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);
