第一种XML配置

使用layer-list标签

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/t" />

    <item android:drawable="@drawable/tt" />

</layer-list>

然后设置

image.setImageDrawable(getResources().getDrawable(R.layout.layer));

第二种代码生成

Resources r = getResources();

Drawable[] layers = new Drawable[2];

layers[0] = r.getDrawable(R.drawable.t);

layers[1] = r.getDrawable(R.drawable.tt);

LayerDrawable layerDrawable = new LayerDrawable(layers);

testimage.setImageDrawable(layerDrawable);
