Question

我想通过点击按钮将一个包传递给新活动。这是类适配器中bundle的代码，它扩展了recycleview adapter

private void passBundle (Vendor mItemSelected){
    mBundle = new Bundle();
    mBundle.putString("VENDOR_ID", mItemSelected.getVENDORID());
    mBundle.putString("CAT_ID", "" + mItemSelected.getVEN_TYPE());
    mBundle.putString("VENDOR_NAME", "" + mItemSelected.getVENDORNAME());
    mBundle.putString("CAT_ID", "" + mItemSelected.getVEN_TYPE());
    mBundle.putString("CAT_ID", "" + mItemSelected.getVEN_TYPE());
    mBundle.putString("VENDOR_AREA", "" + mItemSelected.getVENDORADDRESS());
    Intent in = new Intent(context,Chat_Activity.class);
    in.putExtra("Bundle", mBundle);
    Context.startActivity(in);
}

这是我在另一个活动中检索包数据的代码。

Bundle bundle = new Bundle();
    chatVenID = bundle.getString("VENDOR_ID", "");
    catID = bundle.getString("CAT_ID", "");
    vendorName = bundle.getString("VENDOR_NAME", "");
    vendorArea = bundle.getString("VENDOR_AREA","");

Answer 1

您可以调用

   Bundle bundle = getIntent().getBundleExtra("Bundle");
   chatVenID = bundle.getString("VENDOR_ID", "");

在onCreate（Bundle savedInstanceState）方法中; new Bunlde（）将创建一个新的bundle对象，无法从prev活动中获取pass值。

Answer 2

Bundle bundle = new Bundle();

在此代码中，您正在创建Bundle的新对象，因此您不会获得任何值。将其更改为

getIntent().getBundleExtra("Bundle")

将包从recycleview适配器传递给活动
