我已经在这个项目上工作了一段时间，我无法将所有数据显示在活动的下一页上。我在一个页面上有12个微调器，并且我需要所有这些数据才能在下一个“活动”页面上以12个不同的textview显示。我有它，以便它使用按钮在页面之间移动。数据确实显示。仅当它是最后选择的项目并且我需要显示所有12个数据点时。如果不显示数据，则为空。这是我正在使用的一些代码。请帮忙。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_page5);
/* Bundle extra = getIntent().getExtras();
String Sent;
Sent = extra.getString("Sent");
tv.setText("Sensor Type: "+ Sent);*/
tv = (TextView)findViewById(R.id.textViewCustName);
tv1 = (TextView)findViewById(R.id.textViewCustomer_id);
tv2 = (TextView)findViewById(R.id.textViewProloID);
tv3 = (TextView)findViewById(R.id.textViewProloname);
tv4 = (TextView)findViewById(R.id.textViewSent);
tv5 = (TextView)findViewById(R.id.textViewSenid);
tv6 = (TextView)findViewById(R.id.textViewVename);
tv7 = (TextView)findViewById(R.id.textViewVenid);
tv8 = (TextView)findViewById(R.id.textView2);
tv9 = (TextView)findViewById(R.id.textView3);
tv10 = (TextView)findViewById(R.id.textView4);
Intent intent = getIntent();
value = intent.getStringExtra("Sensor Type");
tv.setText("Sensor Type:" + value);
Intent two = getIntent();
message = two.getStringExtra("Sensor ID");
tv1.setText("Sensor ID:" + message);
Intent three = getIntent();
voice = three.getStringExtra("Vendor Name");
tv2.setText("Vendor Name:" + voice);
Intent four = getIntent();
chorus = four.getStringExtra("Vendor ID");
tv3.setText("Vendor ID:" + chorus);
这是从第一个活动开始的。请注意，我已经初始化了所有内容，而这正是我输入数据的地方
