Android 在SurfaceView的onMeasure（）中，如何计算当前视图的大小

在我的android视频播放器中，如何设置视频的大小，使其适合视图

我已经创建了一个自定义视图。在overriden onMeasure中，我正在考虑计算显示视频的CustomView的大小

然后在setMeasuredDimensionwidth，height；中传递这些尺寸

我没有遇到过任何其他手动设置视频尺寸的方法

谢谢

完美的例子，或者看看这个

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

int desiredWidth = 100;
int desiredHeight = 100;

int widthMode = MeasureSpec.getMode(widthMeasureSpec);
int widthSize = MeasureSpec.getSize(widthMeasureSpec);
int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);

int width;
int height;

//Measure Width
if (widthMode == MeasureSpec.EXACTLY) {
    //Must be this size
    width = widthSize;
} else if (widthMode == MeasureSpec.AT_MOST) {
    //Can't be bigger than...
    width = Math.min(desiredWidth, widthSize);
} else {
    //Be whatever you want
    width = desiredWidth;
}

//Measure Height
if (heightMode == MeasureSpec.EXACTLY) {
    //Must be this size
    height = heightSize;
} else if (heightMode == MeasureSpec.AT_MOST) {
    //Can't be bigger than...
    height = Math.min(desiredHeight, heightSize);
} else {
    //Be whatever you want
    height = desiredHeight;
}

//MUST CALL THIS
setMeasuredDimension(width, height);
}

希望它能有所帮助
