我希望我的Android应用程序获取EditText值，然后加入＃符号并拨打USSD代码 - 但它只是调用

Question

I want my App to get TextView value add # sign to it and dial USSD code, but the program is just dialing normally and showing the full concatenated text included.

I am using Android 2.0

//To request permission and this work fine, because of its dialing. But I want it to run USSD not dial
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    if(requestCode == REQUEST_CALL){
        if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
            makeCall();
        } else {
            Toast.makeText(this, "permission Denined.", Toast.LENGTH_SHORT).show();
        }
    }
}

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + uSSD +phone+'*'+Amount+NairaSign));
startActivity(intent);

Answer 1

Can you try the following code: Uri.parse("tel:" + uSSD+phone+"*"+Amount+Uri.encode(NairaSign)) NairaSign should have value "#" ie a string variable. make sure to use android.permission.CALL_PHONE in your manifest file.
