Activity.java 中的实现
LinearLayout thisNoLayout = findViewById(R.id.ly_this_no);
//因为父控件中写的是五个TextView,所有这里的getChildCount也是五个
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);
}
通过上诉方式,就可以完成对LinearLayout 里面所有没有标明id的TextView进行赋值了
