我有一個activity A
我正在建造我自己的相機。在這個活動中,相機被打開,當使用按下按鈕拍攝照片時。使用安卓相機拍了幾張照片後出錯
這是這樣完成的:
Activity A:
//this button needs to be pressed to take the photo
public void onClick(View arg0) {
mCamera.takePicture(null, mPictureCallback, mPictureCallback);
}
//the method that gets called
Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {
public void onPictureTaken(byte[] imageData, Camera c) {
if (imageData != null) {
Intent mIntent = new Intent();
Bundle b = new Bundle();
b.putByteArray("imageData", imageData);
Intent i = new Intent(mContext, ViewPhoto.class);
i.putExtras(b);
startActivity(i);
setResult(FOTO_MODE, mIntent);
finish();
}
}
};
圖片發送到第二個活動,用戶可以查看它,看看它是否喜歡它或not.If他不喜歡這樣,他可以再重拍照片
活性B:
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
//..........
Bundle extras = getIntent().getExtras();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 2;
byte[] imageData = extras.getByteArray("imageData");
Bitmap myImage = BitmapFactory.decodeByteArray(imageData, 0,
imageData.length, options);
Matrix mat = new Matrix();
mat.postRotate(90);
bitmapResult = Bitmap.createBitmap(myImage, 0, 0, myImage.getWidth(),
myImage.getHeight(), mat, true);
//.......
}
在該第二活動我接收畫面的字節,並創建一個第一bitmap
:
Bitmap myImage = BitmapFactory.decodeByteArray(imageData, 0,
imageData.length, options);
之後,我需要旋轉first bitmap
創建第二位:用戶看到bitmapResult
bitmapResult = Bitmap.createBitmap(myImage, 0, 0, myImage.getWidth(),
myImage.getHeight(), mat, true);
後,他可以重新拍照。
backTakePhoto.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//...back to activity A
}
});
的問題是,服用了幾張照片後,循環,如:
activity A->activity B->activity A->Activity B my app crashes in activity B at this line:
bitmapResult = Bitmap.createBitmap(myImage, 0, 0, myImage.getWidth(),
myImage.getHeight(), mat, true);
,這是我的logcat的樣子:

任何想法?
如果U R感興趣,我會給你完整的圖像捕捉代碼使用相機,並在應用程序中使用。 –
那麼你可以給我,爲什麼不。 – adrian
