Android 11 运行时存储权限

如何解决Android 11 运行时存储权限

Android 11 (R) 跳过我的许可请求，但所有工作都在未经许可的情况下进行。我在下面给出了我的代码。我尝试了很多代码，但无法正常工作。请帮帮我

I need this type of permission dialog

     int m_permit = ActivityCompat.checkSelfPermission(activity,Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (m_permit != PackageManager.PERMISSION_GRANTED){

        Permission(context);
    }




public void Permission(Context context) {

    final Dialog dialog;

    final Activity activity = (Activity) context;


    LayoutInflater li = LayoutInflater.from(context);

        View view= li.inflate(R.layout.dialog_permission,null);
        dialog = new Dialog(context,R.style.Theme_AppCompat_Light_Dialog);
        dialog.setContentView(view);

        TextView ok = view.findViewById(R.id.ok);
        dialog.show();

        ok.setonClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                dialog.dismiss();

                int m_permit = ActivityCompat.checkSelfPermission(activity,Manifest.permission.WRITE_EXTERNAL_STORAGE);

                if (m_permit != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions(activity,STORAGE_PERMISSION,1);
                }
            }
        });
}
