在 Main. xml 中检索按钮组
原标题:Retrieve Group of Buttons in Main.xml

我在 main.xml 中创建了9个 butto 视图,并将其命名为 button1, button2...... button9.. 然后在我的代码中我创造了一个 ArrayList 按钮,而且很明显,这个按钮阵列会将我的按钮保存在 main.xml 中,而且据我所知,要获得我主机中的按钮,我需要使用查找ViViewById的方法,基本上我需要绕过阵列才能获得按钮。xml

ArrayList<Button> buttons;
int MAXBTN = 9;
for( int i = 0; i < BTN; i++ )
{
    // Code here to use the findViewById method to get the button
}

我的问题是我需要通过 R.id. button1. R.id. button3 到查找 ViewById 方法, 但我需要翻转这个方法。 无论如何, 在循环时, 我可以通过 finddViewById 的柜台吗?

请出谋划策

最佳回答

你可以试试这个

ArrayList<Button> buttons;
int MAXBTN = 9;
for( int i = 0; i < BTN; i++ )
{
    String buttonID = "Button" + i+1 ;
    int resID = getResources().getIdentifier(buttonID, "id", "packageName");
    buttons.get(i) = ((Button) findViewById(resID));
}
