相机意图不适用于三星 Galaxy S3 [英] Camera intent not working with Samsung Galaxy S3
本文介绍了相机意图不适用于三星 Galaxy S3的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个活动，我让用户可以选择从相机单击图像，然后将此图像存储在字节数组和数据库中.但是我的代码似乎在三星 Galaxy S3 上不起作用，下面是代码:
I have an activity wherin I give the user an option to click an image from the camera, then I store this image in a byte array and in the Database. However my code does not seem to work on Samsung Galaxy S3 below is the code:
摄像头调用意图:
if (i == 0) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
关于相机的活动方法:
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);
}
}
我的图片(位图缩略图)功能:
My image(Bitmap thumbnail) function:
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);
}
然而，这不适用于三星 S3，我将代码更改为以下代码，现在它适用于三星 S3，但不适用于任何其他设备.
However this was not working with Samsung S3, I changed the code to the following and now it works with Samsung S3, however it does not work with any other device.
相机意图:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
结果活动:
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 image() 函数:
This is my image() function:
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();
}
}
虽然所有三个 1)uriLargeImage 2)largeImagePath 3)uriThumbnailImage 都返回路径或 URI，但我无法将创建的位图设置为我的 ImageView.然而，这只是三星 S3 的情况，如果我用任何其他设备运行上面编辑的代码，程序就会崩溃.
While as all the three 1)uriLargeImage 2)largeImagePath 3)uriThumbnailImage return me the path or URI I am unable to set the created bitmap to my ImageView. However this is the case with Samsung S3 only, if I run the above edited code with any other device, the program crashes.
在我使用的清单中
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，如果我在横向模式下拍照，一切正常！我很纳闷！！(在三星 S3 中)
However if I take the picture in Landscape mode, everything works fine! I am puzzled!! (In Samsung S3)
推荐答案
终于在挣扎了三天之后，我设计了一个简单的机制来克服三星 S3 Saga.
Finally after struggling for three days, I have devised a simple mechanism to overcome the Samsung S3 Saga.
下面是代码，代码的快速总结是我首先检查设备的制造商，并基于此我为相机调用不同的意图.
Below is the code, a quick summary of the code is that I first check the Manufacturer of the device and based on this I call different intents for camera.
public class MainActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
private static final int PICK_FROM_GALLERY = 2;
int CAMERA_PIC_REQUEST = 1337;

private static final int OG = 4;
private static final int CAMERA_IMAGE_CAPTURE = 0;
Uri u;
ImageView imgview;
// int z=0;
String z = null;
byte b[];
String largeImagePath = "";
Uri uriLargeImage;
Uri uriThumbnailImage;
Cursor myCursor;
public void imageCam(Bitmap thumbnail) {
Bitmap photo = thumbnail;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
photo.compress(Bitmap.CompressFormat.JPEG, 70, bos);
b = bos.toByteArray();
ImageView imageview = (ImageView) findViewById(R.id.imageView1);
imageview.setImageBitmap(photo);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button bt = (Button) findViewById(R.id.button1);
bt.setOnClickListener(onBTN);
if (savedInstanceState != null) {
Bitmap Zatang;
String B1 = savedInstanceState.getString("message");
Toast.makeText(this, "SavedYeah" + B1, Toast.LENGTH_LONG).show();
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inSampleSize = OG;
Zatang = BitmapFactory.decodeFile((B1), opts);
System.gc();
if (Zatang != null) {
Toast.makeText(this, "Success Zatang" + B1, Toast.LENGTH_LONG)
