Question

我有一个应用程序，其中我有一个带有菜单按钮的导航面板，我想在其上应用导航抽屉，目前占用整个屏幕，但我想通过应用导航将其限制在屏幕的3/4抽屉上面，但我从来没有碰过导航抽屉之前所以没有任何线索，任何帮助或指导将是伟大的。也经历了一些文件，并感到困惑:( 这是我的代码：

这是导航面板的布局类：

此处还有navigationpanelfragment.java： --update ----

        }

        highlightedTextView.setTextColor(getResources().getColor(R.color.dark_orange));

    }

}

这是我的acitvity_main.xml（它可以工作，在滑动时显示一个空白面板）

<?xml version="1.0" encoding="utf-8"?>

这是添加导航抽屉的好文章：http://developer.android.com/training/implementing-navigation/nav-drawer.html

您的导航抽屉显示一个空白面板，因为您的activity_main.xml中的抽屉视图是一个ListView（您尚未设置任何数据）。

您希望将此视图设为您的片段。

您的activity_main.xml文件应如下所示。确保将fragment标记上的类替换为导航片段的正确类。

<?xml version="1.0" encoding="utf-8"?>
<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" >

    <!-- This fragment container is your the place to put your activities content -->

    <FrameLayout
        android:id="@+id/fragment_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/altercolor2" />

    <!--
    This is your navigation drawer. You can adjust the width here, but it should
    be between 240dp and 320dp
    -->

    <fragment
        android:id="@+id/drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        class="com.yourapp.NavigationPanelFragment" />

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

您的MainActivity应如下所示：

public class MainActivity extends AbsBaseaActivity implements OnBackStackChangedListener {
    public static final int REQUEST_CODE_LIST = 100;

    private Fragment mDrawer;
    private ActionBarDrawerToggle mDrawerToggle;

            }
        }
    }
}

请注意，导航抽屉的状态由抽屉布局管理。 DrawerLayout和抽屉片段在onCreate方法中绑定。

如果遇到麻烦，请参阅我提到的文章。

---编辑----

以下是我在应用中使用的一项活动。它显示了如何添加抽屉切换（我发布的链接也显示了这一点）。

您应该能够将其与当前活动合并，并拥有一个有效的导航抽屉。

public class SampleActivity extends AbsBaseaActivity {

    private Fragment mDrawer;
    private ActionBarDrawerToggle mDrawerToggle;
    private DrawerLayout mDrawerLayout;

    @Override public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerMenuItems = getResources().getStringArray(R.array.home_menu_drawer_titles);
        mDrawer = (fragment) findViewById(R.id.drawer);

        /* Set up the drawer toggle */
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_closed) {

            /** Called when a drawer has settled in a completely closed state. */
            public void onDrawerClosed(View view) {
                getActionBar().setTitle(R.string.activity_title);
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                getActionBar().setTitle(R.string.app_name);
            }
        };

        // Set the drawer toggle as the DrawerListener
        mDrawerLayout.setDrawerListener(mDrawerToggle);

    }

    /**
     * Backward-compatible version of {@link ActionBar#getThemedContext()} that
     * simply returns the {@link android.app.Activity} if <code>getThemedContext</code> is unavailable.
     */
    @TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH) private Context getActionBarThemedContextCompat() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
            return getActionBar().getThemedContext();
        } else {
            return this;
        }
    }

    @Override protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        mDrawerToggle.syncState();
        mDrawer.setItemChecked(0, true);
    }

    @Override public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    @Override public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case android.R.id.home:
            if (mDrawerLayout.isDrawerOpen(mDrawer)) {
                mDrawerLayout.closeDrawer(mDrawer);
            } else {
                mDrawerLayout.openDrawer(mDrawer);
            }
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

你可以从下面的链接获取导航抽屉的源颂歌

http://hmkcode.com/android-creating-a-navigation-drawer/

将其复制到工作区，或从现有源代码中打开为新的Android项目。

右键点击项目＆gt;属性＆gt; java buildpath＆gt;添加外部jar＆gt;从安装的android sdks中选择最新的V13支持库并按顺序导出并勾选jar v13

再次右键单击项目＆gt;属性＆gt; android＆gt;选择abs库。 [google for library]

U将获得无错误的工作项目

以上所有答案都很棒，但是我发现在现有代码中添加它有点困难，因此我创建了一个新类，该类使用动画和LayoutInflater添加视图并将导航抽屉移至您可以使用的活动中也有片段。

NavigationDrawer.java

import android.app.Activity;
import android.support.constraint.ConstraintLayout;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.animation.Animation;
import android.view.animation.TranslateAnimation;

import static android.content.Context.LAYOUT_INFLATER_SERVICE;

public class NavigationDrawer {

//State is the visible state
private Boolean state = false, Transition = false;
private ConstraintLayout mainView;
private ConstraintLayout navigationLayout;
private Animation show, hide;

public NavigationDrawer(Activity activity, ConstraintLayout view) {

    this.mainView = view;

    LayoutInflater layoutInflater = (LayoutInflater) 
activity.getSystemService(LAYOUT_INFLATER_SERVICE);
    navigationLayout = (ConstraintLayout) layoutInflater.inflate(R.layout.nav_drawer, 
mainView, false);

    DisplayMetrics displayMetrics = new DisplayMetrics();
    activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);

    //Show animation
    show = new TranslateAnimation(-displayMetrics.widthPixels, 0, 0, 0);
    show.setDuration(500);
    show.getFillAfter();
    show.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {
            Transition = true;
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            Transition = false;
            state = true;
        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }
    });

    //Hide animation
    hide = new TranslateAnimation(0, -displayMetrics.widthPixels, 0, 0);
    hide.setDuration(500);
    hide.getFillAfter();

    hide.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {
            Transition = true;
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            Transition = false;
            state = false;
        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }
    });
}

public void toggle() {
    if (!Transition) {
        if (!state) {
            mainView.addView(navigationLayout);
            navigationLayout.startAnimation(show);
        } else {
            navigationLayout.startAnimation(hide);
            mainView.removeView(navigationLayout);
        }
    }
}
}

要使用此类。

NavigationDrawer navigationDrawer = new 
NavigationDrawer(this,user_activity_main_layout);

//To toggle it
navigationDrawer.toggle();

此处 user_activity_main_layout 是根ConstrainLayout的ID，您可以选择所需的任何内容。这很完美。

如何将导航抽屉添加到现有代码中？
