手电筒不FLASH_MODE_TORCH [英] Flashlight without FLASH_MODE_TORCH

问题描述

是否有开启闪光灯上的不确定时间的时候，手机心不是支持FLASH_MODE_TORCH在Camera.Parameters任何选项？

Is there any options for turning the flash light on for undefined time when the phone isnt supporting the FLASH_MODE_TORCH in Camera.Parameters ?

我知道这是可能becouse有很多工作在我的手机（三星Galaxy ACE）的应用程序，但我不找到答案。

I know it is possible becouse there are many of apps working on my phone (Samsung Galaxy ACE) but I dont find the answer yet.

我只是来：

Camera camera = Camera.open();
Camera.Parameters params = camera.getParameters();
params.setFlashMode(Camera.Parameters.FLASH_MODE_ON) //because FLASH_MODE_TORCH isnt supported
camera.setParameters(params);
camera.startPreview();
camera.autoFocus(new AutoFocusCallback(){
public void onAutoFocus(boolean success, Camera camera){
camera.autoFocus(this);
}
});

不过这正与小的延迟像1/10秒。

but this is working with little delay like 1/10 of second.

谁？

推荐答案

可能延迟来自自动对焦。你有没有尝试设置焦点到无限远？

May be delay comes from autofocus. Did you tried to set focus to infinity ?

params.setFocusMode(Camera.Parameters.FOCUS_MODE_INFINITY);
