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

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。

如果你想捕捉一个视图或布局，比如RelativeLayout或LinearLayout等。

只需使用代码:

LinearLayout llMain = (LinearLayout) findViewById(R.id.linearlayoutMain);
Bitmap bm = loadBitmapFromView(llMain);

现在你可以保存这个位图在设备存储:

FileOutputStream outStream = null;
File f=new File(Environment.getExternalStorageDirectory()+"/Screen Shots/");
f.mkdir();
String extStorageDirectory = f.toString();
File file = new File(extStorageDirectory, "my new screen shot");
pathOfImage = file.getAbsolutePath();
try {
    outStream = new FileOutputStream(file);
    bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
    Toast.makeText(getApplicationContext(), "Saved at "+f.getAbsolutePath(), Toast.LENGTH_LONG).show();
    addImageGallery(file);
    //mail.setEnabled(true);
    flag=true;
} catch (FileNotFoundException e) {e.printStackTrace();}
try {
    outStream.flush();
    outStream.close();
} catch (IOException 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。

private void captureScreen() {
    View v = getWindow().getDecorView().getRootView();
    v.setDrawingCacheEnabled(true);
    Bitmap bmp = Bitmap.createBitmap(v.getDrawingCache());
    v.setDrawingCacheEnabled(false);
    try {
        FileOutputStream fos = new FileOutputStream(new File(Environment
                .getExternalStorageDirectory().toString(), "SCREEN"
                + System.currentTimeMillis() + ".png"));
        bmp.compress(CompressFormat.PNG, 100, fos);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

在清单中添加权限

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

对于支持棉花糖或以上版本，请在onCreate方法中添加以下代码

ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},00);
