Textview causing java.lang.ClassCastException: android.widget.TextView

I have three textviews and applied clickevent on them, but when i click on any of them the they cause Forceclose error in application. i have also tried changing ids textviews and then clean project and ran the project still that error is not removed.

My XML code is

for one textview

<LinearLayout
        android:id="@+id/LL_fb" 
        android:layout_width="180px"
        android:layout_height="27px"
        android:layout_above="@+id/txt_msg_regs"
        android:layout_alignLeft="@+id/LL_signup"
        android:layout_marginBottom="25dp"
        android:background="@drawable/facebook" >        
    <TextView
        android:id="@+id/btn_txt_fb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Connect with facebook"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="23dp"
        android:layout_marginTop="1dp"
        android:clickable="true"
        android:textColor="#FFFFFF" />
    </LinearLayout>

for second textview

<LinearLayout 
        android:id="@+id/LL_signup"
        android:layout_width="180px"
        android:layout_height="29px"
        android:layout_above="@+id/textView1"
        android:layout_alignLeft="@+id/LL_login"
        android:background="@drawable/lmyic_signup">

    <TextView
        android:id="@+id/btn_txt_sinup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="signup with email"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="25dp"
        android:layout_marginTop="1dp"
        android:clickable="true"
        android:textColor="#FFFFFF" />

    </LinearLayout>

for third one

 <LinearLayout 
            android:id="@+id/LL_login"
            android:layout_width="180px"
                android:layout_height="29px"
                android:layout_alignParentBottom="true"
                android:layout_centerHorizontal="true"
                android:layout_marginBottom="69dp"
                android:background="@drawable/lmyic_login">
        <TextView
            android:id="@+id/btn_txt_login"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Log in"
            android:layout_gravity="center_vertical"
            android:layout_marginLeft="70dp"
            android:layout_marginTop="1dp"
            android:textColor="#FFFFFF" 
            android:clickable="true"/> 
        </LinearLayout>

this is my android code. This class name in intent are also correct and i verified them.

TextView img_login;
img_login = (TextView)findViewById(R.id.btn_txt_login);
 img_login.setOnClickListener(new OnClickListener() {

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

                if(v.getId() == img_login.getId())
                {
                Intent i_lin = new Intent(LockmeifyoucanActivity.this,lmiyc_login.class);
                startActivity(i_lin);
                }                   
            }
        });

Please Tell me what is wrong with this. If logcat is needed then ask me for it....

if you have duplicate resource Id, that will throw ClasscastException. So make sure you don't have duplicate element id throughout the whole project.

these are lines from 42-48 

 setContentView(R.layout.lmyic_login_page);                 
  txtBack = (TextView)findViewById(R.id.ImgViewTxtBack);          txtBack.setTypeface(null,Typeface.BOLD);
   iv_login = (ImageView)findViewById(R.id.Txtlogin);
   iv_login.setOnClickListener(this);
   iv_sign_up = (ImageView)findViewById(R.id.TxtSignup);

I think problem is with iv_login = (ImageView)findViewById(R.id.Txtlogin); – Dheeresh Singh 1 min ago edit because this is 46 line and it should be textview and you are castin it in Imageview – Dheeresh Singh just now edit

you have some problem with textview in lmiyc_login activity.in lmiyc_login corrent line number 46 which maybe:

TextView txtview;
txtview = (TextView)yourlayout.findViewById(R.id.txtviewid);

To resolve this error quickly, set one break point at line: 

View view = findViewById(R.id.btn_txt_login);

Then, see on locals tab which component is, looking at gen/R.java.

change ur code with this

TextView img_login;
 img_login = (TextView)findViewById(R.id.txt_login);
   img_login.setOnClickListener(new OnClickListener() {

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

            if(v.getId().equals(img_login.getId()))
            {
            Intent i_lin = new Intent(LockmeifyoucanActivity.this,lmiyc_login.class);
            startActivity(i_lin);
            }                   
        }
    });

Please post the complete XMl so that we can view the btn_txt_login in that.

It looks it is button because "findViewById(R.id.btn_txt_login);" would return null if this "btn_txt_login" id is not in xml.

Wrong resource ID...

img_login = (TextView)findViewById(R.id.btn_txt_login);

according to your XML should be

img_login = (TextView)findViewById(R.id.txt_login);

etc..

findViewById(R.id.btn_txt_login);

Is this really a TextView or do you have a Button in your layout as well? I think you're trying to cast a Button to a TextView
