AndroidManifest.xml中Activity ConfigChanges属性的用法
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
?通過設置這個屬性可以使Activity捕捉設備狀態變化,以下是可以被識別的內容: ?
CONFIG_FONT_SCALE
CONFIG_MCC
CONFIG_MNC
CONFIG_LOCALE
CONFIG_TOUCHSCREEN
CONFIG_KEYBOARD
CONFIG_NAVIGATION
CONFIG_ORIENTATION
設置方法:將下列字段用“|”符號分隔開,例如:“ locale|navigation|orientation
”
| Value | Description |
| “mcc“ | The IMSI mobile country code (MCC) has changed — that is, a SIM hasbeen detected and updated the MCC.移動國家號碼,由三位數字組成,每個國家都有自己獨立的MCC,可以識別手機用戶所屬國家。 |
| “mnc“ | The IMSI mobile network code (MNC) has changed — that is, a SIM hasbeen detected and updated the MNC.移動網號,在一個國家或者地區中,用于區分手機用戶的服務商。 |
| “locale“ | The locale has changed — for example, the user has selected a new language that text should be displayed in.用戶所在地區發生變化。 |
| “touchscreen“ | The touchscreen has changed. (This should never normally happen.) |
| “keyboard“ | The keyboard type has changed — for example, the user has plugged in an external keyboard.鍵盤模式發生變化,例如:用戶接入外部鍵盤輸入。 |
| “keyboardHidden“ | The keyboard accessibility has changed — for example, the user has slid the keyboard out to expose it.用戶打開手機硬件鍵盤 |
| “navigation“ | The navigation type has changed. (This should never normally happen.) |
| “orientation“ | The screen orientation has changed — that is, the user has rotated the device.設備旋轉,橫向顯示和豎向顯示模式切換。 |
| “fontScale“ | The font scaling factor has changed — that is, the user has selected a new global font size.全局字體大小縮放發生改變 |
? View Code XML
| <manifest?xmlns:android="http://schemas.android.com/apk/res/android" ? ?? ?package="com.androidres.ConfigChangedTesting" ? ?? ?android:versionCode="1" ? ?? ?android:versionName="1.0.0"> ? ??<application?android:icon="@drawable/icon"?android:label="@string/app_name"> ? ?? ???<activity?android:name=".ConfigChangedTesting" ? ?? ?? ?? ?? ?? ?android:label="@string/app_name" ? ?? ?? ?? ?? ?? ?android:configChanges="keyboardHidden|orientation"> ? ?? ?? ?? ?<intent-filter> ? ?? ?? ?? ?? ??<action?android:name="android.intent.action.MAIN"?/> ? ?? ?? ?? ?? ??<category?android:name="android.intent.category.LAUNCHER"?/> ? ?? ?? ?? ?</intent-filter> ? ?? ???</activity> ? ??</application> </manifest> |
在Activity中添加了 android:configChanges屬性,目的是當所指定屬性(Configuration Changes)發生改變時,通知程序調用 onConfigurationChanged()函數
