How to hide the Umano SlidingupPanel when clicking outside the panel

AndroidSlidingUpPanel
Here, I am using slidingup panel library. You can see both the panel and listview in the following screen. What i am trying to do is to hide the panel if i click outside the panel(Dim Area). Instead it is clicking on the listview in the above layout. How can i achieve this?
Here is the XML,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res/com.voucher.point.activity"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<!-- sothree:dragView="#+id/dragView" -->
<com.sothree.slidinguppanel.SlidingUpPanelLayout
xmlns:sothree="http://schemas.android.com/apk/res-auto"
android:id="#+id/sliding_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom"
app:fadeColor="#color/transparent"
sothree:panelHeight="40dip"
sothree:paralaxOffset="200dp" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/white"
android:orientation="vertical" >
<ListView
android:id="#+id/offersList"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scrollbars="none"
android:visibility="gone" >
</ListView>
</LinearLayout>
<include
android:id="#+id/bottom_menu"
android:layout_width="fill_parent"
android:layout_height="270dip"
layout="#layout/side_menu" />
</com.sothree.slidinguppanel.SlidingUpPanelLayout>
Can i do like this?

With the version 3.3.0 and later, it's possible to do that in the following way
final SlidingUpPanelLayout slidingUpPanelLayout = (SlidingUpPanelLayout) findViewById(R.id.sliding_layout);
slidingUpPanelLayout.setFadeOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
slidingUpPanelLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
});
source

I believe you have fixed your problem but for others who has same requirement I added another View on top of my map (in xml layout) and set it's touch click-ability.
So my xml file is like this:
<com.sothree.slidinguppanel.SlidingUpPanelLayout
android:id="#+id/sliding_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/booking_confirm_layout"
android:gravity="bottom"
app:umanoFadeColor="#color/black_75_percent"
app:umanoOverlay="true"
app:umanoPanelHeight="111dp"
app:umanoShadowHeight="0dp">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.gms.maps.MapView
android:id="#+id/map_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="96dp" />
<View
android:id="#+id/mapCover"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"/>
</FrameLayout>
<LinearLayout>
.
.
.
</LinearLayout>
</com.sothree.slidinguppanel.SlidingUpPanelLayout>
And in the code:
this.mMapCover = findViewById(R.id.mapCover);
this.mMapCover.setOnTouchListener(new View.OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
if (mSlidingPanel.getPanelState() != PanelState.COLLAPSED)
{
mSlidingPanel.setPanelState(PanelState.COLLAPSED);
return true;
}
return false;
}
});

//to hide when you touch overlay
mLayout.setFadeOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
});

to hide it totaly
mLayout.setFadeOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.HIDDEN);
}
});

you can add a onClickListener or onTouchListener to the outside panel and ontouch or oncick call slidingPanelLayout.expandPane(0)
findViewById(R.id.bg_panel).setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
slidingPanelLayout.expandPane(0);
return false;
}

The answered code didn't work for me. Unfortunately this event does not capture a click on part of my UI.
So for doing that, set an id for main content (first child of SlidingUpPanelLayout) and call this:
findViewById(R.id.main_content).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(slidingUpPanelLayout.getPanelState() != SlidingUpPanelLayout.PanelState.COLLAPSED){
slidingUpPanelLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
}
});

Your slidingUp panel contain whole screen then how you detect the click on outside of screen. If you are targeting it to only for "HideMenu" and "ShowMenu" then it is possible to do.
Otherwise with Full Screen SlidingUp Panel you can able to hide it by click back android button or any click event on the panel it self.
Let me know if my answer not resolve your problem.
Enjoy Coding... :)

android: How to make settings navigation like native settings app

How do I make the settings navigation for SwitchReference like Android native settings app?
Where when u click on WiFi region(not on the switch) it will navigate to a new screen:
My app only change the switch from ON to OFF and vice versa even when I'm not clicking on the switch.
I'm using PreferenceFragment and xml for the screen. And my preference is following the example from Android PreferenceFragment documentation. I develop my app on ICS 4.0 API 14.
Anyone know how to do this?
Edited:
My XML look like this:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<PreferenceCategory
android:layout="#layout/preference_category"
android:title="User Settings" >
<SwitchPreference
android:key="pref_autorun"
android:layout="#layout/preference"
android:summary="Autorun SMODE on boot"
android:title="Autorun SMODE" />
<SwitchPreference
android:key="pref_wifi_control"
android:layout="#layout/preference"
android:selectable="false"
android:summary="Controls your Wi-Fi radio automatically based on hotspot availability"
android:title="Wi-Fi Radio Control" />
</PreferenceCategory>
</PreferenceScreen>

By taking a look at the source of the stock Settings app, you can find how they did it.
Basically, they use a custom ArrayAdapter (much like you would do with a ListView) to display rows with Switch buttons. And for the second screen, they simply use the CustomView available in the ActionBar.
I wrote an article with a sample code to show how you can do it in your project. Be careful though, this can only wirk in API Level 14 or higher, so if you target older devices, keep an old style preference screen.

I see 2 questions here: 1. How to listen to preference click outside the switch area? 2. How to put a switch in the actionbar?
I'll answer question 1:
I created a new SwitchPreference class and overrode the onClick method to do nothing. This prevents the setting change when clicking outside the switch.
public class SwitchPreference extends android.preference.SwitchPreference {
#Override
protected void onClick() {
}
}
Usage (xml):
<android.util.SwitchPreference
android:key="whatever"
android:title="Whatever" />
Usage (java):
SwitchPreference switchPreference = (SwitchPreference) findPreference("whatever");
switchPreference.setOnPreferenceClickListener(new OnPreferenceClickListener() {
#Override
public boolean onPreferenceClick(Preference preference) {
DialogUtils.showToast(Preferences.this, "Clicked outside switch");
return true;
}
});
switchPreference.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
#Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
DialogUtils.showToast(Preferences.this, "Clicked inside switch and setting changed");
return true;
}
});

I gave this one a try and struggled a bit. I thought I would share my experience.
At first I tried the answer by XGouchet since it had the most up votes. The solution was fairly complicated and required using preference headers which are very cool but did not fit what I was doing. I decided the easiest thing for me to do is to wrap up my preferenceFragment in a regular fragment and make fake the switch preference with a regular view. I dug up the android source for a preference and came up with this
<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="com.lezyne.link.ui.homeScreen.settingsTab.SettingsFragment">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
</FrameLayout>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:background="#e1e1e1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/selectableItemBackground"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeight"
android:orientation="horizontal"
android:paddingRight="?android:attr/scrollbarSize">
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="6dip"
android:layout_marginLeft="15dip"
android:layout_marginRight="6dip"
android:layout_marginTop="6dip"
android:layout_weight="1">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#android:id/title"
android:layout_below="#android:id/title"
android:maxLines="4"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="?android:attr/textColorSecondary" />
</RelativeLayout>
<!-- Preference should place its actual preference widget here. -->
<RelativeLayout
android:id="#+id/widget_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="vertical"
android:paddingEnd="36dp">
<Switch
android:thumb="#drawable/switch_inner"
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true" />
<TextView
android:id="#+id/textView6"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:text="#string/Notifications"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:background="#e1e1e1" />
</LinearLayout>
The FrameLayout at the top gets a preference fragment like so
getChildFragmentManager()
.beginTransaction()
.replace(R.id.fragment_container, new SettingsPreferencesFragment(), "SettingsPreferencesFragment")
.commit();
Then I can get assign my click listeners as I would in any regular view. SettingsPreferencesFragment is just totally standard preference fragment.
This solution seemed pretty good, but then I noticed weird layout issues on tablets. I realized that I would have trouble getting this solution to look right on all devices and I needed to use a real switchPreference not a fake one.
============== Solution 2 ===============
AlikElzin-kilaka's solution was nice and simple but did not work when I tried. I tried a 2nd time to make sure that I had not just done it wrong. I kept playing around and came up with something that seems to work. He has a good point about
2 questions here: 1. How to listen to preference click outside the
switch area? 2. How to put a switch in the actionbar?
Really only question (1) is worth answering because question 2 has been answered here and other places
I realized the only way to get access to the views in a preference was to create a child class and override onBind. So I came up with this child class of SwitchPreference that creates separate click handlers for the switch as the entire view. Its still a hack though.
public class MySwitchPreference extends SwitchPreference {
public MySwitchPreference(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public MySwitchPreference(Context context, AttributeSet attrs) {
super(context, attrs);
getView(null,null);
}
public MySwitchPreference(Context context) {
super(context);
}
public interface SwitchClickListener{
public void onSwitchClicked(boolean checked);
public void onPreferenceClicked();
}
private SwitchClickListener listener = null;
public void setSwitchClickListener(SwitchClickListener listener){
this.listener = listener;
}
public Switch findSwitchWidget(View view){
if (view instanceof Switch){
return (Switch)view;
}
if (view instanceof ViewGroup){
ViewGroup viewGroup = (ViewGroup)view;
for (int i = 0; i < viewGroup.getChildCount();i++){
View child = viewGroup.getChildAt(i);
if (child instanceof ViewGroup){
Switch result = findSwitchWidget(child);
if (result!=null) return result;
}
if (child instanceof Switch){
return (Switch)child;
}
}
}
return null;
}
protected void onBindView (View view){
super.onBindView(view);
final Switch switchView = findSwitchWidget(view);
if (switchView!=null){
switchView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (listener!=null) listener.onSwitchClicked(switchView.isChecked());
}
});
switchView.setFocusable(true);
switchView.setEnabled(true);
}
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (listener!=null) listener.onPreferenceClicked();
}
});
}
}
It uses the recursive function findSwitchWidget to walk the tree until it finds a Switch. I would have rather write code like this:
Switch switchView = view.findViewById(android.R.id.switchView);
but there does not seem to be a way to get to that internal id value that I know of. Anyhow once we have the actual switch we can assign listeners to it and the container view. The switch preference won't update automatically so its necessary to save the preference yourself.
MySwitchPreference switchPreference = (MySwitchPreference) findPreference("whatever");
switchPreference.setSwitchClickListener(new MySwitchPreference.SwitchClickListener() {
#Override
public void onSwitchClicked(boolean checked) {
//Save the preference value here
}
#Override
public void onPreferenceClicked() {
//Launch the new preference screen or activity here
}
});
Hopefully this 2nd hack wont come back to bite me.
Any one see any potential pitfalls of this method?
I also put a slightly improved version of the code on github https://gist.github.com/marchold/45e22839eb94aa14dfb5

Strange behaviour when using WebView and RelativeLayout in fullscreen

EDIT:
Here's the video showing the problem: www.youtube.com/watch?v=5ZZsuMH5T9k I'm really stuck here :/
--
I have an activity which consists of a webview and a button at the bottom. I set the window of the activity to fullscreen using this code in onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
InstaFetchApplication.applyCurrentTheme(this);
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
requestWindowFeature(Window.FEATURE_PROGRESS);
if (UserPreferences.getIsFullScreenReadingEnabled(this)) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
// this just do this: window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
ActivityUtils.toggleFullScreen(this, true);
}
setContentView(R.layout.view_article);
// ...
}
The problem is that most of the time the webview seems to "push" the button off the screen. Here's the screenshot:
(larger version)
What I would expect to see (and sometimes I do) is here:
(larger version)
Here's the layout I'm using (note that in my app the top layout has to be a RelativeLayout):
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_test"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="#+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Click me!"
/>
<WebView
android:id="#+id/web_view"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/button"
/>
</RelativeLayout>
I also noticed that if you turn off all animations on the device using system settings, the issue is gone (though there's this glitch when the whole view has a top margin and then it jumps back in the correct position).
Did anyone encounter similar problem and know how to fix it?

Finally I found the answer. Adding WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS flag to the window solved my problem.
See this post: flag_fullscreen + windowNoTitle == button focus bug.

I just added a button to the Hello WebView tutorial, and everything seems to look right. Then I converted main.xml from LinearLayout to RelativeLayout, and everything still seems to look right. I think you are making things too complicated. :-) Try removing most of that initialization code from onCreate() and just specify it in the XML.
Here is my project.

mWebView = (WebView) findViewById(R.id.webview);
mWebView.setWebViewClient(new HelloWebViewClient());
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
private class HelloWebViewClient extends WebViewClient {
#Override

view.loadUrl(url);
return true;
}
}
}

</resources>

Try to align the web view to the parent top, and align the button to the parent bottom and to be below the web view. I have found times when, for no real reason, the elements don't quite line up correctly if they are not all strung together in a linear sequence either anchored at the top or at the bottom of the screen.
I presume that you are not overriding the onMeasure() method and changing the measured height of the button. I've created numerous (too many) bugs during development of my apps by miscalculating the height of an element during the layout phase and have spent hours struggling with debugging the layout definition code only to find that it was fine, but the height calculation was feeding invalid data into the layout's rendering phase.

Unless the RelativeLayout is absolutely necessary, You could change to a LinearLayout:
<?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">
<WebView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="I'm a button"/>
</LinearLayout>
It should give a better result.

To hide the title bar I use:
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Tested on a Galaxy S 2 (Android 2.3.3) and Huawei U8180 X1 (Android 2.2.2) and worked fine with your relative layout.
From the screenshot I have the impression that the problem lies rather with the incomplete progress indicator you requested. The fact that the problem disappears when turning off the animations also supports this theory.

You may try this. The top layout is still RelativeLayout, the only difference with yours is the LinearLayout is wrapping up everything:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_test"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="1">
<WebView
android:id="#+id/web_view"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight=".90" />
</LinearLayout>
</RelativeLayout>
In the LinearLayout, WebView occupies 90% of entire window(and parent) and the button remaining 10%. The height is set to 0px for both, so the weight can do the work for both of them. The cost for the parsing this xml is insignificant.
And in Java code I did:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
requestWindowFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
LinearLayout mLinearLayout = (LinearLayout)findViewById(R.id.ll);
Button mButton = new Button(this);
LinearLayout.LayoutParams mParams = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, 0, 0.10f);
mButton.setText("Click me!");
mButton.setLayoutParams(mParams);
mLinearLayout.addView(mButton);
mLinearLayout.invalidate();
}

below code might help you,
webView = (WebView) findViewById(R.id.webview1);
webView.setInitialScale(100);
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
view.scrollTo(0, 0);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadDataWithBaseURL(null, yourdata, "text/html", "utf-8", null);
// view.loadUrl(url);
return true;
}
});
webView.setWebChromeClient(new WebChromeClient() {
#Override
public void onProgressChanged(WebView view, int newProgress) {
try {
//your stuff
} catch (Throwable e) {
e.printStackTrace();
}
}
}

Android: problem creating user form from a menu

I'm very new to programming in Android, but have been struggling all day with a problem and would appreciate your help.
I'm trying to create a form to get user information (essentially a new contact) which is accessed from the menu. When I click the button to create the new form, I get the following error:
"Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy#626fd5e0"
This is my code:
The menu xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/search"
android:title="#string/settings_search"
android:alphabeticShortcut="#string/settings_shortcut_search" />
<item android:id="#+id/new_contact"
android:title="#string/settings_new"
android:alphabeticShortcut="#string/settings_shortcut_new" />
</menu>
The code for calling the new activity:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.new_contact:
//activities to create a new account
//startActivity(new Intent(this, Prefs.class));
Intent i = new Intent(MainActivity.this, NewContact.class);
startActivity(i);
//addSaver("String");
return true;
case R.id.search:
return true;
// More items go here (if any) ...
}
return false;
}
The view for the new contact activity:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">"
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_gravity="top">
<TextView
android:id="#+id/text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="This is a test\nsecond line\n"/>
<Button
android:id="#+id/new_contact_button"
android:layout_height="wrap_content"
android:text="#string/submit" />
</LinearLayout>
</ScrollView>
And the code for the new activity:
public class NewContact extends Activity implements OnClickListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_contact);
// Set up click listeners for all the buttons
View newContactButton = findViewById(R.id.new_contact_button);
newContactButton.setOnClickListener(this);
}
Bizarrely if I comment out the button from the class and from the xml then it works correctly and opens up the new activity (but of course I can't do anything with that activity).

In your button xml code, you are missing
android:layout_width="wrap_content"
add that and give it a shot.
