WIFI热点 UA9分析 (接UA3 往下)
UA9 操作列
- UA编号 UA9
- UA说明 ** WIFI移动热点详细设置界面弹框确认按钮**
- UA触发函数 WifiApDialog.java 的 onCreate 函数 设置了 点击保存按钮处理事件
setButton(BUTTON_SUBMIT, context.getString(R.string.wifi_save), DialogInterface.OnClickListener mListener【TetherSettings.java实现该接口】); -
UA字符可选值 【设置WLAN热点【移动热点设置】】
- UA布局及ID 在network_and_internet.xml布局文件的Preference指定了Fragment android:fragment=”com.android.settings.TetherSettings” 当前所在的Fragment TetherSettings 当前的UI为 Activity: [NetworkDashboardActivity] SettingsActivity.java 实现了 OnPreferenceStartFragmentCallback 接口 Fragment:TetherSettings
