通過意圖從相機捕獲后如何裁剪圖像：Android

Question

我想從相機獲取圖像捕獲圖像，並想通過android gallery的裁剪活動將其裁剪為固定的長寬比和固定的大小。

此代碼是為畫廊，我想為相機

    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    photoPickerIntent.setType("image/*");
    photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.PNG.toString());
    photoPickerIntent.putExtra("crop", "true");
    photoPickerIntent.putExtra("scale", "true");
    photoPickerIntent.putExtra("aspectX", 1);
    photoPickerIntent.putExtra("aspectY", 1);
    photoPickerIntent.putExtra("outputX", 100);
    photoPickerIntent.putExtra("outputY", 100);
    startActivityForResult(photoPickerIntent, SELECT_PHOTO);

Answer 1

public void cropCapturedImage（Uri picUri）{/ Intent intent = new Intent（）; intent.setType（“ image / ”）; intent.setAction（Intent.ACTION_PICK）; startActivityForResult（intent，GALLERY）; * /

    // System.out.println("cropCapturedImage picUri=" + picUri);
    // call the standard crop action intent
    Intent cropIntent = new Intent("com.android.camera.action.CROP");
    // indicate image type and Uri of image
    cropIntent.setDataAndType(picUri, "image/*");
    // set crop properties
    cropIntent.putExtra("crop", "true");
    // indicate aspect of desired crop
    cropIntent.putExtra("aspectX", 2);
    cropIntent.putExtra("aspectY", 1);
    // indicate output X and Y
    cropIntent.putExtra("outputX", 256);
    cropIntent.putExtra("outputY", 256);
    // retrieve data on return
    cropIntent.putExtra("return-data", true);
    // start the activity - we handle returning in onActivityResult
    startActivityForResult(cropIntent, 2);
}
