這就是我要的

Answer 1

在XML中添加另一個視圖，並將其放置在DrawerLayout activity_main_drawer DrawerLayout 。 標頭可能不應該滾動，因此不應在列表視圖中。 另外，從列表視圖項目布局中刪除drawer_image 。 由於不應將其包含在所有項目中。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <include layout="@layout/toolbar" />

    <android.support.v4.widget.DrawerLayout
        android:id="@+id/activity_main_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <FrameLayout
            android:id="@+id/activity_main_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

        </FrameLayout>

        <LinearLayout
            android:layout_width="@dimen/drawer_width"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:orientation="vertical">
            <ImageView
                android:id="@+id/drawer_image"
                android:layout_width="280dp"
                android:layout_height="140dp"
                android:src="@drawable/loading" />
            <ListView
                android:id="@+id/activity_main_drawer"
                android:layout_height="match_parent"
                android:layout_width="match_parent"
                android:choiceMode="singleChoice"
                android:drawSelectorOnTop="true"
                android:fastScrollEnabled="false"
                android:listSelector="@drawable/selector_clickable_item_bg"
                android:background="@color/global_bg_front"
                />
        </LinearLayout>

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

</LinearLayout>

或使用http://developer.android.com/reference/android/support/design/widget/NavigationView.html並將您的圖像添加為標題視圖。

navView = (NavigationView) findViewById(R.id.navView);
navView.inflateHeaderView(R.layout.myheader)

或XML

app:headerLayout="@layout/myheader"

Answer 2

嘗試通過將標題視圖添加到列表視圖中（在這種情況下標題也會滾動），您需要在MainActivity中執行以下操作：

View header = (View) getLayoutInflater().inflate(
            R.layout.header_layout, null);
ImageView img=(ImageView)header.findViewById(R.id.imgView);
img.setBackgroundResource(R.drawable.icon);
mainListView.addHeaderView(header);

或者，您可以像這里或這里一樣使用DesignLibrary。
