在我的MainActivity中,我有以下内容
Intent myintent=new Intent(MainActivity.this, DisplayInformation.class);
myintent.putExtra("displayName",userName.getText().toString());
myintent.putExtra("displayContact",userContact.getText().toString());
myintent.putExtra("displayAddress",userAddress.getText().toString());
myintent.putExtra("displayStore",userStore.getSelectedItem().toString());
myintent.putExtra("displayRequest",userRequest.getText().toString());
startActivity(myintent);
我可以在SecondActivity中正确显示它,这里是代码
TextView textView1 = (TextView)findViewById(R.id.textView1);
TextView textView2 = (TextView)findViewById(R.id.textView2);
TextView textView3 = (TextView)findViewById(R.id.textView3);
TextView textView4 = (TextView)findViewById(R.id.textView4);
TextView textView5 = (TextView)findViewById(R.id.textView5);
textView1.setText(getIntent().getStringExtra("displayName"));
textView2.setText(getIntent().getStringExtra("displayContact"));
textView3.setText(getIntent().getStringExtra("displayAddress"));
textView4.setText(getIntent().getStringExtra("displayStore"));
textView5.setText(getIntent().getStringExtra("displayRequest"));
Intent myintent=new Intent(DisplayInformation.this, Confirmation.class);
myintent.putExtra("confirmID",smsCode.getText().toString());
startActivity(myintent);
问题是当我在ThirdActivity中使用它时,它不起作用。
TextView textView2 = (TextView)findViewById(R.id.confirmName);
TextView textView3 = (TextView)findViewById(R.id.confirmContact);
TextView textView4 = (TextView)findViewById(R.id.confirmAddress);
TextView textView5 = (TextView)findViewById(R.id.confirmStore);
TextView textView6 = (TextView)findViewById(R.id.confirmRequest);
textView2.setText(getIntent().getStringExtra("displayName"));
textView3.setText(getIntent().getStringExtra("displayContact"));
textView4.setText(getIntent().getStringExtra("displayAddress"));
textView5.setText(getIntent().getStringExtra("displayStore"));
textView6.setText(getIntent().getStringExtra("displayRequest"));
没有任何错误或任何错误。只是它没有显示ThirdActivity中的值。不知道该怎么办?我想在ThirdActivity中显示相同的信息。

它没有显示任何内容,因为第二个Intent不包含您想要获得的值。实际上,你只放了" confirmID"第二个意图中的值。如果你还想要其他值,你甚至可以在第二个Intent中设置它们,就像你对第一个那样。

在将其发送到第三个活动之前,您必须将所有数据再次放入意图中。
Intent myintent = new Intent(DisplayInformation.this, Confirmation.class);
myintent.putExtra("confirmID", smsCode.getText().toString());
myintent.putExtra("displayName", textView1.getText().toString());
myintent.putExtra("displayContact", textView2.getText().toString());
myintent.putExtra("displayAddress", textView3.getText().toString());
myintent.putExtra("displayStore", textView4.getSelectedItem().toString());
myintent.putExtra("displayRequest", textView5.getText().toString());
startActivity(myintent);
