Question

我在一个活动中有11个ToggleButtons，目前，在onCreate中，我声明了一个11个ToggleButtons的数组，我在onCreate（）中定义，就像那样：

private static ToggleButton toggleButton[] = new ToggleButton[11];

...

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

    toggleButton[0] = (ToggleButton) findViewById(R.id.ToggleButton00);
    toggleButton[1] = (ToggleButton) findViewById(R.id.ToggleButton01);
    toggleButton[2] = (ToggleButton) findViewById(R.id.ToggleButton02);
    toggleButton[3] = (ToggleButton) findViewById(R.id.ToggleButton03);
    toggleButton[4] = (ToggleButton) findViewById(R.id.ToggleButton04);
    toggleButton[5] = (ToggleButton) findViewById(R.id.ToggleButton05);
    toggleButton[6] = (ToggleButton) findViewById(R.id.ToggleButton06);
    toggleButton[7] = (ToggleButton) findViewById(R.id.ToggleButton07);
    toggleButton[8] = (ToggleButton) findViewById(R.id.ToggleButton08);
    toggleButton[9] = (ToggleButton) findViewById(R.id.ToggleButton09);
    toggleButton[10] = (ToggleButton) findViewById(R.id.ToggleButton10);

我确信应该有更好的方法（比如循环），任何想法？你会怎么做？

试试这段代码：

ToggleButton toggleButton[] = new ToggleButton[11];
    int arrayindex = 0;
    int viewcount = 0;
    while (arrayindex < 11) {

        View v = asyncLayout.getChildAt(viewcount);
        if (v instanceof ToggleButton) {

            toggleButton[arrayindex] = (ToggleButton) v;
            arrayindex ++;
        }
        viewcount ++ ;

    }
