Question

我实现了一个自定义listView，如下所示： http://www.tutecentral.com/android-custom-navigation-drawer/但我无法为列表中的商品获得正确的高度。标题和部分布局都太大（高度）。

这是我的xml布局文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:facebook="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<LinearLayout
    android:id="@+id/profileLayout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_marginTop="0dp"
    >


    <com.facebook.widget.ProfilePictureView
        android:id="@+id/drawer_profilePicture"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        />

    <TextView
        android:id="@+id/drawer_profileName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:layout_weight="1"
        />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_marginTop="0dp">
        <Button
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"/>
        <Button
            android:id="@+id/button_logout"
            android:text="Logout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"/>

    </LinearLayout>

</LinearLayout>

<LinearLayout
    android:id="@+id/sectionLayout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:gravity="center_horizontal"
    android:minHeight="?android:attr/listPreferredItemHeight"
    >

    <TextView
        android:id="@+id/drawer_sectionName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceSmall"
        />


</LinearLayout>

<LinearLayout
    android:id="@+id/headerLayout"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:orientation="vertical"
    android:layout_marginTop="0dp"
    >

    <TextView
        android:id="@+id/drawer_headerName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:paddingLeft="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        />

    <View
        android:layout_width="match_parent"
        android:layout_height="2dp"
        android:layout_marginBottom="1dp"
        android:layout_marginTop="1dp"
        android:background="#DADADC" ></View>


</LinearLayout>

有什么建议吗？

[编辑]这是我的customDrawerAdapter getview代码：

    public class CustomDrawerAdapter extends ArrayAdapter<DrawerItem> {

private final JSONObject userProfile;
Context context;
List<DrawerItem> drawerItemList;
int layoutResID;

public CustomDrawerAdapter(Context context, int layoutResourceID,
                           List<DrawerItem> listItems, JSONObject userProfile) {
    super(context, layoutResourceID, listItems);
    this.context = context;
    this.drawerItemList = listItems;
    this.layoutResID = layoutResourceID;
    this.userProfile = userProfile;

}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub

    DrawerItemHolder drawerHolder;
    View view = convertView;

    if (view == null) {
        LayoutInflater inflater = ((Activity) context).getLayoutInflater();
        drawerHolder = new DrawerItemHolder();

        view = inflater.inflate(layoutResID, parent, false);
        drawerHolder.profileName = (TextView) view
                .findViewById(R.id.drawer_profileName);
        drawerHolder.profilePicture = (ProfilePictureView) view.findViewById(R.id.drawer_profilePicture);
        drawerHolder.sectionName = (TextView) view.findViewById(R.id.drawer_sectionName);
        drawerHolder.headerName = (TextView) view.findViewById(R.id.drawer_headerName);

        drawerHolder.buttonLogout = (Button) view.findViewById(R.id.button_logout);
        drawerHolder.buttonLogout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ParseUser.logOut();
                Intent intent = new Intent(getContext(), LoginActivity.class);
                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                view.getContext().startActivity(intent);
            }
        });


        drawerHolder.profileLayout = (LinearLayout) view.findViewById(R.id.profileLayout);
        drawerHolder.sectionLayout = (LinearLayout) view.findViewById(R.id.sectionLayout);
        drawerHolder.headerLayout = (LinearLayout) view.findViewById(R.id.headerLayout);

        view.setTag(drawerHolder);

    } else {
        drawerHolder = (DrawerItemHolder) view.getTag();

    }

    DrawerItem dItem = this.drawerItemList.get(position);

    if (dItem.isHeader()) {
        drawerHolder.profileLayout.setVisibility(LinearLayout.INVISIBLE);
        drawerHolder.sectionLayout.setVisibility(LinearLayout.INVISIBLE);
        drawerHolder.headerLayout.setVisibility(LinearLayout.VISIBLE);
        drawerHolder.headerName.setText(dItem.getHeaderName());

    } else if (dItem.getProfilePicture() == 0){
        drawerHolder.profileLayout.setVisibility(LinearLayout.INVISIBLE);
        drawerHolder.sectionLayout.setVisibility(LinearLayout.VISIBLE);
        drawerHolder.headerLayout.setVisibility(LinearLayout.INVISIBLE);
        drawerHolder.sectionName.setText(dItem.getSectionName());
    } else {

        drawerHolder.profileLayout.setVisibility(LinearLayout.VISIBLE);
        drawerHolder.sectionLayout.setVisibility(LinearLayout.INVISIBLE);
        drawerHolder.headerLayout.setVisibility(LinearLayout.INVISIBLE);
        try {
            if (userProfile.getString("facebookId") != null) {
                String facebookId = userProfile.get("facebookId")
                        .toString();
                drawerHolder.profilePicture.setProfileId(facebookId);
            } else {
                // Show the default, blank user profile picture
                drawerHolder.profilePicture.setProfileId(null);
            }
            if (userProfile.getString("name") != null) {
                drawerHolder.profileName.setText(userProfile.getString("name"));
            } else {
                drawerHolder.profileName.setText("");
            }
        } catch (JSONException e) {
            Log.d(CarpoolMeApp.TAG,
                    "Error parsing saved user data.");
        }
    }

    return view;
}

Answer 1

您可以手动为headerName和sectionName Textviews

设置高度

    android:layout_height="2dp"

就像你在headerLayout中使用View一样

Answer 2

您可以指定布局重力，这是问题的最可能原因（高度太高）。您也可以使用LinearLayout作为根布局而不是RelativeLayout。如果需要确切的高度，请在 layout_height 参数中指定。
