Android Studio帶有單選按鈕值的列表視圖 - 如何檢查單選按鈕並獲取值？

現在的問題是我想單擊單選按鈕，並獲得textconfigurationid，並通過可變

請幫助我..

感謝

Answer 1

嘗試使用radioButton.isChecked （），它會告訴你單選按鈕是否被選中。此外，您還可以使用

radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 

     }

我解決我的問題與此代碼..

mconfiguration_id = configuration_id.getText().toString(); 
     shipping_title.setTag(mconfiguration_id); 
     shipping_title.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       if (position != mSelectedPosition && mSelectedRB != null) { 
        mSelectedRB.setChecked(false); 
       } 

       mSelectedPosition = position; 
       mSelectedRB = (RadioButton) v; 

       String mconfiguration_id; 
       mconfiguration_id = v.getTag().toString(); 
       Toast.makeText(context, mconfiguration_id, Toast.LENGTH_SHORT).show(); 
      } 

     }); 

     if(mSelectedPosition != position){ 
      shipping_title.setChecked(false); 
     }else{ 
      shipping_title.setChecked(true); 
      if(mSelectedRB != null && shipping_title != mSelectedRB){ 
       mSelectedRB = shipping_title; 
      } 
     }

我不能正確理解你的問題，但你想要得到單選按鈕和TextView的（textconfigurationid的價值是什麼我猜）存儲在一個變量中。

您可以在BaseAdapter的getView方法中處理您的點擊事件。 類似這樣的：

public View getView(final int position, View convertView, ViewGroup parent) { 
    //*** 
       Your code here.. 
           ***//  
    itemView.setBackgroundColor(color); 

    //You can get value of radio button and textview like this. 
    Boolean radioValue = shipping_title.isChecked(); 
    int configId = configuration_id.getText(); 

    return itemView; 
}
