Question

如何以编程方式添加EditText ?

我是这么写的:

View RV = inflater.inflate(R.layout.fragment__dummy,container, false);
LinearLayout LL = new LinearLayout(getActivity());
EditText ET = new EditText(getActivity());
ET.setId(5);
ET.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
LL.addView(ET);
return RV;

谢谢!

Answer 1

LinearLayout layout=(LinearLayout)view.findViewById(R.id.linearLayout);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                        android.widget.LinearLayout.LayoutParams.MATCH_PARENT,
                        android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);
                EditText edttext= new EditText(this);
                edttext.setId("edittext");
                edttext.setLayoutParams(params);
            layout.addView(edttext);

Answer 2

您也在动态创建LinearLayout LL。

您需要将其添加到RV中，如

((ViewGroup)RV).addView(LL);

你也应该为LL设置LayoutParams
