xml布局和动态布局结合使用

1. 新建工程

2. 新建布局 userview.xml， 布局中上面部分是一个textview， 下部分是一个button

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
</LinearLayout>
3. 新建View--MyView, 首先加载了userview布局，然后横向部分新增加了一个button按钮

public class MyView extends LinearLayout {
private View userview;
private Button anotherButton;
public MyView(Context context, AttributeSet attrs) {
super(context);
// TODO Auto-generated constructor stub
setOrientation(LinearLayout.HORIZONTAL);

userview = inflate(context, R.layout.userview, null);//这里的第三个参数应该为null

anotherButton = new Button(context);
anotherButton.setText("another");

addView(userview);
addView(anotherButton);

}
}
4. MainActivity

public class MainActivity extends Activity {
private MyView myView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myView = new MyView(this, null);
setContentView(myView);

}
}
