Android LayerDrawable：如何以编程方式设置图层坐标？

Question

The following XML code of a layer-list ist given:

<layer-list>
    <item>
        <shape android:shape="rectangle" >
            <solid android:color="@color/my_color_a" />
        </shape>
    </item>
    <item android:left="5dp">
        <shape android:shape="rectangle" >
            <solid android:color="@color/my_color_b" />
        </shape>
    </item>
</layer-list>

To do some things dynamically I need to rebuild this code programmatically as a LayerDrawable class. This code exists:

ShapeDrawable layer0 = new ShapeDrawable(new RectShape());
ShapeDrawable layer1 = new ShapeDrawable(new RectShape());
LayerDrawable layerDrawable = new LayerDrawable(new Drawable[] {layer0, layer1});

How do you translate android:left="5dp" to Java code? There is no setter for this property.

Answer 1

Try setLayerInset(layer, leftOffset, topOffset, rightOffset, bottomOffset)

Refer to the LayerDrawable documentation for more help.
