如何检查随机edittext是否已改变对Android的关注？

Question

我想知道用户是否改变了焦点并从一个editText转到了另一个。如果是这种情况，那么将通过ScrollView中的代码动态创建editTextes（和TextViews），因此在需要时会给出ID，editTextes可能是数百个。

我的想法是将这些ID存储在ArrayList上，然后执行循环并检查具有ArrayList中ID的editText是否改变了焦点。不幸的是，我的代码仅适用于已从activity_main.xml初始化的ArrayList中的第一项。为什么我的代码对ArrayList的其余ID无效？

部分代码如下：

MainActivity.java

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemSelectedListener {
    private GridLayout mlayout;

    //Creating ArrayList which holds all IDs of editTexts
    public static List<Integer> list = new ArrayList<>();

    Button additem;
    DynamicViews dnv;
    Context context;
    int f=1;
    int counter = 2;
    View view;
    EditText edit1;
    TextView test;
    int trent;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        mlayout = (GridLayout) findViewById(R.id.mylayout);
        additem = (Button) findViewById(R.id.addButton);
        edit1 = (EditText) findViewById(R.id.code1);
        test = (TextView) findViewById(R.id.textTest);

       //When ListArray's size is 0 I am inserting the first ID of EditText from .xml
       if (list.size()==0) {
            list.add(R.id.code1);
        }

       //Do a loop of ListArray according to the size, if focus of EditText changed then add EditText and TextView
        for (int v = 0; v<list.size(); v++){
             findViewById(list.get(v)).setOnFocusChangeListener(new View.OnFocusChangeListener() {
                @Override
                public void onFocusChange(View v, boolean hasFocus) {
                    if(!hasFocus){
                        addView(view);
                        counter+=2;
                    }

                }
            });
        }

    }
    public void addView (View view)
    {
        this.view=view;
        f=f+1;
        dnv = new DynamicViews(context);
        mlayout.addView(dnv.descriptopionTextView(getApplicationContext(),Integer.toString(f)),counter);
        mlayout.addView(dnv.receivedQuantityEditText(getApplicationContext(),f),counter+1);


    }

}

DynamicViews.java

//This is the class where I am creating dynamically TextView and EditText
public class DynamicViews {
    Context ctx;

    public DynamicViews(Context ctx) {
        this.ctx = ctx;
    }

    public TextView descriptopionTextView(Context context,String text) {

        final ViewGroup.LayoutParams lParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        final TextView textView = new TextView(context);
        textView.setLayoutParams(lParams);
        textView.setTextSize(16);
        textView.setTypeface(null, Typeface.BOLD);
        textView.setTextColor(Color.rgb(255,255,255));
        textView.setText(" "+ text+". ");

        return textView;

    }

    public EditText receivedQuantityEditText(Context context,int fin) {


        final ViewGroup.LayoutParams lParams = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        final EditText editText = new EditText(context);

         //I am adding the fin variable in ArrayList and then as ID. So the ID is now also inside the ArrayList
        MainActivity.list.add(fin);
        editText.setId(fin);
        editText.setTextSize(TypedValue.COMPLEX_UNIT_SP,16f);
        editText.setTextColor(Color.rgb(255,255,255));
        DrawableCompat.setTint(editText.getBackground(), ContextCompat.getColor(context, R.color.colorPrimary));
        editText.setInputType(TYPE_CLASS_NUMBER);
        return editText;

    }
