ListViewAdapterから配列にデータを渡す

Question

EditText ListからString Arrayにデータを渡したいとします。私は以下のように3つのクラスを作成しました： ListViewStudentNames。 ListViewStudentNamesAdapter。 MainClass。 以下のクラス：

ListViewStudentNames。

public class ListViewParentsNumber { 
private String StudentName ; 
private String StudentID ; 
private String ParentNumber ; 

public String getStudentName() { 
    return StudentName; 
} 

public void setStudentName(String studentName) { 
    StudentName = studentName; 
} 

public String getStudentID() { 
    return StudentID; 
} 

public void setStudentID(String studentID) { 
    StudentID = studentID; 
} 

public String getParentNumber() { 
    return ParentNumber; 
} 

public void setParentNumber(String parentNumber) { 
    ParentNumber = parentNumber; 
} 

public ListViewParentsNumber(String StudentName, String StudentID, String ParentNumber) 
{ 
    this.ParentNumber = ParentNumber ; 
    this.StudentID = StudentID ; 
    this.StudentName = StudentName ; 
} 


} 

ListViewStudentNamesAdapter

public class ListViewParentsNumberAdapter extends ArrayAdapter<ListViewParentsNumber> { 
private Context mContext; 
private ArrayList<ListViewParentsNumber> mData; 

public ListViewParentsNumberAdapter (Context mContext, ArrayList<ListViewParentsNumber> mData) { 
    super(mContext, R.layout.parents_shape, mData); 
    this.mContext = mContext; 
    this.mData = new ArrayList<ListViewParentsNumber>(); 
    this.mData.addAll(mData); 
} 
public int getCount() { 
    return mData.size(); 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) 
{ 
    if (convertView == null) { 
     LayoutInflater mInflater = (LayoutInflater) 
       mContext.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     convertView = mInflater.inflate(R.layout.parents_shape, null); 
    } 
    TextView Name = (TextView) convertView.findViewById(R.id.Student_name); 
    Name.setText(mData.get(position).getStudentName()); 

    EditText Parent_Number = (EditText) convertView.findViewById(R.id.Parent_Number); 
    Parent_Number.setText(mData.get(position).getParentNumber()); 

    return convertView; 
} 


} 

私のメインクラス は、あなたがあなたのEditTextとあなたのリストのafterTextChanged()更新中の値にTextWatcherを追加することができます

public class CHECKING_PARENTS_NUMBERS extends ActionBarActivity { 
private String USERNAME ; 
private String GRADE_ID ; 
private String CLASS_ID ; 
private Button Save ; 
private String USERID ; 
private Button Back ; 
private String PARENTS_PHONE_NUMBERS[]; 
private String STUDENT_ID_ARRAY[] ; 

private ListView mListView; 
private ListViewParentsNumberAdapter listViewStudentNameAdapter; 
private ArrayList<ListViewParentsNumber> listViewStudentNames; 



@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_checking__parents__numbers); 
    mListView = (ListView) findViewById(R.id.Student_names_List); 

    Save = (Button) findViewById(R.id.SaveEditing) ; 
    Back = (Button) findViewById(R.id.Back); 
    new GET_PARENTS_NUMBER(USERNAME,GRADE_ID,CLASS_ID).execute(); 
    Back.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      finish(); 

     } 
    }); 

    Save.setOnClickListener(new View.OnClickListener() 
    { 
     @Override 
     public void onClick(View v) 
     { 
      ListViewParentsNumber country; 
      for (int i = 0; i < listViewStudentNames.size(); i++) { 
       country = listViewStudentNames.get(i); 
       PARENTS_PHONE_NUMBERS[i] = country.getParentNumber() ; 
      }\\This Loop doesn't store the PARENTS_NUMBER IN the EditText in the array 
      new Update_Absence(USERNAME, GRADE_ID, CLASS_ID,PARENTS_PHONE_NUMBERS).execute(); 

     } 
    }); 
} 

Answer 1

です。

Parent_Number.addTextChangedListener(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) { 
       listViewStudentNames .add(position, Parent_Number.getText().toString().trim()); 
      } 
     });
