如何從片段中的不同視圖收集值？

Question

我想從Fragment中的所有視圖中選擇的單選按鈕收集數據並將其發佈到服務器，我如何收集數據？至少有人能幫我敬酒嗎？

注：此刻我已經在做一個屏幕，但我想所有屏幕的集體數據。

Button myButton = (Button) layoutView.findViewById(R.id.findSelected); 
      myButton.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 

        StringBuffer responseText = new StringBuffer(); 
        responseText.append(""); 

        // Get selected radiobuttons 
        if (radioGroup1.getCheckedRadioButtonId() != -1) { 
         text1 = btn.getText().toString(); 
         Log.d("Button", "Text 1 : " + text1); 
        } 

        if (radioGroup2.getCheckedRadioButtonId() != -1) { 
         text2 = btn2.getText().toString(); 
         Log.d("Button", "Text 2 : " + text2); 
        } 


        Toast.makeText(
          thiscontext, 
          "Data Posting : APPLICATION : " 
            + text1 + " \nDEVICE : " + text2, 
          Toast.LENGTH_LONG).show(); 


       } 
      });

添加一個公共方法在每一個片段，像

public HashMap<String, Boolean> getRadiosStatus{ 
    //TODO put every radio button's status to hashmap and return it. 
} 

然後，調用此方法在活動。您可以通過調用所有相同的方法從所有片段中獲取所有狀態。
