我有一个活动wherin我给用户一个选项,点击从相机的图像,然后我把这个图像存储在一个字节数组和数据库。我的代码似乎但是并没有对三星Galaxy S3工作,下面是代码:相机意图不能与三星Galaxy S3
摄像头调用的意图:
if (i == 0) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
在相机活动方法:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1337 && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
if (extras != null) {
BitmapFactory.Options options = new BitmapFactory.Options();
thumbnail = (Bitmap) extras.get("data");
image(thumbnail);
} else {
Toast.makeText(CreateProfile.this, "Picture NOt taken", Toast.LENGTH_LONG).show();
}
super.onActivityResult(requestCode, resultCode, data);
}
}
我的图像(位图缩略图)功能:
public void image(Bitmap thumbnail) {
Bitmap photo = thumbnail;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
b = bos.toByteArray();
ImageView imageview = (ImageView)findViewById(R.id.imageView1);
Bitmap bt = Bitmap.createScaledBitmap(photo, 100, 80, false);
imageview.setImageBitmap(bt);
}
但是,这不是与三星S3的工作,我改变了C颂赞以下,现在它可以与三星S3一起使用,但它不适用于任何其他设备。
相机意图:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
活动为结果:
startActivityForResult(intent, CAMERA_IMAGE_CAPTURE);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_IMAGE_CAPTURE && resultCode == Activity.RESULT_OK) {
// Describe the columns you'd like to have returned. Selecting from the Thumbnails location gives you both the Thumbnail Image ID, as well as the original image ID
String[] projection = {
MediaStore.Images.Thumbnails._ID, // The columns we want
MediaStore.Images.Thumbnails.IMAGE_ID,
MediaStore.Images.Thumbnails.KIND,
MediaStore.Images.Thumbnails.DATA};
String selection = MediaStore.Images.Thumbnails.KIND + "=" + // Select only mini's
MediaStore.Images.Thumbnails.MINI_KIND;
String sort = MediaStore.Images.Thumbnails._ID + " DESC";
//At the moment, this is a bit of a hack, as I'm returning ALL images, and just taking the latest one. There is a better way to narrow this down I think with a WHERE clause which is currently the selection variable
Cursor myCursor = this.managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, projection, selection, null, sort);
long imageId = 0l;
long thumbnailImageId = 0l;
String thumbnailPath = "";
try{
myCursor.moveToFirst();
imageId = myCursor.getLong(myCursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
thumbnailImageId = myCursor.getLong(myCursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
thumbnailPath = myCursor.getString(myCursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
}
finally{myCursor.close();}
//Create new Cursor to obtain the file Path for the large image
String[] largeFileProjection = {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA
};
String largeFileSort = MediaStore.Images.ImageColumns._ID + " DESC";
myCursor = this.managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, largeFileProjection, null, null, largeFileSort);
String largeImagePath = "";
try{
myCursor.moveToFirst();
//This will actually give yo uthe file path location of the image.
largeImagePath = myCursor.getString(myCursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
}
finally{myCursor.close();}
// These are the two URI's you'll be interested in. They give you a handle to the actual images
Uri uriLargeImage = Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, String.valueOf(imageId));
Uri uriThumbnailImage = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, String.valueOf(thumbnailImageId));
// I've left out the remaining code, as all I do is assign the URI's to my own objects anyways...
// Toast.makeText(this, ""+largeImagePath, Toast.LENGTH_LONG).show();
// Toast.makeText(this, ""+uriLargeImage, Toast.LENGTH_LONG).show();
// Toast.makeText(this, ""+uriThumbnailImage, Toast.LENGTH_LONG).show();
if (largeImagePath != null) {
// Toast.makeText(this, "" + largeImagePath, Toast.LENGTH_LONG).show();
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inSampleSize = OG;
// thumbnail = (BitmapFactory.decodeFile(picturePath));
thumbnail = BitmapFactory.decodeFile((largeImagePath), opts);
System.gc();
if (thumbnail != null) {
Toast.makeText(this, "Success", Toast.LENGTH_LONG).show();
}
image(thumbnail);
}
if (uriLargeImage != null) {
Toast.makeText(this, "" + uriLargeImage, Toast.LENGTH_LONG).show();
}
if (uriThumbnailImage != null) {
Toast.makeText(this, "" + uriThumbnailImage, Toast.LENGTH_LONG).show();
}
}
这是我的图像()函数:
public void image(Bitmap thumbnail) {
b = null;
Bitmap photo = thumbnail;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.PNG, 100, bos);
b = bos.toByteArray();
if (b != null) {
Toast.makeText(this, "Success Yeah" + b, Toast.LENGTH_LONG).show();
}
}
虽然作为所有三个1)uriLargeImage 2) largeImagePath 3)uriThumbnailImage返回路径或URI我无法将创建的位图设置为我的ImageView。但是,只有三星S3才是这种情况,如果我使用任何其他设备运行上述编辑过的代码,程序会崩溃。
在清单我用
android:configChanges="keyboardHidden|orientation"
基于教程:http://kevinpotgieter.wordpress.com/2011/03/30/null-intent-passed-back-on-samsung-galaxy-tab/
但是,如果我走在风景模式下的画面,一切正常!我很困惑! (在三星S3)
我遇到了与此特定设备相同的问题。经过多次反复试验,我已经解决了这个问题。你可能会更好地了解这个问题从[这里](http://stackoverflow.com/questions/14495304/camera-force-closing-issue-in-samsung-galaxy-s3-version-4-1-1/14640678 #14640678) – 2013-03-06 13:21:03
上面的引用是同一个伴侣,我从同一个教程中引用了它,而一切看起来都很好,唯一的问题是我丢失了某处不应该发生的声明。 – Skynet 2013-03-06 13:22:31
你介意链接你的项目吗?我不介意测试一些东西。 – 2013-03-07 00:17:52
