Android 水平滚动图片库 [英] Android Horizontal scrolling image gallery

问题描述

我想创建具有水平图片库(一行和多列)的应用程序.首先我尝试使用 gridview，但它只能用作垂直滚动.我可以为此目的使用 ListView 或 GridView 吗?

I'd like to create app with horizontal image gallery (with one row and multiple columns). First i try to use gridview, but it can be used as vertical scroll only. Can i use ListView or GridView for that purposes?

推荐答案

在 Horizo​​ntalScrollView 中创建 LinearLayout，然后动态创建一个 imageView 并将该 imageview 添加到 linearLayout.

create LinearLayout inside HorizontalScrollView,then create an imageView dynamically and add that imageview to linearLayout.

示例代码:

<HorizontalScrollView 
android:id="@+id/horizontal_scroll"
android:layout_width="match_parent"
android:layout_height="wrap_content" >

    <LinearLayout
    android:id="@+id/linear"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >
    </LinearLayout>

</HorizontalScrollView>

在onCreate()方法中，从xml文件中获取linearLayout的id，并将动态创建的ImageView添加到linearlayout中:

In onCreate() method,get the id of linearLayout from the xml file and add dynamically created ImageView to linearlayout:

    LinearLayout layout = (LinearLayout) findViewById(R.id.linear);
    for (int i = 0; i < 10; i++) {
        ImageView imageView = new ImageView(this);
        imageView.setId(i);
        imageView.setPadding(2, 2, 2, 2);
        imageView.setImageBitmap(BitmapFactory.decodeResource(
                getResources(), R.drawable.ic_launcher));
        imageView.setScaleType(ScaleType.FIT_XY);
        layout.addView(imageView);
    }
