I have been working with the camera2 api demo from google and unfortunately the sample application is built to display the textureview preview at approximately 70% of the screen height, after looking around I was able to determine that this was being caused by the AutoFitTextureView overriding the onMeasure()
method as shown below:
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = MeasureSpec.getSize(heightMeasureSpec);
if (0 == mRatioWidth || 0 == mRatioHeight) {
setMeasuredDimension(width, height);
} else {
if (width < height * mRatioWidth / mRatioHeight) {
setMeasuredDimension(width, width * mRatioHeight / mRatioWidth);
} else {
setMeasuredDimension(height * mRatioWidth / mRatioHeight, height);
}
}
}
I attempted to correct this by setting the correct heights and widths in setMeasuredDimension(width, height);
, this fixed the height issue and gave me a full screen preview from the textureview, however the aspect ratio is completely broken and warped on every device, what is the standard way of fixing this? I see many apps on the play store have found a way to solve this problem but havent been able to track down a fix, any help will go a long way, thanks.
I was able to fix the issue by switching setMeasuredDimension();
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = MeasureSpec.getSize(heightMeasureSpec);
if (0 == mRatioWidth || 0 == mRatioHeight) {
setMeasuredDimension(width, height);
} else {
if (width < height * mRatioWidth / mRatioHeight) {
setMeasuredDimension(height * mRatioWidth / mRatioHeight, height);
} else {
setMeasuredDimension(width, width * mRatioHeight / mRatioWidth);
}
}
