SlidingMenu是github上比較火开源库。很强大,不但但是简单的设置实现两側滑动菜单,还能够设置菜单的阴影、渐变色、划动模式等。

怎样使用
要想可以实现SlidingMenu的效果,首先必需要将它作为libary导入到你的project。
注意:slidingMenu_library类库本身自带了android-support-v4.jar文件,而我们自己的project一般也带有这个文件,假设两个文件的SHA-1值不一样,可能会出现
找不到类的异常。我的做法是删除掉自己项目里面的android-support-v4.jar。
API演示样例代码
package com.example.slidingmenu_left; import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.Window; import com.example.slidingmenu_left.fragment.MenuFragment;
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity; public class MainActivity extends SlidingFragmentActivity { private SlidingMenu slidingMenu; @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE); // 内容页布局
setContentView(R.layout.content); // 设置側拉条目布局
setBehindContentView(R.layout.menu_frame); // 获取側拉栏目对象
slidingMenu = getSlidingMenu(); /*
* SlidingMenu.TOUCHMODE_FULLSCREEN 全屏触摸拖拽有效
* SlidingMenu.TOUCHMODE_MARGIN 拖拽边缘有效
* SlidingMenu.TOUCHMODE_NONE 全屏不响应触摸拖拽事件
*/
slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN); // 设置内容显示页相应的dp大小
slidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset); // // 设置左側側拉栏目的dp大小
// slidingMenu.setBehindWidthRes(140);// 注意这里面140的单位是像素 /*
* SlidingMenu.LEFT
* SlidingMenu.RIGHT
* SlidingMenu.LEFT_RIGHT
*/
// 设置側拉栏目的位置
slidingMenu.setMode(SlidingMenu.LEFT); // 给側拉栏目和右側内容页区分开(竖线)
slidingMenu.setShadowDrawable(R.drawable.shadow); // 设置(竖线)的宽度
slidingMenu.setShadowWidthRes(R.dimen.shadow_width); // fragment去替换布局中节点
Fragment fragment = new MenuFragment();
getSupportFragmentManager().beginTransaction()// 开启事务
.replace(R.id.menu, fragment, "MENU")//替换布局
.commit();// 提交事务 } /**
* 当前类中做替换当前显示内容界面的操作
* @author wuseyukui

*/
public void switchFragment(Fragment fragment) {
if (fragment != null) {
getSupportFragmentManager().beginTransaction()
.replace(R.id.content_frame, fragment, "CONTENT")
.commit();
slidingMenu.toggle();
}
} }
package com.example.slidingmenu_left.fragment; import java.util.ArrayList;

public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Fragment fragment = null;
switch (position) {
case 0:

break;

} swithFragment(fragment);
}
});
} private void swithFragment(Fragment fragment) {
if (getActivity() instanceof MainActivity) {
((MainActivity)getActivity()).switchFragment(fragment);
}
} private List<String> initData() {
ArrayList<String> arrayList = new ArrayList<String>();
arrayList.add("栏目1");
arrayList.add("栏目2");
arrayList.add("栏目3");
arrayList.add("栏目4");

return arrayList;
}
}
