Question

In my project I have such situation, that one activity should transfer the value to another. And depending of this value should be chosen needable menu element. I tried to do it with the help of bundle, but I don't know how to choose the needable element of menu. Can I access to menu item with the help of this number or I can access only with the help of the id?

尝试这个

• 如果您正在使用活动，您可以使用这样的意图在点击时传递数据

  create_new_bank.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          Intent intent = new Intent(BankDetailsActivity.this, AddBankDetailsActivity.class);
          intent.putExtra("id",id);
          intent.putExtra("bank_Name", bankname);
          intent.putExtra("holder_name", holdername);
          intent.putExtra("acc_no", accountno);
          startActivity(intent);
  

• 并获取下一个活动的数据，例如（AddBankDetailsActivity.this），如下所示：

  /* using get string intent method  get intent value*/
  private void getStringIntent() {
  Intent intent = getIntent();
  String bank_id = intent.getStringExtra("id");
  String accountName = intent.getStringExtra("holder_name");
  String accountNo = intent.getStringExtra("acc_no");
  String bankName= intent.getStringExtra("bank_Name");
  

注意： 确保您的 putExtra 键值与 getStringExtra 键值相同
