在 Android Lollipop 版本上关闭手电筒
Turn off Flashlight on Android Lollipop version
kCamera = Camera.open();
kCamera.Parameters cam1= k.Camera.getParameters();
cam1.setFlashMode(Parameters.FLASH_MODE_TORCH);
kCamera.setParameters(cam1);
SurfaceTexture mPreviewTexture = new SurfaceTexture(0);
try {
kCamera.setPreviewTexture(mPreviewTexture);
} catch {
}
mCam.startPreview();
这很好用,它打开了手电筒。
但是我怎样才能关闭呢?
public static final String FLASH_MODE_OFF
Added in API level 5 Flash will not be fired.
Constant Value: "off"
所以,你可以这样定义函数:
public void turnOffFlashLight(Camera camera){
Camera.Parameters cam1 = camera.getParameters();
cam1.setFlashMode(Camera.Parameters.FLASH_MODE_OFF);
kCamera.setParameters(cam1);
}
然后,在需要的时候使用它:
turnOffFlashLight(kCamera);
kCamera = Camera.open();
kCamera.Parameters cam1= k.Camera.getParameters();
cam1.setFlashMode(Parameters.FLASH_MODE_TORCH);
kCamera.setParameters(cam1);
SurfaceTexture mPreviewTexture = new SurfaceTexture(0);
try {
kCamera.setPreviewTexture(mPreviewTexture);
} catch {
}
mCam.startPreview();
