本文实例为大家分享了viewGroup实现点击动画效果展示的具体代码，供大家参考，具体内容如下

public class MyCustomView extends ViewGroup implements View.OnClickListener { private OnMenuItemClickListener mMenuItemClickListener; /** * 点击子菜单项的回调接口 */ public interface OnMenuItemClickListener { void onClick(View view, int pos);

attrs.xml:

菜单布局文件：

<com.admom.mycanvas.view.MyCustomView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:hyman="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/id_menu" android:layout_width="match_parent" android:layout_height="match_parent" hyman:radius="160dp"> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/composer_button"> <ImageView android:id="@+id/id_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@drawable/composer_icn_plus" /> </RelativeLayout> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/composer_music" android:tag="Music" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/composer_place" android:tag="Place" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/composer_sleep" android:tag="Sleep" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/composer_thought" android:tag="Sun" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/composer_with" android:tag="People" /></com.admom.mycanvas.view.MyCustomView>

主界面布局文件：

<?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"> <include layout="@layout/menu_right_bottom"/></RelativeLayout>

在主程序直接使用：

mMenu = (MyCustomView) findViewById(R.id.id_menu);mMenu.setOnMenuItemClickListener(new MyCustomView.OnMenuItemClickListener() { @Override public void onClick(View view, int pos) { Toast.makeText(MainActivity.this, pos + ":" + view.getTag(), Toast.LENGTH_SHORT).show(); }});mMenu.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if(mMenu.isOpen()){ mMenu.toggleMenu(300); } return false; }});
