How to show second Activity (Form)

Question

I want to show second activity (Form). I was used the this code to show second activity.

// Code

Intent intent=new Intent(v.getContext(),MainActivity2Activity.class);
startActivityForResult(intent,0);

This code is working fine if i did not add my method. when i click button to show second activity or first activity it is working fine, but the problem when i add my method i got the error say "Unfortunately App Name has stopped".

//My code of first activity are.

public class MainActivity extends ActionBarActivity implements View.OnClickListener {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button btn1=(Button)findViewById(R.id.btnsignup);
    btn1.setOnClickListener(this);

}

@Override
public void onClick(View v) {
    Intent intent=new Intent(v.getContext(),MainActivity2Activity.class);
    startActivityForResult(intent,0);
}

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}
}

// My second activity is

@KaranMer ... you just achive [permutation master achivment](https://en.wikipedia.org/wiki/Programming_by_permutation) ... congratz...(yeah, it is an irony coz it doesn't really matter ... as v.getContext() == MainActivity.this or is a ContextWrapper around MainActivity.this) — Selvin, Aug 06 '15 at 13:31

Do you have any logs to give us ? Please.

You should use native stuff:

Button mButton = (Button) findViewById(R.id.your_button_id_in_the_layout);
Log.d(TAG, " onCreate");
mButton.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent(MainActivity.this, DummyActivity.class);
        startActivity(intent);
    }
});
