【中文标题】Android“拍照” - 单击的图像被保存为损坏的图像【英文标题】：Android "TAKE PHOTO" - Image which is clicked is getting saved as a corrupt image 【发布时间】：2015-07-30 18:41:24 【问题描述】：我有一个按钮，它会打开一个对话框，要求用户选择“拍照”或“从图库中选择”。
我遇到问题，当用户“拍照”时，图像被点击，出于验证目的，我在圆形图像视图中设置位图图像，但是当我转到指定的位置路径时图像，图像不存在或图像已损坏。
我还尝试在 android 中使用 AsyncHttpClient 将图像上传到服务器，但无法成功。
每次我收到 Java Socket TimeOut 异常。
下面是我的Camera Intent Activity
的代码public class AddAnUpdateActivity extends ActionBarActivity
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
this.composeEditText = (EditText) findViewById(R.id.composeEditText);
setContentView(R.layout.add_update);
ProfilePictureImage = (CircularImageView) findViewById(R.id.ProfilePic);
insertVideo = (ImageButton) findViewById(R.id.insertVideoButton);
setBtnListenerOrDisable(insertVideo,mTakeVidOnClickListener, MediaStore.ACTION_VIDEO_CAPTURE);
insertImage = (ImageButton) findViewById(R.id.insertImageButton);
insertImage.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
selectImage();
);
private void setBtnListenerOrDisable(ImageButton btn,
Button.OnClickListener onClickListener,
String intentName)
if (isIntentAvailable(this, intentName))
btn.setOnClickListener(onClickListener);
else
btn.setClickable(false);
private boolean isIntentAvailable(Context context, String action)
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
List<ResolveInfo> list =
packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
private void selectImage()
final CharSequence[] options = "Take Photo", "Choose from Gallery","Cancel" ;
AlertDialog.Builder builder = new AlertDialog.Builder(AddAnUpdateActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options,new DialogInterface.OnClickListener()
@Override
public void onClick(DialogInterface dialog, int item)
if(options[item].equals("Take Photo"))
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "Image.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));

【问题讨论】：
为什么使用 ACTION_VIDEO_CAPTURE 进行图像捕捉？对于图像捕获，必须使用 ACTION_IMAGE_CAPTURE 和 EXTRA_OUTPUT 来定位图像。 我在早期版本的应用程序中进行了视频捕获！我需要评论该代码！ 您发布了很多代码。如果是，请删除最多。只留下有问题的代码。并告诉代码应该做什么。同时删除上传代码。您最好将其作为单独的帖子发布。 您已经为私有 ImageButton insertImage 声明了变量；私人图像按钮插入视频；那么为什么要为视频调用“ImageButton.OnclickListener”，也许您必须编写 insertVideo.OnclickListener。 有没有给外部存储添加读写权限。 【参考方案1】：我简化了你的代码。保持全局文件路径引用
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "Image.jpg");
globalpath =f.getAbsolutePath(); //String make it global
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
//你的活动结果
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK)
if (requestCode == 1)
File myfile = new File(globalpath);
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(myfile.getAbsolutePath(),
bitmapOptions);
ProfilePictureImage.setImageBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Pictures" + File.separator + "Screenshots";
OutputStream outFile;
File file = new File(path, String.valueOf(System
.currentTimeMillis()) + ".jpg");
try
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
myfile.delete();
catch (Exception e)
e.printStackTrace();

【参考方案2】：根据您的 Android 版本和设备，相机 Intent 的实现方式会有所不同。查看https://github.com/ralfgehrer/AndroidCameraUtil。该代码在 100 多台设备上进行了测试。

【参考方案3】：拍照后记得用这个：
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
扫描您画廊中的媒体文件。如果你不这样做，你的照片会在一段时间后出现。您可以在 onClick 中完成：
insertImage.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
selectImage();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
);

以上是关于Android“拍照” - 单击的图像被保存为损坏的图像的主要内容，如果未能解决你的问题，请参考以下文章
Excel图像损坏，没有被指定在windows上运行，或者包含错误怎么办？
当我尝试捕获图像（内置相机）并将其保存到文件时出现 NullPointerException [重复]
