Fragment中的listview更新item中的Imageview
项目中需要实现保存图片到数据库，再次进入更新控件
- 展示图片到控件上
- 保存图片路径
- 设置全局变量，再次进入时根据全局变量来判断是否展示保存的图片路径
调取摄像头
Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//打开相机的Intent
if (takePhotoIntent!= null) {
//创建用来保存照片的文件
File imageFile = autoImageUtil.createImageFile();
if (imageFile != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
/*7.0以上要通过FileProvider将File转化为Uri*/
mImageUri = FileProvider.getUriForFile(mActivity, FILE_PROVIDER_AUTHORITY, imageFile);
} else {
/*7.0以下则直接使用Uri的fromFile方法将File转化为Uri*/
mImageUri = Uri.fromFile(imageFile);
}
//将用于输出的文件Uri传递给相机
takePhotoIntent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
//打开相机
startActivityForResult(takePhotoIntent, TAKE_PHOTO);
}
}
创建图片保存路径
public File createImageFile() {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
File imageFile = null;
try {
imageFile = File.createTempFile(imageFileName, ".jpg", storageDir);
} catch (Exception e) {
e.printStackTrace();
}
return imageFile;
}
- 在onActivityResult中判断是否拍摄成功，将图片保存到的imageUri，通过BitmapFractory生成Bitmap，将Bitmap保存到ImageBean对象中
if (resultCode == Activity.RESULT_OK) {
isSavedImage = false;
try {
imageBeans.clear();
ImageBean imageBean = new ImageBean();
/*如果拍照成功，将Uri用BitmapFactory的decodeStream方法转为Bitmap*/
Bitmap bitmap = BitmapFactory.decodeStream(mActivity.getContentResolver().openInputStream(mImageUri));
int bitmapDegree = CamerUtils.getBitmapDegree(mImageUri.getPath());
Log.e(TAG, "onActivityResult: 图片角度==" + bitmapDegree + mImageUri + bitmap);
Bitmap newBitmap = autoImageUtil.AddTimeWatermark(bitmap);
imageBean.setBitmap(newBitmap);
//保存水印图片
Map<String, String> stringStringMap = autoImageUtil.SaveImagFile(newBitmap);
imageBean.setBitmapPath(AutoImageUtil.getFilePathByUri(mActivity, mImageUri));
imageBean.ImagePath = stringStringMap;
// imageBean.setBitmapPath(AutoImageUtil.Uri2Path(mActivity,mImageUri));
imageBeans.add(imageBean);
//如果imageBean集合size发生变化 则通知quploadAdapter更新
qUploadAdapter.notifyDataSetChanged();
} catch (Exception e) {
e.printStackTrace();
Log.e(TAG, "onActivityResult: " + e.toString());
}
