Android 基于 radioGroup 选择的 EditText 可见性

Question

如果选择 radioButton1，我需要隐藏 editText1 并显示 editText2，并且如果选择 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 returns 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);

Answer 1

您需要在 radioGroup 上添加 OnCheckedChangeListener:

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {         
        // checkedId is the RadioButton selected
        if (checkedId == R.id.radioButton1) {
            editText1.setVisibility(View.INVISIBLE);
            editText2.setVisibility(View.VISIBLE);
        } else if (checkedId == R.id.radioButton1) {
            editText1.setVisibility(View.VISIBLE);
            editText2.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);  
                    }
                }
       });

您可以实现 Rami 和 sv3k 所回答的功能。

还有一个选项，你可以尝试实现你想要的。那是在每个单选按钮上设置 onClickListener。

像这样。

   RadioGroup  radioGroup=(RadioGroup)findViewById(R.id.radioGroup);
        RadioButton radio1= (RadioButton)radioGroup.findViewById(R.id.radio1);
        RadioButton radio2= (RadioButton)radioGroup.findViewById(R.id.radio2);
        radio1.setOnClickListener(new View.OnClickListener() 
         {
             @Override
             public void onClick(View v) {
                 // TODO Auto-generated method stub
                 et1.setVisibility(View.INVISIBLE);
                 et2.setVisibility(View.VISIBLE);
             }
         });

        radio2.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                et2.setVisibility(View.INVISIBLE);
                et1.setVisibility(View.VISIBLE);
            }
        });
