标签:android   http   java   os   使用   io   for   ar   数据   

1.无参数Activity跳转

  Intent it = new Intent(Activity.Main.this, Activity2.class);

  startActivity(it);

  2.向下一个Activity传递数据(使用Bundle和Intent.putExtras)

  Intent it = new Intent(Activity.Main.this, Activity2.class);

  Bundle bundle=new Bundle();

  bundle.putString("name", "This is from MainActivity!");

  it.putExtras(bundle); // it.putExtra(“test”, "shuju”);

  startActivity(it); // startActivityForResult(it,REQUEST_CODE);

  对于数据的获取可以采用:

  Bundle bundle=getIntent().getExtras();

  String name=bundle.getString("name");

  3.向上一个Activity返回结果(使用setResult,针对startActivityForResult(it,REQUEST_CODE)启动的Activity)

  Intent intent=getIntent();

  Bundle bundle2=new Bundle();

  bundle2.putString("name", "This is from ShowMsg!");

  intent.putExtras(bundle2);

  setResult(RESULT_OK, intent);

  4.回调上一个Activity的结果处理函数(onActivityResult)

  @Override

  protected void onActivityResult(int requestCode, int resultCode, Intent data) {

  // TODO Auto-generated method stub

  super.onActivityResult(requestCode, resultCode, data);

  if (requestCode==REQUEST_CODE){

  if(resultCode==RESULT_CANCELED)

  setTitle("cancle");

  else if (resultCode==RESULT_OK) {

  String temp=null;

  Bundle bundle=data.getExtras();

  if(bundle!=null) temp=bundle.getString("name");

  setTitle(temp);

  }

  }

  }

  下面是转载来的其他的一些Intent用法实例(转自javaeye)
