我需要在lib中创建自定义视图。我的代码： 自定义lib中的自定义视图（在具有一个类（是视图）的项目中）：
public class PagingHTMLView extends SurfaceView {
public PagingHTMLView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public PagingHTMLView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public PagingHTMLView(Context context) {
super(context);
}
}
我创建测试项目并右键单击以测试项目=＆gt;构建路径=＆gt;配置构建路径=＆gt;选择项目选项卡并选择lib项目。 我在测试项目中创建了一个活动：
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PagingHTMLView p=new PagingHTMLView(this);
p.setLayoutParams(new LayoutParams(-1, -1));
RelativeLayout l=(RelativeLayout) findViewById(R.id.layout);
l.addView(p);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
布局：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/com.inazaruk.app"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:id="@+id/layout">
</RelativeLayout>
并收到错误：

如果在测试项目中我使用代码创建活动：
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
