【Susen】EasyPermissions

https://github.com/googlesamples/easypermissions

• app目录下build.gradle添加依赖库：EasyPermissions版本

dependencies {
    // 运行时权限
    implementation 'pub.devrel:easypermissions:1.0.1'
}

• AndroidManifest.xml中添加功能所需权限：Android运行时权限列表

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

• 实现权限回调接口

implements EasyPermissions.PermissionCallbacks

• 使用方法

private static final int PRC_CALENDAR = 0;// 权限请求码：日历

@AfterPermissionGranted(PRC_CALENDAR)
private void requestPermissions() {// 此方法不能带参数
    String[] perms = {Manifest.permission.READ_CALENDAR, Manifest.permission.WRITE_CALENDAR};
    // EasyPermissions方法：检测权限
    if (EasyPermissions.hasPermissions(this, perms)) {
        Toast.makeText(this, "正在打开系统日历...", Toast.LENGTH_SHORT).show();// TODO
    } else {
        // EasyPermissions方法：请求权限
        EasyPermissions.requestPermissions(this, "请授予「日历」所需要的相关权限！", PRC_CALENDAR, perms);
    }
}

// 请求权限结果回调
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    // EasyPermissions方法：处理请求权限结果
    EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
}

// EasyPermissions回调：权限被授予
@Override
public void onPermissionsGranted(int requestCode, List<String> perms) {
}

// EasyPermissions回调：权限被拒绝
@Override
public void onPermissionsDenied(int requestCode, List<String> perms) {
    if (requestCode == PRC_CALENDAR) {
        Toast.makeText(this, "您拒绝了「日历」所需要的相关权限！", Toast.LENGTH_SHORT).show();
    }
}
