Question

我有一个扩展LinearLayout的自定义布局类。当我点击+按钮时，它会在该按钮下方添加另一个布局，如图所示。所以我有一个父布局，其中包含另一个布局（每个布局都有自己的颜色）。但是当我想要更改某些文本并将其键入EditText（布局1）时，它总是在最后一个布局中设置Text。

我知道它正在发生，因为当我创建我的布局的另一个实例时，它会覆盖＆＃34; textView的名称。我试过getChildAt（）;但它的View类型，没有setText方法。任何帮助深表感谢。谢谢！：）

    for(int i = 0; i<= getChildCount()-1;i++){

    }

    Toast.makeText(getContext(), ""+(this.getChildCount()), Toast.LENGTH_SHORT).show();

    pocetPracovniku++;

}

}

如何根据ID设置文本？
