Java Android：如何启用/禁用复选框，具体取决于首先选择的单选按钮

Android: How do I enable/disable a Checkbox, depending on a Radio button being selected first

提问by silver_c

Basically I have a Radio Group with two radio buttons, one of them is labelled RUN and the other is labelled PASS. Just underneath this I also have a check-box labelled "Pass Complete"

基本上我有一个带有两个单选按钮的无线电组，其中一个标记为 RUN，另一个标记为 PASS。就在这下面，我还有一个标记为“通过完成”的复选框

Question: How do I disable the check-box when RUN radio button is selected (so the checkbox can't be selected) and enable it while the PASS radio button is selected? Any help constructing some type of IF statement would be much appreciated.

问题：如何在选择 RUN 单选按钮时禁用复选框（因此无法选择该复选框）并在选择 PASS 单选按钮时启用它？任何构建某种类型的 IF 语句的帮助将不胜感激。

Use Radiogroup.setOnCheckedChangeListener, then on checked change use checkbox.setenable

使用 Radiogroup.setOnCheckedChangeListener，然后在检查更改时使用 checkbox.setenable

You probably will want to add a listener to your checkbox, that will check for the selection and update the other views as needed.

您可能希望在复选框中添加一个侦听器，它将检查选择并根据需要更新其他视图。

 captureGrp = (RadioGroup) findViewById(R.id.runandpass);
 myRadio1 = (RadioButton) findViewById(R.drawable.radio1);
 myRadio2 = (RadioButton) findViewById(R.drawable.radio2);
 myRadio3 = (RadioButton) findViewById(R.drawable.radio3);

 captureGrp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {

     public void onCheckedChanged(RadioGroup group, int checkedId) {


            if (checkedId == R.id.radio1) {
                //disable and enable as needed
            } else if (checkedId == R.id.radio2) {
                // disable as needed
            } else {
                // add as many as you need
            }
        }
