我正在使用Android开发网站中的抽屉导航,但它没有在列表视图中显示标题或标题或图像,所以你能告诉我如何在android开发中的抽屉导航中添加标题和图像网站没有? Like this example
以下是一些代码:<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
The drawer is given a fixed width in dp and extends the full height of
the container. A solid background is used for contrast
with the content view. -->
<ListView
android:layout_weight="1"
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="fill_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="1dp"
android:background="@color/Black"/>
</android.support.v4.widget.DrawerLayout>

这是解决方案:
在项目中创建一个新的xml文件。并在xml viewer中粘贴下面的代码。之后在图形视图中,您可以看到自定义列表视图。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="@drawable/list_selector">
<ImageView
android:id="@+id/icon"
android:layout_width="25dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="12dp"
android:layout_marginRight="12dp"
android:contentDescription="@string/desc_list_item_icon"
android:src="@drawable/ic_home"
android:layout_centerVertical="true" />
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="@id/icon"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:textColor="@color/list_item_title"
android:gravity="center_vertical"
android:paddingRight="40dp"/>
<TextView android:id="@+id/counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/counter_bg"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="8dp"
android:textColor="@color/counter_text_color"/>
并转到列表视图适配器[因为在您的导航栏中使用列表视图来显示菜单项。]在gat视图方法中更改新创建的布局的布局[我们现在创建的列表项]
这是我的获取视图方法。它可能与您的getview方法不同。但我想这会对您有帮助。
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.drawer_list_item_old, null);
}
ImageView imgIcon = (ImageView) convertView.findViewById(R.id.icon);
TextView txtTitle = (TextView) convertView.findViewById(R.id.title);
TextView txtCount = (TextView) convertView.findViewById(R.id.counter);
imgIcon.setImageResource(navDrawerItems.get(position).getIcon());
txtTitle.setText(navDrawerItems.get(position).getTitle());
// displaying count
// check whether it set visible or not
if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}

您必须使用自定义布局创建自定义Adapter类,并将该适配器设置为列表视图。检查问题并回答here
