要求:页面1跳转到页面2,页面2再返回页面1同时返回数据
页面1添加如下代码:
Intent intent = new Intent(); intent.setClass(页面1.this, 页面2.class); Bundle bundle = new Bundle(); intent.putExtras(bundle);//将Bundle添加到Intent,也可以在Bundle中添加相应数据传递给下个页面,例如:bundle.putString("abc", "bbb"); startActivityForResult(intent, 0);// 跳转并要求返回值,0代表请求值(可以随便写)
页面2接收数据添加代码如下:
Intent intent = this.getIntent();Bundle bundle = intent.getExtras();bundle.putString("aaa", "back");//添加要返回给页面1的数据intent.putExtras(bundle);this.setResult(Activity.RESULT_OK, intent);//返回页面1this.finish();
页面1接收返回数据:(需要重写onActivityResult)
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 0 && resultCode == Activity.RESULT_OK) { Bundle bundle = data.getExtras(); gameView.backString = bundle.getString("aaa"); Toast.makeText(this, backString, Toast.LENGTH_SHORT).show(); } }
