RadioButton 到 TextArea 问题

Question

我无法从无线电按钮中获取文本以显示为文本区域时显示。只能得到一个真值或假值。下面的代码是我遇到问题的地方。如果有任何建议，我将不胜感激。

 jTextArea2.setText(String.valueOf("Mixed Flavors:" + jRadioButton1.isSelected() + jRadioButton2.isSelected()
          + jRadioButton3.isSelected() + jRadioButton4.isSelected()));

Answer 1

我无法从单选按钮中获取文本以显示为文本区域，我只是希望您想尝试

之类的东西

if( jRadioButton1.isSelected() )
    jTextArea2.setText( String.valueOf("BLA") + jRadioButton1.getText() );
if( jRadioButton2.isSelected() )
    jTextArea2.setText( String.valueOf("BLA") + jRadioButton2.getText() );
if( jRadioButton3.isSelected() )
    jTextArea2.setText( String.valueOf("BLA") + jRadioButton3.getText() );
if( jRadioButton4.isSelected() )
    jTextArea2.setText( String.valueOf("BLA") + jRadioButton4.getText() );

Answer 2

获取文本您必须在单选按钮上使用 getText()。也没有必要使用 String.valueOf() 因为你试图在 TextArea 中设置的整个东西将变成一个字符串。

 jTextArea2.setText("Mixed Flavors:" + jRadioButton1.getText() + ":" + 
       jRadioButton1.isSelected() + " , "  + jRadioButton2.getText() + ":" +
       jRadioButton2.isSelected() + " , "+ jRadioButton3.getText() + ":"  + 
       jRadioButton3.isSelected() + " , " + jRadioButton4.getText() + ":" + 
       jRadioButton4.isSelected());
