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

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

android:id="@+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="25sp" />


activity_main.xml

[html] view plaincopy
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >



android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >




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" >




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;

import java.util.ArrayList;

import android.app.Activity;
import android.app.Fragment;
import android.app.FragmentManager;
import android.content.Intent;
import android.content.res.Configuration;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivity extends Activity implements OnItemClickListener {

private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ArrayList menuLists;
private ArrayAdapter adapter;
private ActionBarDrawerToggle mDrawerToggle;
private String mTitle;

@Override
protected void onCreate(Bundle savedInstanceState) {
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 ArrayList();
for (int i = 0; i < 5; i++)
menuLists.add("菜单0" + i);
adapter = new ArrayAdapter(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("http://www.baidu.com");
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);
}

}

布局文件中使用drawerLayout ，下面包含两个区，主内容区的布局代码要放在侧滑菜单布局的前面，侧滑菜单的部分的布局可以设置layout_gravity属性来表示在左边还是右边。
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>

看代码很清楚，但是如果说要让侧滑出来的菜单内容占满整个屏幕的话，需要自己知道屏幕的width，ListView也就是菜单布局width设置一样就可以了（不过设置为math_parent也大概只占了百分之90左右，并不能完全覆盖掉）。
