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

这个方法不需要root权限，也不需要大量编码。

在adb shell上使用以下命令可以截屏。

input keyevent 120

这个命令不需要任何root权限，所以你也可以从android应用程序的java代码执行。

Process process;
process = Runtime.getRuntime().exec("input keyevent 120");

更多关于android中的keyevent代码，请参阅http://developer.android.com/reference/android/view/KeyEvent.html

这里我们用了。KEYCODE_SYSRQ，它的值是120，用于系统请求/打印屏幕键。

如CJBS所说，输出的图片将保存在/sdcard/Pictures/Screenshots

    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();
    }
  }

只是扩展塔拉洛卡的答案。您必须添加以下行才能使其工作。我已将映像名称设置为静态。请确保您使用taraloca的时间戳变量，以防您需要动态图像名称。

    // Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
};

private void verifyStoragePermissions() {
    // Check if we have write permission
    int permission = ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        // We don't have permission so prompt the user
        ActivityCompat.requestPermissions(this, PERMISSIONS_STORAGE, REQUEST_EXTERNAL_STORAGE);
    }else{
        takeScreenshot();
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        if (requestCode == REQUEST_EXTERNAL_STORAGE) {
            takeScreenshot();
        }
    }
}

在AndroidManifest.xml文件中，以下条目是必须的:

< uses-permission android: name = " android.permission。READ_EXTERNAL_STORAGE " / > < uses-permission android: name = " android.permission。WRITE_EXTERNAL_STORAGE " / >

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。

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。
