我有一个形状，我需要使用以下代码更改颜色：

    @Override
public View getView(int position, View convertView, ViewGroup parent) {
    // Get the data item for this position
    LockListDataModel locks = getItem(position);
    // Check if an existing view is being reused, otherwise inflate the view
    ViewHolder viewHolder; // view lookup cache stored in tag
    if (convertView == null) {
        viewHolder = new ViewHolder();
        LayoutInflater inflater = LayoutInflater.from(getContext());
        convertView = inflater.inflate(R.layout.list_row, parent, false);
        viewHolder.lockName = (TextView) convertView.findViewById(R.id.lockName);
        viewHolder.colour = (ImageView) convertView.findViewById(R.id.list_image);
        convertView.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }// Populate the data into the template view using the data object

    viewHolder.lockName.setText(locks.lockName);
    viewHolder.colour.setVisibility(View.VISIBLE);
    viewHolder.colour.setBackground(ResourcesCompat.getDrawable(getContext().getResources(), R.drawable.time_profile_shape, null));
    LayerDrawable shape = (LayerDrawable) ContextCompat.getDrawable(getContext(),R.drawable.time_profile_shape);
    GradientDrawable color = (GradientDrawable)(shape.findDrawableByLayerId(R.id.time_profile_lock_colour));

    color.setColor(Color.parseColor(locks.color));

    // Return the completed view to render on screen

    return convertView;
}

作为参考，形状如下所示：

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item android:left="2dp" android:top="2dp">
    <shape android:shape="rectangle" android:padding="10dp">
        <solid android:color="@color/colorPrimaryDark"></solid>

        <corners
            android:bottomRightRadius="5dp"
            android:bottomLeftRadius="5dp"
            android:topLeftRadius="5dp"
            android:topRightRadius="5dp"/>
    </shape>
</item>
<item android:right="2dp" android:bottom="2dp" android:id="@+id/time_profile_lock_colour">
    <shape android:shape="rectangle" android:padding="10dp" >
        <solid android:color="@color/backgroundColour"></solid>

        <corners
            android:bottomRightRadius="5dp"
            android:bottomLeftRadius="5dp"
            android:topLeftRadius="5dp"
            android:topRightRadius="5dp"/>
    </shape>
</item>

这是为列表视图填充自定义列表适配器，并且适用于除 21 和 22（棒棒糖）之外的所有 API 级别 18（最低 SDK）+。

API 18 = 工作，颜色变化

API 19 = 工作，颜色变化

API 21 = 颜色不变

API 22 = 颜色不变

API 23 = 工作，颜色变化

我怎样才能让它在棒棒糖上工作？

谢谢
