android-edittext

问题 I read that Android automatically saves the content of EditText objects when an application is about to be stopped or killed. However, in my app the content of an EditText is lost when screen orientation changes. Is it normal behaviour? Do I then have to manually save/restore its content with onSaveInstanceState / onRestoreInstanceState ? Or is there an easier method to tell Android to save it end restore it? Edit : I create the EditText object programmatically, not in XML. This turns out to

问题 I have an edit text which functions as a search box in my application. In Jelly Bean on my Nexus 7 when I type something into the text box which I am listening on and hit enter the KeyEvent = null and ActionId = 0 passed into the onEditorAction() method. Has anyone else encountered this? I'm thinking it might be a bug. In the second if statement below I get a null pointer because the actionId = 0 and KeyEvent = null; // Search field logic. @Override public boolean onEditorAction(TextView v,

问题 I've created a ListView (myList) with one EditText-Field in each row (R.id.mannschaften). Under the ListView, I've created a Button and set an OnClickListener for it in the OnCreate()-Method. Now when the Button is clicked, I want to iterate through the ListView and get the value of the EditText-Field in every row and save them in a String-List. But how do I do that? Here is my Code: private void ButtonClick() { /** get all values of the EditText-Fields */ View v; ArrayList<String>

问题 I have searched and searched for an answer to this question and everything that looked like an answer has not worked so I guess I will just ask. I have a couple of EditText boxes added to a ListView that is the basis to a ListActivity . When I set the windowSoftInputMode to adjustPan and click in an EditText it works until you click on it again and then the keyboard covers it up.

If the cursor is moved, this is called as well (in this case selStart == selEnd)

问题 I want an EditText which creates a DatePicker when is pressed. So I write the following code: mEditInit = (EditText) findViewById(R.id.date_init); mEditInit.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showDialog(DATEINIT_DIALOG); } }); But when I press the EditText the action is the typical: a cursor waiting for typing text instead show the Dialog I want. 回答1: The keyboard seems to pop up when the EditText gains focus. To prevent this, set focusable
