在我的应用程序上进行一些修改后，我可以看到它在abdroid工作室模拟器上运行，导航抽屉中的项目都在那里，但是当我在我的手机上安装带有apk的应用程序时，我看不到这些项目但我可以点击。

但我认为错误是在xml文件中，因为我还没有触及java类，但只有xml布局文件才会出现问题：
nav_drawer_row.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true">
<TextView
android:id="@+id/title"
android:layout_width="fill_parent"
android:layout_height="50px"
android:paddingLeft="30dp"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:textSize="15dp"
android:textColor="#ffffff"
android:gravity="center_vertical"
android:textIsSelectable="false" />
</RelativeLayout>
activity_main.xml中：
<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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="@+id/container_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:id="@+id/toolbar"
layout="@layout/toolbar" />
</LinearLayout>
<FrameLayout
android:id="@+id/container_body"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
<fragment
android:id="@+id/fragment_navigation_drawer"
android:name="fr.solutis.solutis.FragmentDrawer"
android:layout_width="@dimen/nav_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
app:layout="@layout/fragment_navigation_drawer"
tools:layout="@layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
这些2 xml的假设是res / layout，但我在res / layout-normal中没有做同样的事情，但我认为这不是问题。
答案 0 :(得分：0)
那是高度，它太小了！所以编辑nav_drawer_row.xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true">
<TextView
android:id="@+id/title"
android:layout_width="fill_parent"
android:layout_height="150px"
android:paddingLeft="30dp"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:textSize="15dp"
android:textColor="#ffffff"
android:gravity="center_vertical"
android:textIsSelectable="false" />
</RelativeLayout>
