android开发之Intent传参

两个Activity之间想要传递参数，并且获得返回值，就要用到startactivityforresult（intent，requecode）这个方法了 Intent intent = new Intent(StartGameActivity.this,GameSettingActivity.class); startActivityForResult(intent,REQUESTCODE); break;然后重写 onActivityResult方法 protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == REQUESTCODE &&resultCode == RESULTCODE){ if(data!=null){ bgMusic = data.getStringExtra("bgMusic"); sound = data.getStringExtra("sound"); planetype = data.getStringExtra("planetype"); Toast.makeText(StartGameActivity.this,"音乐是："+bgMusic+"，音效是:"+sound+"，机型是："+planetype,Toast.LENGTH_SHORT).show(); }在另一个Activity中则需要获得intent 并且 将返回值放入intent中 public void onClick(View view) { Intent intent = getIntent(); intent.putExtra("bgMusic",bgmusic); intent.putExtra("sound",sound); intent.putExtra("planetype",planetype); setResult(StartGameActivity.RESULTCODE,intent); finish(); }
