2022-03-08 动态权限申请

平时关于动态权限申请的写法都比较麻烦，这段时间在网上找到一个关于权限申请的库，使用起来非常方便，所以在这里记录一下。

1.在build.gradle文件中添加其依赖

dependencies {
    //动态权限申请
    implementation 'com.github.dfqin:grantor:2.1.0'
}

2.在AndroidManifest.xml文件中声明你需要使用到的权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />

3.在需要权限申请的地方进行校验，笔者就在主界面创建时进行

//所需动态申请权限列表
private static final int REQUEST_CODE = 1001;
private static final String[] REQUIRED_PERMISSION_LIST = new String[]{
        Manifest.permission.WRITE_EXTERNAL_STORAGE,
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.RECORD_AUDIO,
        Manifest.permission.CAMERA,
        Manifest.permission.READ_PHONE_STATE
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_menu);
    ButterKnife.bind(this);

    permissionCheck();
}

private void permissionCheck() {
    //所需动态申请权限列表
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        System.out.println(android.os.Build.VERSION.SDK_INT + ":申请动态权限");
        PermissionsUtil.requestPermission(this, mPermissionListener, REQUIRED_PERMISSION_LIST);
    } else {
        System.out.println(android.os.Build.VERSION.SDK_INT + ":不需要申请动态权限");
    }
}

PermissionListener mPermissionListener = new PermissionListener() {
    @Override
    public void permissionGranted(@NonNull String[] permission) {
        System.out.println("同意的权限:" + new Gson().toJson(permission));
    }

    @Override
    public void permissionDenied(@NonNull String[] permission) {
        System.out.println("拒绝的权限:" + new Gson().toJson(permission));
    }
};
