Android布局覆盖问题

Question

android布局

Answer 1

你这是线型布局 如果控件过大 会把其他按钮挤到下面去，可以用ScrollView套一层。

<ScrollView>
   <LinearLayout>  </LinearLayout></ScrollView>

Answer 3

用相对布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >    <LinearLayout
        android:id="@+id/linearLayout_1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:orientation="vertical" >        <EditText
            android:layout_width="200dp"
            android:layout_height="35dp"
            android:layout_gravity="center"
            android:autoLink="web"
            android:hint="输入要查找的商品" />        <android.support.v4.view.ViewPager
            android:id="@+id/adv_pager"
            android:layout_width="fill_parent"
            android:layout_height="70dp" >
        </android.support.v4.view.ViewPager>        <LinearLayout
            android:id="@+id/viewGroup"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/adv_pager"
            android:layout_marginTop="-25px"
            android:gravity="right"
            android:orientation="horizontal" >            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="left"
                android:layout_marginTop="5dp"
                android:text="品种分类" />            <GridView
                android:id="@+id/gridview1"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:numColumns="2" >
            </GridView>
        </LinearLayout>
    </LinearLayout>    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/relativeLayout21"
        android:layout_gravity="bottom" >        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:text="首页" />        <Button
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_toRightOf="@+id/button1"
            android:text="搜索" />        <Button
            android:id="@+id/button3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_toRightOf="@+id/button2"
            android:text="我的" />        <Button
            android:id="@+id/button4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_toRightOf="@+id/button3"
            android:text="更多" />
    </RelativeLayout>    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@id/relativeLayout21"
        android:layout_below="@id/linearLayout_1"
        android:background="@drawable/logo" />
</RelativeLayout>先把固定的位置布局好，中间的imageview再布局到顶部和底部中间去
