如何设置WearableListView项高度

Question

我制作WearableListView列表.问题是设置android:layout_height ="20dp"没有帮助

在这种情况下如何设置高度？在Android Wear示例项目Notifications and Timer中,他们也只设置了一个android:layout_height ="80dp".但我试图设置项目android:layout_height ="20dp",但它没有帮助!(下面是我的项目源代码):

list_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<base.mobitee.com.mobiteewatch.adapter.HolesListItemLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="20dp"
    android:gravity="center_vertical" >

    <TextView
        android:id="@+id/text_hole"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fontFamily="sans-serif-light"
        android:gravity="center"
        android:textSize="@dimen/list_item_text_size" />
</base.mobitee.com.mobiteewatch.adapter.HolesListItemLayout>

HolesListItemLayout.java:

公共类HolesListItemLayout扩展的LinearLayout实现WearableListView.OnCenterProximityListener {私人TextView的MNAME; private final int mFadedTextColor; private final int mChosenTextColor;

public HolesListItemLayout(Context context) {
    this(context, null);
}

public HolesListItemLayout(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public HolesListItemLayout(Context context, AttributeSet attrs,
                           int defStyle) {
    super(context, attrs, defStyle);
    mFadedTextColor = getResources().getColor(R.color.grey);
    mChosenTextColor = getResources().getColor(R.color.black);
}

// Get references to the icon and text in the item layout definition
@Override
protected void onFinishInflate() {
    super.onFinishInflate();
    mName = (TextView) findViewById(R.id.text_hole);
}

@Override
public void onCenterPosition(boolean animate) {
    mName.setTextSize(18);
    mName.setTextColor(mChosenTextColor);
}

@Override
public void onNonCenterPosition(boolean animate) {
    mName.setTextColor(mFadedTextColor);
    mName.setTextSize(14);
}

}

HolesListAdapter.java:

public class HolesListAdapter extends WearableListView.Adapter {
    private final Context mContext;
    private final LayoutInflater mInflater;

    public HolesListAdapter(Context context) {
        this.mContext = context;
        mInflater = LayoutInflater.from(context);
    }

    @Override
    public WearableListView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new WearableListView.ViewHolder(
                mInflater.inflate(R.layout.list_item_hole, null));
    }

    @Override
    public void onBindViewHolder(WearableListView.ViewHolder holder, int position) {
        TextView text = (TextView) holder.itemView.findViewById(R.id.text_hole);
        text.setText(mContext.getString(R.string.hole_list_item) + " " + (position + 1));
        text.setTextColor(mContext.getResources().getColor(android.R.color.black));
        holder.itemView.setTag(position);
    }

    @Override
    public int getItemCount() {
        return Preferences.HOLES;
    }
}

Answer 1

WearableListView是硬编码的,一次只显示三个项目 - 它通过将列表视图的高度除以3来测量项目高度...因此没有实际的方法来做你想要的.

我建议把文字字体做大......

Answer 2

我有主意了。将列表插入 FrameLayout 容器。并通过更改容器的高度来更改列表项的高度。结果：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="90dp"
        android:layout_centerInParent="true">

        <android.support.wearable.view.WearableListView
            android:id="@+id/wearable_list_game_options"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:dividerHeight="0dp"
            android:scrollbars="none"/>
    </FrameLayout>

</RelativeLayout>
