在android6.0中,加入了Camera相关新特性,在做开发过程中,遇到闪光灯的操作,如下:
1.导入包: import android.hardware.camera2.CameraManager;
import android.hardware.camera2.CameraAccessException;
2.在onCreate函数中初始化CameraManager:
camerager = (CameraManager)getSystemService(Context.CAMERA_SERVICE);
3.函数:
//flag: true,亮灯 false:灭灯
private void openOrCloseFlashlight(boolean flag){
try{
if(camerager != null){
camerager.setTorchMode("0", flag);//0,指cameraId,通常0代表后置,1代表前置
}
}catch(CameraAccessException ex){
ex.printStackTrace();
}
}
