Question

我有一个动态网格视图。意味着其内容各不相同因此，如果项目数量增加，则会进行垂直滚动。我想把它作为水平滚动。

请为此提出一些解决方案。

Answer 1

        <HorizontalScrollView
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/seatLegendLayout">

        <FrameLayout
            android:layout_width="fill_parent"
            android:layout_height="match_parent">

            <LinearLayout
                android:id="@+id/linearLayout_gridtableLayout"
                android:layout_width="900dp"
                android:layout_height="match_parent"
                android:orientation="horizontal">

                <GridView
                    android:id="@+id/gridView1"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:layout_margin="4dp"
                    android:columnWidth="100dp"
                    android:gravity="center"
                    android:numColumns="9"
                    android:horizontalSpacing="1dp"
                    android:scrollbarAlwaysDrawHorizontalTrack="true"
                    android:scrollbarAlwaysDrawVerticalTrack="true"
                    android:scrollbars="horizontal"
                    android:stretchMode="none"
                    android:verticalSpacing="1dp">

                </GridView>


            </LinearLayout>
        </FrameLayout>
    </HorizontalScrollView>

Answer 2

您可以使用第三方库two-way grid view。它非常适合水平滚动，或者您可以使用RecyclerView

Answer 3

您可以尝试将GridView放入HorizontalScrollView。您可以尝试将固定高度设置为GridView内的HorizontalScrollView。

然后，您可以根据您的内容动态计算GridView的列数，并使用setNumColumns(int)方法进行设置。

你可以使用我的逻辑来看看：

以下是一些解决方案（已更新）：

将此信息包含在您的活动xml：

中

<HorizontalScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scrollbars="none"
    android:id="@+id/title_horizontalScrollView"
    android:layout_margin="1dp"
    android:fillViewport="false">

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

        <GridView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/horizontal_gridView"
            android:layout_gravity="center"/>
    </LinearLayout>
</HorizontalScrollView>

在布局文件夹中创建自定义网格项：

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

<TextView
    android:id="@+id/grid_item"
    android:layout_width="120dp"
    android:layout_height="30dp"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:gravity="center"
    android:text="here is the text"
    android:textAlignment="center"
    android:textSize="15sp"
    android:textStyle="bold" />
</RelativeLayout>

你需要从代码中配置它（因为这是更好的方法）并且还可以通过适配器感受它：

public class MainActivity extends AppCompatActivity {

public GridView gridView;

String[] models = {"Some text here", "and here" ,"and also here","one here","hello","here too"," and here"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    gridView = (GridView)findViewById(R.id.horizontal_gridView);
    gridViewSetting();
}


private void gridViewSetting() {

    // this is size of your list with data
    int size = models.length;
    // Calculated single Item Layout Width for each grid element .. for me it was ~100dp
    int width = 100 ;

    // than just calculate sizes for layout params and use it
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics(dm);
    float density = dm.density;

    int totalWidth = (int) (width * size * density);
    int singleItemWidth = (int) (width * density);

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            totalWidth, LinearLayout.LayoutParams.MATCH_PARENT);

    gridView.setLayoutParams(params);
    gridView.setColumnWidth(singleItemWidth);
    gridView.setHorizontalSpacing(2);
    gridView.setStretchMode(GridView.STRETCH_SPACING);
    gridView.setNumColumns(size);
    GridAdapter adapter = new GridAdapter(MainActivity.this, models);
    gridView.setAdapter(adapter);

} }

这是自定义适配器的示例：

public class GridAdapter extends BaseAdapter {

private String[] modelsName;

private Context context;

private LayoutInflater inflater;

public GridAdapter(Context con, String[] names) {
    this.modelsName = names;
    this.context = con;
}

@Override
public int getCount() {
    return modelsName.length;
}

@Override
public Object getItem(int i) {
    return modelsName[i];
}

@Override
public long getItemId(int i) {
    return i;
}

@Override
public View getView(int i, View view, ViewGroup viewGroup) {

    View gridView = view;

    if(view == null) {
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        gridView = inflater.inflate(R.layout.custom_layout, null);
    }

    TextView text = (TextView) gridView.findViewById(R.id.grid_item);

    text.setText(modelsName[i]);

    return gridView;
} }
