- Add
CameraView
into your layout xml:
<top.defaults.camera.CameraView
android:id="@+id/preview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
app:mode="video"
app:aspectRatio="4:3"
app:autoFocus="true"
app:facing="back"
app:fillSpace="false"
app:flash="auto"
app:pinchToZoom="false"
app:showFocusIndicator="true"/>
See
top_defaults_camera_attrs.xml
for all supported attributes.
- Create a
Photographer
with theCameraView
:
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// ...
CameraView preview = findViewById(R.id.preview);
photographer = PhotographerFactory.createPhotographerWithCamera2(this, preview);
// ...
}
- Implement and set
Photographer.OnEventListener
to receive events from the camera:
photographer.setOnEventListener(new SimpleOnEventListener() {
@Override
public void onDeviceConfigured() {}
@Override
public void onPreviewStarted() {}
@Override
public void onZoomChanged(float zoom) {}
@Override
public void onPreviewStopped() {}
@Override
public void onStartRecording() {}
@Override
public void onFinishRecording(String filePath) {}
@Override
public void onShotFinished(String filePath) {}
@Override
public void onError(Error error) {}
});
- Start/stop preview in
onResume()
/onPause()
:
@Override
protected void onResume() {
super.onResume();
photographer.startPreview();
}
@Override
protected void onPause() {
photographer.stopPreview();
super.onPause();
}
PhotographerHelper
is your friend:
photographerHelper = new PhotographerHelper(photographer); // init with photographer
photographerHelper.setFileDir(Commons.MEDIA_DIR); // set directory for image/video saving
photographerHelper.flip(); // flip back/front camera
photographerHelper.switchMode(); // switch between image capture/video record
