SetText does not set text in EditText

I had a problem that I had never had before almost three years of development with Android ...

I want to take a picture, and after the image is recorded, the EditText activity will become clear. What I'm doing is setting the values ​​of EditText - Strings , using getText().toString() to restore them after shooting.

Strings are perfectly saved with data, but when I use setText , it does not work ... It is strange that setHint works!

How can it be?

Here is the code I'm using:

 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) { if (resultCode == RESULT_OK) { // Image captured and saved to fileUri specified in the Intent grabImage(imgView); for (int u = 0; u <= 2; u++) { if (savedImgs[u].equals("")) { imgs = u + 1; savedImgs[u] = photo.toString(); break; } } /*Bitmap thumbnail = (Bitmap) data.getExtras().get("data"); ---> It is a small bitmap, for icons... imgView.setImageBitmap(thumbnail); imgView.setVisibility(View.VISIBLE);*/ } else if (resultCode == RESULT_CANCELED) { // User cancelled the image capture } else { Toast.makeText(this, "Image couldn't be taken. Try again later.", Toast.LENGTH_LONG).show(); } } if (!tempSpotName.equals("") || !tempSpotDesc.equals("")) { name.setText(tempSpotName); description.setText(tempSpotDesc); } }

name and description are global EditTexts and tempSpotName and tempSpotDesc are global Strings .

How to set the text?

onActivityResult() not the last method called when returning to Activity. You can update your life cycle memory in documents. :)

As we discussed in the comments, if you call setText() again in methods like onResume() , this will override any text set to onActivityResult() .

The same goes for Fragments, you need to make updates in the onViewStateRestored () method (which was added in API 17).

First of all you need to debug this.

There is a class called TextWatcher. This will be called every time your Textbox.Text changes. So it’s easier to debug and deal with this problem. Url: http://developer.android.com/reference/android/text/TextWatcher.html

Example for implementation:

name.addTextChangedListener (new TextWatcher () {

  @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { doSomething(); } });

Good luck :)

Several times changing the edittext in onactivity result does not work. I also faced the same problem

instead of setting

 edittext.settext("yourtext");

change to next in onactivityresult

 edittext.post(new Runnable(){ edittext.settext("yourtext"); });

It worked for me.

You can force EditText.SetText ("blablabla ..."); inside your OnActivity result in 3 easy steps:

  • Reload the layout in your activity.
  • Drag your EditText
  • use SetText as usual.

In this code example, I pass a URL string with both intentions and write them to a TextView:

 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK) { QRdata= data.getStringExtra("QRURL"); if (QRdata.length()>0) { //Step1 setContentView(R.layout.activity_confirmpackage); //Step2 TextView qrtxt=(TextView)this.findViewById(R.id.qrurl); //Setp 3,Voilà! qrtxt.setText(QRdata.toString()); }
