activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

    xmlns:tools="http://schemas.android.com/tools"

        android:layout_width="match_parent"

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_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"/>

效果:
