修改Android系統 滑鼠游標 (續)

     今天我轉了一篇文章關於修改android滑鼠游標的表徵圖.文章講的是系統中通過描點的方式得到一個簡單的游標映像.下面我要講的是如何直接畫一個圖片上去.

     直接上代碼,代碼的位置與上一篇文章一致,不瞭解的可以去看一下先.

               if (mMouseSurface == null)

                {
                       int mMx, mMy, mMw, mMh;
                       Canvas mCanvas;
                       Path mPath = new Path();
                       Bitmap bitmap = BitmapFactory.decodeResource(mContext.getResources(), com.android.internal.R.drawable.mouse_cursor);
               
                       mMw = bitmap.getWidth() + 5;
                       mMh = bitmap.getHeight() + 5;
                       Log.i(TAG, "Width of mouse icon is " + mMw + ", height is " + mMh);
                       mMx = (mDisplay.getWidth() - mMw) / 2;
                       mMy = (mDisplay.getHeight() - mMh) / 2;
                       try {
                       mMouseSurface =
                               new Surface(mFxSession,0,-1,mMw,mMh,
                               PixelFormat.TRANSPARENT,Surface.FX_SURFACE_NORMAL);
                       mCanvas = mMouseSurface.lockCanvas(null);
                       mCanvas.drawColor(0x0);
        
                       mCanvas.drawBitmap(bitmap, 0, 0, null);
                   
                       mMouseSurface.unlockCanvasAndPost(mCanvas);
                       mMouseSurface.setSize(mMw,mMh);
                        mMouseSurface.hide();
                        mShowMouse = false;
                       } catch (Exception e) {
                       Log.e(TAG, "Exception creating mouse surface",e);
                               }
                       mMlx = mMx;
                       mMly = mMy;
                       mMlw = mMw;
                               mMlh = mMh;
                       }

                  不做過多的解釋.可自行理解,
