Android
Fragmentの中にあるEditTextの値を親であるActivityに渡す場合、ちょっと面倒な仕込みが必要になります。
ReviewActivityというActivityの中に、ReviewReceiverFragmentが複数含まれます。
ReviewReceiverFragmentに、点数をカウントするチェックボックスとコメントを記載する欄があります。
まずはFragmentです。
//ReviewReceiverFragment.java
public class ReviewReceiverFragment extends Fragment {
private ArrayList<Sender> senderArrayList;
public CheckBox unloading_wait_time;
private OnGetFromUserClickListener mListener;
private int receiver_id;
private CheckBox unloading_place_info;
private EditText comment_edit_text;
private final static String TAG = "ReviewReceiverFragment";
public ReviewReceiverFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.review_receiver_fragment, container, false);
//中略
unloading_wait_time = (CheckBox) v.findViewById(R.id.unloading_wait_time);
unloading_place_info = (CheckBox) v.findViewById(R.id.unloading_place_info);
comment_edit_text = (EditText) v.findViewById(R.id.comment);
unloading_wait_time.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (v.getId() == R.id.unloading_wait_time) {
sendRatingToActivity(v);
}
}
});
unloading_place_info.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (v.getId() == R.id.unloading_place_info) {
sendRatingToActivity(v);
}
}
});
comment_edit_text.addTextChangedListener(mTextWatcher);
return v;
}
private TextWatcher mTextWatcher = new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
// String comment = comment_edit_text.getText().toString();
Log.d(TAG, "afterTextChanged" + s.toString());
sendCommentToActivity();
// sendCommentToActivity();
}
};
/**
* 点数を返す
* チェックが付いたものを減点
*
* @return
*/
public String getComment() {
String comment = comment_edit_text.getText().toString();
return comment;
}
/**
* 点数やコメントを数えるために追加
*/
@Override
public void onAttach(Context context) {
super.onAttach(context);
try {
mListener = (OnGetFromUserClickListener) context;
} catch (ClassCastException e) {
throw new ClassCastException(context.toString() + " must implement OnGetFromUserClickListener");
}
}
public void sendRatingToActivity(View v) {
if (mListener != null) {
int rate = getRate();
mListener.getRateFromFragment(rate, receiver_id, false);
}
}
public void sendCommentToActivity() {
if (mListener != null) {
String comment = getComment();
mListener.getCommentFromFragment(comment, receiver_id);
}
}
}
ポイント①はリスナーを作って、チェックボックスを押したり、コメント欄を編集した場合に、それを呼び出すことです。
ポイント②はaddTextChangedListener でTextWatcherを利用することです。
これがないと、クリックだけだと、テキストボックスを編集した後、すぐにActivityで送信ボタンを押されたりする場合、編集した後のテキストが取得できません。
//OnGetFromUserClickListener.java
public interface OnGetFromUserClickListener {
void getRateFromFragment(int rate, int receiver_id, boolean is_sender);
void getCommentFromFragment(String comment, int receiver_id);
}

Log.d(TAG, "会社ID：" + mCompanyId);

Delivery delivery = deliveryList.get(count);
Bundle bundle = new Bundle();
bundle.putParcelable("delivery", delivery);
bundle.putInt("delivery_number", count);
review_fragment.setArguments(bundle);
fragTransaction.add(R.id.each_delivery, review_fragment, "review" + count);
//レビューの初期化
ArrayList<Receiver> receiverArrayList = delivery.getReceiverList();
for (int count_receiver = 0; count_receiver < receiverArrayList.size(); count_receiver++) {
Receiver receiver = receiverArrayList.get(count_receiver);
ArrayList<Sender> senderList = delivery.getSenderList();
//発荷主は一つと仮定
Sender sender = senderList.get(0);
mSender_id = sender.getCompany_id();

// reviewArrayList.add(receiver.getCompany_id());
