setColorFilter不会对Android和LT工作; 2.2 [英] setColorFilter doesn't work on Android < 2.2

问题描述

我有一个绘制的setColorFilter法的一个问题。

i have a problem with the setColorFilter-Method on a drawable.

它正常工作在Android 2.2，但不低于版本。

It works fine on Android 2.2 but not on a version lower than that.

我的问题是类似于这里<一个描述是什么href=\"http://stackoverflow.com/questions/5499637/drawable-setcolorfilter-not-working-on-android-2-1\">Drawable.setColorFilter()不工作在Android 2.1 的，但是，这并不为我工作...

My problem is similar to what is described here Drawable.setColorFilter() not working on Android 2.1, but that doesn't work for me...

我用这个code这在Android 2.2，但没有任何东西低于正常工作。

I use this code which works fine on Android 2.2 but not on anything lower than that.

ImageView imageView = (ImageView) findViewById( R.id.imageView1 );        
Bitmap immutableBitmap = BitmapFactory.decodeResource( getResources(), R.drawable.mybitmap );
Bitmap mutableBitmap = immutableBitmap.copy( Bitmap.Config.ARGB_8888, true );
immutableBitmap.recycle();
immutableBitmap = null;
Drawable d1 = new BitmapDrawable( mutableBitmap );
d1.setColorFilter( 0xff00ffff, PorterDuff.Mode.MULTIPLY );
imageView.setImageDrawable( d1 );

任何线索得到它的工作是多AP preciated：）

Any clues to get it working are much appreciated :)

推荐答案

我不知道是否有解决这个另一种方式，但我发现，使用 imageView.setBackgroundDrawable（）而不是 imageView.setImageDrawable（）解析针对＆lt这一问题; 2.2。

I don't know if there's another way around this, but i found that using imageView.setBackgroundDrawable() instead of imageView.setImageDrawable() resolves this issue on < 2.2.
