將手勢保存爲位圖

Question

我只想知道我是否可以將手勢作爲位圖從佈局保存爲android。我曾問前一個類似question但從未得到回覆

請幫助...

感謝

Answer 1

我有計劃做相同的，但還沒有付諸實施。我確實注意到，如果像廣告中那樣工作，那麼就有了這個Guesture.toBitmap（）方法，看起來就像是票據。

見http://developer.android.com/reference/android/gesture/Gesture.html#toBitmap%28int,%20int,%20int,%20int,%20int%29

Answer 2

我們可以將手勢保存爲位圖

GestureOverlayView gestureView = (GestureOverlayView) findViewById(R.id.gestures); 
     gestureView.setDrawingCacheEnabled(true); 
     Bitmap bm = Bitmap.createBitmap(gestureView.getDrawingCache()); 
     File f = new File(Environment.getExternalStorageDirectory() 
       + File.separator + "signature.png"); 
     f.createNewFile(); 
     FileOutputStream os = new FileOutputStream(f); 
     os = new FileOutputStream(f); 
     //compress to specified format (PNG), quality - which is ignored for PNG, and out stream 
     bm.compress(Bitmap.CompressFormat.PNG, 100, os); 
     os.close();
