Android 我的意向活动

我想发送两个文本视图。我正在发送意图，但没有得到期望的结果。我得到两个$12.99作为我的输出。为什么它没有显示比萨饼的名字？请帮忙。我想在我的应用程序上一行输入我的比萨饼名称和价格。这是我的密码： XML

我的目的是：

Intent intent1 = new Intent(SplPizzas.this, Cart.class);
String message1 = TextView1.getText().toString(); 
intent1.putExtra(Message1, message1);
String message2 = TextView2.getText().toString();
intent1.putExtra(Message2, message2);
startActivity(intent1);
break;

活动2

Intent intent = getIntent();
String message1 = intent.getStringExtra(SplPizzas.Message1);
String message2 = intent.getStringExtra(SplPizzas.Message2);
TextView output1 = (TextView) findViewById(R.id.textview1);
output1.setText(message1);
TextView output2 = (TextView) findViewById(R.id.textview2);
output2.setText(message2);

@法拉利的代码编写方式有点糟糕：p

我把它格式化了一点，然后在我这端运行

据我所知，我认为您错误地为SplPizzas.Message1和SplPizzas.Message2分配了相同的“字符串”。
这就是为什么在这两种情况下，您得到的价值相同，即12.99美元。
请核实

以下是代码：

MainActivity.java-->从代码中选择SplPizzas.java

Main2Activity.java-->Cart.java从代码中删除

activity_main.xml-->代码的第一个屏幕

activity_main2.xml-->代码的第二个屏幕

您的代码格式应该比这更好，其次，您不能按意图发送

文本视图。
