android - Enabling the Edittext on selecting Item from Spinner -
hello friends trying enable edittext depending upon selection of records.the xml file below:
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <spinner android:id="@+id/per_id" android:layout_width="fill_parent" android:layout_height="wrap_content" android:spinnermode="dropdown" android:gravity="center" android:layout_margintop="20dp"/> <spinner android:id="@+id/columntoupdate" android:layout_width="fill_parent" android:layout_height="wrap_content" android:spinnermode="dialog" android:gravity="center" android:layout_margintop="20dp"/> <edittext android:id="@+id/entertoupdatestring" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_margintop="20dp" android:inputtype="text" android:hint="@string/enterthetexthere"/> <edittext android:id="@+id/entertoupdateint" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_margintop="20dp" android:inputtype="number" android:hint="@string/enterthenumberhere"/> <button android:id="@+id/clicktoupdate" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/clicktoupdate"/> </linearlayout> and java code applying below :-
package com.indianic.databaseprac; import java.util.arraylist; import java.util.list; import android.app.activity; import android.database.cursor; import android.os.bundle; import android.util.log; import android.view.view; import android.widget.adapterview; import android.widget.adapterview.onitemselectedlistener; import android.widget.arrayadapter; import android.widget.button; import android.widget.edittext; import android.widget.spinner; public class updatefrom25table extends activity { string id, column, text; edittext integertext; edittext stringtext; @override protected void oncreate(bundle savedinstancestate) { // todo auto-generated method stub super.oncreate(savedinstancestate); setcontentview(r.layout.update_from_25_table); stringtext = (edittext) findviewbyid(r.id.entertoupdatestring); integertext = (edittext) findviewbyid(r.id.entertoupdateint); stringtext.setvisibility(view.gone); integertext.setvisibility(view.gone); button updatebutton = (button) findviewbyid(r.id.clicktoupdate); // here setting spinner taking content of // table per_id having unique ids , setting spinner spinner spinnerid = (spinner) findviewbyid(r.id.per_id); final database25tablehandler db = new database25tablehandler( getapplicationcontext()); list<string> ids = db.gettingid(); arrayadapter<string> dataadapter = new arrayadapter<string>(this, android.r.layout.simple_spinner_item, ids); dataadapter .setdropdownviewresource(android.r.layout.simple_dropdown_item_1line); spinnerid.setadapter(dataadapter); // here setting column names in second spinner // of cursor. spinner spinnercolumn = (spinner) findviewbyid(r.id.columntoupdate); list<string> column = db.getcolumnname(); arrayadapter<string> dataadaptercolumn = new arrayadapter<string>(this, android.r.layout.simple_spinner_item, column); dataadaptercolumn .setdropdownviewresource(android.r.layout.simple_dropdown_item_1line); spinnercolumn.setadapter(dataadaptercolumn); final string spinnerselectedid = (string) spinnerid.getselecteditem(); final string spinnerselectedcolumn = (string) spinnercolumn .getselecteditem(); spinnercolumn.setonitemselectedlistener(new onitemselectedlistener() { @override public void onitemselected(adapterview<?> parent, view view, int pos, long id) { log.d("testing", parent.getitematposition(pos).tostring()); // todo auto-generated method stub if(parent.getitematposition(pos).tostring() == "reg_id") { //integertext.setenabled(true); log.d("testing", "looooggggg"); integertext.setvisibility(view.visible); text = integertext.gettext().tostring(); } else if (parent.getitematposition(pos).tostring() == "first_name") { //stringtext.setenabled(true); stringtext.setvisibility(view.visible); text = stringtext.gettext().tostring(); } } @override public void onnothingselected(adapterview<?> arg0) { // todo auto-generated method stub } }); // here setting items selected in string in // order perform update process. updatebutton.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { // todo auto-generated method stub db.updaterow(spinnerselectedid, spinnerselectedcolumn, text); db.close(); } }); } } here when selecting reg_id spinner not entering first if part log.d("testing", "looooggggg"); not printed
try this..
if comparing string should use .equels
if(parent.getitematposition(pos).tostring().equels("reg_id")) { //integertext.setenabled(true); log.d("testing", "looooggggg"); integertext.setvisibility(view.visible); text = integertext.gettext().tostring(); } else if (parent.getitematposition(pos).tostring().equels("first_name")) { //stringtext.setenabled(true); stringtext.setvisibility(view.visible); text = stringtext.gettext().tostring(); } == compares 2 references (for non-primitives, is) - i.e. tests whether 2 operands refer same object.
however, equals method can overridden - 2 distinct objects can still equal
edit
if(parent.getitematposition(pos).tostring().equalsignorecase("reg_id") || parent.getitematposition(pos).tostring().equels("first_name")){ }
