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

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。

public class ScreenShotActivity extends Activity{

private RelativeLayout relativeLayout;
private Bitmap myBitmap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    relativeLayout = (RelativeLayout)findViewById(R.id.relative1);
    relativeLayout.post(new Runnable() {
        public void run() {

            //take screenshot
            myBitmap = captureScreen(relativeLayout);

            Toast.makeText(getApplicationContext(), "Screenshot captured..!", Toast.LENGTH_LONG).show();

            try {
                if(myBitmap!=null){
                    //save image to SD card
                    saveImage(myBitmap);
                }
                Toast.makeText(getApplicationContext(), "Screenshot saved..!", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
    });

}

public static Bitmap captureScreen(View v) {

    Bitmap screenshot = null;
    try {

        if(v!=null) {

            screenshot = Bitmap.createBitmap(v.getMeasuredWidth(),v.getMeasuredHeight(), Config.ARGB_8888);
            Canvas canvas = new Canvas(screenshot);
            v.draw(canvas);
        }

    }catch (Exception e){
        Log.d("ScreenShotActivity", "Failed to capture screenshot because:" + e.getMessage());
    }

    return screenshot;
}

public static void saveImage(Bitmap bitmap) throws IOException{

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 40, bytes);
    File f = new File(Environment.getExternalStorageDirectory() + File.separator + "test.png");
    f.createNewFile();
    FileOutputStream fo = new FileOutputStream(f);
    fo.write(bytes.toByteArray());
    fo.close();
}

}

添加权限

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

Mualig的回答很好，但我遇到了Ewoks描述的同样的问题，我没有得到背景。所以有时已经足够好了，有时我得到黑色背景上的黑色文本(取决于主题)。

这个解决方案主要基于Mualig代码和我在Robotium中找到的代码。通过直接调用draw方法，我放弃了绘图缓存的使用。在此之前，我将尝试从当前活动中首先绘制背景。

// Some constants
final static String SCREENSHOTS_LOCATIONS = Environment.getExternalStorageDirectory().toString() + "/screenshots/";

// Get device dimmensions
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);

// Get root view
View view = mCurrentUrlMask.getRootView();

// Create the bitmap to use to draw the screenshot
final Bitmap bitmap = Bitmap.createBitmap(size.x, size.y, Bitmap.Config.ARGB_4444);
final Canvas canvas = new Canvas(bitmap);

// Get current theme to know which background to use
final Activity activity = getCurrentActivity();
final Theme theme = activity.getTheme();
final TypedArray ta = theme
    .obtainStyledAttributes(new int[] { android.R.attr.windowBackground });
final int res = ta.getResourceId(0, 0);
final Drawable background = activity.getResources().getDrawable(res);

// Draw background
background.draw(canvas);

// Draw views
view.draw(canvas);

// Save the screenshot to the file system
FileOutputStream fos = null;
try {
    final File sddir = new File(SCREENSHOTS_LOCATIONS);
    if (!sddir.exists()) {
        sddir.mkdirs();
    }
    fos = new FileOutputStream(SCREENSHOTS_LOCATIONS
            + System.currentTimeMillis() + ".jpg");
    if (fos != null) {
        if (!bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fos)) {
            Log.d(LOGTAG, "Compress/Write failed");
        }
        fos.flush();
        fos.close();
    }

} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

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();}

注:仅适用于root phone

编程方式:adb shell /system/bin/screencap -p /sdcard/img.png

Process sh = Runtime.getRuntime().exec("su", null,null);
OutputStream os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
os.flush();
os.close();
sh.waitFor();    

然后将img.png读取为位图，并按照您的意愿使用。
