如何中心对齐低于ImageView的一个TextView作为列表视图标题 [英] How to center align a textview below imageview as a title in a List view

问题描述

我不能够对准下面的ImageView文本在ListView。下面是我的code。

I am not able to align a text below imageview in a listview. below is my code.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center"     >

    <ImageView 
            android:id="@+id/icon"
            android:layout_width="wrap_content"
            android:layout_height="50dp" />


    <TextView 
            android:id="@+id/name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/icon"
            android:layout_alignParentBottom="true"  
            android:gravity="center"
            android:singleLine="true"
            android:layout_marginLeft="20dp"
            android:textColor="@color/white"/>


</RelativeLayout>

和ListView是

and ListView is

<ListView    android:id="@+id/grid_view"
            android:layout_width="wrap_content"
            android:layout_height="280sp"
            android:layout_alignParentLeft="true"
            android:layout_marginTop="20dp"
            android:layout_toLeftOf="@+id/imgView"
            android:scrollbars="none"
            android:divider="@null"
            android:gravity="center" >
</ListView>

Java的code动态添加从阵列文字和图片

java code to dynamically add text and image from array

@Override
    public View getView(int position, View convertView, ViewGroup parent) {         
        ViewHolder holder;
        if (convertView == null) {
            convertView = l_Inflater.inflate(R.layout.gridview_layout, null);
            holder = new ViewHolder();
            holder.imageName = (TextView) convertView.findViewById(R.id.name);
            holder.image = (ImageView) convertView.findViewById(R.id.icon);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }


        holder.imageName.setText(name[position]);
        holder.image.setImageResource(mThumbIds[position]);

        return convertView;
    }

推荐答案

只需使用 layout_centerHorizo​​ntal 在你的TextView属性：

Simply use the layout_centerHorizontal attribute in your TextView:

<TextView
        android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/icon"
        android:layout_alignParentBottom="true"  
        android:layout_centerHorizontal="true"
        android:singleLine="true"
        android:textColor="@color/white" />
