在Marshmallow中,如何像Hangouts一样逐个提示两个或多个权限对话框呢？

Question

我正在处理我的应用程序代码以在Marshmallow设备中工作,我正在管理其权限对话框以显示在需要的位置.

目前在这种情况下,它需要两个权限(位置和存储),我想逐个询问Hangout的工作方式.无法找到它的定制方式,任何解决方案？

这是我为单一权限处理的代码:

case REQUEST_CODE_WRITE_EXTERNAL_STORAGE: {

    if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
        /Permission is granted
        Toast.makeText(this, "SDK >= 23 & permission Granted ", Toast.LENGTH_SHORT).show();
        return true;

    } else {
        //Permission is revoked
        ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE}, REQUEST_CODE_WRITE_EXTERNAL_STORAGE);
        return false;
    }
}

并在onRequestPermissionsResult():

case REQUEST_CODE_WRITE_EXTERNAL_STORAGE: {

    // If request is cancelled, the result arrays are empty.
    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

        // permission was granted, yay! Do the
        // contacts-related task you need to do.
        Log.e("PMS", "granted");
        Toast.makeText(this, "SDK >= 23 & permission Granted ", Toast.LENGTH_SHORT).show();

    } else {
        Log.e("PMS", "Not Granted");

        // permission denied, boo! Disable the
        // functionality that depends on this permission.
        int checkStatus = getPermissionStatus(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (checkStatus == 3) {
            Toast.makeText(this, "SDK  >= 23 & permission Denied ", Toast.LENGTH_SHORT).show();

        } else if (checkStatus == 4) {
            Toast.makeText(this, "SDK  >= 23 & permission Blocked ", Toast.LENGTH_SHORT).show();

        }
    }
    return;
}

如果要一一请求多个权限，需要在第二个参数String[] ActivityCompat.requestPermissions方法中添加所有权限。像这样：

ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.ACCESS_COARSE_LOCATION}, REQUEST_CODE_WRITE_EXTERNAL_STORAGE);

如果有帮助请告诉我
