Disable or enable it before setting the adapter.

    yourSpinner.setEnabled(false);   
    yourSpinner.setClickable(false);  
    yourSpinner.setAdapter(typeAdapter);

It&#39;s not possible to enable/disable a Spinner in XML (yet).
To do so you have to do it in code.

Here&#39;s an example:

    Spinner spinner = (Spinner) findViewById(R.id.mySpinner);
    spinner.setEnabled(false);

you can set `android:clickable=&quot;false&quot;` in the `xml` to disable the `spinner` for click `event`.

You can set this in the Java code itself, instead of in the `XML`, because the `Spinner` should implement `setEnabled(boolean)` from `View`.

How to get the background color code of an element in hex?

In Objective C I&#39;ve been using the following code to hash a string:

    -(NSString *) sha1:(NSString*)stringToHash {	
        const char *cStr = [stringToHash UTF8String];
        unsigned char result[20];
        CC_SHA1( cStr, strlen(cStr), result );
        return [NSString stringWithFormat:@&quot;%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X&quot;,
			result[0], result[1], result[2], result[3], 
			result[4], result[5], result[6], result[7],
			result[8], result[9], result[10], result[11],
			result[12], result[13], result[14], result[15],
			result[16], result[17], result[18], result[19]
			];	
    }

Now I need the same for Android but can&#39;t find out how to do it. I&#39;ve been looking for example at this: https://stackoverflow.com/questions/5757024/make-sha1-encryption-on-android
 but that doesn&#39;t give me the same result as on iPhone. Can anyone point me in the right direction?

How to SHA1 hash a string in Android?

I&#39;m having problems when using `android:enabled=&quot;false&quot;`, it&#39;s not **disabling** the **component** in the case it&#39;s a `spinner`. Don&#39;t know if it&#39;s relevant, but it belongs to a layout that&#39;s part of a `viewflipper`.

Any hints or workarounds ?

Thanks

I need to implement SQLite in my application. I followed this tutorial..
[Creating and using databases in Android one][1]

Everything is working fine. I inserted 1 row with 5 columns.
Now I want to update value of 1 column only and others will be remain same.

There is one update method in tutorial but it needs all the parameters, however I want to update only one column.

Android SQLite: Update Statement

I want to write a module where on a click of a button the camera opens and I can click and capture an image.  If I don&#39;t like the image I can delete it and click one more image and then select the image and it should return back and display that image in the activity.

I want to force the main layout resource view to redraw / refresh, in say the Activity.onResume() method. How can I do this ? 

By main layout view, I mean the one (&#39;R.layout.mainscreen&#39; below) that is called in my Activity.onCreate(), like this:-

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainscreen);
    }

I have a worker thread that creates a runnable object and calls runOnUiThread on it, because it deals with Views and controls. I&#39;d like to use the result of the work of the runnable object right away. How do I wait for it to finish? It doesn&#39;t bother me if it&#39;s blocking.

I want to set the map view zoomed to 1km radius but cant figure out how?

The doc says that the zoom level 1 will map earths equator to 256 pixels. So how do I calculate which zoom level I need to set so that the map view shows area in 1KM radius?

**UPDATE:**  
After reading a few blog posts I wrote the following code:

    private int calculateZoomLevel() {
    	double equatorLength = 6378140; // in meters
    	double widthInPixels = screenWidth;
    	double metersPerPixel = equatorLength / 256;
    	int zoomLevel = 1;
    	while ((metersPerPixel * widthInPixels) &gt; 2000) {
    	    metersPerPixel /= 2;
    	    ++zoomLevel;
    	}
    	Log.i(&quot;ADNAN&quot;, &quot;zoom level = &quot;+zoomLevel);
    	return zoomLevel;
    }
The idea is that first I calculate **Meters per pixel** in the zoom level 1, which according to google shows equator of earth using 256 pixels. Now every subsequent zoom level magnifies by a level of 2 so I half the meters per pixel for every zoom level. I do this until I have a zoom level where **meters per pixel** multiplied by the **screen width** gives me less than 2000 i.e 2 Km across.

But I dont think that the zoom level I am getting is showing the map of 2Km radius. Can some one tell me what I am doing wrong here?

I&#39;m trying to change the text color of the single item that is displayed in the spinner button after you select an item from the dropdown. I&#39;ve been perusing the themes.xml and styles.xml in the Android SDK for an hour now, and I can&#39;t seem to find where the Spinner is getting the color value from.

To clarify, I&#39;m NOT trying to change the color of a dropdown item, I&#39;m trying to change the color of the spinner&#39;s displayed text when there is no dropdown. I guess you could call it the spinner&#39;s &#39;button&#39; text.

Android: Where is the Spinner widget&#39;s text color attribute hiding?

I want to bring up a spinner dialog when the user taps a menu item to allow the user to select an item.

Do I need a separate dialog for this or can I use Spinner directly? I see [this link,][1] mentions a MODE_DIALOG option but it doesn&#39;t seem to be defined anymore. AlertDialog may be OK but all the options say &quot;clicking on an item in the list will not dismiss the dialog&quot; which is what I want. Any suggestion?

Ideally, the code would be similar to the case where the spinner is shown on the screen:

    ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(activity,
         android.R.layout.simple_spinner_item, items);			    
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    myspinner.setAdapter(adapter);	
    // myspinner.showAsDialog() &lt;-- what i want

How do I create an Android Spinner as a popup?

The goal is to display the information that the application is working. So I&#39;m looking for an intelligent implementation sample of a loading spinner using WPF / MVVM.


WPF loading spinner

Is there anyway of making a hint for a spinner similar to hint that is provided for edit text fields. I know you can use a prompt that gives you a title bar but still leaves the initial spinner field blank until you click into the spinner. I currently have a crude way of setting a dummy field as the first part of the spinner array which is the question and then have a check at the end to make sure the spinner doesn&#39;t equal the question string. Is there any cleaner / better way of doing this?

Thanks!

Is it possibile to set hint Spinner in Android

In my Android application, I am using spinner, and I have loaded data from the SQLite database into the spinner, and it&#39;s working properly. Here is the code for that.

    Spinner spinner = (Spinner) this.findViewById(R.id.spinner1);
    List&lt;String&gt; list = new ArrayList&lt;String&gt;();
    ArrayAdapter&lt;String&gt; dataAdapter = new ArrayAdapter&lt;String&gt;  (this,android.R.layout.simple_spinner_item, list);
    cursor.moveToFirst();

    list.add(&quot;All Lists&quot;);

    if (cursor.getCount() &gt; 0) {
        for (int i = 0; i &lt; cursor.getCount(); i++) {
            keyList[i] = cursor.getString(cursor.getColumnIndex(AndroidOpenDbHelper.KEYWORD));
            list.add(keyList[i]);
            cursor.moveToNext();
        }
    }
    Database.close();
    cursor.close();
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(dataAdapter);

Now I want to change the text color and text size of spinner data. I have used following XML lines to my spinner tag on my XML file, but it is not working.

    android:textColor=&quot;@android:color/white&quot;
    android:textSize=&quot;11dp&quot;

How can I change the text color and text size of my spinner?
