分享下静态截图的功能代码：
public class ScreenShot {
// 获取指定Activity的截屏，保存到png文件
static Bitmap takeScreenShot(Activity activity) {
Log.i(&TAG&,&tackScreenShot&);
// View是你须要截图的View
View view = activity.getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap b1 = view.getDrawingCache();
// 获取状况栏高度
Rect frame = new Rect();
activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
int statusBarHeight = frame.
Log.i(&TAG&, &statusBarHeight = & + statusBarHeight);
// 获取屏幕长和高
int width = activity.getWindowManager().getDefaultDisplay().getWidth();
int height = activity.getWindowManager().getDefaultDisplay()
.getHeight();
// 去掉题目栏
// Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455);
Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height
- statusBarHeight);
view.destroyDrawingCache();
// 保存到sdcard
private static void savePic(Bitmap b, String strFileName) {
FileOutputStream fos =
Log.i(&TAG&,&start savePic&);
fos = new FileOutputStream(strFileName);
Log.i(&TAG&,&strFileName = & + strFileName);
if (null != fos) {
b.pressFormat.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);
以下是对正在播放的视频进行截图的功能代码：
private Bitmap createVideoThumbnail(String filePath) {
Bitmap bitmap =
android.media.MediaMetadataRetriever retriever = new android.media.MediaMetadataRetriever();
try {// MODE_CAPTURE_FRAME_ONLY
.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); //按视频长度比例选择帧
} catch (IllegalArgumentException ex) {
// Assume this is a corrupt video file
} catch (RuntimeException ex) {
// Assume this is a corrupt video file.
} finally {
retriever.release();
} catch (RuntimeException ex) {
// Ignore failures while cleaning up.
