android 在图库中进行幻灯片播放时图片不会全屏显示

1.在 Slideshowview.java

  

 2.        @Override

         public void apply(GLCanvas canvas) {

             int viewWidth = getWidth();

             int viewHeight = getHeight();

  

             float initScale = Math.min((float)

                     viewWidth / mWidth, (float) viewHeight / mHeight);

             // M: if special SUB_TYPE, 按原始尺寸显示

  

 /**************************************  Edit Start **********************************************/

             if (0 !=(mSubType & MediaObject.SUBTYPE_DRM_NO_RIGHT)) {

 /***************************************Edit End ***********************************************/

  

                 //this logic is familar with that of PositionController.java

                 float minScale = MediatekFeature.getMinimalScale(viewWidth,

                                      viewHeight, mWidth, mHeight, mSubType);

                 float tempScaleLimit = MediatekFeature.minScaleLimit(mSubType);

                 float scaleLimit = tempScaleLimit > 0.0f ? tempScaleLimit : 2.0f;

                 minScale = Math.min(scaleLimit, minScale);

                 initScale = minScale / (1 + SCALE_SPEED);

             }

  

             float scale = initScale * (1 + SCALE_SPEED * mProgress);
