1.This tag and its children can be replaced by one <TextView/> and a compound drawable
xml 想要实现textview旁有个imageview标识。
<LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:padding="10dp" android:gravity="center_vertical"> <TextView android:id="@+id/nick_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="5dip" android:gravity="center_vertical" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="@color/black" android:singleLine="true" /> <ImageView android:id="@+id/_ic" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="4dp" android:background="@drawable/sina_icon_small"/> </LinearLayout>
改善提示,可以使用
android:drawableTopandroid:drawableBottomandroid:drawableLeftandroid:drawableRightandroid:drawablePadding
这些属性设置textview的图片属性,对应的代码为TextView.setCompoundDrawable*()等。
改善后
<TextView android:id="@+id/nick_name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="5dip" android:gravity="center_vertical" android:textAppearance="?android:attr/textAppearanceMedium" android:textColor="@color/black" android:singleLine="true" android:text="@string/account_center" android:drawableRight="@drawable/sina_icon_small" android:drawablePadding="4dp"/>
效果图:
2. [Accessibility] Missing contentDescription attribute on image
在一些不显示文本的控件中被要求添加android:contentDescription=""来描述控件的作用。
android:contentDescription
- setContentDescription(CharSequence)
Making Applications Accessible
Defines text that briefly describes content of the view. This property is used primarily for accessibility. Since some views do not have textual representation this attribute can be used for providing such.
Must be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character.
This may also be a reference to a resource (in the form "@[package:]type:name
") or theme attribute (in the form "?[package:][type:]name
") containing a value of this type.
This corresponds to the global attribute resource symbolcontentDescription
.
