Layout issue on Android with FrameLayout and Scrol

问题:

I'm trying to split the screen in 2 areas, to the left an ImageView and to the right a ScrolView. I'm adding the ImageView and the content of the ScrollView programatically, so the xml file of the layout looks like this:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <FrameLayout
            android:id="@+id/scene_view"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_gravity="left"
            >
    </FrameLayout>
    <ScrollView
            android:layout_height="fill_parent"
            android:layout_width="@dimen/scrollmenu_width"
            android:layout_gravity="right"
            >
        <LinearLayout
                android:id="@+id/scrollmenu"
                android:layout_height="fill_parent"
                android:orientation="vertical"
                android:layout_width="fill_parent"
                >
        </LinearLayout>
    </ScrollView>
</FrameLayout>

What am I doing wrong? because I'm getting the ScrollView to the right, but the ImageView centered (relative to the screen) placed on the left of the screen. The resolution of the image exceeds the screen's resolution so I get black sp

I think you should make use of the LinearLayout and the weight parameter to solve this problem.

I have edited your snippet to give you an idea of how you should use it.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal">

    <FrameLayout
        android:id="@+id/scene_view"
        android:layout_width="0dp"
        android:layout_height="fill_parent"
        android:layout_gravity="left"
        android:layout_weight=1>
    </FrameLayout>
    <ScrollView
        android:layout_height="fill_parent"
        android:layout_width="0dp"
        android:layout_weight=1
        android:layout_gravity="right">
        <LinearLayout
            android:id="@+id/scrollmenu"
            android:layout_height="fill_parent"
            android:orientation="vertical"
            android:layout_width="fill_parent">
        </LinearLayout>
    </ScrollView>
</FrameLayout>

I hope it helps..
