Question

我想创建带有水平图库的应用程序（包含一行和多列）。首先我尝试使用gridview，但它只能用作垂直滚动。我可以将ListView或GridView用于此目的吗？

Image gallery with horizontal scrolling

Answer 1

在HorizontalScrollView中创建LinearLayout，然后动态创建一个imageView并将该imageview添加到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：

    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);
    }

随着RecyclerView库的发布，您可以轻松实现水平和垂直列表方向。这可以通过使用LinearLayoutManager来实现，您可以为其指定水平或垂直方向，如下所示......

 LinearLayoutManager horizontalLayoutManager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.HORIZONTAL, false);

使用HorizontalScrollView而不是ListView或GirdView http://developer.android.com/reference/android/widget/HorizontalScrollView.html

TwoWayView对我有用。 https://github.com/lucasr/twoway-view/

Answer 5

HorizontalScrollView Documentation

要使用HorizontalScrollView，您应该只有一个孩子。我之前使用它的方式与你正在做的图像是通过创建一个TableLayout并将图像添加到TableRows。 TableLayout可以有很多行，也可以只有1行和多列。

您可以将ImageViews（或任何其他视图）添加到每一行，然后最终将TableRow添加到TableLayout。完成TableLayout之后，您需要做的就是：

    //createTable method is where you would loop through the images to add
    TableLayout table = createTable(rowCount, columnCount);
    HorizontalScrollView hozView = new HorizontalScrollView(this);
    hozView.addView(table);
    setContentView(hozView);

由于我们no longer have Gallery小部件需要一些DIY nouse。您可以使用HorizontalScrollView和嵌套LinearLayout创建水平滚动缩略图条，并在活动中动态添加图像：

<HorizontalScrollView
    android:layout_width="match_parent"
    android:layout_height="72dp"
    android:layout_gravity="bottom"
    android:background="@color/black">
    <LinearLayout
        android:id="@+id/thumbnails"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:gravity="center_vertical"
        android:orientation="horizontal"
        android:paddingTop="2dp"/>
</HorizontalScrollView>

您可以使用Recycler View创建幻灯片图像视图

layoutManager=new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL, false);
                    Hor_RecylerView.setLayoutManager(layoutManager);
                    AlphaInAnimationAdapter alphaAdapter = new AlphaInAnimationAdapter(i);
                    Hor_RecylerView.getItemAnimator().setAddDuration(1000);
                    Hor_RecylerView.setAdapter(new SlideInLeftAnimationAdapter(alphaAdapter));
