一、效果展示

系統權限彈框

不再提示后的解釋彈框

跳轉到應用系統權限頁面

?

二、代碼實現

1、設置權限

在manifest文件中配置RECORD_AUDIO權限

<uses-permission android:name="android.permission.RECORD_AUDIO" />

2、UI

簡單的button按鈕，點擊觸發動態申請權限邏輯

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center"android:orientation="vertical"><Buttonandroid:id="@+id/btPermission"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="請求mic權限" /></LinearLayout>

3、代碼邏輯
