分享下靜態截圖的功能程式碼：

public class ScreenShot {

    // 獲取指定Activity的截圖，儲存到png檔案

    static Bitmap takeScreenShot(Activity activity) {

    	Log.i("TAG","tackScreenShot");
        // View是你須要截圖的View
        View view = activity.getWindow().getDecorView();
        view.setDrawingCacheEnabled(true);
        view.buildDrawingCache();
        Bitmap b1 = view.getDrawingCache();

        // 獲取狀況欄高度
        Rect frame = new Rect();
        activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
        int statusBarHeight = frame.top;
        Log.i("TAG", "statusBarHeight = " + statusBarHeight);

        // 獲取螢幕長和高
        int width = activity.getWindowManager().getDefaultDisplay().getWidth();
        int height = activity.getWindowManager().getDefaultDisplay()
                .getHeight();

        // 去掉題目欄
        // Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455);
        Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height
                - statusBarHeight);
        view.destroyDrawingCache();
        return b;
    }

    // 儲存到sdcard
    private static void savePic(Bitmap b, String strFileName) {

        FileOutputStream fos = null;
        try {
        	Log.i("TAG","start savePic");
            fos = new FileOutputStream(strFileName);
            Log.i("TAG","strFileName = " + strFileName);
            if (null != fos) {
                b.compress(Bitmap.CompressFormat.PNG, 90, fos);
                fos.flush();
                fos.close();
                Log.i("TAG","save pic");
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }


    public static void shoot(Activity a,String b) {
        //ScreenShot.savePic(ScreenShot.takeScreenShot(a), "sdcard/xx.png");
    	Log.i("TAG","shot");
    	Bitmap bitmap = ScreenShot.takeScreenShot(a);
		ScreenShot.savePic(bitmap, b);
    }
}
 

以下是對正在播放的視訊進行截圖的功能程式碼：

	private Bitmap createVideoThumbnail(String filePath) {
		Bitmap bitmap = null;
		android.media.MediaMetadataRetriever retriever = new android.media.MediaMetadataRetriever();
		try {// MODE_CAPTURE_FRAME_ONLY
//			retriever
//					.setMode(android.media.MediaMetadataRetriever.MODE_CAPTURE_FRAME_ONLY);
//			retriever.setMode(MediaMetadataRetriever.MODE_CAPTURE_FRAME_ONLY);
			retriever.setDataSource(filePath);
//			bitmap = retriever.captureFrame();
			String timeString = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
			long time = Long.parseLong(timeString) * 1000;
			Log.i("TAG","time = " + time);
			bitmap = retriever.getFrameAtTime(time*31/160); //按視訊長度比例選擇幀
		} catch (IllegalArgumentException ex) {
			// Assume this is a corrupt video file
		} catch (RuntimeException ex) {
			// Assume this is a corrupt video file.
		} finally {
			try {
				retriever.release();
			} catch (RuntimeException ex) {
				// Ignore failures while cleaning up.
			}
		}
		return bitmap;
	}
