試圖有一個水平滾動視圖動態圖片

Question

我想使用排氣，可以拉入儘可能多的圖像，然後在水平滾動視圖中設置它們的Android應用程序。到目前爲止，我讓他們進來，但不管我做什麼，都不會讓我滾動它。

XML

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal" 
    android:id="@+id/containerLayout" > 

    <HorizontalScrollView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_below="@+id/textView1" 
     android:id="@+id/scrollLayout"> 

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


      <ImageView 
       android:id="@+id/niv_large" 
       android:layout_width="match_parent"

     </LinearLayout>

的Java文件

public class AppActivity extends Activity

    private RequestQueue mRequestQueue;

    Button button;

    <HorizontalScrollView

     android:layout_below="@+id/textView1" 
     android:id="@+id/scrollLayout">

    </HorizontalScrollView> 

</RelativeLayout> 

使用XML和添加所有圖像具有ID容器佈局 「containerLayout」 的setContentView（main.xml中）會工作。

Answer 2

顯然，您不會使用XML佈局文件，因爲您從不加載它。您提供自己的LinearLayout，而不是提供XML佈局。這就是爲什麼你不能滾動。

1. 使用XML佈局時，請取出的LinearLayout實例化，並從中R.id.myContainer
2. 參考與setContentView(R.layout.your_xml);

更換setContentView(containerLayout, lParams);您不必包括參數文件。

解決辦法：

XML

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal" 
    android:id="@+id/containerLayout" > 

    <HorizontalScrollView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_below="@+id/textView1" 
     android:id="@+id/scrollLayout"> 

     <LinearLayout 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:orientation="horizontal" 
      android:id="@+id/myContainer" /> 

    </HorizontalScrollView> 

</RelativeLayout>
