java - 我的 TextView Layout Inflater 有什么问题？

Question

我正在尝试将 TextView 动态添加到 LinearLayout，但出现错误并且不知道如何修复它：

这是被引用的 XML 布局文件：

<?xml version="1.0" encoding="utf-8"?>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

我解决这个问题的代码：

 public void simulateDebtLifeSpan(CreditCard card){
    LinearLayout ll = (LinearLayout)getLayoutInflater().inflate(R.layout.simulatedminimumpayments,null);
    if (card.balance>0){
       -line 215- TextView sim = (TextView)getLayoutInflater().inflate(R.layout.paymentrow,null);
        double newBalance =  card.getBalance()-card.getMinimumPayment(card.getBalance());
        sim.setText("Starting Balance: " + card.getBalance() + " Minimum Payment: " + card.getMinimumPayment(actBalance) + " New Balance: " + newBalance);
         ll.addView(sim);
         card.setBalance(newBalance);
         simulateDebtLifeSpan(card);
        return;
    }else {
        setContentView(R.layout.simulatedminimumpayments);
     return;
    }
}

充气机让我很困惑我仍然有类似的代码可以充气表格行，然后将它们添加到工作正常的表格布局中：/有人可以帮我理解我做错了什么吗？

Answer 1

尝试这样的事情：

LinearLayout layout1 = (LinearLayout) LayoutInflater.from(mCtx).inflate(R.layout.one_fifty_two_init, null);

如果您在一个内部类或其他位置（onTouchListener）等中。它无法访问上下文（即您不能使用关键字 this），您也可以尝试：

LinearLayout layout1 = (LinearLayout) LayoutInflater.from(MyActivity.this).inflate(R.layout.one_fifty_two_init, null);

哦，尝试将您的 TextView 包装在 XML 中的线性布局中。

编辑：

尝试这个：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/wrapper_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
<TextView
    ....your text view params
/>
</LinearLayout>

我唯一的想法是，这可能是因为您的视图没有包含在充气器 barfs 的布局中。

Answer 2

尝试这个

TextView sim = (TextView) View.inflate(this,R.layout.paymentrow,null);
