I try to create a Navigation Drawer for all my Activities. I use Android Studio and generate a Navigation Drawer Activity. My other Activities extends in it to get the Navigation Drawer. I insert a Pictue with the Android Studio Feature and now exist the hdpi and xhdpi... in the "mipmap" Folder.
I change in the Navigation Header Layout Background to my inserted Image:
android:background="@mipmap/ic_lmg_bck"
nav_header_nd.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="@dimen/nav_header_height"
android:background="@mipmap/ic_lmg_bck"
android:gravity="bottom"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:theme="@style/ThemeOverlay.AppCompat.Dark">
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="@dimen/nav_header_vertical_spacing"
app:srcCompat="@drawable/ic_launcher" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/nav_header_vertical_spacing"
android:text="Nutzername"
android:textAppearance="@style/TextAppearance.AppCompat.Body1" />
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Nutzernameemail" />
</LinearLayout>
All works but the Image is blurred and to small:

How it is possible to resize the Image ?
