在NavigationDrawer中使用png图标作为drawable

并提前致谢！

我在NavigationDrawer中更改图标时遇到问题，我在NavigationDrawer中使用png图像作为drawable，但它会导致InflaterException。我可以使用png或Android只接受XML drawables吗？

这是错误和代码！任何建议将不胜感激！

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


<group android:checkableBehavior="single">
    <item
        android:id="@+id/nav_cursos"
        android:icon="@drawable/ic_cursos"
        android:title="Cursos" />
    <item
        android:id="@+id/nav_gallery"
        android:icon="@drawable/ic_menu_gallery"
        android:title="Localización" />
    <item

    <item
        android:id="@+id/nav_manage"
        android:icon="@drawable/ic_menu_manage"
        android:title="Tools" />
</group>

<item android:title="Communicate">
    <menu>
        <item
            android:id="@+id/nav_share"
            android:icon="@drawable/ic_menu_share"
            android:title="animaciones" />
        <item
            android:id="@+id/preferencias"
            android:icon="@drawable/ic_menu_send"
            android:title="preferencias" />
    </menu>
</item>


I have tried placing directly image on drawable, and changing drawables.xml too. Here:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
<item name="ic_cursos" type="drawable">@drawable/ic_cursos</item>
<item name="ic_menu_gallery" type="drawable">@android:drawable/ic_menu_gallery</item>
<item name="ic_menu_slideshow" type="drawable">@android:drawable/ic_menu_slideshow</item>
<item name="ic_menu_manage" type="drawable">@android:drawable/ic_menu_manage</item>
<item name="ic_menu_share" type="drawable">@android:drawable/ic_menu_share</item>
<item name="ic_menu_send" type="drawable">@android:drawable/ic_menu_send</item>

但它一直都在失败。这里的错误是：

答案 0 :(得分：0)

Caused by: android.content.res.Resources$NotFoundException: Resource is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f02007f a=2 r=0x7f02007f}
                                                   at android.content.res.Resources.loadDrawable(Resources.java:2068)

该错误表明图像资源可能未放置在可绘制文件夹中。将您的图像放在项目的res / drawable文件夹中。

答案 1 :(得分：0)

Android只能接受导航抽屉菜单的矢量图标。因此，要让您的png图标作为矢量加载，请首先使用https://image.online-convert.com/convert-to-svg之类的工具将其转换为SVG文件。之后，在Android Studio中右键单击您的可绘制文件夹，然后选择“新建”，然后导航到“矢量资产”。在“资产类型”上，选择“本地文件（SVG，PSD）”，然后放置SVG文件的路径并找出其余的文件。我希望这会对某人有所帮助。

答案 2 :(得分：-1)

在导航中使用Drawable的最佳方法是使用以下库... https://github.com/mikepenz/MaterialDrawer 相信我，它会为你节省很多时间。

编辑：这里有一些代码示例如何使用drawable 

public class AdvancedActivity extends AppCompatActivity {
private static final int PROFILE_SETTING = 1;

//save our header or result
private AccountHeader headerResult = null;
private Drawer result = null;

private IProfile profile;
private IProfile profile2;
private IProfile profile3;
private IProfile profile4;
private IProfile profile5;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sample);

    // Handle Toolbar
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle(R.string.drawer_item_advanced_drawer);

    // Create a few sample profile
    profile = new ProfileDrawerItem().withName("Mike Penz").withEmail("mikepenz@gmail.com").withIcon(getResources().getDrawable(R.drawable.profile));
    profile2 = new ProfileDrawerItem().withName("Max Muster").withEmail("max.mustermann@gmail.com").withIcon(getResources().getDrawable(R.drawable.profile2)).withIdentifier(2);
