您好我有以下代码，让您使用捕获图像或从图库中选择它。我捕获一个图像保存它，然后尝试从库中选择图像，画廊应用程序始终崩溃。
AlertDialog.Builder photoDialog = new AlertDialog.Builder(this);
photoDialog
.setTitle("Photo source")
.setCancelable(true)
.setPositiveButton("Open Gallery",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
startActivityForResult(
new Intent( Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI),
54);
}
})
.setNegativeButton("Open Camera",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
String fileName = "temp.jpg";
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE,
fileName);
mCapturedImageURI = getContentResolver()
.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent( MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
startActivityForResult(intent, 96);
}
});
photoDialog.show();

答案 0 :(得分：0)
使用此：
Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
和onActivityResult：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == getActivity().RESULT_OK){
Uri picUri = imageReturnedIntent.getData();
}
break;
}
}
