一、效果展示

系統(tǒng)權(quán)限彈框

不再提示后的解釋彈框

跳轉(zhuǎn)到應(yīng)用系統(tǒng)權(quán)限頁面

?

二、代碼實(shí)現(xiàn)

1、設(shè)置權(quán)限

在manifest文件中配置RECORD_AUDIO權(quán)限

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

2、UI

簡單的button按鈕，點(diǎn)擊觸發(fā)動態(tài)申請權(quán)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(quán)限" /></LinearLayout>

3、代碼邏輯
