Linearlayoutは子を取り除くことができません

Question

一つLinearlayoutRadioGroupとtextViewを作成して動的に追加しています。次回にメソッドを呼び出すと、Textviewが削除されていますが、古いラジオボタンは削除されません。ここで

はコードです：ここでは

public void setShippingMethods() { 
    shippingChargesLayout.removeAllViews(); 
    final RadioGroup radioGroup = new RadioGroup(getActivity()); 

    radioGroup.setOrientation(LinearLayout.VERTICAL); 
    TextView textView = new TextView(getActivity()); 
    textView.setText("Select Shipping Options:"); 
    shippingChargesLayout.addView(textView); 
    for (int i = 0; i < shippingDetailsList.size(); i++) { 
     RadioButton radioButton = new RadioButton(getActivity()); 
     radioButton.setText("" + shippingDetailsList.get(i).getMethodTitle() + "-" + (new SessionManager(getActivity()).getCurrency()) + df.format(shippingDetailsList.get(i).getAmount())); 

     RadioGroup.LayoutParams params = new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT); 
     radioGroup.addView(radioButton, params); 
     radioButton.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT)); 
    } 
    shippingChargesLayout.addView(radioGroup); 

    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(RadioGroup radioGroup, int i) { 
      shipmentCode = shippingDetailsList.get(i - 1).getCarrierCode(); 
      Log.v("carrierCode", "" + shipmentCode); 
     } 
    }); 

    checkout.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      if (radioGroup.getCheckedRadioButtonId() == -1) { 
       Toast.makeText(getActivity(),"Select shipping options.",Toast.LENGTH_LONG).show(); 
      } else { 
       completeOrder(); 
      } 
     } 
    }); 
} 

イメージは以下のとおりです。

私はあなたのコード内のいくつかの変更を行いました。

public void setShippingMethods() { 
    shippingChargesLayout.removeAllViews(); 
    final RadioGroup radioGroup = new RadioGroup(getActivity()); 
    RadioGroup.LayoutParams params = new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT); 
    radioGroup.setLayoutParams(params); 
    radioGroup.setOrientation(LinearLayout.VERTICAL); 
    TextView textView = new TextView(getActivity()); 
    textView.setText("Select Shipping Options:"); 
    shippingChargesLayout.addView(textView); 
    for (int i = 0; i < shippingDetailsList.size(); i++) { 
     RadioButton radioButton = new RadioButton(getActivity()); 
     radioButton.setText("" + shippingDetailsList.get(i).getMethodTitle() + "-" + (new SessionManager(getActivity()).getCurrency()) + df.format(shippingDetailsList.get(i).getAmount())); 
     radioGroup.addView(radioButton); 
    } 
    shippingChargesLayout.addView(radioGroup); 

    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     @Override 
     public void onCheckedChanged(RadioGroup radioGroup, int i) { 
      shipmentCode = shippingDetailsList.get(i - 1).getCarrierCode(); 
      Log.v("carrierCode", "" + shipmentCode); 
     } 
    }); 

    checkout.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      if (radioGroup.getCheckedRadioButtonId() == -1) { 
       Toast.makeText(getActivity(),"Select shipping options.",Toast.LENGTH_LONG).show(); 
      } else { 
       completeOrder(); 
      } 
     } 
    }); 
}
