Android DrawerLayout实现左右侧滑

浏览数：24 / 时间：2015年06月11日

首先， DrawerLayout这个类是在Support Library里的，需要加上android-support-v4.jar这个包。然后程序中用时在前面导入import android.support.v4.widget.DrawerLayout; 如果找不到这个类，首先用SDK Manager更新一下Android Support Library，然后在Android SDK/extras/android/support/v4

路径下找到android-support-v4.jar，复制到项目的libs路径，将其Add to Build Path.

http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html

打开抽屉： DrawerLayout .openDrawer(); 关闭抽屉：DrawerLayout.closeDrawer( );

要注意这几个原则：

1.主view(content view) 必须是drawerlayout的第一个子节点

2.主view宽和高必需match_parent

3.drawer view必须指定android:layout_gravity属性，如果值为“start”，会根据系统的语言顺序自动决定从左滑还是从右

滑

4. drawer view宽度不能太宽，最好不要超过320dp

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/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" >
        <TextView android:text="@string/hello_world" android:layout_width="wrap_content"
            android:id="@+id/textView1"
            android:layout_height="wrap_content" />
    </FrameLayout>
    <!-- The navigation drawer -->
    <ListView 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"/>
</android.support.v4.widget.DrawerLayout>

public class MainActivity extends ActionBarActivity implements  ResponseListener<String> {
    private TextView mTextView;
    private ListView mListView;
    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mDrawerToggle;
    private ArrayList<String> list=new ArrayList<String>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        list.add("test1");
        list.add("test2");
        list.add("test3");
        list.add("test4");
        list.add("test5");

        mListView=(ListView)findViewById(R.id.left_drawer);
        mListView.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, list));

        mTextView=(TextView)findViewById(R.id.textView1);

        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                mTextView.setText(list.get(position));
                mDrawerLayout.closeDrawer(mListView);
               // mDrawerLayout.openDrawer(mListView);
            }
        });

    }
