如何以編程方式編輯創建的視圖

Question

所以在我的應用程序中，我有一個線性布局，以編程方式向其中添加了一些CardViews（android L cardview），如下所示：

    //This is my LinearLayout
    LinearLayout myLayout = (LinearLayout) findViewById(R.id.accounts_layout);

    //Here i create my CardView from a prepared xml layout and inflate it to the LinearLayout
    View card = View.inflate(getApplicationContext(), R.layout.account_card, myLayout);

    //Now i change the 'text' value of the Card's text views
    TextView cardTitle = (TextView) card.findViewById(R.id.text_card_title);
    cardTitle.setText("Title1");
    TextView cardDecription = (TextView) card.findViewById(R.id.text_card_description);
    cardDecription.setText("Description1");
    //...

    //Now i do the same thing for another card
    View card2 = View.inflate(getApplicationContext(), R.layout.account_card, myLayout);

    TextView cardTitle2 = (TextView) card2.findViewById(R.id.text_card_title);
    cardTitle2.setText("Title2");
    TextView cardDecription2 = (TextView) card2.findViewById(R.id.text_card_description);
    cardDecription2.setText("Description2");
    //...

正確顯示了兩張卡，但是發生的情況是，顯示的第一張卡在textViews中寫入了“ Title2”和“ Description2”，而第二張卡具有xml中定義的默認值。 在我看來，通過調用card.findViewById()或card2.findViewById()我總是得到第一張卡片的TextView。 所以我的問題是：我如何設法區分以編程方式創建的卡片，然后正確訪問其中的視圖？

嘗試這種方式，希望這將幫助您解決問題。

        LinearLayout myLayout = (LinearLayout) findViewById(R.id.accounts_layout);
        for (int i=1;i<=2;i++){

            View card = View.inflate(getApplicationContext(), R.layout.account_card, null);
            TextView cardTitle = (TextView) card.findViewById(R.id.text_card_title);
            cardTitle.setText("Title"+i);
            TextView cardDecription = (TextView) card.findViewById(R.id.text_card_description);
            cardDecription.setText("Description"+i);

            card.setTag(i);
            card.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    int pos = (Integer) v.getTag();
                    Toast.makeText(context,pos,Toast.LENGTH_SHORT).show();
                }
            });
            myLayout.addView(card);
        }
