滚动页面与图像/文本/图像

时间：2014-02-05 23:29:22

标签： android eclipse

我是第一个应用程序的新手。我希望页面顶部和底部有一个图像，中间有一大块文本。我希望一切都垂直滚动。无论我尝试什么，当我访问页面时，模拟器都会停止应用程序。

<?xml version="1.0" encoding="utf-8"?>

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

<RelativeLayout 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

<TableLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:stretchColumns="1">

    <TableRow>   
    <ImageView
            android:layout_margin="6dip"
            android:id="@+id/Francis_Top"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:src="@drawable/fhpaint">
    </ImageView>
    </TableRow>

    <TableRow>
    <TextView
            android:id="@+id/help_page_intro"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#FFFFFF"
            android:background="#2E2D2B"
            android:textSize="18sp"
            android:text="@string/francisinfo"
            android:padding="2dip">
    </TextView>
    </TableRow>

    <TableRow>
    <ImageView
            android:layout_margin="6dip"
            android:id="@+id/Francis_Bottom"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:src="@drawable/fhp"> 
    </ImageView>  
    </TableRow>             

</TableLayout>    
</RelativeLayout>          
</Scrollview>

非常感谢任何帮助。

亲切的问候， 伊恩

感谢您快速回复！我希望这个日志有帮助。 伊恩

答案 0 :(得分：0)

首先要做的事情：我认为您可以使用LinearLayout大大简化布局：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <LinearLayout
                  android:orientation="vertical"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scaleType="centerCrop"
            android:src="@drawable/fhpaint"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="16dp"
            android:gravity="center"
            android:text="@string/francisinfo"/>

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scaleType="centerCrop"
            android:src="@drawable/fhp"/>

    </LinearLayout>

</ScrollView>

以下是一个屏幕截图示例：

enter image description here

接下来，您将需要您的视图控制器，在Android世界中称为片段。在其他生命周期方法中，Fragments通常需要覆盖onCreateView（LayoutInflater inflater，ViewGroup容器，Bundle savedInstanceState）以显示其视图。例如：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_layout, container, false);

    ... other code here ...

    return v;
}

一旦你实现了上面的代码，你至少应该看到图像和文本。
