android:layout_height="wrap_content"

android:textSize="14dp"
android:layout_alignParentLeft="true"

On the possible issue that i faced once and suspects is: The EditText might be contained in an XML layout file and the layout file will be used for a Dialog instance. The problem occurs when the onKeyListener of the Dialog instance is returning some invalid default value i.e. ‘return true’ for irrelevant keys. In such case your EditText will be behaving strangely. The sample code for the scenario is

Dialog d=new Dialog(context);
    d.setContentView(R.layout.mylayout);
    d.setOnKeyListener(new OnKeyListener() {

                    @Override
                    public boolean onKey(DialogInterface dialog, int keyCode,
                            KeyEvent event) {
                        Log.i("onkey", keyCode + " == Onkey");
                        if (keyCode == KeyEvent.KEYCODE_BACK) {
                                return true;
                        }
                        return true;  // !!! this is wrong it should be return false;
                    }
                });
            }
