android --拍照，從相冊獲取圖片，兼容高版本，兼容小米手機

前幾天做項目中選擇圖片的過程中遇到高版本和小米手機出現無法選擇和崩潰的問題，現在記錄下來，后面出現同類問題，也好查找

1，定義常量：

private static final int TAKE_PICTURE = 3;
private static final int CHOOSE_PICTURE = 4;
private static final int CROP_SMALL_PICTURE = 5;

2，拍照，選擇相冊圖片邏輯，下面紅色部分就是兼容高版本和低版本選取相冊圖片的代碼，不會出現問題：

public void showPicturePicker(Context context) {
        final String[] stringItems = { "拍照", "相冊" };
        final ActionSheetDialog dialog = new ActionSheetDialog(this, stringItems, null);
        dialog.isTitleShow(false).show();

        dialog.setOnOperItemClickL(new OnOperItemClickL() {
            @Override
            public void onOperItemClick(AdapterView<?> parent, View view, int position, long id) {
                switch (position) {
                case 0:
                    Intent openCameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    // 指定照片保存路徑（SD卡），image.jpg為一個臨時文件，每次拍照后這個圖片都會被替換
                    openCameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
                    startActivityForResult(openCameraIntent, TAKE_PICTURE);
                    dialog.dismiss();
                    break;

                case 1:
                    Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,"image/*"); startActivityForResult(intent, CHOOSE_PICTURE); 
                    dialog.dismiss();
                    break;

                default:
                    break;
                }
            }
        });
    }

 

3，onActivityforResult里面的邏輯代碼：

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        String absolutePath = Environment.getExternalStorageDirectory().getAbsolutePath();
        String headpic = absolutePath + File.separator + "headpic.png";

        switch (requestCode) {
        case Constant.TO_CHANGENAMEACTIVITY_REQUESTCODE:
            if (data != null) {
                String name = data.getStringExtra("name").trim();
                if (!isNull(name)) {
                    tv_mine_name_content.setText(name);
                }
            }
            break;
        case TAKE_PICTURE:
            cropImageUri(imageUri, 154, 154, CROP_SMALL_PICTURE);
            break;

        case CHOOSE_PICTURE:
            if (data != null) {
                // 照片的原始資源地址
                Uri originalUri = data.getData();
                cropImageUri(originalUri, 154, 154, CROP_SMALL_PICTURE);
            }

            break;
        case CROP_SMALL_PICTURE:
            if(imageUri != null){
                Bitmap bitmap;
                try {
                    bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(uritempFile));
                    ImageTools.savePhotoToSDCard(bitmap, absolutePath, "headpic.png");
                    uploadHeadPic(headpic);
                    bitmap.recycle();
                } catch (FileNotFoundException e) {
                    toast("找不到圖片文件");
                    e.printStackTrace();
                } 
            }
            break;
        default:
            break;
        }
    }

注意uritempFile ，必須如下寫，否則在小米手機上肯定崩潰：

Uri uritempFile = Uri.parse("file://" + "/" + Environment.getExternalStorageDirectory().getPath() + "/" + "small.jpg");

上面有調用裁剪圖片的調用，代碼如下：

private void cropImageUri(Uri uri, int outputX, int outputY, int requestCode){
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setDataAndType(uri, "image/*");
        intent.putExtra("crop", "true");
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("outputX", outputX);
        intent.putExtra("outputY", outputY);
        intent.putExtra("scale", true);
        //        intent.putExtra("return-data", false);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uritempFile);
        intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
        intent.putExtra("noFaceDetection", true); // no face detection
        startActivityForResult(intent, requestCode);
    }
