drawerLayout其实是一个布局控件，跟LinearLayout等控件是一样的，但是drawerLayout带有滑动的功能。只要按照drawerLayout的规定布局方式写完布局，就能有侧滑的效果。
1）在DrawerLayout中，第一个子View必须是显示内容的view，并且设置它的layout_width和layout_height属性是match_parent.
2)第二个view是抽屉view,并且设置属性layout_gravity="left|right",表示是从左边滑出还是右边滑出。设置它的layout_
ActionBarDrawerToggle就是DrawerLayout事件的监听器。
ActionBarDrawerToggle有3个方法可以被复写，分别用来实现DrawerLayout打开，关闭，滑动的事件监听：
- onDrawerOpened DrawerLayout滑出时调用
- onDrawerClosed DrawerLayout关闭时调用
- onDrawerSlide DrawerLayout滑动时调用
drawerLayout布局代码：
//主内容 //侧滑菜单
mainactivity.java代码
package com.example.wxj.drawerlayoutlearen;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ListView;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
private TextView view;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
view = (TextView)findViewById(R.id.drawer_text);
mDrawerToggle = new ActionBarDrawerToggle(
this,
mDrawerLayout,
R.string.open,
R.string.close
){
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
view.setText("close");
}
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
view.setText("dakai");
}
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
view.setText("huachu");
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
}
