import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
 
public class MainActivity extends Activity {

	AlarmManager aManager;
	Button start,stop;
	
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        start = (Button)findViewById(R.id.start);
        stop  = (Button)findViewById(R.id.stop);
        
        aManager = (AlarmManager)getSystemService(Service.ALARM_SERVICE);
        
        //指定ChangeService組件
        Intent intent = new Intent(MainActivity.this,ChangeService.class);
        
        //創(chuàng)建PendingIntent對象
        final PendingIntent pi = PendingIntent.getService(
        		MainActivity.this, 0, intent, 0);
        start.setOnClickListener(new OnClickListener() {
			
			public void onClick(View v) {
				// TODO Auto-generated method stub
				aManager.setRepeating(AlarmManager.RTC_WAKEUP, 0, 5000, pi);
				
				start.setEnabled(false);
				
				stop.setEnabled(true);
				Toast.makeText(MainActivity.this, "壁紙定時更換啟動成功", 5000).show();
			}
		});
        
        stop.setOnClickListener(new OnClickListener() {
			
			public void onClick(View v) {
				// TODO Auto-generated method stub
				start.setEnabled(true);
				stop.setEnabled(false);
				
				aManager.cancel(pi);
			}
		});
        
        
    }
