我還是新來的這裏在Android。請幫幫我。我設法將imageview放在我的Layout的左側和右側。我的問題是，當我爲imageview2選擇圖像時，它會將圖像傳遞給imageview1，並且仍然可以從右側看到imageview2。選擇imageview1在左側和imageview2在右側固定
我需要做的是當我爲imageview2選擇圖像時，它應該固定在右側。我認爲我在java中的代碼有問題？
這裏是我的代碼爲xml。
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/insert_bg"
>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="15dip"
android:paddingBottom="15dip"
>
<ImageView
android:id="@+id/img_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fitsSystemWindows="false"
android:scaleType="fitStart"
android:src="@drawable/insert_ci" />
<ImageView
android:id="@+id/img_center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="2"
android:fitsSystemWindows="false"
android:scaleType="fitEnd"
android:src="@drawable/insert_ci"
android:textAlignment="viewEnd" />
</LinearLayout>
而這種代碼的Java。

我說的問題就是這樣。 http://imageshack.us/photo/my-images/31/6sa6.png/
它仍然是這樣的。當我爲imageview2選擇圖像時，它傳遞給imageview1或類似的東西。 – Suprance
