我尝试从图库中选择一个图像并将位图设置为我的imageview,但我遇到了一个问题:在我的设备中,效果很好,但在其他设备中无效。
我在片段中启动图像选择器,如下所示:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
这是我的onActivityResult
:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
Log.d("ResultCode",resultCode+"");
switch (requestCode) {
case SELECT_PHOTO:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageReturnedIntent.getData();
try {
Bitmap imagen = decodeUri(selectedImage);
// Works on my device (because resultCode = RESULT_OK) but doesn't work in others (because resultCode = 0)
((ImageView) findViewById(R.id.myimage)).setImageBitmap(imagen);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
}
我会感激任何帮助,我有点绝望。 X_X

我遇到过这个问题......非常有趣。有三种不同的方式可以选择照片,就像你说的那样,由于某种原因,它并不总能在所有设备上正常工作。经过几个小时的折磨,我发现这一点始终如一:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent,"whatever you want",1);
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode)
{
case 1:
if (resultCode == RESULT_OK)
{
Uri selectedImage = data.getData();
}
break;
}
}
