Activity  A  与Activity B 之间如何进行数据传递

Activity  A

Bundlebundle =new Bundle();

bundle.putString("voiceString", voiceString.toString());

Intent intent =new Intent();

intent.putExtras(bundle);

intent.setClass(this, BActivity.class);

startActivity(intent);

Activity B

String voiceString = getIntent().getExtras().getString("voiceString");

Log.e("我是Activity  A 传过来的值："+voiceString);
