android - 密码和 ConfirmPassword 验证 Android 不工作

Question

我有两个页面。我正在尝试通过 Bundle 传递 Password 字段值，并使用 ConfirmPassword 字段检查此值。验证无效。我可以知道什么是实现我的目标的正确方法吗？也许这个问题太基础了，但我没有找到任何合适的解决方案。请帮助我。

这是我的代码:

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

        EditTextUserPass= (EditText) findViewById(R.id.UserHiddenPass);
        EditTextUserPass.setVisibility(View.GONE);

        Imagepassone = (ImageButton) findViewById(R.id.ButtonPassOne);
        Imagepasstwo = (ImageButton) findViewById(R.id.ButtonPassTwo);

        Imagepassone.setOnClickListener(imgButtonHandlerone); 
        Imagepasstwo.setOnClickListener(imgButtonHandlertwo); 


        image = (ImageView) findViewById(R.id.imagefirstpasscode);
        image2 = (ImageView) findViewById(R.id.imagesecondpasscode);
        image3=(ImageView)findViewById(R.id.imagethirdpasscode);
        image4=(ImageView)findViewById(R.id.imagefourpasscode);

    }


    View.OnClickListener imgButtonHandlerone = new View.OnClickListener() {


        public void onClick(View v) { 

            if(v.getId() == R.id.ButtonPassOne) {

                nbStep++;

                changeStepBackground(nbStep);
            }
        }
   };
   public void changeStepBackground(int i) { 
        // four step switch
        switch(i) {
            case 1:
                image.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("1");

            break;
            case 2:
                image2.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("1");
            break;
            case 3:
                image3.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("1");
            break;
            case 4:
                image4.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("1");
            break;


        }
    }

   View.OnClickListener imgButtonHandlertwo = new View.OnClickListener() {



    public void onClick(View v) { 

           if(v.getId() == R.id.ButtonPassTwo) {

               nbStep++;

               changeStepBackground2(nbStep);
           }
       }
  };
  public void changeStepBackground2(int i) { 

        switch(i) {
            case 1:
                image.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("2");
            break;
            case 2:
                image2.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("2");
            break;
            case 3:
                image3.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("2");
            break;
            case 4:
                image4.setImageResource(R.drawable.passselect);
                EditTextUserPass.setText("2");
            break;


        }
    }

}
    @Override
    public void onBackPressed() {
       moveTaskToBack(true); 
       UserPasscode.this.finish();
    }

    public void gotoconfirmpasscode(View v)

    {
        String UserPass=EditTextUserPass.getText().toString();  
        int numberOfImages=nbStep;
        if(numberOfImages!=4)
        {   
        }
        else
        { 

             Bundle b = new Bundle();
             b.putString("PASSWORD", UserPass);

        Intent intent = new Intent(UserPasscode.this,UserConfirmPasscode .class);
        intent.putExtras(b);
        startActivity(intent);
        }       

    }
}

Answer 1

字符串比较错误。始终将 String 与 .equals() 方法进行比较。改变这个:

if(venName!=UserPass)

为此:

System.out.println("venName :: "+venName);
System.out.println("UserPass :: "+UserPass);
if(!venName.equals(UserPass))
