MainActivity.java

 

package mars.test;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;

public class MainActivity extends Activity {
	android.widget.Button button1;

	public void onCreate(Bundle savedInstanceState) {

		System.out.println("create");
		super.onCreate(savedInstanceState);
		System.out.println("ffffffffffff");
		setContentView(R.layout.main);

		button1 = (android.widget.Button) this.findViewById(R.id.button1);

		OnClickListener listener = new OnClickListener() {

			@Override
			public void onClick(View v) {
				Intent intent = new Intent();
				intent.setClass(MainActivity.this, Second.class);
				MainActivity.this.startActivity(intent);
			}
		};
		button1.setOnClickListener(listener);
	}

	public void onStart() {
		super.onStart();
		System.out.println("onStart");
	}
	public void onResume() {
		super.onResume();
		System.out.println("onResume");
	}

	public void onPause() {
		super.onPause();
		System.out.println("onPause");
	}

	public void onStop() {
		super.onStop();
		System.out.println("onStop");
	}

	public void onDestory() {
		super.onDestroy();
		System.out.println("onDestory");
	}
}

Second.java

package mars.test;

import android.app.Activity;
import android.os.Bundle;

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

}
