我正在尝试发送短信和彩信的应用程序,因此我需要检索电话号码并最终检索图像。
我的问题是,如果我只是 onActivityResult 中的 PICK_CONTACT 案例,它工作正常,我收到了我的联系电话号码。
但如果我添加第二部分 PICK_IMAGE ,当我点击我的联系人时,我得到了:
java.lang.IllegalArgumentException: Invalid column _data
但是我仍然可以毫无问题地拍摄图像。
private static final int PICK_CONTACT = 3;
private static final int PICK_IMAGE = 4;
protected void onCreate(Bundle savedInstanceState) {
...
}
public void addImage() {
Intent choosePictureIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(choosePictureIntent,PICK_IMAGE );
}
public void addContact(){
Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT);
}
public void onActivityResult(int reqCode, int resultCode, Intent data){
super.onActivityResult(reqCode, resultCode, data);
Uri contactData = data.getData();
switch(reqCode) {
case (PICK_CONTACT):
if (resultCode == Activity.RESULT_OK) {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
if (cur.moveToFirst()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
while (pCur.moveToNext()) {
phone = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
etPhoneNo.setText(phone);
}
pCur.close();
}
}
case (PICK_IMAGE) :
if (resultCode == Activity.RESULT_OK) {
try {
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
bmpFactoryOptions.inSampleSize = 2;
bmpFactoryOptions.inJustDecodeBounds = false;
Bitmap bmp = BitmapFactory.decodeStream(getContentResolver().openInputStream(contactData), null, bmpFactoryOptions);
imageView.setImageBitmap(bmp);
} catch (FileNotFoundException e) {
Log.v("ERROR", e.toString());
}
ContentResolver cr = getContentResolver();
String [] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = cr.query(contactData, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
image_path = cursor.getString(column_index);
}
}
}
我该如何解决?
