如何制作自定义的短信权限对话框

基本上你可以创建一个 AlertDialog 在这里添加描述。下面是一个如何实现这一目标的例子

try {
    new android.app.AlertDialog.Builder(activity)
            .setMessage("Your description about the permission")
            .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    String[] permissions = {Manifest.permission.SEND_SMS};
                    requestPermissions(permissions, PERMISSION_REQUEST_CODE);
                }
            })
            .create()
            .show();
} catch (Exception e) {
    // handle exception in case context is not present / destroyed, etc
}

或者,您可以让用户在没有任何权限的情况下发送短信。在您的 Activity

private boolean sendSms(final String phoneNumber, final String content) {
    Uri uri = Uri.parse("smsto:" + phoneNumber);
    Intent intent = new Intent(Intent.ACTION_SENDTO, uri);
    if (isIntentAvailable(intent)) {
        intent.putExtra("sms_body", content);
        startActivity(intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
        return true;
    }
    return false;
}

private boolean isIntentAvailable(final Intent intent) {
    return getPackageManager()
            .queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
            .size() > 0;
}
