Fotoapparat

讓 Camera 的 API?更簡單，支持 Camera1 和 Camera2 。

讓拍照變得更簡單：

Fotoapparat?fotoapparat?=?Fotoapparat
????.with(context)??
????.into(cameraView)
????.build();

fotoapparat.start();
????
fotoapparat
????.takePicture()
????.saveToFile(someFile);

如何運(yùn)行

第一步：將 CameraView 添加到布局

第二步：配置 Fotoapparat 實(shí)例

Fotoapparat
????.with(context)??
????.into(cameraView)???????????//?view?which?will?draw?the?camera?preview
????.photoSize(biggestSize())???//?we?want?to?have?the?biggest?photo?possible
????.lensPosition(back())???????//?we?want?back?camera
????.focusMode(firstAvailable(??//?(optional)?use?the?first?focus?mode?which?is?supported?by?device
????????????continuousFocus(),
????????????autoFocus(),????????//?in?case?if?continuous?focus?is?not?available?on?device,?auto?focus?will?be?used
????????????fixed()?????????????//?if?even?auto?focus?is?not?available?-?fixed?focus?mode?will?be?used
????))
????.flash(firstAvailable(??????//?(optional)?similar?to?how?it?is?done?for?focus?mode,?this?time?for?flash
????????????autoRedEye(),
????????????autoFlash(),
????????????torch()
????))
????.frameProcessor(myFrameProcessor)???//?(optional)?receives?each?frame?from?preview?stream
????.logger(loggers(????????????//?(optional)?we?want?to?log?camera?events?in?2?places?at?once
????????????logcat(),???????????//?...?in?logcat
????????????fileLogger(this)????//?...?and?to?file
????))
????.build();

第三步：調(diào)用 start（）和 stop（）

@Override
protected?void?onStart()?{
????super.onStart();
????fotoapparat.start();
}

@Override
protected?void?onStop()?{
????super.onStop();
????fotoapparat.stop();
}

然后，拍照吧！你有多項(xiàng)選擇：

PhotoResult?photoResult?=?fotoapparat.takePicture();
?
//?Asynchronously?saves?photo?to?file
photoResult.saveToFile(someFile);
?
//?Asynchronously?converts?photo?to?bitmap?and?returns?result?on?main?thread
photoResult
????.toBitmap()
????.whenAvailable(new?PendingResult.Callback()?{
????????@Override
????????public?void?onResult(BitmapPhoto?result)?{
????????????ImageView?imageView?=?(ImageView)?findViewById(R.id.result);

????????????imageView.setImageBitmap(result.bitmap);
????????????imageView.setRotation(-result.rotationDegrees);
????????}
????});
????
//?Of?course?you?can?also?get?a?photo?in?a?blocking?way.?Do?not?do?it?on?main?thread?though.
BitmapPhoto?result?=?photoResult.toBitmap().await();
?
//?Convert?asynchronous?events?to?RxJava?1.x/2.x?types.?See?/fotoapparat-adapters/?module
photoResult
????????.toBitmap()
????????.adapt(SingleAdapter.toSingle())
????????.subscribe(bitmapPhoto?->?{
????????????
????????});
