基于radioGroup选择的Android EditText可见性

Question

如果选择了 radioButton1，我需要隐藏 editText1 并显示 editText2 并且如果选择了 radioButton2，我需要隐藏 editText2 并显示 editText1。两个按钮都在一个 radioGroup 中。我不确定是否有 radioGroup onChange 事件返回选中了哪个 radioButton？如果是这样，那我可以做

EditText et1 = (EditText) findViewById(R.id.editText1);
et1.setVisibility(View.INVISIBLE);

您可以将 OnCheckedChangeListener() 设置为您的 radioGroup:

      final EditText et1 = (EditText) findViewById(R.id.editText1);
      final EditText et2 = (EditText) findViewById(R.id.editText2);

      RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
      radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(RadioGroup group, int checkedId) {
                    if(checkedId == R.id.radioBtn1){
                       et1.setVisibility(View.VISIBLE);
                       et2.setVisibility(View.INVISIBLE);  
                    } else {
                       et1.setVisibility(View.INVISIBLE);
                       et2.setVisibility(View.VISIBLE);  
                    }
                }
       });
