android 怎样让drawerlayout设置的侧滑菜单的内容充满屏幕
现在侧滑菜单使用很多，大都是通过SlidingMenu实现。现在也可以通过DrawerLayout
创建抽屉布局
frament_content.xml
[html] view plaincopy
?xml version="1.0" encoding="utf-8"?
LinearLayout xmlns:android=""
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
TextView
android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="25sp" /
/LinearLayout
activity_main.xml
[html] view plaincopy
android.support.v4.widget.DrawerLayout xmlns:android=""
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
!-- The main content view --
FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
/FrameLayout
!-- The navigation view --
ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#ffffcc"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
/ListView
/android.support.v4.widget.DrawerLayout
然后新建一个类继承Fragment类
[java] view plaincopy
/**
* ContentFragment.java
* 版权所有(C) 2015
* 创建者:cuiran 2015-1-3 下午3:25:44
*/
package com.cayden.drawerlayoutdemo;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
/**
* TODO
* @author cuiran
* @version 1.0.0
*/
public class ContentFragment extends Fragment {
private TextView textView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_content, container, false);
textView = (TextView) view.findViewById(R.id.textView);
String text = getArguments().getString("text");
textView.setText(text);
return view;
}
}
完成Activity代码
[java] view plaincopy
package com.cayden.drawerlayoutdemo;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = (String) getTitle();
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
menuLists = new ArrayListString();
for (int i = 0; i 5; i++)
menuLists.add("菜单0" + i);
adapter = new ArrayAdapterString(this,
android.R.layout.simple_list_item_1, menuLists);
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(this);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close) {
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle("请选择");
invalidateOptionsMenu(); // Call onPrepareOptionsMenu()
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
//开启ActionBar上APP ICON的功能
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
boolean isDrawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_websearch).setVisible(!isDrawerOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
//将ActionBar上的图标与Drawer结合起来
if (mDrawerToggle.onOptionsItemSelected(item)){
return true;
}
switch (item.getItemId()) {
case R.id.action_websearch:
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
Uri uri = Uri.parse("");
intent.setData(uri);
startActivity(intent);
break;
}
return super.onOptionsItemSelected(item);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
//需要将ActionDrawerToggle与DrawerLayout的状态同步
//将ActionBarDrawerToggle中的drawer图标，设置为ActionBar中的Home-Button的Icon
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
@Override
public void onItemClick(AdapterView? arg0, View arg1, int position,
long arg3) {
// 动态插入一个Fragment到FrameLayout当中
Fragment contentFragment = new ContentFragment();
Bundle args = new Bundle();
args.putString("text", menuLists.get(position));
contentFragment.setArguments(args);
FragmentManager fm = getFragmentManager();
fm.beginTransaction().replace(R.id.content_frame, contentFragment)
.commit();
mDrawerLayout.closeDrawer(mDrawerList);
}
}

Q1: android webView 加载H5页面如何实现左右侧滑效果返回上一页？
不是原生Activity没关系 只要继承Activity就没问题，监听滑动事件就行了
Q2: android 侧滑菜单可以有两个吗
既然是侧滑，无非就是在巴掌大的屏幕，塞入大概两巴掌大的布局，需要滑动可以出现另一个，既然这样，大家为啥不考虑使用Android提供的HorizontalScrollView呢~
如果使用HorizontalScrollView，还需要在ACTION_DOWN , ACTION_MOVE里面去监听，判断，不断改变控件位置了么? NO！！！HorizontalScrollView本身就带了滑动的功能~~
Q3: android 如何实现边缘拖动侧滑？
据需求需要自己自定义一个ListView来实现该功能，接下来先贴出代码再讲解具体的实现
