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>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。
