안드로이드 view -> bitmap 변환

안드로이드 view convert bitmap ll = new FrameLayout(this); iv = new ImageView(this); iv.setImageResource(R.drawable.photo1); iv.setScaleType(ScaleType.FIT_XY); btn = new Button(this); btn.setText("btn"); btn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub bitmap = ll.getDrawingCache();//이게 bitmap으로 만들어준다 mPhotoView.invalidate(); Log.i("aa", "sons bitmap " + bitmap.getWidth() + " height " + bitmap.getHeight()); File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), "aaaa.png"); try { ByteArrayOutputStream byteArray = new ByteArrayOutputStream(); bitmap.compress(CompressFormat.PNG, 100, byteArray); byte[] data = byteArray.toByteArray(); FileOutputStream os = new FileOutputStream(file); os.write(data); os.close(); byteArray.close(); data = null; }catch(Exception e) { Log.i("aa",e.toString()); } } }); ll.addView(iv); ll.addView(btn, new FrameLayout.LayoutParams(android.widget.FrameLayout.LayoutParams.WRAP_CONTENT, android.widget.FrameLayout.LayoutParams.WRAP_CONTENT)); ll.setDrawingCacheEnabled(true);//이부분이 중요 mPhotoView = new PhotoView(this); ll.addView(mPhotoView); setContentView(ll, new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
