android studio和eclipse中自定义组合控件的不同写法

带自定义属性的组合控件在AS和eclipse中的写法发生了一些变化，先上代码再解释

主要体现在两个方面：自定义属性的获取和命名空间的声明。具体看代码

AS中的写法

1、布局文件，view_mine_item.xml

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:background="@drawable/mine_item_click_selector" android:layout_height="70dp"> <ImageView android:id="@+id/iv_image" android:src="@drawable/ssdk_oks_classic_evernote" android:layout_margin="15dp" android:layout_centerVertical="true" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/tv_title" android:layout_toRightOf="@id/iv_image" android:layout_centerVertical="true" android:textSize="18sp" android:text="北京市" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <ImageView android:src="@drawable/enter_pressed" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginRight="15dp" android:layout_width="15dp" android:layout_height="30dp" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:layout_alignParentBottom="true" android:background="@color/gry_c"/> </RelativeLayout>

2.自定义属性，在values中创建attrs.xml文件

<?xml version="1.0" encoding="utf-8"?> <resources> <declare-styleable name="MineItemClickView"> <-- 与你的自定义控件的名称相同--> <attr name="titleText" format="string"/> <attr name="titleImage" format="reference"/> </declare-styleable> </resources>

3. 创建自定义控件 MineItemClickView.java

public class MineItemClickView extends RelativeLayout { private ImageView mIamge; private TextView mTitle; public MineItemClickView(Context context, AttributeSet attrs) { super(context, attrs); //加载attrs.xml文件中的自定义属性 TypedArray ta = context.obtainStyledAttributes(attrs, R.styleable.MineItemClickView); CharSequence title = ta.getText(R.styleable.MineItemClickView_titleText); int iconId = ta.getResourceId(R.styleable.MineItemClickView_titleImage, 0); View view = LayoutInflater.from(context).inflate(R.layout.view_mine_item,this,true); mIamge = (ImageView) view.findViewById(R.id.iv_image); mTitle = (TextView) view.findViewById(R.id.tv_title); //赋值 mTitle.setText(title); mIamge.setImageResource(iconId); ta.recycle(); } /** * 设置标题 * @param text */ public void setTitleText(String text){ mTitle.setText(text); } /** * 设置图标 * @param resId */ public void setTitleImage(int resId){ mIamge.setImageResource(resId); } <span style="font-size:12px;">}</span>

4.使用（注意命名空间是yun:android="http://schemas.android.com/apk/res-auto"）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:yun="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.zsc.blacksmith.fragment.OneFragment"> <pre name="code" class="html"> <com.zsc.blacksmith.view.widget.MineItemClickView android:id="@+id/micv_beijing" android:layout_width="match_parent" android:layout_height="wrap_content" yun:titleImage="@drawable/ssdk_oks_classic_evernote" yun:titleText="北京市" /> </LinearLayout>

Eclipse中的写法

1.同AS中第一步

2.自定义属性

<?xml version="1.0" encoding="utf-8"?> <resources> <attr name="titleText" format="string"/> <attr name="titleImage" format="reference"/> </resources> 3. 创建自定义控件 MineItemClickView.java

public class MineItemtClickView extends RelativeLayout{ //命名空间 private static final String NAMESPACE = "http://schemas.android.com/apk/res/com.example.mymy"; private ImageView mIamge; private TextView mTitle; public MineItemtClickView(Context context) { super(context); } public MineItemtClickView(Context context, AttributeSet attrs) { super(context, attrs); initView(context); String title = attrs.getAttributeValue(NAMESPACE, "titleText"); int icon = attrs.getAttributeResourceValue(NAMESPACE, "titleImage",0); setTitle(title); mIamge.setImageResource(icon); } private void setTitle(String title) { mTitle.setText(title); } private void initView(Context context){ View.inflate(context, R.layout.view_mine_item, this); mIamge = (ImageView) findViewById(R.id.iv_image); mTitle = (TextView) findViewById(R.id.tv_title); } } 4.使用（注意命名空间是yun:android="http://schemas.android.com/apk/res/android"）

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:yun="http://schemas.android.com/apk/res/包名" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" > <com.zsc.blacksmith.view.widget.MineItemClickView android:layout_width="match_parent" android:layout_height="wrap_content" <pre name="code" class="html"><pre name="code" class="html"> yun:titleImage="@drawable/ssdk_oks_classic_evernote" yun:titleText="北京市"/>

</RelativeLayout>
