date picker dialog show on edit text double click

I have a search activity with two edit text fields. I like on edit text click date picker dialog to be show. However when I click on edit text, first the keyboard is shown, then after second click the date picker dialog is shown. Could somebody help me?
Here is activity code
package com.example.firstdemoapp.activities;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;
import com.example.firstdemoapp.R;
import com.example.firstdemoapp.model.StatusDK;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.Spinner;
public class SearchingTaxActivity extends Activity implements OnClickListener,
DatePickerDialog.OnDateSetListener, OnItemSelectedListener {
private Calendar calendarFrom;
private Calendar calendarTo;
private String myFormat;
private SimpleDateFormat sdf;
private EditText dateFrom;
private EditText dateTo;
private EditText activeEditText;
private Calendar activeCalendar;
private Spinner spinnerStatusDK;
private ArrayAdapter spinnerArrayAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_tax);
calendarFrom = Calendar.getInstance();
calendarTo = Calendar.getInstance();
myFormat="dd/MM/yyyy";
sdf = new SimpleDateFormat(myFormat, Locale.US);
dateFrom = (EditText) findViewById(R.id.dateFrom);
dateTo = (EditText) findViewById(R.id.dateTo);
spinnerStatusDK=(Spinner)findViewById(R.id.spinnerStatusDK);
spinnerArrayAdapter = new ArrayAdapter(this,
android.R.layout.simple_spinner_item, new StatusDK[] {
new StatusDK( 0, "0" ),
new StatusDK( 1, "1" ),
new StatusDK( 2, "2" ),
});
spinnerStatusDK.setAdapter(spinnerArrayAdapter);
spinnerStatusDK.setOnItemSelectedListener(this);
dateFrom.setOnClickListener(this);
dateTo.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v == dateFrom) {
activeCalendar = calendarFrom;
activeEditText = dateFrom;
} else if (v == dateTo) {
activeCalendar = calendarTo;
activeEditText = dateTo;
}
new DatePickerDialog(SearchingTaxActivity.this, this,
activeCalendar.get(Calendar.YEAR),
activeCalendar.get(Calendar.MONTH),
activeCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
activeCalendar.set(Calendar.YEAR, year);
activeCalendar.set(Calendar.MONTH, monthOfYear);
activeCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
if (activeEditText != null) {
activeEditText.setText(sdf.format(activeCalendar.getTime()));
}
}
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
and the layout for the activity is:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/dateFromTextView"
/>
<EditText
android:id="#+id/dateFrom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/edit_datefrom"
/>
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/dateToTextView"
/>
<EditText
android:id="#+id/dateTo"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="#string/edit_dateto"
/>
<Spinner
android:id="#+id/spinnerStatusDK"
android:layout_width="match_parent"
android:layout_height="wrap_content" />

I added android:focusableInTouchMode="false" for edit text in the xml file and this helped me. Because first focus event is fired, and then click event is fired.

you can try to hide a keyboard using InputMethodManager class
private void hideKeyboard(EditText et) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(et.getWindowToken(), 0);
}

This is best solution which is very useful for open any DatePicker & TimePicker Dialog from EditText,
editdate.setFocusable(false);
editdate.setKeyListener(null);

Search keyword with values in arraylist in android

I am new to android development. I have created a search widget in ActionBar. Now I have to search my keyword with value stored in ArrayList. How can I get value of that searched keyword in a variable? Please give me some sample code for that.

You have to set an OnQueryTextListener to your searchView. Like this:
//listener to when the user changes the text
_searchView.setOnQueryTextListener(new OnQueryTextListener() {
boolean _first = true;
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String str) {
//do you arraylist filtering here
ArrayList<String> arrayList = new ArrayList<String>(); //your arraylist, that you will filter
for(String arrayItem:arrayList){
if(arrayItem.contains(str)){
//add this item to your new list
}
}
return true;
}
});
Then you just have to refresh your listAdapter with the new filtered array.

Try below code snippet
actionbar_serch.xml
<?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:background="#drawable/action_header"
android:gravity="center_vertical"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/edit_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Search"
android:paddingLeft="15dip"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textCursorDrawable="#null" />
</LinearLayout>
</LinearLayout>

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
item_array=new ArrayList<String>();
for(int i=0;i<10;i++)
{
item_array.add("item"+i);
}
ActionBar actionBar = getSupportActionBar();
actionBar.setCustomView(R.layout.actionbar_serch);

btn_search=(Button)findViewById(R.id.btn_search);
edit_search = (EditText) findViewById(R.id.edit_search);
edit_search.addTextChangedListener(new TextWatcher() {
#Override

{
Log.e("Search item position is=", ""+i);
break;
}
}
}
});
}
}
Hope this helps you!!!!!
If it is not working please let me know i will try to help you more.

Enabling the Edittext on selecting Item from Spinner

hello friends I am trying to enable the edittext depending upon my selection of records.The XML file is as 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 the Java Code that I am applying is as 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 I am setting the spinner where I am taking the content of the
// table per_ID having all the unique IDs and setting it to the 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 I am setting all the column names in the second spinner with the
// help of the 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 I am setting all the Items that are selected in the string in
// order to perform the 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 even when I am selecting the reg_id from spinner it is not entering the first if part as the Log.d("TESTING", "LOOOOGGGGG"); is not printed

Try this..
If you comparing String you 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();
}
== always just compares two references (for non-primitives, that is) - i.e. it tests whether the two operands refer to the same object.
However, the equals method can be overridden - so two distinct objects can still be equal
EDIT
if(parent.getItemAtPosition(pos).toString().equalsIgnoreCase("reg_id") || parent.getItemAtPosition(pos).toString().equels("first_name")){
}

You should use the .equals(String) method for string comparison (which performs a simple 'shallow' comparison) rather than the '==' comparison (which performs a 'deep' comparison - verifying if two string objects point to the same instance in memory).
Also, to toggle enabled/disabled state, you need to use the setEnabled(boolean) method. setEnabled(true) will set the edittext to be enabled and setEnabled(false) will disable the edittext.

Android Listview Search filter

I am trying to make a list view search for Android. I have found many tutorials that do just that where
a search-bar is placed at the top and if you type in the box the results get filtered.
In my app I want to click on given items after filtering has been completed, I have implemented setOnItemClickListener. The issue is that after filtering the position of each class that I want to open changes and the incorrect pages open. I was unable to find a solution....
Here is the jave code:
package com.equations.search;
import java.util.ArrayList;
import java.util.HashMap;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TextView;
public class EquationsSearch extends Activity {
// List view
private ListView lv;
// Listview Adapter
ArrayAdapter<String> adapter;
// Search EditText
EditText inputSearch;
// ArrayList for Listview
ArrayList<HashMap<String, String>> productList;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.equations_search);
// Listview Data
final String products[] = { "Dell Inspiron", "HTC One X",
"HTC Wildfire S", "HTC Sense", "HTC Sensation XE" };
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
// Adding items to listview
adapter = new ArrayAdapter<String>(this,
R.layout.equations_search_list, R.id.product_name, products);
lv.setAdapter(adapter);
/**
* Enabling Search Filter
* */
inputSearch.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence cs, int arg1, int arg2,
int arg3) {
// When user changed the Text
EquationsSearch.this.adapter.getFilter().filter(cs);
}
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
public void afterTextChange(Editable arg0) {
// TODO Auto-generated method stub
}
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// if(position == 1)
String openClass = products[position];
if (openClass.equals("HTC Wildfire S")) {
// code specific to first list item
Intent myIntent = new Intent(view.getContext(), A6262.class);
startActivityForResult(myIntent, 0);
}
}
});
}
}
and here is the xml equations_search.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<!-- Editext for Search -->
<EditText android:id="#+id/inputSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Search products.."
android:inputType="textVisiblePassword"/>
<!-- List View -->
<ListView
android:id="#+id/list_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
and equations_search_list.xml
<?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" >
<!-- Single ListItem -->
<!-- Product Name -->
<TextView android:id="#+id/product_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dip"
android:textSize="16dip"
android:textStyle="bold"/>
</LinearLayout>
Thank you in advance.

Rather than products[position], use adapter.getItem(position). When the ListView is not in filter mode, those two things will be the same. But, in filter mode, getItem() will take the filtering into account.

The ListAdapter will change the relative position of the items it currently shows due to the filtering. You should always use getItem(position) to retrieve the correct item.

close custom Dialog android

I created a custom dialog with spinner and OK button. I have populated this spinner with some items and inflated the layout.If I click OK button dialog will dismiss.
I set the spinner
spinner.performCLick();
is there is any way to get spinner selected item and to close the dialog without pressing OK button. I have tried
button.performclick();
but no use.

see my below code it may help you.

This code is work for me perfectly ok.
enjoy....

EDIT (removed previous non-suitable answer)
I'm going to assume that your issue is that using setOnItemSelectedListener is firing 'onItemSelected' on startup (thus selecting the first item in the spinner without any user input) and you don't want that.
If that is the case, try the following.
Set a class variable:
private int newSpinner = 0;
Then in the setOnItemSelectedListener:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
#Override
public void onItemSelected(AdapterView<?> parent, View view,int pos, long id) {
if (newSpinner != 0) {
// Do your code thing here
dismiss();
} else {
newSpinner++
}
}
});
