Question

我有一个Activity，其中一个RadioGroup包含2个RadioButtons（rdbtn4，rdbtn5）。

然后我有一个XML文件，其中包含LinearLayouts：

linlay4只包含4个Spinners，
linlay5另外五个Spinners。

然后用户可以根据自己的喜好设置Spinners，按下按钮后2 TextViews设置了特定的文本（取决于所选的Spinner值）。

这与linlay4完美配合，选择了linlay5未设置TextView。

这是我的代码：

你的变量名称非常神秘，但我想我看到了什么错。尝试更改btnCalcWid中的检查，如下所示：

btnCalcwid.setOnClickListener(new View.OnClickListener() 
{
    public void onClick(View v) 
    {
        if (rdbtn4rings.isChecked())
        {
            String s41 = String.valueOf(sp4Farbe1.getSelectedItemId()); //Farbe 1
            String s42 = String.valueOf(sp4Farbe2.getSelectedItemId()); //Farbe 2
            String s43 = String.valueOf(sp4Farbe3.getSelectedItemId()); //Multiplikator
            String s44 = String.valueOf(sp4Farbe4.getSelectedItemId()); //Toleranz
            int ds43 = Integer.parseInt(s43);
            int ds44 = Integer.parseInt(s44);
            rise1(ds43); 
            String snewTolerance = String.valueOf(getToleranceValue(ds44));

            //Output:

            tvWidResultValue.setText("" + s41 + s42 + "*10^" + ds43 + " Ohm");
            tvWidToleranzValue.setText(""+ snewTolerance + " %");
        }
        else if (rdbtn5rings.isChecked())
        {
            String s51 = String.valueOf(sp5Farbe1.getSelectedItemId()); //Farbe 1
            String s52 = String.valueOf(sp5Farbe2.getSelectedItemId()); //Farbe 2
            String s53 = String.valueOf(sp5Farbe3.getSelectedItemId()); //Farbe 3
            String s54 = String.valueOf(sp5Farbe4.getSelectedItemId()); //Multiplikator
            String s55 = String.valueOf(sp5Farbe5.getSelectedItemId()); //Toleranz
            int ds54 = Integer.parseInt(s54);
            int ds55 = Integer.parseInt(s55);
            rise1(ds54);
            String snewTolerance = String.valueOf(getToleranceValue(ds55));

            //Output:

            tvWidResultValue.setText("" + s51 + s52 + s53 + "*10^" + ds54 + " Ohm");
            tvWidToleranzValue.setText(""+ snewTolerance + " %");
        }//else if
    }//onClick
});//setOnClickListener

两个布局，一个禁用
