如何添加一个按钮控件在运行时的机器人XML看法？
问题描述：
我有一个Android XML布局，main.xml中。我想控件添加到这个布局在运行时（我想补充的一系列包含按钮控件的其他线性布局）。我能做到这一点，如果是的话，怎么办？
I have an android xml layout, main.xml. I would like to add controls to this layout at runtime (I would like to add a series of additional linear layouts that contain buttons controls). Can I do that and if yes, how?
感谢
答
我看到错误UR在这里做什么
I see the error u r doing here
LinearLayout mainLayout = (LinearLayout) findViewById(R.layout.main);
您ř取布局的LinearLayout对象，你应该采取的LinearLayout ID
You r taking the layout as Linearlayout object, you should take the LinearLayout id
试试这个
LinearLayout lnr = (LinearLayout) findViewById(R.id.LinearLayout01);
Button b1 = new Button(this);
b1.setText("Btn");
lnr.addView(b1);
