参数视图是根布局对象。

public static Bitmap screenShot(View view) {
                    Bitmap bitmap = null;
                    if (view.getWidth() > 0 && view.getHeight() > 0) {
                        bitmap = Bitmap.createBitmap(view.getWidth(),
                                view.getHeight(), Bitmap.Config.ARGB_8888);
                        Canvas canvas = new Canvas(bitmap);
                        view.draw(canvas);
                    }
                    return bitmap;
                }

我的解决方案是:

public static Bitmap loadBitmapFromView(Context context, View v) {
    DisplayMetrics dm = context.getResources().getDisplayMetrics(); 
    v.measure(MeasureSpec.makeMeasureSpec(dm.widthPixels, MeasureSpec.EXACTLY),
            MeasureSpec.makeMeasureSpec(dm.heightPixels, MeasureSpec.EXACTLY));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    Bitmap returnedBitmap = Bitmap.createBitmap(v.getMeasuredWidth(),
            v.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(returnedBitmap);
    v.draw(c);

    return returnedBitmap;
}

and

public void takeScreen() {
    Bitmap bitmap = ImageUtils.loadBitmapFromView(this, view); //get Bitmap from the view
    String mPath = Environment.getExternalStorageDirectory() + File.separator + "screen_" + System.currentTimeMillis() + ".jpeg";
    File imageFile = new File(mPath);
    OutputStream fout = null;
    try {
        fout = new FileOutputStream(imageFile);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
        fout.flush();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        fout.close();
    }
}

图像保存在外部存储文件夹中。

您可以尝试以下库: http://code.google.com/p/android-screenshot-library/ Android截图库(ASL)允许以编程方式从Android设备捕获屏幕截图，而不需要具有root访问权限。相反，ASL利用了在后台运行的本地服务，每次设备启动时通过Android调试桥(ADB)启动。

从Android 11 (API级别30)，你可以用辅助服务截屏:

takeScreenshot -截取指定显示的屏幕截图，并通过AccessibilityService.ScreenshotResult返回。

在android中截取视图的截图。

public static Bitmap getViewBitmap(View v) {
    v.clearFocus();
    v.setPressed(false);

    boolean willNotCache = v.willNotCacheDrawing();
    v.setWillNotCacheDrawing(false);

    int color = v.getDrawingCacheBackgroundColor();
    v.setDrawingCacheBackgroundColor(0);

    if (color != 0) {
        v.destroyDrawingCache();
    }
    v.buildDrawingCache();
    Bitmap cacheBitmap = v.getDrawingCache();
    if (cacheBitmap == null) {
        return null;
    }

    Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);

    v.destroyDrawingCache();
    v.setWillNotCacheDrawing(willNotCache);
    v.setDrawingCacheBackgroundColor(color);

    return bitmap;
}

参数视图是根布局对象。

public static Bitmap screenShot(View view) {
                    Bitmap bitmap = null;
                    if (view.getWidth() > 0 && view.getHeight() > 0) {
                        bitmap = Bitmap.createBitmap(view.getWidth(),
                                view.getHeight(), Bitmap.Config.ARGB_8888);
                        Canvas canvas = new Canvas(bitmap);
                        view.draw(canvas);
                    }
                    return bitmap;
                }
