为什么菜单抽屉上的项目无法点击？ Android导航

标签： java android android-fragments stack-overflow

我的Navigator菜单有一个非常有趣的问题。我不知道为什么......但是我可以点击我菜单中的任何项目，我不想说我点击而没有任何事情发生。我真的想说我不能点击任何项目，我的所有菜单都像一个大图像。我尝试制作一个已经有导航抽屉活动的新项目，当然它可以工作..但是当我尝试复制那些代码然后放上我的...我有同样的问题，反之亦然，我尝试将我的代码放入带有导航抽屉活动的新项目中，但是再次......我无法点击任何项目。

图片 - this trouble

图片 - can't click

这是我的代码：

这个adapter.java 

public class Adapter extends BaseAdapter {
    private Activity activity;
    private LayoutInflater inflater;
    private List<DataModel> item;

    public Adapter(Activity activity, List<DataModel> item) {
        this.activity = activity;
        this.item = item;
    }

    @Override
    public int getCount() {
        return item.size();
    }

    @Override
    public Object getItem(int location) {
        return item.get(location);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        if (inflater == null)
            inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if (convertView == null)
            convertView = inflater.inflate(R.layout.list_buddies, null);

        TextView txt_nama = (TextView) convertView.findViewById(R.id.custom_list_item_text1);

        txt_nama.setText(item.get(position).getNama());

        return convertView;
    }
}

您需要创建此类型的布局xml 

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout"
        android:layout_width="match_parent" android:layout_height="match_parent"
        android:fitsSystemWindows="true" tools:openDrawer="start">

        <FrameLayout
            android:id="@+id/container"
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            xmlns:tools="http://schemas.android.com/tools"
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true">

        </FrameLayout>

         <android.support.design.widget.NavigationView
            android:id="@+id/nav_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:fitsSystemWindows="true"
            app:headerLayout="@layout/nav_header_menu_bar"
            app:menu="@menu/activity_menu_bar_drawer" />

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

在 FrameLayout 中，您需要逐个替换所有片段，如

private void callFragment(Fragment fragment) {
    fragmentManager = getFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.container, fragment)
            .commit();
}

注意：您可以编写协调器布局和其他片段本身，可能对您有所帮助。

其他有类似问题的人。看来XML中的顺序也很重要。

我有了我的NavigationView，之后我有一个布局，我无法点击NavigationView上的一个项目。

在我切换它们之后，我的布局被包含在内，然后我有了我的NavigationView，它有效...
