">@anim/slide_left_out</item> <item name="android:activityCloseEnterAnimation">@anim/slide_left_in</item> </style> </resources>
2.在Resources下新建資料夾anim,在這個新建的資料夾下面新建四個檔案,分別是
(1)slide_left_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:duration="300" android:fromXDelta="-100.0%p" android:toXDelta="0.0" />
</set>
(2)slide_left_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:duration="300" android:fromXDelta="0.0" android:toXDelta="-100.0%p" />
</set>
(3)slide_right_in.xml
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <translate android:duration="300" android:fromXDelta="100.0%p" android:toXDelta="0.0" /> </set>
(4)slide_right_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:duration="300" android:fromXDelta="0.0" android:toXDelta="100.0%p" />
</set>
3.修改AndroidManifest.xml檔案(紅色標註的部分)
<application android:theme="@style/AppTheme"></application>
4.在MainActivity.cs中的切換按鈕的程式碼:
button.Click += delegate
{
Intent intent = new Intent();
intent.SetClass(this, typeof(Activity2));
StartActivity(intent);
OverridePendingTransition(Resource.Animation.slide_left_in, Resource.Animation.slide_right_out);
};
