在xml中使用android:drawableLeft="@drawable/payicon_type";
实现 在控件左侧添加小图标。那么在代码中如何实现同样的效果呢?(上下左右同理)
Drawable drawable = getResources().getDrawable(R.drawable.payicon_type);
/// 这一步必须要做,否则不会显示.
drawable.setBounds(0, 0, drawable.getMinimumWidth(),
drawable.getMinimumHeight());
editview.setCompoundDrawables(drawable,null,null,null);
//另外如果是用assets文件夹下的图片则是
Drawable drawable = FileUtil.getDrawableFromAssetFile(context, "payicon_type.png");
/** * 从assets 文件夹中获取文件并读取图片资源
* @param context
* @param fileName
* @return
*/
public static Drawable getDrawableFromAssetFile(Context context, String fileName) {
BitmapDrawable drawable = null;
try {
InputStream is = context.getAssets().open(fileName);
Bitmap image = BitmapFactory.decodeStream(is);
drawable = new BitmapDrawable(context.getResources(), image);
is.close();
} catch (Exception e) { }
return drawable;
}
