Adding a ListView causes the Android App to crash - android

I have a problem which seems to weird.
The Android application I created is running fine, but when I added a "ListView" element in my layout.xml file.
and I still haven't used the ListView in my java class the application refuses to startup.
It simply craches and gives me this Msg : The application Client (process com.example) has stopped unexpectedly. Please try again.
This is my layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="#+id/view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/filename"/>
<ListView android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"
/>
<EditText
android:id="#+id/input"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
/>
<Button
android:id="#+id/connect"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Connect"
android:onClick="Connect"
/>
<Button
android:id="#+id/download"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Download"
android:onClick="Download"
/>
<Button
android:id="#+id/delete"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="List"
android:onClick="List"
/>
</LinearLayout>
Note: I'm testing on an Android device and not the emulator
Here is a Screenshot of the error I get in logcat: http://img852.imageshack.us/i/screenshotgg.png/
And finally found the sill mistake which caused it not to work
I declared 2 widgets with the same id.
Thnx alot in advance.

You need to close the LinearLayout. Add </LinearLayout> to the end of the xml.
Edit: I see that you've uploaded the log. The problem is in your onCreate-method on line 42. Please post this method.

//try this it may help you
Add this into your manifest file
<uses-library android:name="com.google.android.maps" />
I had the same problem when I try to build a simple app, following the Android MapView tutorial.
The app showed this exception in AVD for the file file main.xml:
Failed to find style 'mapViewStyle' in current theme
At last I found that there is a mistake in file AndroidManifest.xml:
The element should be a child of the element, not immediately within .
Hope this was any help to you.

Adding android:id to xml breaks entire app

I have this XML file:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:text="Disable Filter" android:background="#drawable/buttons" style="#style/ButtonText" android:layout_weight="25" />
<ImageView android:id="#+id/imageFilter" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="75" />
<HorizontalScrollView android:layout_width="fill_parent" android:layout_height="wrap_content">
<LinearLayout android:id="#+id/horizontal" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent">
</LinearLayout>
</HorizontalScrollView>
</LinearLayout>
As soon as I add android:id="#+id/btnFilterPreview" to the Button my app stops working. Why is that?
In Netbeans to solve the issue, Right click on the Project and and chose: Clean and Build
Clean Build your project so that all id is regenerate and application will find reference of new ids.
This is a Same code of you . Running Perfect Without any changes.
I had just Clean & Re-Build Project Nothing else .
Try it.
<Button
android:id="#+id/btnFilterPreview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_weight="25"
android:background="#drawable/ic_action_search"
android:text="Disable Filter" />
<ImageView
android:id="#+id/imageFilter"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="75" />
<LinearLayout
android:id="#+id/horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="25"
android:orientation="horizontal" >
</LinearLayout>
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</HorizontalScrollView>
It may also be caused Android automatically adds android.R in its header file remove it
and then Build Project Again
Besides Clean and Build, make sure you do not have duplicate IDs.
Say you have another ImageView with the same ID, it could crash when some code like
(Button)findViewById(R.id.btnFilterPreview)
is executed.

4.1: XML Layout LinkedHashMap error

<?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">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="10dp"
android:paddingRight="10dp">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Some Text"
android:layout_margin="5dp"
android:textSize="22sp"
/>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="#android:color/black"
/>
<EditText
android:id="#+id/edit_firstname"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="text"
/>
</LinearLayout>
</LinearLayout>
I have this XML Layout above, everything is working fine in 4.0.3, but when I apply it to 4.1, it produces this error below. When I removed EditText layout is fine.
Dont know the reason but placing android:inputType="textNoSuggestions" in EditText is working.
It's an issue right now It doesn’t come from ADT 20 but from the rendering library of Jelly Bean. So We need to wait for an update of JB to have a fix.
But as a workaround, we are able to solve this by disabling the SpellChecker.
java.lang.NoSuchMethodError: java.util.LinkedHashMap.eldest()Ljava/util/Map$Entry;
at android.util.LruCache.trimToSize(LruCache.java:206)
at android.util.LruCache.evictAll(LruCache.java:306)
at android.widget.SpellChecker.resetSession(SpellChecker.java:141)
at android.widget.SpellChecker.setLocale(SpellChecker.java:147)
So add android:inputType="textNoSuggestions" to your EditText and you will get this problem resolved.

Android Java Coding Errors, Need Assistance

I am a beginner coder trying to learn how to make android apps. I am using these tutorials and I guess I have ran into an error.
Here is my text.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="25dp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/etCommands"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Type a command"
android:password="true" />
<LinearLayout
android:weightSum="100"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
<Button
android:layout_weight="20"
android:id="#+id/Bresults"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Button" />
<ToggleButton
android:layout_weight="80"
android:id="#+id/tbPassword"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="ToggleButton"
android:checked="true" />
</LinearLayout>
<TextView
android:id="#+id/tvresults"
android:paddingBottom="10dp"
android:checked="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="invalid" />
</LinearLayout>
I am getting an error next to where it says button. The error says:
Multiple annotations found at this line: - Element type "LinearLayout" must be followed by either attribute specifications, ">" or "/>". - error:error parsing XML:not well-formed (invalid token)"
You need to close the tag on your second Linear Layout >
<LinearLayout
android:weightSum="100"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"> <!-- here -->
The colorcoding in your post already highlights the issue. You forgot the > after the LinearLayout opening tag.
The IDE is complaining that your xml is not well-formed. If the IDE's errors are not clear enough, you try an online validator such as http://www.xmlvalidation.com/ .

Error in displaying nested LinearLayout

I am using nested linearlayout in my xml file.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:text="left"
android:layout_weight="1"
android:layout_gravity="left"
android:id="#+id/previous"></Button>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:id="#+id/date"
android:textColor="#505050"
/>
<Button android:text="right"
android:layout_weight="1"
android:layout_gravity="right"
android:id="#+id/next"></Button>
</LinearLayout>
.........
........
</LinearLayout>
My application doesnt start , i get an error message saying the process stopped unexpectedly. Though it works without the inner Linearlayout.
Any ideas why?
Thanks
You should definitely post the stack trace when you have exceptions thrown and you want help, but in this case you seem to be missing the layout_width and layout_height attributes for your buttons.
