DrawerLayout抽屉布局的使用 最简单的侧滑菜单实现

之前项目中遇到需要实现侧滑菜单，自己动手写真是费劲，各种手势判断，各种事件监听，而且效果不是太好，后来知道DrawerLayout实现侧滑真的很方便，用法也非常简单。

DrawerLayout是V4包中的内容，使用如下

（小弟文笔不好，直接附上代码：）

1.首先定义Xml布局，

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <FrameLayout
        android:id="@+id/content_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#F00" />

    <!-- layout_gravity属性控制左右：left/right/ -->
    <ListView
        android:id="@+id/drawer_left"
        android:layout_width="120dp"
        android:layout_height="match_parent"
        android:layout_gravity="left" >
    </ListView>
    <ListView
            android:id="@+id/drawer_right"
            android:layout_width="120dp"
            android:layout_height="match_parent"
            android:layout_gravity="right"
            android:background="#0FF" >
        </ListView>
</android.support.v4.widget.DrawerLayout>

 

 

2.java中主布局代码

package com.example.drawerlayout;

import android.graphics.Color;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.widget.DrawerLayout;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity extends FragmentActivity {

    private DrawerLayout drawerLayout;
    private ListView leftDrawer;
    private ArrayAdapter<String> adapter;
    private final String[] items = new String[] { "选项一：", "选项二：", "选项三：",
            "选项4：", "选项5：", "选项6：" };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        leftDrawer = (ListView) findViewById(R.id.drawer_left);
        adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, items) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                // 设置背填充内容背景色
                TextView tView = (TextView) super.getView(position,
                        convertView, parent);
                tView.setTextColor(Color.BLACK);
                return super.getView(position, convertView, parent);
            }
        };
        leftDrawer.setAdapter(adapter);
        leftDrawer.setBackgroundColor(Color.WHITE);

        // 设置选择模式为单条选中
        leftDrawer.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        leftDrawer.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int pos,
                    long id) {
                leftDrawer.setItemChecked(pos, true);
                NumerFragment frag = NumerFragment.createNumerFragment(pos);
                getSupportFragmentManager().beginTransaction()
                        .replace(R.id.content_view, frag).commit();
                // 关闭所有打开的抽屉
                drawerLayout.closeDrawers();
            }
        });

        // 通过代码：根据重力方向打开指定抽屉
        drawerLayout.openDrawer(Gravity.LEFT);
        // 设置抽屉阴影
        // drawerLayout.setDrawerShadow(R.drawable.ic_launcher, Gravity.LEFT);
        // 设置抽屉空余处颜色
        drawerLayout.setScrimColor(Color.BLUE);
        // 设置抽屉锁定模式 LOCK_MODE_LOCKED_OPEN:锁定 无法滑动； 只能通过代码取消锁定
        // drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);
    }
}
