自定义控件相应的View toplayout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="@+id/top_layout_leftbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="@dimen/top_text_margin_leftright" />
<TextView
android:id="@+id/top_layout_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@android:color/white"
android:layout_centerInParent="true"
android:textSize="@dimen/top_text_size" />
<ImageView
android:id="@+id/top_layout_rightbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="@dimen/top_text_margin_leftright" />
</RelativeLayout>
可以在XMl自定义属性中定义的项目 必须在 attr中定义
<!-- 通用 自定义控件 最顶部的提示栏 -->
<declare-styleable name="TopLayout">
<attr name="leftImage_src" format="reference"></attr>
<attr name="rightImage_src" format="reference"></attr>
<attr name="layout_background" format="reference"></attr>
<attr name="text" format="string"></attr>
<attr name="leftImage_Visiable">
<enum name="visiable" value="0x00000000"></enum>
<enum name="gone" value="0x00000008"></enum>
<enum name="invisiable" value="0x00000004"></enum>
</attr>
<attr name="rightImage_Visiable">
<enum name="visiable" value="0x00000000"></enum>
<enum name="gone" value="0x00000008"></enum>
<enum name="invisiable" value="0x00000004"></enum>
</attr>
<attr name="text_Visiable">
<enum name="visiable" value="0x00000000"></enum>
<enum name="gone" value="0x00000008"></enum>
<enum name="invisiable" value="0x00000004"></enum>
</attr>
</declare-styleable>
使用上自定义控件的地方 testlayout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:topview="http://schemas.android.com/apk/res/com.x2l.onlineedu.mid"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.x2l.onlineedu.mid.object.TopLayout
android:id="@+id/tixian_edit_password_topview"
android:layout_width="match_parent"
android:layout_height="@dimen/top_height"
topview:layout_background="@drawable/top_main"
topview:leftImage_src="@drawable/back"
topview:rightImage_Visiable="gone"
topview:text="提现" >
</com.x2l.onlineedu.mid.object.TopLayout>
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/edit_background"
android:hint="请输入账号登陆密码" />
<ImageView
android:id="@+id/tixian_edit_password_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/tixian_edit_password_btn" />
</LinearLayout>
注意：在使用自定义的控件有时候会报 No
resource identifier found for attribute ‘XXX’ in package等错误
解决方法：命名空间后面的包名应该是AndroidManifest.xml文件中定义的package包名，而不是使用的这个自定义控件所处的包的包名。
