Question

i have this code but every time i run the app and click on my button it crashes and i don’t get why.. am i doing something wrong here any help would be great thanks

im trying to got to the “Sec.class” page/class

public class APPcalendarActivity extends Activity implements OnClickListener{
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        View continueButton = findViewById(R.id.continue_button);
        continueButton.setOnClickListener( (OnClickListener) this);
    }

    //@Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
        case R.id.continue_button:
            Intent i = new Intent(this, Sec.class);
            startActivity(i);           
            break;
        }

    }

THIS IS WHAT I WAS MISSING IN THE MANISFEST.XML FILE

and i want to slap the person who downgraded my question

 <activity android:name=".Sec"
android:label="@string/sec" >
</activity>

Answer 1

Check that you’ve declared an <activity> tag for the Sec activity in your AndroidManifest.xml.

But posting (or simply reading) the crash stacktrace from logcat would be more instructive.
