这是代码。我正在尝试创建一个新的子节点并保存数据，但是没有在firebase树上创建节点。但代码运行成功。但是在更新了sdk后，它无法正常工作。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_post__feed);
initialize();
btn_post_feed.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
UploadData();
}
});
}
private void initialize() {
edt_details = (EditText) findViewById(R.id.post_feed_description);
spinner_category = (Spinner) findViewById(R.id.post_feed_spinner);
seekBar = (SeekBar) findViewById(R.id.post_feed_number);
btn_post_feed = (Button) findViewById(R.id.post_feed_btn_post);
sharedPreferences = getSharedPreferences("MODE", Context.MODE_PRIVATE);
phn = sharedPreferences.getString("mobno", "A");
value = sharedPreferences.getInt("value", 0);
}
@Override
public void UploadData() {
reference1 = FirebaseDatabase.getInstance().getReference().child("feeds");
detailsFeeds = new DetailsFeeds();
detailsFeeds.setCategory(category);
detailsFeeds.setItemDonateName(quantity);
detailsFeeds.setPhoneNo(phn);
detailsFeeds.setItemDonateName(details);
if (value == 1)
detailsFeeds.setStatus(true);
else
detailsFeeds.setStatus(false);
reference2 = reference1.child(phn + detailsFeeds.getPostNumber());
detailsFeeds.increasePostnumber();
detailsFeeds.setPostNumber(detailsFeeds.getPostNumber());
reference2.setValue(detailsRegister, new DatabaseReference.CompletionListener() {
@Override
public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) {
if (databaseError == null) {
setResult(789);
finish();
} else {
Toast.makeText(getApplicationContext(), "Failed", Toast.LENGTH_SHORT).show();
setResult(786);
finish();
}
}
});
}
@Override
public void DownloadData() {
}
@Override
public void FetchFields() {
spinner_category.setOnItemSelectedListener(new CustomItemSelectedListener());
details = edt_details.getText().toString();
quantity = String.valueOf(seekBar.getProgress());
}
@Override
public boolean CheckFields() {
return false;
}
private class CustomItemSelectedListener implements AdapterView.OnItemSelectedListener {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
category = adapterView.getItemAtPosition(i).toString();
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}
}
