All Implemented Interfaces:

public class IcsProgressBar
extends android.view.View

Visual indicator of progress in some operation. Displays a bar to the user representing how far the operation has progressed; the application can change the amount of progress (modifying the length of the bar) as it moves forward. There is also a secondary progress displayable on a progress bar which is useful for displaying intermediate progress, such as the buffer level during a streaming playback progress bar.

A progress bar can also be made indeterminate. In indeterminate mode, the progress bar shows a cyclic animation without an indication of progress. This mode is used by applications when the length of the task is unknown. The indeterminate progress bar can be either a spinning wheel or a horizontal bar.

The following code example shows how a progress bar can be used from a worker thread to update the user interface to notify the user of progress:

 public class MyActivity extends Activity {
     private static final int PROGRESS = 0x1;

     private ProgressBar mProgress;
     private int mProgressStatus = 0;

     private Handler mHandler = new Handler();

     protected void onCreate(Bundle icicle) {
         super.onCreate(icicle);

         setContentView(R.layout.progressbar_activity);

         mProgress = (ProgressBar) findViewById(R.id.progress_bar);

         // Start lengthy operation in a background thread
         new Thread(new Runnable() {
             public void run() {
                 while (mProgressStatus < 100) {
                     mProgressStatus = doWork();

                     // Update the progress bar
                     mHandler.post(new Runnable() {
                         public void run() {
                             mProgress.setProgress(mProgressStatus);
                         }
                     });
                 }
             }
         }).start();
     }
 }

To add a progress bar to a layout file, you can use the <ProgressBar> element. By default, the progress bar is a spinning wheel (an indeterminate indicator). To change to a horizontal progress bar, apply the Widget.ProgressBar.Horizontal style, like so:

 <ProgressBar
     style="@android:style/Widget.ProgressBar.Horizontal"
     ... />

If you will use the progress bar to show real progress, you must use the horizontal bar. You can then increment the progress with incrementProgressBy() or setProgress(). By default, the progress bar is full when it reaches 100. If necessary, you can adjust the maximum value (the value for a full bar) using the android:max attribute. Other attributes available are listed below.

Another common style to apply to the progress bar is Widget.ProgressBar.Small, which shows a smaller version of the spinning wheel—useful when waiting for content to load. For example, you can insert this kind of progress bar into your default layout for a view that will be populated by some content fetched from the Internet—the spinning wheel appears immediately and when your application receives the content, it replaces the progress bar with the loaded content. For example:

 <LinearLayout
     android:orientation="horizontal"
     ... >
     <ProgressBar
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         style="@android:style/Widget.ProgressBar.Small"
         android:layout_marginRight="5dp" />
     <TextView
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="@string/loading" />
 </LinearLayout>

Other progress bar styles provided by the system include:

• Widget.ProgressBar.Horizontal
• Widget.ProgressBar.Small
• Widget.ProgressBar.Large
• Widget.ProgressBar.Inverse
• Widget.ProgressBar.Small.Inverse
• Widget.ProgressBar.Large.Inverse

The "inverse" styles provide an inverse color scheme for the spinner, which may be necessary if your application uses a light colored theme (a white background).

Constructor Detail

IcsProgressBar

public IcsProgressBar(android.content.Context context)

Create a new progress bar with range 0...100 and initial progress of 0.

Parameters:

context - the application environment

IcsProgressBar

public IcsProgressBar(android.content.Context context,
              android.util.AttributeSet attrs)

IcsProgressBar

public IcsProgressBar(android.content.Context context,
              android.util.AttributeSet attrs,
              int defStyle)

IcsProgressBar

public IcsProgressBar(android.content.Context context,

              int defStyle,
              int styleRes)

Method Detail

isIndeterminate

public boolean isIndeterminate()

Indicate whether this progress bar is in indeterminate mode.

Returns:

true if the progress bar is in indeterminate mode

setIndeterminate

public void setIndeterminate(boolean indeterminate)

Change the indeterminate mode for this progress bar. In indeterminate mode, the progress is ignored and the progress bar shows an infinite animation instead.

If this progress bar's style only supports indeterminate mode (such as the circular progress bars), then this will be ignored.

Parameters:

indeterminate - true to enable the indeterminate mode

getIndeterminateDrawable

public android.graphics.drawable.Drawable getIndeterminateDrawable()

Get the drawable used to draw the progress bar in indeterminate mode.

Returns:

a Drawable instance

See Also:

setIndeterminateDrawable(android.graphics.drawable.Drawable), setIndeterminate(boolean)

setIndeterminateDrawable

public void setIndeterminateDrawable(android.graphics.drawable.Drawable d)

Define the drawable used to draw the progress bar in indeterminate mode.

Parameters:

d - the new drawable

See Also:

getIndeterminateDrawable(), setIndeterminate(boolean)

getProgressDrawable

public android.graphics.drawable.Drawable getProgressDrawable()

Get the drawable used to draw the progress bar in progress mode.

Returns:

a Drawable instance

See Also:

setProgressDrawable(android.graphics.drawable.Drawable), setIndeterminate(boolean)

setProgressDrawable

public void setProgressDrawable(android.graphics.drawable.Drawable d)

Define the drawable used to draw the progress bar in progress mode.

Parameters:

d - the new drawable

setProgress

public void setProgress(int progress)

Set the current progress to the specified value. Does not do anything if the progress bar is in indeterminate mode.

getProgress

public int getProgress()

Get the progress bar's current level of progress. Return 0 when the progress bar is in indeterminate mode.

Returns:

the current progress, between 0 and getMax()

See Also:
