我的抽屉布局:
<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"
>
<!-- The main content view -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<!-- The navigation drawer -->
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="start"
android:divider="@android:color/darker_gray"
android:dividerHeight="0.1dp"
android:listSelector="@drawable/drawer_list_selector"
/>
</android.support.v4.widget.DrawerLayout>
我的列表行:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="@+id/drawer_list_item_image"
android:contentDescription="Menu item image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="5dp"
android:layout_marginRight="20dp"
android:layout_gravity="center_vertical"
/>
<TextView
android:id="@+id/drawer_list_item"
android:layout_width="match_parent"
android:layout_height="48dp"
android:gravity="center_vertical"
android:textColor="@android:color/black"
/>
</LinearLayout>
然后是我的自定义适配器中的 getView 方法:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View drawerRow = inflater.inflate(R.layout.drawer_row, parent, false);
TextView drawerRowText = (TextView) drawerRow
.findViewById(R.id.drawer_list_item);
ImageView drawerRowImage = (ImageView) drawerRow
.findViewById(R.id.drawer_list_item_image);
drawerRowText.setText(drawerRowTextValues[position]);
switch (position) {
case 0:
drawerRowImage.setImageResource(R.drawable.content_new_dark);
break;
case 1:
drawerRowImage.setImageResource(R.drawable.location_web_site_dark);
break;
case 2:
drawerRowImage.setImageResource(R.drawable.action_settings_dark);
break;
}
drawerRow.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
System.out.println("drawer list item clicked...");
}
});
return drawerRow;
}
我可以验证事件是否被触发,只是在单击时看不到列表项颜色变化(闪烁),而不是在使用 ArrayAdapter 时。
有什么想法吗?
编辑: 好的,我通过添加 listSelector 得到了几乎想要的行为,如下所示:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- pressed state. -->
<item android:drawable="@color/list_row_pressed_bg"
android:state_pressed="true"/>
</selector>
...使用以下行将该 listSelector 添加到我上面的 listView 中:
android:listSelector="@drawable/drawer_list_selector"
我现在唯一的问题是按下状态颜色没有填充列表中的整个项目行:
