当我点击我的按钮时，我在父布局中插入了一个布局。这是我单独创建的子布局。

问题是我不知道如何在我插入的子布局中获得任何值。请注意，我将多次插入此布局。

TextView addNew, principal;
LinearLayout linearlayout;
Spinner spnPrincipal;
View inflatedLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_order_form);

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    spnPrincipal = (Spinner) findViewById(R.id.principal);
    linearlayout = (LinearLayout) findViewById(R.id.linearLayout);

    principal = (TextView) findViewById(R.id.principaltxt);
    addNew = (TextView) findViewById(R.id.addNew);
    addNew.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            LayoutInflater inflater = LayoutInflater.from(OrderForm.this);
            inflatedLayout = inflater.inflate(R.layout.add_new_item, null, false);
            linearlayout.addView(inflatedLayout);
        }
    });

}

您可以使用

 ...inflatedLayout.findViewById(...)

获取特定布局的特定元素的值。

因此，对于多个布局，您可以使用多个查看对象，或者每次使用其他布局初始化视图对象之前，您都可以存储元素的值。

如何在我多次插入的布局中获取对象（EditText，TextView，Spinner）的值？
