activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.loaderman.permissionsdemo.MainActivity"> <Button android:onClick="requestSingle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="申请单个权限"/> <Button android:onClick="requestMulti" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="申请多个权限"/> <FrameLayout android:id="@+id/sample_content_fragment" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout>
在values下创建array.xml
<?xml version="1.0" encoding="utf-8"?> <resources> <string-array name="permissions"> <item>@string/permission_recode_audio_hint</item> <item>@string/permission_get_accounts_hint</item> <item>@string/permission_read_phone_hint</item> <item>@string/permission_call_phone_hint</item> <item>@string/permission_camera_hint</item> <item>@string/permission_access_fine_location_hint</item> <item>@string/permission_access_coarse_location_hint</item> <item>@string/permission_read_external_hint</item> <item>@string/permission_white_external_hint</item> </string-array> </resources>
在String.xml下添加字符串信息
<resources> <string name="app_name">PermissionsDemo</string> <string name="permission_get_accounts_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_GET_ACCOUNTS</string> <string name="permission_read_phone_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_READ_PHONE_STATE</string> <string name="permission_call_phone_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_CALL_PHONE</string> <string name="permission_camera_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_CAMERA</string> <string name="permission_access_fine_location_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_ACCESS_FINE_LOCATION</string> <string name="permission_access_coarse_location_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_ACCESS_COARSE_LOCATION</string> <string name="permission_read_external_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_READ_EXTERNAL_STORAGE</string> <string name="permission_white_external_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_WRITE_EXTERNAL_STORAGE</string> <string name="permission_recode_audio_hint">没有此权限,无法开启这个功能,请开启权限。PERMISSION_RECORD_AUDIO</string> </resources>
清单文件添加权限:
<uses-permission android:name="android.permission.CAMERA"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.CALL_PHONE"/> <uses-permission android:name="android.permission.SEND_SMS"/> <uses-permission android:name="android.permission.READ_SMS"/> <uses-permission android:name="android.permission.GET_ACCOUNTS"/> <uses-permission android:name="android.permission.READ_PHONE_STATE"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.RECORD_AUDIO"/>
