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。

如果你想从片段中截取截图，请遵循以下步骤:

Override onCreateView(): @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment View view = inflater.inflate(R.layout.fragment_one, container, false); mView = view; } Logic for taking screenshot: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { View view = mView.findViewById(R.id.scrollView1); shareScreenShotM(view, (NestedScrollView) view); } method shareScreenShotM)(): public void shareScreenShotM(View view, NestedScrollView scrollView){ bm = takeScreenShot(view,scrollView); //method to take screenshot File file = savePic(bm); // method to save screenshot in phone. } method takeScreenShot(): public Bitmap takeScreenShot(View u, NestedScrollView z){ u.setDrawingCacheEnabled(true); int totalHeight = z.getChildAt(0).getHeight(); int totalWidth = z.getChildAt(0).getWidth(); Log.d("yoheight",""+ totalHeight); Log.d("yowidth",""+ totalWidth); u.layout(0, 0, totalWidth, totalHeight); u.buildDrawingCache(); Bitmap b = Bitmap.createBitmap(u.getDrawingCache()); u.setDrawingCacheEnabled(false); u.destroyDrawingCache(); return b; } method savePic(): public static File savePic(Bitmap bm){ ByteArrayOutputStream bytes = new ByteArrayOutputStream(); bm.compress(Bitmap.CompressFormat.JPEG, 100, bytes); File sdCardDirectory = new File(Environment.getExternalStorageDirectory() + "/Foldername"); if (!sdCardDirectory.exists()) { sdCardDirectory.mkdirs(); } // File file = new File(dir, fileName); try { file = new File(sdCardDirectory, Calendar.getInstance() .getTimeInMillis() + ".jpg"); file.createNewFile(); new FileOutputStream(file).write(bytes.toByteArray()); Log.d("Fabsolute", "File Saved::--->" + file.getAbsolutePath()); Log.d("Sabsolute", "File Saved::--->" + sdCardDirectory.getAbsolutePath()); } catch (IOException e) { e.printStackTrace(); } return file; }

对于activity，您可以简单地使用View v1 = getWindow().getDecorView().getRootView();而不是mView

    private fun screenShot() {
          try {
            val mPath: String = this.getExternalFilesDir(null).getAbsolutePath()
              .toString() + "/temp" + ".png" 
            // create bitmap screenshot
            val v1: View = getWindow().getDecorView().getRootView()
            v1.isDrawingCacheEnabled = true
            val bitmap = Bitmap.createBitmap(v1.drawingCache)
            v1.isDrawingCacheEnabled = false
            val imageFile = File(mPath)
            val outputStream = FileOutputStream(imageFile)
            val quality = 100
            bitmap.compress(Bitmap.CompressFormat.PNG, quality, outputStream)
            outputStream.flush()
            outputStream.close()
        
            //or you can share to test the method fast
            val uriPath =
              FileProvider.getUriForFile(this, getPackageName() + ".sharing.provider", imageFile)
            val intent = Intent(Intent.ACTION_SEND)
            intent.type = "image/*"
            intent.clipData = ClipData.newRawUri("", uriPath)
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
            intent.putExtra(Intent.EXTRA_STREAM, uriPath)
            startActivity(Intent.createChooser(intent, "Sharing to..."))
          } catch (e: Throwable) {
            e.printStackTrace()
          }
        }

Java

  private void screenShot() {
    try {
      String mPath = this.getExternalFilesDir(null).getAbsolutePath().toString() + "/temp" + ".png";
      // create bitmap screenshot
      View v1 = getWindow().getDecorView().getRootView();
      v1.setDrawingCacheEnabled(true);
      Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());
      v1.setDrawingCacheEnabled(false);

      File imageFile = new File(mPath);
      FileOutputStream outputStream = new FileOutputStream(imageFile);
      int quality = 100;
      bitmap.compress(Bitmap.CompressFormat.PNG, quality, outputStream);
      outputStream.flush();
      outputStream.close();

      //or you can share to test the method fast

      Uri uriPath = FileProvider.getUriForFile(this, getPackageName() + ".sharing.provider", imageFile);
      Intent intent = new Intent(Intent.ACTION_SEND);
      intent.setType("image/*");
      intent.setClipData(ClipData.newRawUri("", uriPath));
      intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
      intent.putExtra(Intent.EXTRA_STREAM, uriPath);
      startActivity(Intent.createChooser(intent, "Sharing to..."));

    } catch (Throwable e) {
      e.printStackTrace();
    }
  }

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。

你可以尝试这样做，

从布局或视图中获取位图缓存 首先你需要setDrawingCacheEnabled到一个布局(线性布局或相对布局，或视图)

然后

Bitmap bm = layout.getDrawingCache()

然后对位图做任何你想做的事情。要么将其转换为图像文件，要么将位图的uri发送到其他地方。

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;
                }
