用layer-list一次加载多个层次图片

layer.xml

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/user_faceback_drawable" android:drawable="@drawable/faceback" />
    <item android:id="@+id/user_face_drawable" android:drawable="@drawable/h001"
        android:left="10.0dip" android:top="18.0dip" android:right="25.0dip"
        android:bottom="35.0dip" />
</layer-list>

 

就是把drawable文件夹下的image图片faceback和h001多层叠加来组成新图片。

上面的xml可以这样引用：

1.在其它xml布局里引用：

<ImageView android:id="@+id/faceImg" android:background="@drawable/layer"
                android:layout_width="wrap_content" android:layout_height="wrap_content" />

 

2.在代码里引用：

((ImageView) findViewById(R.id.imageview)).setImageDrawable(getResources().getDrawable(R.drawable.layer));

 

Resources r = getResources();
     Drawable[] layers = new Drawable[2];
     layers[0] = r.getDrawable(R.drawable.cor_info);
     layers[1] = r.getDrawable(R.drawable.icon);
     LayerDrawable layerDrawable = new LayerDrawable(layers);

     ((ImageView) findViewById(R.id.imageview)).setImageDrawable(layerDrawable);
