Question

首先 - 对不起我的英语不好。我试图从相机照片中获取作物。

这是我的openCamera方法：

private void openCamera() {

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT,
            MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
    // ******** code for crop image
    intent.putExtra("crop", "true");
    intent.putExtra("aspectX", 0);
    intent.putExtra("aspectY", 0);
    intent.putExtra("outputX", 200);
    intent.putExtra("outputY", 150);

    try {

        intent.putExtra("return-data", true);
        startActivityForResult(intent, PICK_FROM_CAMERA);

    } catch (ActivityNotFoundException e) {
    // Do nothing for now
    }
}

这是ActivityForResult：

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {

        if (requestCode == PICK_FROM_CAMERA) {
            Bundle extras = data.getExtras();
            if (extras != null) {
                photo = extras.getParcelable("data");
            }
        }
    }

但它崩溃了......

                                                   at

绝对不知道......

使用以下代码

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", 256);    
cropIntent.putExtra("outputY", 256);    
cropIntent.putExtra("return-data", true);    
startActivityForResult(cropIntent, PIC_CROP);

和OnActivityResult()方法 Bundle extras = data.getExtras(); //get the cropped bitmap Bitmap thePic = extras.getParcelable("data");

无法从相机裁剪图像
