Switching between app views on Android

I have a button created on my main (activity) using . I set an onClick() method to determine the actions of the button. I want to display another view on clicking the button. The android:onclick("") call uses a string parameter. How can i reference the other view? I have its xml activity and content files built and the java file is properly put together and tested on my sdk to be working. But, how should i call the new object's view? I tried calling getApplication() but it crashes the app. I'll appreciate any assistance.

Here is what i tried:

public void onClick(View v) {
    // TODO Auto-generated method stub
    Toast.makeText(getApplicationContext(), "I'm clicked!", Toast.LENGTH_SHORT).show();
    AppActivity app = new AppActivity();
    getApplicationContext().stopService(new Intent());
    app.getApplicationContext().startActivity(new Intent());
}

If you want to change activities use this:

Intent myIntent = new Intent(this, AvitivityName.class);
startActivity(myIntent);

If you just want to change views, use:

setContentView(R.layout.myXML);

in your onCreate.

If you want to pass data between activities, use putExtra and getExtra:

Intent i=new Intent(context,SendMessage.class);
i.putExtra("Hi", user.getUserAccountId()+"");
context.startActivity(i);

and to get:

Intent i= getIntent();
i.getExtra("Hi");

Let me know if this helped.

You have to save your current Activity context somewhere and then use it to call the new activity:

private Context ctx;
public Class CurrentActivity extends Activity{
    // let's save it in your onCreate method
    onCreate(Bundle savedBundleState){
       ctx = this;
    } 

    // now on your onClick method
    public void onClick(View v) {
      // TODO Auto-generated method stub
      Toast.makeText(ctx, "I'm clicked!", Toast.LENGTH_SHORT).show();
      Intent intent = new Intent(ctx, AppActivity.class);
      ctx.startActivity(intent);
    }

}
