android - 如何在滑动菜单中实现项目列表？

Question

我想将项目列表设置为 SlidingMenu 有没有教程？我正在使用 https://github.com/jfeinstein10/SlidingMenu

Answer 1

您可以在库中的 ExampleListActivity 中找到它。

要首先将列表项添加到滑动菜单中，您需要在主菜单上使用 FrameLayout。

MainActivity.xml(在布局文件夹中)

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />

然后创建一个leftlist.xml(左侧菜单的列表)

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/list_padding"
android:paddingRight="@dimen/list_padding" />

之后创建一个 menu_frame.xml(用于保存左侧的列表)

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/menu_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />

还有一个 row.xml(自定义每一行的 View )

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal" >

<TextView
    android:id="@+id/row_title1"
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:padding="10dp"

</LinearLayout>

然后有个SampleListFragment.java(写list的名字)

   public class SampleListFragment extends ListFragment {

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.leftlist, null);
}

public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
    SampleAdapter adapter = new SampleAdapter(getActivity());
    adapter.add(new SampleItem("menu left A"));
    adapter.add(new SampleItem("menu left B"));
    adapter.add(new SampleItem("menu left C"));
    adapter.add(new SampleItem("menu left D"));
    adapter.add(new SampleItem("menu left A"));
    setListAdapter(adapter);

}

private class SampleItem {
    public String tag;
    public int iconRes;
    public SampleItem(String tag, int iconRes) {
        this.tag = tag; 
        this.iconRes = iconRes;
    }
}

public class SampleAdapter extends ArrayAdapter<SampleItem> {

    public SampleAdapter(Context context) {
        super(context, 0);
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, null);
        }
        ImageView icon = (ImageView) convertView.findViewById(R.id.row_icon);
        icon.setImageResource(getItem(position).iconRes);
        TextView title = (TextView) convertView.findViewById(R.id.row_title);
        title.setText(getItem(position).tag);

        return convertView;
    }

}
   }

你需要一个baseactivity来显示滑动/ Action 条的效果BaseActivity.java(配置你的滑动菜单效果)

   public class BaseActivity extends SlidingFragmentActivity {
SlidingMenu menu;
private int mTitleRes;
protected ListFragment mFrag;

public BaseActivity(int titleRes) {
    mTitleRes = titleRes;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setTitle(mTitleRes);

    // set the Behind View
    setBehindContentView(R.layout.menu_frame);
    if (savedInstanceState == null) {
        FragmentTransaction t = this.getSupportFragmentManager().beginTransaction();
        mFrag = new SampleListFragment();
        t.replace(R.id.menu_frame, mFrag);
        t.commit();
    } else {
        mFrag = (ListFragment)this.getSupportFragmentManager().findFragmentById(R.id.menu_frame);
    }

    // customize the SlidingMenu
    SlidingMenu sm = getSlidingMenu();
    sm.setShadowWidthRes(R.dimen.shadow_width);
    sm.setShadowDrawable(R.drawable.shadow);
    sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
    sm.setFadeDegree(0.35f);
    sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);



}


   }

然后在您的 MainActivity.java 上扩展 baseactivity(只需在您的 oncreate 中调用左侧菜单)

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

          getSlidingMenu().setMode(SlidingMenu.LEFT);
    getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);

    getSupportFragmentManager()
    .beginTransaction()
    .replace(R.id.menu_frame, new SampleListFragment())
    .commit();
    }

这就是我为我的应用程序所做的，我不确定这是正确的还是错误的方法，但如果您有任何问题，请随时提问。当然，您必须将 res/drawable 文件夹中的 shadow.xml 和 shadowright.xml 复制到您的应用程序
