DrawerLayout使用

1 :DrawerLayout侧边栏用于实现如图所示的效果：

 

              

2：跟布局XML代码如下 ，第一个元素标签为页面显示内容，第二个元素标签用于显示DrawerLayout的布局样式，我用了一个ListView展示。

 

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

    <!-- 第一部分为主页面显示内容-->
    <LinearLayout
        android:id="@+id/main_contant"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="DrawerLayout的学习"
            android:textSize="20dp" />
    </LinearLayout>

    <!--第二部分为DrawerLayout的视图资源-->
    <ListView
        android:id="@+id/left_drawerlayout"
        android:layout_width="180dp"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:background="#ffffcc"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="5dp" />


</android.support.v4.widget.DrawerLayout>

 

3：Activity代码如下，通过点击item跟换了Fragment。Fragment与Activity之间传递参数可通过SetArgument(New Bundle)实现，在Bundle中绑定数据;

package cativity.cyq.drawerlayoutlearn;

import android.support.v4.app.ActionBarDrawerToggle;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import java.util.ArrayList;

import static android.widget.Toast.LENGTH_SHORT;


public class MainActivity extends ActionBarActivity implements AdapterView.OnItemClickListener {

    private DrawerLayout drawerLayout;
    private ListView menuListview;
    private ArrayList<String> menuData;
    private ArrayAdapter<String> menuAdapter;
    private ActionBarDrawerToggle mDrawerToggle;

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

        drawerLayout = (DrawerLayout) findViewById(R.id.root_drawerlayout);
        menuListview = (ListView) findViewById(R.id.left_drawerlayout);
        menuData = new ArrayList<>();
        for (int i = 0; i < 7; i++)
            menuData.add("菜单项" + i);
        menuAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, menuData);
        menuListview.setAdapter(menuAdapter);

        menuListview.setOnItemClickListener(this);

        //监听DrawerLayout的打开和关闭事件
        mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.menubar, R.string.drawerOpen, R.string.drawerClose) {
            @Override
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                Toast.makeText(getApplication(), "打开", LENGTH_SHORT).show();
            }

            @Override
            public void onDrawerClosed(View drawerView) {
                super.onDrawerClosed(drawerView);
                Toast.makeText(getApplication(), "关闭", Toast.LENGTH_SHORT).show();
            }
        };
        drawerLayout.setDrawerListener(mDrawerToggle);

    }

    /* 为DrawerLayout的元素设置监听事件 */
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Toast.makeText(this, "你选择的是:" + position, LENGTH_SHORT).show();
        MyFragment contentFragment = new MyFragment();
       /*通过setArgument(new Bundle())在Fragment的控制器和视图之间传递参数*/
        Bundle args = new Bundle();
        args.putString("fragmentdata", menuData.get(position));
        contentFragment.setArguments(args);

        getFragmentManager().beginTransaction().replace(R.id.main_contant, contentFragment).commit();

        drawerLayout.closeDrawer(menuListview);
    }


}
