2、模拟菜单的效果,增加动画,布局显示的时候增加一个渐渐底部生气的效果,隐藏的时候增加一个缓缓下落的效果,显示菜单动画文件:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="0"
android:toXDelta="0"
android:fromYDelta="00"
android:toYDelta="140"
android:duration="200" />
</set>
隐藏菜单动画文件:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="0"
android:toXDelta="0"
android:fromYDelta="140"
android:toYDelta="00"
android:duration="200" />
</set>
动画调用:
/**
* 显示菜单栏, 重新实现的Option menu.
* */
private void showAppMenu() {
if (menuShowAnimation == null) {
menuShowAnimation = AnimationUtils
.loadAnimation(mContext, R.anim.menuhide);
}
myLayout.startAnimation(menuShowAnimation);
myLayout.setVisibility(View.VISIBLE);
}
/**
* 隐藏菜单栏, 重新实现的Option menu.
* */
private void hideAppMenu() {
myLayout.setVisibility(View.GONE);
if (menuHideAnimation == null)
menuHideAnimation =AnimationUtils
.loadAnimation(mContext, R.anim.menushow);
myLayout.startAnimation(menuHideAnimation);
}
3、控制菜单的隐藏和显示,需要重写三个方法public boolean onCreateOptionsMenu(Menu menu),
public boolean dispatchKeyEvent(KeyEvent event) 和public boolean dispatchTouchEvent(MotionEvent event)
@Override
public boolean onCreateOptionsMenu(Menu menu) {
if(mCustomMenu==null)
mCustomMenu=new CustomMenu(CustomMenuActivity.this,CustomMenuActivity.this);
mCustomMenu.CreateMenu();
return false;
}
@Override
public boolean dispatchKeyEvent(KeyEvent event) {
if(mCustomMenu!=null)
return mCustomMenu.dispatchKeyEvent(event,super.dispatchKeyEvent(event));
return super.dispatchKeyEvent(event);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
if(mCustomMenu!=null)
return mCustomMenu.dispatchTouchEvent(event,super.dispatchTouchEvent(event));
return super.dispatchTouchEvent(event);
}
4、实现菜单点击时候被点击菜单状态的般变化,这里我使用了selector来实现,菜单我使用ImageButton将selector赋值给ImageButton 的background即可:
一个菜单项
<ImageButton
android:layout_marginLeft="8dip"
android:id="@+id/menu_btn_index"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/menu_index_selector"
/>
menu_index_selector 文件内容如下:
<?xml version="1.0" encoding="utf-8"?>

-->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false"
android:drawable="@drawable/menu_index" />
<item android:state_pressed="true"
android:drawable="@drawable/menu_index1" />
<item android:state_focused="true"
android:drawable="@drawable/menu_index1" />
<item
android:drawable="@drawable/menu_index" />
</selector>
5、页面的调用使用:<include>标签来进行引用:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<include layout="@layout/menu_layout"/>
</RelativeLayout>
