Question

我正在尝试存储图像并在保存后裁剪它，但我有一个最大的问题，那个问题是当我存储图像时所有的东西都很好但是当我发送URI结果时，crop类打开但是它是空的没有图片 我认为它是空的，因为图像没有成功保存，因此它变为空，所以我认为解决方案是等到图像保存然后打开裁剪类，这是我的代码如下：

Capture.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(final View v) {

            mCamera.setCameraListener(new CameraListener() {
                @Override
                public void onPictureTaken(byte[] picture) {

                    Bitmap result = BitmapFactory.decodeByteArray(picture, 0, picture.length);
                    final Bitmap resizedbitmap = Bitmap.createScaledBitmap(result, 1200, 1200,false);
                    new Thread(new Runnable(){@Override public void run() {storeImage(resizedbitmap);}}).start();

                    if (getOutputMediaFile()!=null){
                        final Uri mUri = Uri.fromFile(new File(getOutputMediaFile().getPath()));
                        Intent var6 = new Intent();
                        var6.putExtra(MediaStore.EXTRA_OUTPUT,mUri);
                        setResult(RESULT_OK,var6);
                        finish();
                    }
                }
            });

            mCamera.captureImage();}}); 

private void storeImage(Bitmap image) {
    File pictureFile = getOutputMediaFile();

    if (pictureFile == null) {runOnUiThread(new Runnable() {
        @Override
        public void run() {Toast.makeText(camera_fragment.this,R.string.error,Toast.LENGTH_SHORT).show();}});return;}

    try {if (getOutputMediaFile()!=null && getOutputMediaFile().exists()){
        FileOutputStream fos = new FileOutputStream(pictureFile.toString());
        image.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();}}
    catch (IOException e) {

        runOnUiThread(new Runnable() {@Override public void run() {Toast.makeText(camera_fragment.this,R.string.error,Toast.LENGTH_SHORT).show();}});}
}

private File getOutputMediaFile(){
    File mediaStorageDir = new File(Environment.getExternalStorageDirectory() + "/Pictures/Test/");

    if (!mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){

            runOnUiThread(new Runnable() {
                @Override
                public void run() {Toast.makeText(camera_fragment.this,R.string.error,Toast.LENGTH_SHORT).show();}
            });

            return null;}}

    String timeStamp = new SimpleDateFormat("ddMMyyyyHHmmss",Locale.US).format(new Date());
    File mediaFile;
    String mImageName=timeStamp +".png";
    mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);
    sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(mediaFile)));
    return mediaFile;
}

我也使用Handler等待3秒钟我使用了TimerTask和所有方法，但直到现在我都没有用。

所以请兄弟们解决这个问题。

我在logcat中看不到任何东西，这就是我所拥有的：
