What is wrong with this layout? Android_问答_开发者

I am trying to accomplish a view like this: left side = live camera preview, right side = a column of 4 images. But all that I managed with the following xml was a fullscreen live camera preview. Android 1.5 emulator.

Thanks

        android:id="@+id/preview"

        android:layout_width="wrap_content" 
        android:layout_alignParentLeft="true"
        android:layout_weight="3"/>

Vishwanath,

I have adjusted your layout like this

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

    <LinearLayout
        android:layout_height="fill_parent" 
        android:layout_width="wrap_content" 
        android:layout_alignParentLeft="true"
        android:layout_weight="3">

        <proto.wiinkme.SurfaceViewEx 
            android:id="@+id/preview" 
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"/>

    </LinearLayout>

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_toRightOf="@+id/preview"
        android:layout_alignParentRight="true"
        android:layout_weight="2">

        <ImageView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/mother_earth"
            android:src="@drawable/mother_earth_show" />

        <ImageView
            android:layout_below = "@+id/mother_earth"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/meadow"
            android:src="@drawable/meadow_show" />

        <ImageView
            android:layout_below = "@+id/meadow"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/trap"
            android:src="@drawable/trap_show" />

        <ImageView
            android:layout_below = "@+id/trap"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/whistle"
            android:src="@drawable/whistle_show" />

        <Button
            android:layout_below = "@+id/whistle"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/reset"
            android:text="Reset" />

        <Button
            android:layout_below = "@+id/reset"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/save"
            android:text="Save" />


    </RelativeLayout>

</RelativeLayout>

And had some rather strange effects.

Checkout the below one... It works as per your requirement.....

Replace the Linear Layout with yours....

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

    <LinearLayout
        android:id="@+id/preview" 
        android:layout_height="fill_parent" 
        android:layout_width="wrap_content" 
        android:layout_alignParentLeft="true"
        android:layout_weight="3">
        <ImageView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:src="@drawable/icon" />
    </LinearLayout>

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_toRightOf="@+id/preview"
        android:layout_alignParentRight="true"
        android:layout_weight="2">

        <ImageView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/mother_earth"
            android:src="@drawable/icon" />

        <ImageView
            android:layout_below = "@+id/mother_earth"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/meadow"
            android:src="@drawable/icon" />

        <ImageView
            android:layout_below = "@+id/meadow"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/trap"
            android:src="@drawable/icon" />

        <ImageView
            android:layout_below = "@+id/trap"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/whistle"
            android:src="@drawable/icon" />


    </RelativeLayout>

</RelativeLayout>

This is how I have worked around it, but it is still wrong, as it can be seen, I have hardcoded the dimensions of my elements in 'dips'. Probably fine for pre 1.6 but in post 1.6 incuding 1.6 version of Android this layout will break for other screens than 320 x 480 3.2 inches.
