Question

我有一个表单，用户可以从图库中选择图像或拍摄图像。当用户拍摄图像时它工作正常但当用户从图库中选择图像时它无法正常工作，然后我要求裁剪图像的意图。

在模拟器上裁剪来自画廊作品的图像但是在我测试过的2部手机上，当我选择裁剪应用程序时，裁剪应用程序崩溃或者如果它没有破碎，它就不起作用并显示imageView上的图像。

这是我的代码：

    final int PIC_CROP = 2;
    final int CAMERA_CAPTURE = 1;
    final int PICK_FROM_FILE = 3;
    private Uri picUri;

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == CAMERA_CAPTURE && resultCode == RESULT_OK) {

            picUri = data.getData();// get image URI
            performCrop();
        } else if (requestCode == PIC_CROP) {// crop and compress image
            if (resultCode != RESULT_OK)
                return;
            Bundle extras = data.getExtras();
            Bitmap thePic = extras.getParcelable("data");
            FileOutputStream out = null;
            ByteArrayOutputStream bao = new ByteArrayOutputStream();
            double width = thePic.getWidth();
            double height = thePic.getHeight();
            double ratio = 650 / width;
            int newheight = (int) (ratio * height);
            thePic = Bitmap.createScaledBitmap(thePic, 650, newheight, true);
            try {
                out = new FileOutputStream(file);
                thePic.compress(Bitmap.CompressFormat.JPEG, 295, out);
                thePic.compress(Bitmap.CompressFormat.JPEG, 295, bao);

                byte[] ba = bao.toByteArray();
                switch (whichimg) {
                case 1:
                    simg1 = Base64.encodeBytes(ba);
                    break;
            } catch (Exception e) {

            }

        }
    }

if (item == 0) {// take photo
                    Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    startActivityForResult(captureIntent, CAMERA_CAPTURE);
                    alert.dismiss();
                } else if (item == 1) {// photo from gallery
                    Intent intent = new Intent();
                    intent.setType("image/*");
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    startActivityForResult(
                            Intent.createChooser(intent, (getString(R.string.choosephototo))),
                            CAMERA_CAPTURE);
                    alert.dismiss();
                }

这是裁剪代码：

private void performCrop() {
    try {
        Intent cropIntent = new Intent("com.android.camera.action.CROP");
        cropIntent.setDataAndType(picUri, "image/*");
        cropIntent.putExtra("crop", "true");
        //cropIntent.putExtra("aspectX", 1);
        //cropIntent.putExtra("aspectY", 1);
        //cropIntent.putExtra("outputX", 356);
        //cropIntent.putExtra("outputY", 256);
        cropIntent.putExtra("return-data", true);
        startActivityForResult(cropIntent, PIC_CROP);
    } catch (ActivityNotFoundException anfe) {
        MyToast.makeText(NewAdd2.this, DariGlyphUtils.reshapeText(getString(R.string.devicecouldcop)));
    }
}

你可以帮帮我吗？为什么它不能正常工作？

谢谢

尝试下面的问题链接，它会起作用

可能在performCrop（）方法中出现问题

从图库中删除android-image裁剪不能正常工作
