Android开源项目SlidingMenu的学习笔记(二)
在前面已经介绍了SlidingMenu的用法:Android开源项目SlidingMenu的学习笔记(一),接下来再深入学习下,根据滑出项的Menu切换到对应的页面
目录结构:
点击Bluetooth可以切换到相应的界面
关键代码
MainActivity.java
package com.dzt.slidingmenudemo; import android.app.Fragment; import android.app.FragmentManager; import android.app.FragmentTransaction; import android.os.Bundle; import android.util.Log; import com.dzt.slidingmenudemo.fragment.BluetoothFragment; import com.dzt.slidingmenudemo.fragment.DisplayFragment; import com.dzt.slidingmenudemo.fragment.HomeFragment; import com.dzt.slidingmenudemo.fragment.MenuFragment; import com.dzt.slidingmenudemo.fragment.WifiFragment; import com.dzt.slidingmenudemo.fragment.MenuFragment.OnMenuListOnItemClickListener; import com.slidingmenu.lib.SlidingMenu; import com.slidingmenu.lib.app.SlidingActivity; /** * 根据不同的Menu切换到相应的Fragment * * @author Administrator * */ public class MainActivity extends SlidingActivity implements OnMenuListOnItemClickListener { private SlidingMenu mChannelMenu; @Override public void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); // 设置标题栏的标题 setTitle("测试SlidingMenu"); setContentView(R.layout.content_frame); initChannelMenu(); } private void initChannelMenu() { setBehindContentView(R.layout.menu_frame); // 创建SlidingMenu对象 mChannelMenu = getSlidingMenu(); // 设置侧滑栏菜单位置,这里在左边。拉动菜单时,会从左边弹出 mChannelMenu.setMode(SlidingMenu.LEFT); // 设置触摸的范围,这里设置全屏 mChannelMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); // 设置阴影的宽度,查看上面第二张效果图,靠右边的位置,有一个阴影过渡。就是这个东西 mChannelMenu.setShadowWidthRes(R.dimen.shadow_width); // 这里是阴影效果,可以设置图片或者一个颜色过渡 mChannelMenu.setShadowDrawable(R.drawable.shadow); // 设置后面间距,侧滑栏和原来界面间距 mChannelMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset); // 边框的角度,这里指边界地方 mChannelMenu.setFadeDegree(0.35f); // 设置触摸屏幕的模式 mChannelMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); // 设置SlidingMenu的内容 FragmentTransaction fragmentTransaction = getFragmentManager() .beginTransaction(); MenuFragment menuFragment = new MenuFragment(); menuFragment.setOnMenuListOnItemClickListener(this); fragmentTransaction.replace(R.id.menu_frame, menuFragment); fragmentTransaction.replace(R.id.content_frame, new HomeFragment()); fragmentTransaction.commit(); } @Override public void onBackPressed() { if (mChannelMenu.isMenuShowing()) { // 隐藏SlidingMenu,这里的Content就是我们的主Activity mChannelMenu.showContent(); } else { super.onBackPressed(); } } @Override public void onSelectItem(int position, String title) { // TODO Auto-generated method stub System.out.println("onSelectItem title = " + title); Fragment fragment = null; switch (position) { case 0: fragment = new HomeFragment(); break; case 1: fragment = new WifiFragment(); break; case 2: fragment = new BluetoothFragment(); break; case 3: fragment = new DisplayFragment(); break; default: break; } if (fragment != null) { FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .replace(R.id.content_frame, fragment).commit(); // update selected item and title, then close the drawer setTitle(title); mChannelMenu.showContent(); } else { // error in creating fragment Log.e("MainActivity", "Error in creating fragment"); } } }滑出的Fragment MenuFragment.java
package com.dzt.slidingmenudemo.fragment; import java.util.ArrayList; import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ListView; import com.dzt.slidingmenudemo.MenuListAdapter; import com.dzt.slidingmenudemo.R; import com.dzt.slidingmenudemo.domain.MenuItem; public class MenuFragment extends Fragment implements OnItemClickListener { private ListView mLv; private String[] mMenuTitles; private ArrayList<MenuItem> mMenuItem; private MenuListAdapter mAdapter; private OnMenuListOnItemClickListener mListener; public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.menu_fragment, container, false); initWidgets(rootView); return rootView; } private void initWidgets(View rootView) { mLv = (ListView) rootView.findViewById(R.id.left_menu); mMenuTitles = getResources().getStringArray(R.array.menu_title); mMenuItem = new ArrayList<MenuItem>(); for (int i = 0; i < mMenuTitles.length; i++) { MenuItem item = null; if (i == 2) { item = new MenuItem(mMenuTitles[i], R.drawable.ic_launcher, "18", true); } else if (i == 4) { item = new MenuItem(mMenuTitles[i], R.drawable.ic_launcher, "40", true); } else { item = new MenuItem(mMenuTitles[i], R.drawable.ic_launcher); } mMenuItem.add(item); } mAdapter = new MenuListAdapter(getActivity(), mMenuItem); mLv.setAdapter(mAdapter); mLv.setOnItemClickListener(this); } @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // TODO Auto-generated method stub mLv.setItemChecked(position, true); mLv.setSelection(position); if (mListener != null) { mListener.onSelectItem(position, mMenuTitles[position]); } } public void setOnMenuListOnItemClickListener( OnMenuListOnItemClickListener listener) { mListener = listener; } public interface OnMenuListOnItemClickListener { public void onSelectItem(int position, String title); } }点击Menu后,在MainActivity中实现了点击的监听器,就会切换到相应的页面
