Sencha Touch android keypad hiding textarea

`
constructor: function() {
this.adjustHeight = Ext.Function.createBuffered(function(textarea) {
var textAreaEl = textarea.getComponent().input;
if (textAreaEl) {
textAreaEl.dom.style.height = 'auto';
var iNewHeight = textAreaEl.dom.scrollHeight;
if (iNewHeight > 0) {
textAreaEl.dom.style.height = textAreaEl.dom.scrollHeight + "px";
}
}
},200,this);
this.callParent(arguments);
}
I want the textarea focused with full content visible . But text area hiding with keypad

Try to use the onBeforeFocus event with scrolling:
scrollableView.scrollTo(textfield.element.getXY()[0],textfield.element.getXY()[1]);
And now you might want to do this to all textfields and textareafields, so that the user gets the same on all items.
Make sure, that the effect is either earlier than the keypad animation or delay it with about 175ms.
Ext.defer(function() {###your code goes here###}, 175, this);

Show keyboard in Libgdx

I am trying to show the keyboard on a android device when a textfield is clicked in LibGdx. But as far as I can see have to detect when the textfield is clicked manually and then show the keyboard by calling Gdx.input.setOnscreenKeyboardVisible(true)?
This is the code I have so far:
textfield= new TextField("", skin);
textfield.setSize(300, 50);
textfield.setPosition((SCREEN.WIDTH/2) - textfield.getWidth()/2, 0);
//Gdx.input.setOnscreenKeyboardVisible(true);
//Gdx.input.getTextInput(this, "SOME TITLE" "TEXT");
textfield.setTextFieldListener(new TextFieldListener()
{
#Override
public void keyTyped(TextField textField, char key)
{
if (key == '\n')
{
textField.getOnscreenKeyboard().show(false);
}
}
});
Thanks for any help!

Moved from comment on original post (and edited to be more answer-like):
The keyboard is normally shown automatically when a text field gains focus or is touched. You shouldn't have to do it manually. This requires the stage to be registered as the input processor via this call:
Gdx.input.setInputProcessor(stage);

jQuery Mobile fixed footer is moving when the keyboard appears

I have designed an app using Phonegap and jQuery Mobile. The fixed footer works properly until I click on a dropdown or text field, which causes the footer to either disappear from view (Android 4.0) or move to the middle of the view (Android 2.2 Galaxy Tab). Any suggestions?
Phonegap Version: Cordova 2.1.0
jQuery Mobile Version: 1.2.0
Here is my code:
<div data-role="footer" class="nav-mobilyzer" data-tap-toggle="false" data-position="fixed">
<div data-role="navbar" class="nav-mobilyzer" data-grid="d">
<h1>footer</h1>
</div>
</div>

I had the problem in some devices the footer displayed and in others it didn't. I found this worked for me:
var initialScreenSize = window.innerHeight;
window.addEventListener("resize", function() {
if(window.innerHeight < initialScreenSize){
$("[data-role=footer]").hide();
}
else{
$("[data-role=footer]").show();
}
});
EDIT:
But what about orientation changes?
var portraitScreenHeight;
var landscapeScreenHeight;
if(window.orientation === 0 || window.orientation === 180){
portraitScreenHeight = $(window).height();
landscapeScreenHeight = $(window).width();
}
else{
portraitScreenHeight = $(window).width();
landscapeScreenHeight = $(window).height();
}
var tolerance = 25;
$(window).bind('resize', function(){
if((window.orientation === 0 || window.orientation === 180) &&
((window.innerHeight + tolerance) < portraitScreenHeight)){
// keyboard visible in portrait
}
else if((window.innerHeight + tolerance) < landscapeScreenHeight){
// keyboard visible in landscape
}
else{
// keyboard NOT visible
}
});
The tolerance accounts for the inexact calculation of landscape height with portrait width and vis-versa.

Okay, this thread is as old as the internet at this point, but the answer above didn't seem to do the job for me.
The best way I found was to bind a method to the jquery .blur() event, and then call fixedtoolbar() methods in a very specific order, i.e.
var that = this;
$(':input').blur(function(){
that.onFocusLoss();
});
......
onFocusLoss : function() {
try {
$("[data-position='fixed']").fixedtoolbar();
$("[data-position='fixed']").fixedtoolbar('destroy');
$("[data-position='fixed']").fixedtoolbar();
console.log('bam');
} catch(e) {
console.log(e);
}
},

The keyboard is opened when we have the focus on an input so:
// hide the footer when input is active
$("input").blur(function() {
$("[data-role=footer]").show();
});
$("input").focus(function() {
$("[data-role=footer]").hide();
});

You can also detect when the keyboard shows and when it hides and show or hide your footer accordingly:
document.addEventListener("showkeyboard", function(){ $("[data-role=footer]").hide();}, false);
document.addEventListener("hidekeyboard", function(){ $("[data-role=footer]").show();}, false);

Try data-hide-during-focus="" and set it to an empty string.

My solution uses another JQUERY attribute on the div footer. Adding data-fullscreen="true" to that div was all I needed. I know that this fix might not have been available until recently, but I am using jqm 1.3.2 and jq 1.9. I thought I would post this solution just in case it helps someone. Good luck. :)

Android scroll bar in phonegap application?

I have a problem in android phonegap mobile website application, I applied scroll bar in my application, it is working good in PC but when i test in android device(mobile phone) scroll bar not enable.

personally I don't like iscroll.. had many problems using it so I discovered another solution... you can try this:
1.) set your DIV overflow to auto (or scroll) and set its height.. e.g.
<div id="wrapper" style="overflow:auto; height: 200px">...content...</div>
(I usually calculate height with javascript based on user's screen size.. I never set just a fixed height for all devices, this is just for the purpose of this "demo")
2.) add this javascript:
<script>
function isTouchDevice(){
try{
document.createEvent("TouchEvent");
return true;
}catch(e){
return false;
}
}
function touchScroll(id){
if(isTouchDevice()){ //if touch events exist...
var el=document.getElementById(id);
var scrollStartPos=0;
document.getElementById(id).addEventListener("touchstart", function(event) {
scrollStartPos=this.scrollTop+event.touches[0].pageY;
event.preventDefault();
},false);
document.getElementById(id).addEventListener("touchmove", function(event) {
this.scrollTop=scrollStartPos-event.touches[0].pageY;
event.preventDefault();
},false);
}
}
</script>
3.) call it on page load.. if you use jQuery:
$(document).ready(function() {
touchScroll("wrapper");
});
4.) if you want your scrollbars to be visible, just define following CSS rules:
::-webkit-scrollbar {
width: 10px;
}
::-webkit-scrollbar-track {
border-radius: 10px;
}
::-webkit-scrollbar-thumb {
border-radius: 10px;
background-color: #000;
}

Use this PhoneGap link
http://phonegap.pbworks.com/w/page/22863184/Hide%20the%20scrollbar%20in%20Android
this works in Android ,PhoneGap Applications for vertical and Horizontal Scroll

Code look Like this
public class MyActivity extends DroidGap {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/index.html");
// Display vertical scrollbar and hide horizontal scrollBar
super.appView.setVerticalScrollBarEnabled(true);
super.appView.setHorizontalScrollBarEnabled(false);
// set scrollbar style
super.appView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
}
}

Stopping event listener of tableviewrow in Titanium

when the user click on the tableviewrow, alert box 'row' will occur. And inside the tableviewrow, it contains another view that contains a image view. An alert box 'label' will popout when user click on the image. Now the problem is when user click on the image, not only the alert box 'label' will popup, but the alert box 'row' too. How can I avoid the alert box 'row' from popping out when user click on the image? The alert box 'row' appear when user click on the tableviewrow other than the image. Thanks..
var row = Titanium.UI.createTableViewRow({
className:'rowclass',
});
var u_image = Titanium.UI.createImageView({
image: 'image.jpg',
top:10,
left:4,
height:36,
width:36,
});
row.add(u_image);
RegData.push(row);
u_image.addEventListener('click', function(e){
alert('label');
});
row.addEventListener('click', function(e){
alert('row');
});
Ti 1.6, Android 2.2

create your image view with an id
var u_image = Titanium.UI.createImageView({
image: 'image.jpg',
id: "image_view",
top:10,
left:4,
height:36,
width:36,
});
put your listener on the whole table and not just specific elements
myTable.addEventListener('click', function(e){
if(e.source.id == "image_view") {
alert('image_view');
} else {
alert('row');
}
});

Check to make sure you aren't clicking on the image inside of the row first before alerting.
row.addEventListener('click', function(e){
if(e.source != "[object TiUIImageView]") {
alert('row');
}
});
