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();}

根据上面@JustinMorris和@NiravDangi的回答https://stackoverflow.com/a/8504958/2232148，我们必须把一个视图的背景和前景像这样组合起来:

public static Bitmap takeScreenshot(View view, Bitmap.Config quality) {
    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), quality);
    Canvas canvas = new Canvas(bitmap);

    Drawable backgroundDrawable = view.getBackground();
    if (backgroundDrawable != null) {
        backgroundDrawable.draw(canvas);
    } else {
        canvas.drawColor(Color.WHITE);
    }
    view.draw(canvas);

    return bitmap;
}

质量参数取一个常数Bitmap。Config，通常是Bitmap.Config。RGB_565或Bitmap.Config.ARGB_8888。

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 " / >

对于整页滚动截图

如果你想要捕捉一个完整的视图截图(其中包含一个滚动视图左右)，那么在这个库中进行检查

https://github.com/peter1492/LongScreenshot

你所要做的就是导入Gradel，并创建一个bigscreen的对象

长截图=新BigScreenshot(这个，x, y);

当自动滚动屏幕视图组并在最后组装在一起时，将接收回调的屏幕截图位图。

get截图(Bitmap) {}

哪些可以保存到画廊或任何必要的用途，他们之后

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。

我已经创建了一个简单的库，从一个视图截图，要么给你一个位图对象，要么直接保存到任何你想要的路径
