Question

重新发布这个，因为我最初用错误的标题发布它，所以它在没有问题的情况下迷失了。

我正在创建一个小型时间表应用，目前正在创建一个带有一些标签的屏幕。每个选项卡都是一个单独的片段，每个选项卡中都有20个编辑文本。我的目标是，如果用户键入其中一个编辑文本，然后单击它并且焦点丢失，则将文本从编辑文本字段发送到主活动。然后，单击确认按钮时，编辑文本中的任何文本都将保存到SQLite数据库中。我的问题是焦点听众似乎没有工作。这是片段代码之一：

package com.example.schoolandrevisiontimetable;

     public void MondayEditTextChanged(String mondayEditText, int period, int position){
         mondayString = mondayEditText;
         mondayPeriod = period;

         monCallback.onMondayEditTextChanged(mondayString, mondayPeriod, mondayPosition);
     }


    public interface OnMondayEditTextChangedListener {

    EditText[][] mondayInput   = new EditText[11][2];
    String  [][] mondayStrings = new String  [11][2];




    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View rootView = inflater.inflate(R.layout.fragment_input_slessontime_monday,
                container, false);

        mondayInput[1][0] = (EditText) rootView.findViewById(R.id.mondayslesson1start);

        mondayInput[2][1]   = (EditText) rootView.findViewById(R.id.mondayslesson2end);

...

//this continues up to 10. Had to delete the rest due to character limitations

        Log.v("Monday", "Edit texts all set");



        return rootView;    
    }

     @Override

                        + " must implement OnMondayEditTextChanged");
            }
        }

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        Log.v("monday", "focus change!");
        String edittext;
    if(!hasFocus)   
        switch(v.getId()){

        case R.id.mondayslesson1start:
            edittext = mondayInput[1][0].getText().toString();
            MondayEditTextChanged(edittext,1,0);

以及活动的XML：

    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

</LinearLayout>

</LinearLayout>
