android: How to check flash if on/off/auto?

Question

So I'm trying to have a button where users can choose between flash on/off/auto. This button is within my camera preview activity, but I'm not sure how to check certain parameters with one button. ``` //Flash Button final Button flashButton = (Button) findViewById(id.camera_flash); flashButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub if(mCamera != null){ Parameters p = mCamera.getParameters(); p.setFlashMode(Parameters.FLASH_MODE_AUTO); mCamera.setParameters(p); mCamera.startPreview(); flashButton.setText("AUTO"); Log.e("Torch","Torch On"); }else{ Parameters p = mCamera.getParameters(); p.setFlashMode(Parameters.FLASH_MODE_OFF); mCamera.setParameters(p); mCamera.release(); mCamera=null; flashButton.setText("OFF"); }// maybe another one for ON } ``` Right now its setting if `mCamera!=null` but then how do I check if flash is AUTO, ON, or OFF? I'm thinking that there maybe a SWITCH instead? I'm trying to k…

Accepted Answer

You can check if flash is AUTO, ON, or OFF as:

```
Camera.Parameters p= mCamera.getParameters();

if(p.getFlashMode().equals(android.hardware.Camera.Parameters.FLASH_MODE_ON))
{
 //DO STUFF...
}
else if(p.getFlashMode().equals(android.hardware.Camera.Parameters.FLASH_MODE_OFF))
{
//DO STUFF......
}
else if(p.getFlashMode().equals(android.hardware.Camera.Parameters.FLASH_MODE_TORCH))
{
//DO STUFF......
}
else if(p.getFlashMode().equals(android.hardware.Camera.Parameters.FLASH_MODE_AUTO))
{
//DO STUFF......
}
else
{
//DO STUFF.....
}
```
