This is my layout:
<?xml version="1.0" encoding="UTF-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<SurfaceView android:id="@+id/preview_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerInParent="true"/>
<ViewfinderView
android:id="@+id/viewfinder_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/transparent"/>
<LinearLayout
android:id="@+id/result_view"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/result_view"
android:visibility="gone"
android:padding="4dip">
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView android:id="@+id/App_logo"
android:src="@drawable/mylogo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" />
<TextView android:id="@+id/status_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal"
android:background="@color/transparent"
android:text="@string/msg_default_status"
android:textColor="@color/status_text"
android:textSize="14sp"/>
</LinearLayout>
</FrameLayout>
The problem is that the ImageView
in the bottom of the XML
does not get displayed.
Any ideas?

解决方案
Each of your views contain the properties of "fill_parent" for their layout widths and heights. You need to either specify "wrap_content" for them, or place them in containers with positive and negative margins, or else they will all attempt to take up all of the available space.
其他提示
You should remove android:layout_weight="1" from image view and image will appear.
