Question

我想在两个按钮的两个OnClickListener中使用一个变量。我试图通过验证码验证他的手机号码来注册用户。我想在“验证”按钮的OnClickListener中使用此代码来显示Dilog BoX。如何在这些OnClickListeners中使用此整数变量“verificationCode”。以下是我的代码

package com.deavnet.schoolapp;

import com.deavnet.schoolapp.R;
import com.deavnet.schoolapp.R.layout;
import com.deavnet.schoolapp.R.menu;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.R.string;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
import android.telephony.SmsManager;
import java.util.Random;



public class Verify extends Activity {

    final int verificationCode=0;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.verify_activity);

        // get the References of views
        final  EditText editTextMobileNo =(EditText)findViewById(R.id.editTextMobileNo);
        final EditText editConfirmMobileNo=(EditText)findViewById(R.id.editTextConfirmMobileNo);
        final Button btnSend=(Button)findViewById(R.id.buttonSend);
        final EditText editTextVerificationCode=(EditText)findViewById(R.id.editTextVerificationCode);
        final Button btnVerify=(Button)findViewById(R.id.buttonVerify);


        btnSend.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                String mbno=editTextMobileNo.getText().toString();
                String confirmMbno=editConfirmMobileNo.getText().toString();
                String enteredCode=editTextVerificationCode.getText().toString();
                int verificationCodeEntered= Integer.parseInt(enteredCode);


                if(mbno.equals(""))
                {
                        Toast.makeText(getApplicationContext(), "Field Vaccant", Toast.LENGTH_LONG).show();
                        return;
                }
                else if(mbno!=confirmMbno)
                {
                    Toast.makeText(getApplicationContext(), "Mobile Number do not match", Toast.LENGTH_LONG).show();
                    return;
                }
                else
                {
                    int min = 1000;
                    int max = 9999;
                    Random r = new Random();
                    int i1 = r.nextInt(max - min + 1) + min;

                    int verificationCode = sendSMS(mbno,i1);
                }
            }
        });

        btnVerify.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                String enteredCode=editTextVerificationCode.getText().toString();
                int verificationCodeEntered= Integer.parseInt(enteredCode);
                dilogfun(verificationCodeEntered);
            }
        });
    }
    public int sendSMS(String mbno, int code) {

        try{

        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(mbno, null,""+code+"" , null, null);
        }
        catch(Exception e){
            Log.d("msg error", ""+e.getMessage());
            e.printStackTrace();
        }
        Toast.makeText(getApplicationContext(), "Message Sent!", Toast.LENGTH_LONG).show();
        return code;
    }

    public boolean dilogfun(int verificationCodeEntered)
    {
        if(verificationCode==verificationCodeEntered)
        {
            // Creating alert Dialog with one Button

            AlertDialog alertDialog = new AlertDialog.Builder(
                    Verify.this).create();

            // Setting Dialog Title
            alertDialog.setTitle("Regestration");

            // Setting Dialog Message
            alertDialog.setMessage("Congratcs... Registration Successfull...");

            // Setting Icon to Dialog
            alertDialog.setIcon(R.drawable.tick);

            // Setting OK Button
            alertDialog.setButton("OK",
                    new DialogInterface.OnClickListener() {

                        public void onClick(DialogInterface dialog,
                                int which) {
                            // Write your code here to execute after dialog
                            // closed
                            Toast.makeText(getApplicationContext(),
                                    "Thank You...", Toast.LENGTH_SHORT)
                                    .show();
                        }
                    });

            // Showing Alert Message
            alertDialog.show();
        } 
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.login_activity, menu);
        return true;
    }

}

希望获得最佳效果...... 谢谢

Answer 1

从代码中的以下语句中删除int。

int verificationCode = sendSMS(mbno,i1);

因为您已经在代码的以下语句中全局声明了此变量。

final int verificationCode=0;

删除此int后，此变量也可用于两个侦听器。

修改
