Application has stopped unexpectedly , please try again error

On clicking of textview of Loginform i was redering the page towards my Registration form.

It was working fine before writting code in registration form. But suddenly (After writting code in Registration form) , it started giving me above error after clicking on textview ("Please register yourself") in loginform.

After viewing logcat, i came to know that error is on Registration page.

Here is code on my registration page:

public class Register extends Activity implements OnClickListener,OnCheckedChangeListener {

    String gender=null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);

        //Toast.makeText(getApplicationContext(),"Load" , Toast.LENGTH_LONG).show();

        Button btnRegister =(Button)findViewById(R.id.link_to_login);

        final EditText edFullName=(EditText)findViewById(R.id.txtfname);
        final EditText edUserName=(EditText)findViewById(R.id.txtusername);
        final EditText edEmail=(EditText)findViewById(R.id.txtemail);
        final RadioButton rbMale=(RadioButton)findViewById(R.id.rd_male);
        final RadioButton rbFeMale=(RadioButton)findViewById(R.id.rd_female);
        final EditText edDateOfBirth=(EditText)findViewById(R.id.txtdob);
        final EditText edPassward=(EditText)findViewById(R.id.txtpassword);

        rbFeMale.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
                // TODO Auto-generated method stub

                if(arg1==true)
                {
                    gender="Female";
                }
            }
        });


        rbMale.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
                // TODO Auto-generated method stub

                if(arg1==true)
                {
                    gender="Male";
                }
            }
        });

        final  AlertDialog ad=new AlertDialog.Builder(this).create();
        btnRegister.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                CallSoap cs=new CallSoap();
                try
                {
                    Boolean result=cs.Register(edFullName.getText().toString(), edUserName.getText().toString(), edEmail.getText().toString(), gender, edDateOfBirth.getText().toString(), edPassward.getText().toString());
                    if (result==true)
                    {
                        Toast.makeText(getApplicationContext(),"Registered Sucessfully!!!" , Toast.LENGTH_LONG).show();
                    }
                }
                catch(Exception ex)
                {
                    ad.setMessage(ex.getMessage());
                }


            }
        });

        TextView tvBackLogin=(TextView)findViewById(R.id.link_to_login);
        tvBackLogin.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                Intent intent = new Intent(Register.this,MainActivity.class);
                //intent.putExtra(EXTRA_MESSAGE, etLoginID.getText().toString());
                startActivity(intent);

            }
        });



    }

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

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // TODO Auto-generated method stub

    }

}

You have this

  <TextView // text view with id link_to_login
        android:id="@+id/link_to_login"

While initializing you have this

  Button btnRegister =(Button)findViewById(R.id.link_to_login);

Hence you get class cast exception

Either change your textview to button

  <Button 
    android:id="@+id/link_to_login"

or 

  TextView btnRegister =(TextView)findViewById(R.id.link_to_login);

THis is because

android:id="@+id/link_to_login" is for TextView and in your code you have declared it for Button... So change it..

Hope you understand...And this will help you....

In xml you have defined it as TextView and in onCreate you are assigning it as button which is causing classCastexception. Change it in xml/code and it should work
