Chapter 3 - <Orientations> program

kcoste · October 21st, 2011, 04:23 PM

The Chapter 3 "Orientations" program seems to do absolutely nothing!?

I checked both .zip files (all code, and chapter 3 only) and MainActivity.java is empty in both.

My main concern is using the TableLayout, both statically and programmatically.

Am I simply missing something (new to Android, coming from C++/C#, etc)? Was there supposed to be a 4th example in Chapter 3?

Both other Chapter 3 examples seem to work fine but demonstrate little or nothing about TableLayout.

Is there a working example using TableLayout later in the book?

Thanks in advance

Obviously not much help, but it does appear that the MainActivity.java file is empty in the sample code.

Not done the chapter 3 stuff yet so I can't help with the other question.

Haven't tried either yet, but I found this at Stack Overflow:

Which led to this (way down at the bottom):

looks just right for my purposes

Code:

package com.xyz.orientations; // don't forget to fix this to whatever your package name is!!

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class MainActivity extends Activity
	{
/**Called when the activity is first created.*/
	@Override
	public void onCreate(Bundle savedInstanceState)
		{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
        Log.d("StateInfo", "onCreate");
		}
	@Override
    public void onStart()
		{
        Log.d("StateInfo", "onStart");
        super.onStart();
		}
    @Override
    public void onResume()
    	{
        Log.d("StateInfo", "onResume");
        super.onResume();
    	}
    @Override
    public void onPause()
    	{
        Log.d("StateInfo", "onPause");
        super.onPause();
    	}
    @Override
    public void onStop()
    	{
        Log.d("StateInfo", "onStop");
        super.onStop();
    	}
    @Override
    public void onDestroy()
    	{
        Log.d("StateInfo", "onDestroy");
        super.onDestroy();
    	}
    @Override
    public void onRestart()
    	{
        Log.d("StateInfo", "onRestart");
        super.onRestart();
    	}
	}
