Android UI实现SlidingMenu侧滑菜单效果

本篇博客给大家分享一个效果比较好的侧滑菜单的Demo，实现点击左边菜单切换Fragment。
效果如下：

 

主Activity代码：

package com.infzm.slidingmenu.demo; 
import Android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.Window; 
import android.widget.ImageView; 
import android.widget.TextView; 
import com.infzm.slidingmenu.demo.fragment.LeftFragment; 
import com.infzm.slidingmenu.demo.fragment.TodayFragment; 
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu; 
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity; 
 
public class MainActivity extends SlidingFragmentActivity implements 
    OnClickListener { 
  private ImageView topButton; 
  private Fragment mContent; 
  private TextView topTextView; 
  @Override 
  public void onCreate(Bundle savedInstanceState) { 
    requestWindowFeature(Window.FEATURE_NO_TITLE); // 无标题 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    initSlidingMenu(savedInstanceState); 
    topButton = (ImageView) findViewById(R.id.topButton); 
    topButton.setOnClickListener(this); 
    topTextView = (TextView) findViewById(R.id.topTv); 
  } 
   
  private void initSlidingMenu(Bundle savedInstanceState) { 
    // 如果保存的状态不为空则得到之前保存的Fragment，否则实例化MyFragment 
    if (savedInstanceState != null) { 
      mContent = getSupportFragmentManager().getFragment( 
          savedInstanceState, "mContent"); 
    } 
    if (mContent == null) { 
      mContent = new TodayFragment(); 
    } 
    // 设置左侧滑动菜单 
    setBehindContentView(R.layout.menu_frame_left); 
    getSupportFragmentManager().beginTransaction() 
        .replace(R.id.menu_frame, new LeftFragment()).commit(); 
    // 实例化滑动菜单对象 
    SlidingMenu sm = getSlidingMenu(); 
    // 设置可以左右滑动的菜单 
    sm.setMode(SlidingMenu.LEFT); 
    // 设置滑动阴影的宽度 
    sm.setShadowWidthRes(R.dimen.shadow_width); 
    // 设置滑动菜单阴影的图像资源 
    sm.setShadowDrawable(null); 
    // 设置滑动菜单视图的宽度 
    sm.setBehindOffsetRes(R.dimen.slidingmenu_offset); 
    // 设置渐入渐出效果的值 
    sm.setFadeDegree(0.35f); 
    // 设置触摸屏幕的模式,这里设置为全屏 
    sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); 
    // 设置下方视图的在滚动时的缩放比例 
    sm.setBehindScrollScale(0.0f); 
  } 
  @Override 
  protected void onSaveInstanceState(Bundle outState) { 
    super.onSaveInstanceState(outState); 
    getSupportFragmentManager().putFragment(outState, "mContent", mContent); 
  } 
   
  public void switchConent(Fragment fragment, String title) { 
    mContent = fragment; 
    getSupportFragmentManager().beginTransaction() 
        .replace(R.id.content_frame, fragment).commit(); 
    getSlidingMenu().showContent(); 
    topTextView.setText(title); 
  } 
  @Override 
  public void onClick(View v) { 
    switch (v.getId()) { 
    case R.id.topButton: 
      toggle(); 
      break; 
    default: 
      break; 
    } 
  } 
} 

侧边栏菜单Fragment

  @Override 
  public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.layout_menu, null);

    String title = null; 
    switch (v.getId()) { 
    case R.id.tvToday: // 今日 
      newContent = new TodayFragment(); 
      title = getString(R.string.today); 
      break; 
    case R.id.tvLastlist:// 往期列表 
      newContent = new LastListFragment(); 
      title = getString(R.string.lastList); 
      break; 
    case R.id.tvDiscussMeeting: // 讨论集会 
      newContent = new DiscussFragment(); 
      title = getString(R.string.discussMeetting); 
      break; 
    case R.id.tvMyFavorites: // 我的收藏 
      newContent = new MyFavoritesFragment(); 
      title = getString(R.string.myFavorities); 
      break; 
    case R.id.tvMyComments: // 我的评论 
      newContent = new MyCommentsFragment(); 
      title = getString(R.string.myComments); 
      break; 
    case R.id.tvMySettings: // 设置 
      newContent = new MySettingsFragment(); 
      title = getString(R.string.settings); 
      break; 
    default: 
      break; 
    } 
    if (newContent != null) { 
      switchFragment(newContent, title); 
    } 
  } 
   
  private void switchFragment(Fragment fragment, String title) { 
    if (getActivity() == null) { 
      return; 
    } 
    if (getActivity() instanceof MainActivity) { 
      MainActivity fca = (MainActivity) getActivity(); 
      fca.switchConent(fragment, title); 
    } 
  } 
}
