我正在调用相机 Intent 并在 onActivityResult() 中处理位图。我正在通过工作正常的 NDK 处理图像。然后我想打开一个对话框来显示图像，但没有任何反应。

   private void startIrisRoutine(Bitmap imageBitmap) {
    File tempDir = new File(getFilesDir() + File.separator + Constants.DIR_TEMP);
    tempDir.mkdirs();

    // create file for taken photo
    final File inputFile = new File(tempDir + File.separator + Constants.FILE_INPUT + Constants.END_JPG);

    // create face part files in temp folder
    final File facePartFace = new File(tempDir + File.separator + Constants.FILE_FACE + Constants.END_PNG);
    final File facePartEyeRight = new File(tempDir + File.separator + Constants.FILE_EYE_RIGHT + Constants.END_PNG);
    final File facePartEyeLeft = new File(tempDir + File.separator + Constants.FILE_EYE_LEFT + Constants.END_PNG);

    //create texture files
    final File textureWahetRightFile = new File(tempDir + File.separator + Constants.FILE_TEXTURE + USITHelper.ALGO_SEG_WAHET_SHORT + Constants.FILE_EYE_RIGHT + Constants.END_PNG);
    final File textureCahtRightFile = new File(tempDir + File.separator + Constants.FILE_TEXTURE + USITHelper.ALGO_SEG_CAHT_SHORT + Constants.FILE_EYE_RIGHT + Constants.END_PNG);
    final File textureWahetLeftFile = new File(tempDir + File.separator + Constants.FILE_TEXTURE + USITHelper.ALGO_SEG_WAHET_SHORT + Constants.FILE_EYE_LEFT + Constants.END_PNG);
    final File textureCahtLeftFile = new File(tempDir + File.separator + Constants.FILE_TEXTURE + USITHelper.ALGO_SEG_CAHT_SHORT + Constants.FILE_EYE_LEFT + Constants.END_PNG);

    // create temp segmentation files
    final File segmentationWahetRightFile = new File(tempDir + File.separator + Constants.FILE_SEGMENTS + USITHelper.ALGO_SEG_WAHET_SHORT + Constants.FILE_EYE_RIGHT + Constants.END_JPG);
    final File segmentationCahtRightFile = new File(tempDir + File.separator + Constants.FILE_SEGMENTS + USITHelper.ALGO_SEG_CAHT_SHORT + Constants.FILE_EYE_RIGHT + Constants.END_JPG);
    final File segmentationWahetLeftFile = new File(tempDir + File.separator + Constants.FILE_SEGMENTS + USITHelper.ALGO_SEG_WAHET_SHORT + Constants.FILE_EYE_LEFT + Constants.END_JPG);
    final File segmentationCahtLeftFile = new File(tempDir + File.separator + Constants.FILE_SEGMENTS + USITHelper.ALGO_SEG_CAHT_SHORT + Constants.FILE_EYE_LEFT + Constants.END_JPG);

    try {
        FileOutputStream fos = new FileOutputStream(inputFile);
        imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    mUSITHelper.findFaceParts(inputFile, facePartFace, facePartEyeLeft, facePartEyeRight);

    mUSITHelper.segmentPicture(facePartEyeLeft, textureWahetLeftFile, segmentationWahetLeftFile, USITHelper.ALGO_SEG_WAHET);
    mUSITHelper.segmentPicture(facePartEyeLeft, textureCahtLeftFile, segmentationCahtLeftFile, USITHelper.ALGO_SEG_CAHT);
    mUSITHelper.segmentPicture(facePartEyeRight, textureWahetRightFile, segmentationWahetRightFile, USITHelper.ALGO_SEG_WAHET);
    mUSITHelper.segmentPicture(facePartEyeRight, textureCahtRightFile, segmentationCahtRightFile, USITHelper.ALGO_SEG_CAHT);

    final AlertDialog.Builder alertadd = new AlertDialog.Builder(this);
    alertadd.setCancelable(false);
    LayoutInflater factory = LayoutInflater.from(this);
    View view = factory.inflate(R.layout.dialog_segmen, null);

    alertadd.setTitle("Only select properly segmented pictures:");

    alertadd.setView(view);
    alertadd.setNegativeButton("Retry", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dlg, int sumthin) {
            dispatchTakePictureIntent();
        }
    });
    alertadd.setPositiveButton("Done", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dlg, int sumthin) {
            dlg.dismiss();
        }
    });
    final Dialog dialog = alertadd.create();
    dialog.show();

    ImageView ivWahetLeft = (ImageView) dialog.findViewById(R.id.ivWahetLeft);
    ivWahetLeft.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            createIrisTemplate(textureWahetLeftFile, segmentationWahetLeftFile, USITHelper.ALGO_SEG_WAHET_SHORT, Constants.EYE_POSITION_LEFT);
            v.setClickable(false);
            v.setEnabled(false);
            ((ImageView) v).setImageBitmap(null);
        }
    });

    final ImageView ivCahtLeft = (ImageView) dialog.findViewById(R.id.ivCahtLeft);
    ivCahtLeft.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            createIrisTemplate(textureCahtLeftFile, segmentationCahtLeftFile, USITHelper.ALGO_SEG_CAHT_SHORT, Constants.EYE_POSITION_LEFT);
            v.setClickable(false);
            v.setEnabled(false);
            ((ImageView) v).setImageBitmap(null);
        }
    });

    ImageView ivWahetRight = (ImageView) dialog.findViewById(R.id.ivWahetRight);
    ivWahetRight.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            createIrisTemplate(textureWahetRightFile, segmentationWahetRightFile, USITHelper.ALGO_SEG_WAHET_SHORT, Constants.EYE_POSITION_RIGHT);
            v.setClickable(false);
            v.setEnabled(false);
            ((ImageView) v).setImageBitmap(null);
        }
    });

    ImageView ivCahtRight = (ImageView) dialog.findViewById(R.id.ivCahtRight);
    ivCahtRight.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            createIrisTemplate(textureCahtRightFile, segmentationCahtRightFile, USITHelper.ALGO_SEG_CAHT_SHORT, Constants.EYE_POSITION_RIGHT);
            v.setClickable(false);
            v.setEnabled(false);
            ((ImageView) v).setImageBitmap(null);
        }
    });

    ImageLoader imageLoader = ImageLoader.getInstance();
    imageLoader.displayImage("file:///" + segmentationWahetLeftFile, ivWahetLeft);
    imageLoader.displayImage("file:///" + segmentationCahtLeftFile, ivCahtLeft);
    imageLoader.displayImage("file:///" + segmentationCahtRightFile, ivCahtRight);
    imageLoader.displayImage("file:///" + segmentationWahetRightFile, ivWahetRight);
}

现在我发现在其他机器上(不是在我的机器上)会抛出一个错误:

MainActivity has leaked window that was originally added here

我感觉来自 onCreate() 方法的代码有时会取消对话框？虽然只有 UI 的东西和一些后端通信开始了

更新:在另一个设备(更快，SGS6 而不是 SGS$)上运行应用程序时，致命信号 11 (SIGSEGV)，代码 1，故障地址 0x24 in tid 12737 (RenderThread)。出现对话框，单击其中一个 ImageView 时出现此错误

最佳答案

尝试在 OnActivityResult 中设置一个您需要显示对话框的标志，并在 onResume 中检查该标志，然后在那里而不是在 中创建对话框OnActivityResult.

有关为什么在 Activity 生命周期方法中提交 fragment 事务(在本例中显示对话框)是一个坏主意的更多信息，请参见 here .

关于Android 不在 OnActivityResult 中显示对话框，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36158355/
