Android App Development ฉบับสมบูรณ์

2. สร้างไฟล์ GamePlayerActivity.java และเขียนโค้ด Java ดังนี้
package com.android.example.xogame;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class GamePlayerActivity extends Activity {
int player = 0;
EditText player1;
EditText player2;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.palyer);
Bundle extras = getIntent().getExtras();
if(extras !=null) {
player = extras.getInt("PLAYER");
}
player1 = (EditText) findViewById(R.id.editText_player1);
player2 = (EditText) findViewById(R.id.editText_player2);
if(player==1){
player2.setText("android");
}
Button bt_back = (Button) findViewById(R.id.button_back);
Button bt_start = (Button)findViewById(R.id.button_start);
bt_back.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
finish();
}
});
bt_start.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(getBaseContext(),XOGameActivity.class);
intent.putExtra("PLAYER", player);
intent.putExtra("PLAYER_ONE_NAME", player1.getText().toString());
intent.putExtra("PLAYER_TWO_NAME", player2.getText().toString());
startActivity(intent);
}
});
}
}
