Question

这里的xml就像这样

<com.example.MyViewGroup 
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/screen" 
android:orientation="vertical"
android:layout_width="fill_parent" 
android:layout_height="fill_parent">
</com.example.MyViewGroup>

课程MyViewGroup扩展ViewGroup。所以我的问题是可以以编程方式创建按钮并将其添加到视图中吗？

Answer 1

    @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

            Context context = new ContextThemeWrapper(getActivity(), R.style.Beam_Light);
            LayoutInflater localInflater = inflater.cloneInContext(context);
            final View root = localInflater.inflate(R.layout.sv_contact_info_fragment, container, false);
            LinearLayout dynamicLayout = (LinearLayout) root.findViewById(R.id.beam_contact_info_fragment_lchild);
            View view = localInflater.inflate(R.layout.sv_header, null); 
            dynamicLayout.addView(view);
    }

Answer 2

是的，这是可能的。您可以使用addView()方法

以下是一个简单的例子：

MyViewGroup mvg = (MyViewGroup) findViewById(R.id.screen);
Button btn = new Button(context);
btn.setText("My Button");
mvg.addView(btn);

如何在Android中动态创建按钮？
