AlertDialog 使用

直接上代码吧！

public class AlertDialogUsage extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        new AlertDialog.Builder(AlertDialogUsage.this)
        .setTitle("Powe level")
        .setMessage("Griffin's AlertDialog sample!")
        .setPositiveButton("Yes",
           new DialogInterface.OnClickListener()
            {
           public void onClick(DialogInterface dialoginterface, int i)
             {
        	   Log.d("TAG","[setPositiveButton]");
             }
             }
            )
         .setNegativeButton("No", new DialogInterface.OnClickListener()
            {
           public void onClick(DialogInterface dialoginterface, int i)
             {
        	   Log.d("TAG","[setNegativeButton]");
             }
             }
            )

        .show();
        
    }
}
