Activity.java 中的實現

LinearLayout  thisNoLayout = findViewById(R.id.ly_this_no);
//因為父控制元件中寫的是五個TextView,所有這裡的getChildCount也是五個
String resultArray=new  String[]{"a","b","c","d","e"};
 for (int i = 0; i < thisNoLayout.getChildCount(); i++) {
                    TextView textView = (TextView) thisNoLayout.getChildAt(i);
                    String value = resultArray[i];
                    textView.setText(value);
                }
 

通過上訴方式,就可以完成對LinearLayout   裡面所有沒有標明id的TextView進行賦值了
