我正在尝试在扩展 ListView 的 android 中创建自定义 ViewGroup。
ViewGroup 类如下所示。
public class SideBarView extends ListView implements View.OnClickListener, View.OnLongClickListener {
SideConnectionAdapter sideConnectionAdapter;
public SideBarView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
onCreateView();
}
public SideBarView(Context context, AttributeSet attrs) {
super(context, attrs);
onCreateView();
}
public SideBarView(Context context) {
super(context);
onCreateView();
}
private void onCreateView() {
inflate(getContext(), R.layout.side_bar, this);
}
public void setCursorForList(Cursor cursor) {
}
@Override
public void onClick(View v) {
}
@Override
public boolean onLongClick(View v) {
return false;
}
}
side_bar.xml 布局文件是
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:background="@drawable/side_background">
</ListView>
我在另一个活动布局 xml 文件中使用此自定义 ViewGroup,如下所示
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/scrollView">
<com.zis.view_group.SideBarView
android:id="@+id/side_bar"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="@drawable/side_background"/></RelativeLayout>
最后,我使用布局进行活动。对应的代码如下所示。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.activity_message_chatroom);
SideBarView sideBarView = (SideBarView) findViewById(R.id.side_bar);
sideBarView.setCursorForList(getCursor());
}
但是,使用这些代码,我得到了 android.view.InflateException: Binary XML file error。
