android 的finish()使用问题

Question

本人在做关于安卓拍照的过程中，通过serResult返回一个字符串然后finish(),当程序第一次
调用的时候，可以正常返回，但是当再次启动拍照之后，返回的时候finish没有执行onpause()
方法。是通过CameraSurfaceView 的方式进行预览，但是没有回调SurfaceHolder.Callback 中的
surfaceDestroyed()方法。两次执行前日志一样，但是两次调用到setResult()之后就不一样了。日志是：

@Override

        TessEngine tessEngine = new TessEngine(this);
        String text = tessEngine.detectText(bitmap);
        Intent intent = new Intent();
        intent.putExtra("recognize_back", text);

Answer 3

第二次的log贴完了吗？个人感觉应该是生命周期的问题，把生命周期的log都打出来分析一下应该不难明白

Answer 4

第二次log已经全部贴出来了，onPause()方法都没有执行到

Answer 5

把onActivityResult的代码贴上来看看

Answer 6

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            switch (requestCode) {
                case AppStaticData.CAMERA_RESULT_CODE:
                    if (data != null) {
                        String recognizeBack = data.getStringExtra("recognize_back");
                        Log.i(AppStaticData.TAG,"识别的结果是："+recognizeBack);
                        recognizePicCallback(recognizeBack);
                    }
                    break;
                default:                    break;
            }
        }
    }
