android中从java中获取图像时android中的java.lang.OutOfMemoryError
作者:互联网
我正在使用代码从图库中选择一张图片
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gallery);
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, SELECT_PICTURE);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SELECT_PICTURE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
picturePath = cursor.getString(columnIndex);
cursor.close();
Log.v("picturePath", "picturePath: " + picturePath);
Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
Intent intentUpload = new Intent(GalleryActivity.this, UploadActivity.class);
// intentUpload.putExtra("BitmapImage", bitmap);
MyApplicationGlobal.bitmap = bitmap;
startActivity(intentUpload);
finish();
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
但是我收到了错误

: D/AndroidRuntime(2487): Shutting down VM
解决方法:
尝试这个 :
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch (requestCode) {
case SELECT_PHOTO:
if (resultCode == RESULT_OK) {
Uri selectedImage = imageReturnedIntent.getData();
try {
picImageView.setImageBitmap(decodeUri(selectedImage));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
}
然后声明以下函数:
private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(
getContentResolver().openInputStream(selectedImage), null, o);
final int REQUIRED_SIZE = 100;
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
break;
}
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(
getContentResolver().openInputStream(selectedImage), null, o2);
}
谢谢.
