从两个不同的活动向ListView传递EditText值

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="请输入值" />

// 获取EditText的值
EditText editText = findViewById(R.id.editText);
String value = editText.getText().toString();

// 创建Intent对象并传递值
Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("value", value);
startActivity(intent);

// 接收传递过来的值
Intent intent = getIntent();
String value = intent.getStringExtra("value");

// 将值添加到ListView中
List<String> list = new ArrayList<>();
list.add(value);

ListView listView = findViewById(R.id.listView);
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, list);
listView.setAdapter(adapter);
