我的TextView Layout Inflater有什么問題？

Question

我正在嘗試將TextView動態地添加到LinearLayout中，但是出現錯誤並且不知道如何解決：

這是被引用的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" />

我針對這個問題的代碼：

 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;
    }
}

Inflater仍然使我感到困惑，我仍然擁有類似的代碼來對表行進行膨脹，然后將它們添加到工作良好的表布局中：/有人可以幫我了解我在做什么錯嗎？

Answer 1

嘗試這樣的事情：

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

如果您在內部類或其他位置（onTouchListener）等無法訪問上下文的環境（即，不能使用關鍵字this），則也可以嘗試：

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

哦，嘗試將XML的TextView封裝成線性布局。

編輯：

嘗試這個：

<?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，可能是因為您的視圖沒有包裹在充氣機欄桿的布局中。

Answer 2

嘗試這個

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